Oven not heating

The oven is going thru the preheat cycle but never heats up. I had the elements checked and they are still good. Could it be the thermostat?

    After using the self-cleaning cycle the oven would not heat. This is the third time it has happened (have to clean the oven), each time after the cleaning cycle. Each time I replaced the TCO, part number 4450934, and it then worked fine. First time it happened, it was under warranty and for the repair Whirlpool replaced the circulating fan with a larger version and put in a new TCO. It worked fine until I used the cleaning cycle again.

Gallow, Whirlpool put out a service flash on this model concerning the TCO located in the back. Regarding oven wont heat up, control panel normal. It has to do with the TCO (thermostat fuse) located just under the vent in back and it's tripping. Since you had the elements checked out, Im suspecting this TCO. Usually when these thermostats open, they are non resetable and you don't have any heat at all. The best thing to do is check this TCO with a meter. If it shows open, thats probably the culprit. They recommend moving the new TCO over to the left about 6 inches so it is not directly under the vent. You are going to need help pulling the built in out just far enough to get at the TCO. The part number for it is 4450934. The service flash is 22-647. Catriver...post back.

Does the unit have enough power to run (220V), also above you only mentioned convection? So is this the only cycle you have issues with? So, bake and broil work fine? The reasons for the question are they function work together for preheat. If all you elements are having issue, then check source of power to element and relay power up at board for the issue. Did this issue start after a cycle (self clean)? Check breaker for 220V, check supply to oven 220V, check power from relay / clock for 220V. If all this is good, check the elements for 220V (use caution when doing this). Get me more information and we can solve this, I seek to locate the problem by looking for power or lack of.

I am under the assumption you understand electricity and how to work with it. If not, please seek a service person to preform these tests or repair.

Look forward in hearing back from you on the progress.

My Kenmore Elite oven will take over an hour to preheat to 350 degrees and never does get done preheating.

There's a few things that can cause this.

1. Check to see if the both that Bake and Broil elements (burners) are heating up. Check the Broil element in Broil mode.

- during pre-heat the Broil element gets cycled on and off for short time durations to speed up the heating. If the Bake element is not working, then the oven will heat, but very slowly and never reach high temperature.

2. If the elements are both working, then it's possible that you have a bad temperature sensor.

- this is a temperature dependent resistance device that should measure 1080 ohms at 70 deg F (room temp).

3. If #1 and #2 are ok, then the problem is with your oven clock/control unit. We rebuild these at fixyourboard.com.

Model FEFL78CBC frigidaire oven bottom (bake) burner won't work everything else works fine --even broiler element works fine. Just used self-cleaning cycle, which did work. Next morning oven won't heat ....

We had the same thing happen and now they came and said it was the clock that needs to be replaced. They said that controls the oven. Even though clock is on and working the function for turning on the oven is not


you may want to check your broil element
turn the unit on and wait a few minutes
see if you can feel the heat from the upper broiler elemnet
some model use both elements to preheat
i dont have your productiuon number so i cannot be sure with your model
14-20 mins is the industry standard for a 350 preheat...

My dacor oven model ECS130SBK is very slow to heat. Sometimes reaching the desired temp. after a long wait. Sometimes it never gets there.

I found the bottom element was not getting any power by using a volt/ohmmeter and a test method described elsewhere. (Shut off power, hold down COOK TIME while turning on power. then within 30 seconds press each mode you want to test and only that element/fan/etc will turn on. Cancels by itself after 30 sec.)

I traced the wire back to the relay (wire checked good) and there was no power getting through the relay although it clicked. Removed the relay board to replace it and found a cold solder joint on the "out" terminal with obvious past arcing carbon. Cleaned and soldered the pin and the oven now works normally.
WHY THE SLOW TO HEAT? The oven turns on all the elements to preheat faster and when it reaches your set temp it beeps and now only turns on the element you selected to maintain the temperature. (Bake or Convection) Our malfunctioning ovens would then cool since the element is not working properly and it must go back into preheat and keep cycling.
BY THE WAY- Don't ever use 4 hours on self clean it kills the boards and/or display. I also put a house fan in front of the oven and blow it into the lower grill to take away some of the heat on the two boards. Learned the hard way!

Preheat oven stays on and oven will not preheat

If your electric2_bing.gif oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself...

Oven Problems Electric2_bing.gif Oven is Heating Slowly or Poorly


Kenmore oven - will not heat on bake / will heat on broil

its your temp sensor. replace it and it should fix ur prob
is your bottom element connected?

Heating Elements for oven and broiler do not heat

There is four crimp connectors on the inside at the element. They can go open circuit. I would check them. There is an interna thermal fuse, when the element blows that usually goes too. Good luck
