Oven not heating KitchenAid KERC506HWH3
I have a one year and 2 month old KitchenAid KEMC308KSS03 Wall oven/microwave combination.
After a self cleaning cycle the oven would not heat again. Eveything else works fine the microwave, controls, etc.
The problem is the thermal limiter switch that KitchenAid used. It is a one shot thermal limiter that opens if the back of the oven goes above 120degrees C and does not reset when it cools down.
The KitchenAid PN is 9759243 BUT don't replace it with the same part if you have this problem. KitchenAid want $84 for this silly thing and it a piece of junk. Buy a PN 317-1368-ND from DigiKey Inc. 1-800-344-4539. This is a 120 degree C thermal limit switch but it will RESET itself when the oven cools down so if it happens again you won't have to pull the oven. This part cost s $6.60 from DigiKey and is a much better part than the original one from KitchenAid.
The switch is on the back of the lower oven, there is a cover that comes off and you will see it screwed to the back with two wires connected to it with faston terminals. It is an easy permanent fix for this problem.
KitchenAid is ABSOLUTELY NO HELP with this (as ususal).
I hope this helps.
