GE J BP27G R1AD Oven Not Heating Fully

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.

Most double wall ovens are technically two separate oven boxes. The lower oven box has its bake, boil elements, high limit thermostat and ofcourse its own oven sensor. If the lower oven box boil is working good and less heat on bake feature may suggest that the bake element is burned out and only getting preheated with boil element. Just a suggestion here

You will have to see if there is power to the element. It is possible that the relay contacts burned when the element burned out. There is a fusable link but this would shut down both the top and bottom elements. If the relay is burned out the control board will need replacing or rebuilding.

Have you checked the heating element supply voltage with a VOM? And have you checked for a popped/burned fuse to the bake element?

I'd check the control switch first, and the wireing and connections.

We have a new GE Range and the signal beeps at about 100 degrees below the temp which we have set . The dealer replaced the sensor and the control circuit, but there was no change.
A service tech from GE came to our house and explained that the new ovens have a bottom heating element which is covered and therefore heats the lower part of the oven more slowly; but the exposed upper element heats more rapidly and the sensor is located near the upper element. We were advised to wait for about 15-20 minutes after the beep before placing the food in the oven. Judging from the number of comments found online, this seems to be a feature of newer ranges.

Hi, Yes, that element is toast...

A common problem is the heating element goes bad. I have had this happen and you can see a spot on the heating element which looks different from the rest of the element (a clue).

Many ovens have two heating elements. Upper and lower. Now I am no Julia Child, but I think bake turns on just the lower heating element? And broil turns on just the top heating element????

So I suppose you might have it on bake and it is not working. Might try broil and see if that works. If yes, then you are getting power through all the controls to the upper heating element, so good chance just the lower heating element is bad.

If you don't get heat to either the upper or lower heating element, then I would suspect the wiring or a control.

So far as the heating element, you should be able to remove it and using an ohm meter, get some sort of reading if it is good (I have no idea what though). Or open circuit if bad.

Also the insulation on older ranges can "melt" back exposing live wires! This is of course very dangerous and the wiring should only be replaced with high heat range wiring which I assume you could get at an appliance store?

Or the contacts on a control/switch could be bad. I would test this with a continuity tester or ohm meter.

Many appliances have a wiring diagram down low somewhere. Or might find it online.

cdkd, there should be a TC0, on the back of the oven. Thermal cut out. You want to check to see if it is open. You will have to pull the oven out enough that you can remove the back panel cover and check it. The lower and upper oven should have one. It's a very cheap part to replace. If this TCO fails, no heat. Check this first before buying a new board. Catriver..post back.
