Tech Tip: Range External Temp Guidelines


Modern OvenSUBJECT
Underwriters Laboratories have evaluated external temperatures for ranges and have communicated the acceptable external temperatures for a range product, including glass doors. All cooking products meet UL safety standards.


Cooking on surface burners can cause the cooktop area to get hot. To minimize the possibility of burns, ignition of flammable materials, and spillage, handles of pots and pans should be turned toward the center of the range without extending over nearby surface units. Do not place or store items that can melt or catch fire on the cooktop surface.

UL and ANSI surface temperature limits for ranges
(Set oven temperature to bake at 475° F.)

Surfaces below 36 inches
Bare or painted metal: 152° F
Porcelain enamel: 160° F
Glass or ceramic: 172° F
Plastic: 182° F

Surfaces above 36 inches
Bare or painted metal: 183° F
Porcelain enamel: 191° F
Glass or ceramic: 203° F
Plastic: 212° F

Handles and knobs (475° bake only)
Bare or painted metal: 131° F
Glass or ceramic: 149° F
Plastic: 167° F

Warming drawer temperatures
Extreme caution must be used with these products. Slide-in ranges require a filler strip or back guard when the countertop cutout goes all the way to the back wall. The temperature of the air from the oven vent at the right rear surface unit (on most models), changes with the oven temperature set by the user. It is significantly lower than the oven temperature.

Surrounding exterior surfaces and materials

Make sure wall coverings and cabinets around the range can withstand heat generated by the range, up to 200° F in a room of 77° F. Before buying cabinets to install a cooking product in or around, check with the manufacturer to see that it meets this criteria. Some new cabinets have been found to “delaminate” (the formica peels off) at approximately 150° F.


A hot pot or pan (no temperature limitations) can be set on a cool part of the surface of a glass or ceramic cooktop without damaging the surface. Check the owner’s manual for that individual model; look under “Safety Instructions” for specific recommendations.

It has been proven that a pan that is not flat can cause the cooktop surface temperature to be higher. (All electric cooktop types included: solid disc, calrod, radiant, etc.) See the use and care book for types of cookware to use.
