Won't heat When I try to bake something, the oven starts to heat, then stops. Also, the display board's numbers can almost barely be seen and there's a party at our house today, and we have to use the oven today.

Re: Won't heat

As for the display problem, you'll have to replace the Oven relay board and the display head.

As to the won't heat problem, mine is doing the same thing. On mine the Air Switch has malfunctioned. I hear a steady claking sound as the Stalled Fan relay cycles on and off. When it is operating normally, it will send a steady 120V power to the stalled fan relay. When it malunctions, the 120V signal is eratic and will totally shut off after the oven reaches the mid to upper 200 degree area. Once the oven cools off, you can restart it but the same problem will reoccur.
Replace the Air Switch and maybe the Stalled Fan Relay since it has been getting over used due to the constant on and off cycles it has been going through.
Hope this helps

Baking & broiling elements won't heat after baking element burned out and was replaced.

the surge from the original element burning out has destroyed the control board if you can't hear the relays on the board clicking when you power up the elements bake or broil then its either the low voltage side of the board,if you hear clicking then the relays are working but the contacts are burned out and can't pass the current to heat the oven or briol elements

Bake element does not work during convection cooking

Hello and welcome to Fixya.

I hadn't seen your post prior to today, so perhaps you've had a remedy presented to you already.

If you have not, reply to this post and I can recommend a few test to perform that will determine the issue with your oven.

Off the top it sounds like a possible faulty convection heating element or the K3 relay on the board is defective.

I'll watch for your reply.

Oven won't heat, display out, gas burners on stove

Hello, you will probably need to pull it out and put it on something. Make sure the breaker is off to it before you test it. There is a thermostat in the very back that could be bad,check for continuity on that. Also check for continuity on the bake and broil element terminals itself,even though you have checked it to ground. If those check good,then the problems is in the control board.

GE J BP27G R1AD Oven Not Heating Fully

Hi Jeff. You should have a wiring diagram with the range. Check for an envelope on the back of the range, inside the back splash, or taped to the inside side wall of the range if you remove the lower drawer. That all being said, first check to see if the start or stop time knobs on the timer have been pushed in (and possibly turned). If the clock runs, it will clear this out within 12 hours, but on these old ranges often times the clock no longer runs. Make sure these knobs are turned until they have "popped" out or you won't get the necessary voltage where you need it. Secondly, when a bake element burns out, it can cause damage to the electrical contacts in the oven selector switch (part number WB22X5122 ) which can be tested with an ohm meter if you can find the electrical diagram. Also, the oven thermostat (part number WB21X5320 ) can be damaged in the same way. Unfortunately, these parts for these old units are not very cheap.
The little bit of heat you are getting in your oven now is most likely only from the 120 volts going to the broiler element when in Bake. During Bake, your bake element should get 240 volts (until thermostat is satisfied). Setting to Broil should give 240 to the broil element.

Err on display when I try to set the bake temperature

Usually, when an oven won't bake, it's because the bake element is burned out. The bake element is the black, pencil- thick tube at the bottom of the oven. When the oven heats, the element glows red. This element has an expected life-span of several years. It may last for only one; it may last for many more. When the element burns out, you need to replace it.
or try doing this
1. Turn the clock selector knob to OFF
2. “Tweak” the oven control by turning the clock selector knob slightly to the left (counter clockwise). This may stop the flashing message/beeping and clear the display window.
