Default Maytag Performa Stove not mantaing baking temp

I have a gas stove a Maytag Performa barely past the 5 year warranty on electrical parts (naturally), and the baking temperature inside the stove does not maintain the temperature setting, if I set the temp to 400 degrees via the electrical setting switch, it will reach that temperature and then begin to decrease down to about 200 degrees and not rise again, so I switch from bake to broil and once the broiler flame ignites, which usually takes awhile, I switch back to bake and only then will the temperature maintain the desired 400 degrees once reached and stay there, i'm not sure if this is a problem with the electrical switch or possibly grease in the jets, i tried using the self clean feature several times to clean out grease possibly from the jets but that didnt solve the problem, i have not spilled grease inside nor is the stove at all dirty, the stove uses one compartment for baking and broiling, the broiling flame from above and the baking flame from underneath the pan beneath the grill, any thoughts on how to fix this myself?

Hi,

Model#?
http://www.applianceaid.com/model-number.php Some model# helps.

A weak ignitor can cause temp issues...

Could also be a problem in the stove's logic circuitry, which clears when you switch to broil.
You could cut power temporarily to the oven and see if that also clears the bake temp problem.

If you're not up to measuring ignitor current draw I'd start getting prices for the logic board/controller part and the ignitor.

Maybe, but how does your procedure for clearing the fault affect this component?
And if the parts guy says he hardly ever sells one of these, it may be a less likely candidate.

It may also be a coincidence that your procedure works, unless you can consistently clear the problem by doing it. The problem may be time-dependent instead of being affected by control settings.

There are several test points in the oven that you should monitor to try to isolate the problem. Connections can also fail.

Since the problem is not intermittent and the oven is not tripping its breaker, etc., you have a good chance of solving this one.

Do not cause a gas explosion.
It was not that long ago that a HO and his wife landed on the lawn at 3 AM because of his faulty dryer install. Since their house was demolished they are now "judgement proof", all in a flash. And nearby houses took some shrapnel, also.

I'm appreciative of the tip, should I close the gas before attempting to change the temperature sensor probe, or the ignitor switch?

Probably not necessary if replacing temp sensor probe though?

"You could cut power temporarily to the oven and see if that also clears the bake temp problem."
How exactly is that done?

I also read somewhere that some temp sensor probes require calibration via the electronic control and might not be defective, not sure if its this model?

Lets face it, it's hit or miss with any of these replacements

Ohming the oven temp sensor is a good idea, still sounds like a weak ignitor to me.

1000-1100 ohms at room temp for the sensor.


Ignitor, glow bar Manufacturer Number 74007498


Oven sensor kit, short Manufacturer Number 12001655

With the gas danger, you have to be careful not to defeat any of the oven safeguards that prevent gas mishaps.
I guess the worst outcome would be the gas valve being on and no ignition being called for by the oven logic circuitry.

To cut power, turn off the oven breaker for a few seconds and then back on.

BTW, the more measurements you take, the less role probability plays in getting a favorable outcome for your repair adventure.
Then it's up to you to minimize your errors in logic, see "logical fallacies" on Wiki.

Jeff;
I dont have an ohmeter, however I took the bottom pan off and set bake to 350 degrees, I watched as the ignitor got bright red and lit the flame, but at a temp of about 200 degrees the flame went out and never came back on. Wouldnt that indicate the temperature sensor probe is off somehow??
Thanks
