JBP66G W1AD Oven won't get hot enough

your Maytag range has only a single heating element located at the top of the oven, it is likely a "broil" element, which is used primarily for cooking food close to the top of the oven. The lower heating element, which is typically used for baking and roasting, may be hidden beneath the oven floor or located at the bottom of the oven.
If your oven is not getting very hot, it is possible that the broil element is malfunctioning and needs to be replaced. However, if the oven is not heating evenly or is not getting hot enough to cook food properly, it may be a more complex issue related to the temperature sensor, the control board, or other components.
To diagnose and repair the issue, it is recommended to have the range serviced by a qualified technician, who can properly identify the model and locate the faulty component. The model number of your range can typically be found on a label inside the oven door, on the back of the range, or on a storage drawer beneath the oven.

the upper element only comes on when you broil or clean with selfcleaner. the bottom comes on when you are baking, it sounds like your bottom element is bad.

Phil. If you do not have voltage at the element, then the Electronic Oven Control ( EOC ) has failed. Part number # 5701M403-60

In order to check for the correct voltage at the element you will need to remove power and pull the range out of its installed location and remove the back panel of the range to gain access to the wiring and element. CAUTION ! I cannot stress this enough ! There are dangerous voltages in this area!! After the panel has been removed, return power to the range,set the lower oven to bake, and check the voltage at the element. You should find 220-240 volts between the element terminals with them connected to the element. If you do not have the proper voltage then you will need to replaced the EOC.

Sounds like the bake element - do a visual check and look for blistering or cracking. If it looks normal, unplug the oven (or flip breaker for wall oven) and then you can remove the screw holding the element and pull it forward enough to unplug it and do a continuity test with a multimeter. If it test bad, replace the element.

it could be the oven temp sensor rod located near the top of the inside of the oven,or possibly the bake element has a hot spot on the element and can no longer pass enough current thru this spot to correctly heat to your settings a hot spot on the element will look discolored in this area

Have 10 year old fridgidare elec.oven. Model no.FEF355ASE and both bake and broiler have stopped working have power and ohm's are good. Whats next ?

It sounds like you burned out the oven heating element control board.

I was wrong (I think).  the baking element probably was burnt out as the repairman said.  He replaced it and I thought selfclean still wasn't working.  In fact, I think I just had to give the self-clean function more time.  Also, I was judging by smell.  We have become used to a bad odor during self clean which was missing when it was broken and still missing after the repair.  Bottom line, the oven was clean after the baking element was replaced, sans smell.

This may be the thermostat control.
I would find someone to check the resistance of the element with an ohm meter.
It should read 15 to 20 ohms.
Put the timer on manual first and try the oven, because it could be the timer.
It would be ok to just replace the bottom oven element because most of the time it is a faulty element.
