Cleaning & Care

Cooktop
Which cleaners should always be avoided when cleaning gas appliances? Do not use flammable cleaners.
How to clean the surface of my range. Stainless steel surfaces - Clean stainless steel areas by using mild soapy water and a soft cloth. Wipe in the direction of the stainless steel grain when washing and drying. Rinse with water and wipe dry to avoid watermarks. Do not use cleaners that are abrasive or contain chlorine since both are corrosive to stainless steel. For added shine, apply a stainless steel conditioner and wipe off the excess with a soft cloth.

Visit the How-To Videos page and watch the "Cleaning Stainless Steel Appliances" video to learn more.

Warning: Stainless steel conditioners and cleaners can have negative effects on materials other than stainless steel. Do not apply stainless steel conditioners and cleaners to control markings, labels, logos, black or smudge-proof stainless steel, and appliance interiors.

Porcelain surfaces - Immediately wipe up acidic spills like fruit juice, milk, and tomatoes with a dry cloth. Do not use a damp sponge or cloth on hot porcelain. When the porcelain is cool, clean it with hot, soapy water and a soft cloth. Rinse and dry. It is normal for porcelain to show fine lines with age due to exposure to heat and food.

Painted surfaces - Wash with hot, soapy water and a soft cloth. Rinse and dry. Do not use powdered cleaners, steel wool pads, oven cleaners, and other abrasive cleaning materials.
How to clean the grates. Turn off the cooktop. Remove all pots, pans, and utensils. Carefully, remove the heavy grates once they have cooled down. Wash them with mild soapy water and a soft cloth. Rinse and dry.
Acidic and sugar-laden spills deteriorate the enamel, so remove these spills as soon as safely possible.

Abrasive cleaners can mar the grates. Do not clean them in a self-cleaning oven.

Visit the How-To Videos page and watch the "How to Clean Gas Cooktops" video to learn more.
Over time, the grates become shiny. There is nothing wrong with the grates. This is caused by using inexpensive, non-coated, aluminum pans. The texture of the grates can remove bright, shiny aluminum from the pans because the pans are non-coated. The shiny aluminum fills in the areas on the grates and makes them shiny.

If you use non-coated, bright, non-colored, aluminum pans, try to gently clean off the shiny spots with a clean, new Scotch-Brite abrasive pad or a coarse, steel wool pad.
How to clean the burners. Burner caps - Remove all pots, pans, and utensils. Turn off the cooktop. Remove the grates once they have cooled down. The grates are heavy so use care when handling them. Use hot, soapy water with a soft cloth, rinse, and then dry. Non-abrasive and liquid cleaners may also be used. Dry the burner cap thoroughly after cleaning. Do not soak the burner caps.

Burner bases - Make sure the cooktop has cooled completely before cleaning the burner bases. Clean the burner bases with hot water, mild detergent, and a soft cloth. Use a stiff nylon toothbrush to clean the port openings. Do not scratch or gouge the port openings. Rinse and dry.

Gas igniters - After the igniters have cooled down, carefully wipe the igniters with a cotton swab dampened with water. Gently scrape the soil off with a toothpick. Avoid exposing the igniters to excessive water, as a damp igniter may not light up. Remove any lint that may remain after cleaning.

Visit the How-To Videos page and watch the "How to Clean Gas Cooktops" video to learn more.
How to clean the control knobs. To remove the knobs, simply pull them straight forward. Use hot, soapy water with a soft cloth. Rinse and dry. Do not soak the knobs or use abrasive cleaners and scrubbers.
Oven
How to clean an oven that does not have the self-cleaning feature. After the oven has cooled, use hot, soapy water and a nonabrasive sponge. Only use mild cleaners such as Soft Scrub, Bon-Ami, or Ajax. Rub lightly with a nonabrasive sponge, rinse thoroughly, and dry with a soft cloth.

If food has burned onto the oven and is difficult to remove, use a mild cleaner with an SOS or Brillo pad and rub gently. SOS and Brillo pads may scratch the porcelain. This does not affect oven performance.

We do not recommend using oven cleaners because they can remain on the oven porcelain after being wiped off and can emit odors during cooking.
How to activate the oven's self-cleaning feature. All models have slightly different instructions. Please refer to your owner's manual to learn how to self-clean your oven. If you do not have an owner's manual, you can download it here.

Before activating the self-cleaning feature, make sure to remove all racks and pans and wipe away loose soil / debris from the oven cavity. Visit the How-To Videos page and watch the "Preparing Your Oven for Self-Cleaning" video to learn more.
The oven is not self-cleaning properly. Before running the self-cleaning feature, allow the oven to cool, wipe away loose soil / debris or heavy spills, and remove the racks and all other accessories from the oven. Set the oven to the maximum self-cleaning time if the oven is badly soiled.

Visit the How-To Videos page and watch the "Preparing Your Oven for Self-Cleaning" video to learn more.
Can I use an oven cleaner for my self-cleaning oven? No, we do not recommend using oven cleaners or other chemical cleaners for self-cleaning ovens. The porcelain surface is smooth and these types of cleaners may cause surface damage.
How to clean the oven window and fiberglass gasket. Oven window - Use hot, soapy water and a nonabrasive sponge. Squeeze most of the water out before wiping. Rinse the glass and dry.

Fiberglass gasket - Do not clean the fiberglass gasket.
How to clean the oven racks. Flat racks - Wash with hot, soapy water and a soft cloth. Rinse and dry. Do not use the self-cleaning feature to clean the racks because they will lose their shiny finish and may not glide smoothly. If this happens, wipe the rack edges with a small amount of vegetable oil and then wipe off.

Telescopic racks - Wash with hot, soapy water and a soft cloth. Rinse and dry. Do not use the self-cleaning feature to clean the racks. Avoid getting cleaning powder or residue in the telescopic slides. Re-lubricate the telescopic slides as needed by using high-temperature food-grade lubricants.
Steam Oven
There is limescale in the steam oven. You will need to descale your oven. Run the DESCALE program. Refer to your owner's manual to learn how to activate this program. If you do not have an owner's manual, you can download it here.

Accessories
How to clean the grill and griddle. Grill - Clean the grill after each use. Place the grill grate into a sink and pour boiling hot water over the grate. Lay a dishtowel on top of the grate and pour more hot water over the towel. Allow the water to soak into the residue. Scrape away the debris with a soap-filled scouring pad. Rinse and dry.


Griddle - Wipe the griddle surface with warm, soapy water. Then, rinse with warm water. Wipe dry with a soft cloth. To clean the grease tray, remove the tray after the grease has cooled. Discard the grease into a grease-resistant container for disposal. Wash the grease tray with warm, soapy water. Rinse and dry. DO NOT clean any part of the griddle in a self-cleaning oven.

To season the griddle, spread a small amount of vegetable oil evenly while heating (avoiding corners). Bake the griddle plate in a 180°C (350°F) oven for one hour. Allow the griddle to cool. Repeat this process two more times and re-season as needed. Seasoning will help protect the griddle from rusting and prevents foods from sticking to the surface during cooking.
How do I protect the wood block accessory cover for the griddle from absorbing stains? Protect the wood from harboring soil and bacteria by applying unscented mineral oil to the surface. Use small amounts of oil and repeat until the surface does not allow the soil to penetrate. Do not use any other types of oil for this function, as it will turn rancid over time. Reapply after scrubbing with detergent and hot water.
How do I clean the ceramic briquettes and the tray I purchased for my range? Tray for ceramic briquettes - Wash the tray with hot water and mild detergent. It can also be washed in the dishwasher.


Ceramic briquettes - Here's how to clean the ceramic briquettes:

  • 1. Gently place the grease-saturated ceramic briquettes in a 5.5-liter or larger pot.
  • 2. Fill the pot with clean water so that all briquettes are covered at least .5" deep.
  • 3. Bring the water to a steady boil and then continue to boil for 10 minutes.
  • 4. Remove the pot from the heat and let it cool to a safe temperature.
  • 5. Remove the briquettes from the water and pat them dry with old towels or paper towels.
  • 6. Allow the briquettes to air dry for at least 2 hours. Some visible grease stains may remain on them after cleaning.
  • 7. Reassemble the clean, dry briquettes back into the tray.
CAUTION: The ceramic briquettes must be replaced when they begin to turn black. This means that they are saturated with fat and may smoke heavily during operation or the fat may catch fire.

How to clean the oven's broiling pan and grid. Wash both with hot, soapy water and a soft cloth. Rinse and dry.

Do not use the self-cleaning feature to clean them.

Usage & Operation

Cooktop
The burners do not start. There are several solutions for this problem:

  • The main gas supply may not be turned on. Make sure it is turned on.
  • Check the power supply and make sure the unit is plugged in and the circuit breaker has not tripped.
  • Make sure the burners are properly positioned.
  • The igniters may be dirty. Carefully wipe the igniters with a cotton swab dampened with water after they have cooled down. Gently scrape the soil off with a toothpick. Avoid exposing the igniters to excessive water, as a damp igniter may not light up. Remove any lint that may remain after cleaning.
  • Ignition will be quicker if a cooking pan is on the grate. Ignite the gas at full and once alight, turn it down to around 50%. It should lock on within 6 seconds.
  • Does the burner click when the burner knob is in the ON position? If yes, you may have a wiring issue at the outlet that the appliance is connected to. Turn off the main gas supply and contact a qualified electrician to fix this.
  • Does the burner click when the burner knob is in the OFF position? If yes, check for the following:
    • 1. Check to see if the burner cap is properly placed and the igniter is not wet or dirty. Clean and dry the igniter if necessary.
    • 2. Check to see if the regulator supplied with the unit is installed properly. The arrow on the regulator should be pointing to the appliance. Please call a professional installer or schedule a service visit if the regulator has not been installed properly.
The burners keep making a clicking sound or there is intermittent sparking. There are several solutions for this problem:

  • The burner caps have been moved. If so, make sure the burner caps are properly positioned.
  • The burner ports may be wet or clogged with food particles. Make sure the ports are dry and clear clogged ports with a wire or straightened paper clip.
  • The igniters may be damp. If so, dry the igniters with a dry cotton swab and remove any lint that remains after drying.
  • The gas shut-off valve may be off. Check to make sure it is on and that the gas supply to the building is not off.
  • This can also be caused by air movements or gusts in the room. Make sure there is no draft in the room.
For cooktops purchased after September 2018, the ignition spark operates continuously if a knob is held down past the child lock position.
The ignition spark operates continuously. There are several solutions for this problem:

  • The knobs may be in the LIGHTING / SPARK position. Turn the knobs to the OFF position.
  • Make sure there is no draft in the room. Select models have a re-ignition function, which is part of the flame recognition feature. The re-ignition function will attempt to reignite a flame that has been blown out or disturbed.
  • This may be caused by the presence of water due to cleaning the cooking surface with excess water or water boiling over and entering the appliance. This problem will resolve itself once the cooking surface dries.
  • If you have tried all of the above and the problem continues, you will need an authorized servicer to dismantle the appliance and repair it. You should never attempt to dismantle a gas appliance unless you are officially qualified to do so. Please schedule a service visit.
For cooktops purchased after September 2018, the ignition spark operates continuously if a knob is held down past the child lock position.
The igniters spark even though the cooktop is turned off. When the electrical power connection has been activated at the first power-up or reconnected after an outage, the igniters may spark once or twice even though the cooktop is off.

Make sure all burner knobs are not stuck or pushed down. This will cause sparking in the OFF position.
The flames go out unexpectedly, are too high, or are uneven. If the flames go out unexpectedly, make sure there is no draft in the room.

If the flames are too high or uneven, there are several solutions for this problem:

  • The burner caps may not be installed properly or may have been moved. Make sure the burner caps are properly positioned.
  • The regulator supplied with the unit may not be installed. Please ask your professional installer to install it or schedule a service visit.
My gas burners have the automatic re-ignition feature. Occasionally, one burner will not light while all the others do light. The burner cap is out of alignment. Adjust the cap so that the tabs fit into the notches on the burner base.
What is the Star™ Burner and ExtraLow®? Star™ Burner - It is a 3-in-1 burner that is exclusive to Thermador and features high performance, 5-point design, and ExtraLow® burner capability. The re-engineered Star™ Burner provides unsurpassed flame spread, faster time-to-boil, and rapid recovery time. Designed in a star shape, it provides more even heat to your cookware.

ExtraLow® - This feature keeps a consistent or low simmer, which prevents your food from burning or scorching.
Installation & BTU
Can I order a Natural Gas or LP Gas range? Yes. All gas ranges are factory Natural Gas or Liquid Propane (LP). Dual-fuel ranges are factory Natural Gas.

Click here to learn how to purchase an LP Conversion Kit for your range.
Do I need to install the anti-tip bracket? The anti-tip bracket is not needed for 48” Harmony units. However, the anti-tip bracket is needed for all other Thermador units. You may be held legally responsible if the anti-tip bracket is not installed and for any damage or injury that may occur.
What are the BTU levels of Thermador ranges? The BTU levels vary depending on the model. Refer to your owner's manual for this information. If you do not have an owner's manual, you can download it here.

The Professional® Series of ranges and rangetops have higher amounts of BTUs than the Masterpiece® Series gas cooktops.
Oven
When is it necessary to preheat the oven? Preheat delicate foods that have short baking times, such as cookies, cakes, and muffins. These types of foods need more precision timing for good results. Conversely, roasts and casseroles do not require as precise timing.

Different baking modes require preheating. Refer to your owner's manual to learn which modes require preheating. If you do not have an owner's manual, you can download it here.
The oven light does not turn off. Check for any obstructions in and around the oven door and check to see if the hinge is bent.
There is warm air, steam, or smoke coming out of the oven vent. Warm air and steam are normal. Do not block the vent. Warm air or steam will come out of the oven as part of the cooling process.

If there is smoke coming out of the oven during initial use, this can be from factory oils. These will burn off. Rid oils faster by turning the oven on for 15 more minutes or by wiping the oven with hot, soapy water before use.
The oven door will not open. Check to see if the oven is still in the self-cleaning mode. The door latch will release when the oven cools down.
Should I leave the oven door open while broiling? No, this is not necessary. Make sure the oven is closed during broiling and this will reduce the amount of heat in the kitchen.
Convection baking information. An oven that has a fan, which constantly recirculates the heated air has convection mode. This moving air strips away the natural thermal barriers that surround food and allows the heat to start cooking sooner. It will dry the food's outside surface, while the inside remains moist.

To get the best results from convection cooking, use low-sided, metal pans so that the heat can reach as much of the food's surface as possible.

Refer to your owner's manual to learn which rack position is best for the dish you're cooking. If you do not have an owner's manual, you can download it here. If you want to bake with 3 racks in convection mode, we recommend baking on rack positions 1, 2, and 4.
Baking & Cooking
Baked goods are overdone or underdone. This may be due to an error in the baking technique (human error) or the oven may not be performing optimally. Performing the Biscuit / Cookie Bake Test will determine if the cause is a human or oven error. We use this test to help develop our ovens.

Purchase unbaked Pillsbury Biscuits or Pillsbury Sugar Cookies and follow the instructions on the packaging.

  • If the biscuits / cookies turn out well during the baking times noted on the package, the oven is performing properly and does not need a service visit.
  • If the biscuits / cookies turn out overdone or underdone during the baking times noted on the package, the oven needs to be checked by an authorized Thermador servicer. Please schedule a service visit.
Visit the How-To Videos page and watch the "Checking Your Oven's Temperature" video to learn more about this bake test.
The food is cooked unevenly. There are several solutions for this problem:

  • The base of the pan may be warped. Use a different pan.
  • Make sure to place the pan over the center of the burner so the heat is evenly distributed.
Ventilation & Odors
Can I install a downdraft behind a Professional series range? No. We strongly recommend a Professional series hood with all Professional series ranges.
Do I need ventilation over my range? Yes, all ranges need ventilation.
There is a gas odor coming from the cooktop. There are several solutions for this problem:

  • The burner knobs may not be completely turned off. Turn the knobs to the OFF position. If the smell does not go away after doing this, turn the main gas supply off and schedule a service visit.
  • It is normal to smell gas for up to 4 seconds after igniting the burner. If the smell does not go away after ignition, turn the main gas supply off and schedule a service visit.
  • The burner caps may be out of alignment. After the cooktop has cooled, adjust the caps so that the tabs fit into the notches in the burner bases.
