Oven Temp Problems

I have a Maytag LER3330AAZ that I recently replaced the bake element on. The element had caught fire and broke. I figured it was just from food on it but after replacing it I see there may be a bigger problem. Upon first use after replacement I set the oven at 350 degrees but noticed that after awhile it seemed much hotter than that. I changed the setting from 350 to 375 it instead of having to heat up more it instantly changed to 375. Bumped it up by 25 degrees several times and like before it immedialtely changed. The oven was set at 350 but it was actually over 450 degrees and rising. I've looked at the parts list and can't figure out what would be the next part to replace that would be causing this problem. I see no thermostat. Can any one help ?

    I figured I'd try the unplug for 10 minutes reset option coolguy recommended first.

    Upon starting it back up I figured I would watch everything so I set the oven to 200 degrees and watched the temperature display go to 200. At 200 it gave the beep that it normally would when reaching the set temp but there was no other sound and the bake element stayed red hot. I gave it about a minute but it was obvious it was going to keep on going. I changed the bake temp to 225 and it instantly registered at that temp, changed it to 300 and it registered at 275. It kept going to 300 and gave the beep but again it was obvious it wasn't shutting the element off when the temp was reached.

    It seems like the temp sensor is registering the right temp but the oven is not responding by shutting the element off when reaching that temp.

    Do you still think it is the temp sensor ?

    I am basically an amatuer do it yourselfer and would certainly have no problem changing the sensor but I am not sure I could delve into the circuitry if needed.

    I can not find any info on a thermal fuse from the parts list.

    Which element is it that you want me to replace. I have already replaced the bake element.

    P.s a termal fuse is like any other fuse, ie if you are getting power at element(as you are) it is not the fuse. It can only be the temp sensor (thermistor) or it could be the circuit that powers the element not receiving the temp sensors signal or just not switching off when it does

    Temp sensor reads temp and sends that info to a control board to allow unit to maintain a set temp



    From what you expain it does sound like the sensor is doing it's job and fault seems to be control board but I'm not sure on that, it may well just beep when temp display reads as set, not actual temp senced.



    Without a service manual, to check voltage on board, I would of changed element (as I beleive you have done) and temp sensor, then I'd go for board.



    Put a multi meter and check resistance of sensor, it should be neither short nor open circuit and resistance should change with temp of it.. Element should test neither open or short too.



    Thermal fuse if fitted should read short



    I cant see the logic of changing the thermal fuse, its job is to cut power if its temp rating is exceeded. Once it reach's over temp it would go open circuit, and no power would not go to element until it was replaced.

Hi,

the problem can be with the thermal fuse .if not then If the switches are work in then you will have to replace the clock control. Check the switch with a meter.

Check the wiring.

Also try reseting the oven by switching the power off for up to 10min

Regarding the thermal fuse I would recommend to replace it one more time and not to use the Self clean any more until you will perform all checks and repairs according to the service pointer.
And one more thing if u have ever used the broil method you also have to replace the broil heating element due to low resistance.
The thermal fuse is located at the back of the oven..

Just replace the two things i.e. Thermal fuse and the Bake element.

You can get the parts from HERE
Goodluck,
Please don't forget to rate me as fixya..

    I don't think it is the sensor.I would like you to first give a try replacing the thermal fuse and the element..
    Most of the time this works.

No power to upper oven 'bake' heating element.


Sounds like you have it figured, need to spend some moola..........

You can ohm out the sensor to the oven should be about 1100 ohms at room temperature.((the sensor is the little rod with two wires attached to it sticking in the oven, as temps change resistance changes which is read by the board) The upper and lower oven sensors are probably the same,you could just swap them to test, but probably not necessary,might also be confusing if you do not do a lot of testing on a regular basis. Remember to unplug unit for safety.

The bake element if it was not bad should be about 20 ohms, bad would read open........

Installer either did not do the job right OR when the coils broke they shorted in a manner that fried the oven control. The installer SHOULD have verified proper operation before they left your premises.

Baking element not working


Hi, UNPLUG the oven! Remove the screws that hold the element in and pull it toward you. Hopefully they were kind enough to give you plenty of wire to pull it out. Then just unplug old element and plug in new one. Some models have a screws on the element to hold the wire on to it.
I hope this helps.
Please let me kow if I can assist you further.

Thanks
Vic
