Question about GE JKP86 Electric Double Oven

Open Question

JKP86 oven/microwave The oven will not heat.

I have a GE JKP86B0F2BB

Neither the oven element or the broil elements will heat.

All of the functions on the control panel seem to work. You can turn it on and the fan starts but it just never heats.

The microwave works fine.

    I just fixed the same problem on mine. I replaced the controller... about $170. Make sure first it is not the thermal fuses/cut off switches.

SOURCE: GE Wall Oven - No heat (broil or bake)

On appliances like this only the heating elements use 220 volts. things like the clock, fan, etc use 110 volts. That is why some things work and other do not. Start at the breaker, sometimes a double pole breaker will have 1 side tripped, but will look perfectly fine. switch the breaker all the way to off then re-set. If nothing changes follow the power to the appliance remove the panel and look for some fuses, check to see if any are blown. Also sometimes the microwave will have a separate power source even though its built in to the same appliance. So that's not always a good symptom to follow.

SOURCE: GE Oven bake element not work

It sounds like a problem with the selector switch. You have to remove the back panel to get to the back of the switch in the head unit, and find what wire goes from there to the bake element. With a meter set on 240ACV, or whichever setting is on yours that's HIGHER than that i.e. 400ACV, with the red probe on the terminal and the black one going to ground, see if you are getting 210-240 through it. If so, then it's either a faulty neutral wire connection (the other wire coming out of the element) or the selector switch. Hope this helps.

SOURCE: GE JTP 1580W288 Set oven to Bake, switches to broil at bake temp

The F2 Error code means the oven has detected an excess temperature condition. Most often this is due to a bad temperature sensor - the sensor costs about $75 from an online repair site. 
How to remove and replace the temperature sensor. In most GE ovens, when you open the door, you'll see the rod-shaped temperature sensor sticking out of the back wall at the upper left. It's about six inches long and a bit more than 1/8" in diameter, held in place with two screws. 

Turn off the circuit breaker (built-in ovens) or unplug the range before attempting the replacement. 

The replacement sensor will come with instructions, but basically it's a matter of removing the sensor, pulling out the wires to where they are connected and disconnecting them. You may have to snip. The replacement sensor will come with high-temp wire nuts to hold the new connection. Polarity doesn't matter; it's a straight resistance thermocouple. Hook it up, be sure you poke the connections back far enough so that they're on the other side of the thermal insulation and not resting against the back of the oven. 

If you continue getting the F2 error after replacing the sensor, then the problem is likely in the control module - this is the circuit board behind the keypad and clock. 

You'll need to remove the decorative bezel to get behind the control panel. Remove screws and set off parts in order - it's not complicated. Once the bezel is off there are two more screws that hold the panel in place. Then you can lift the panel up about a half inch and pivot it forward toward you. You'll see a bunch of wires going to a circuit board. 

On the panel you will notice some black plastic boxes that say "Potter & Brumfield" on them. These are relays. Check the relays - slide the black plastic cover straight up to expose the coil and the contacts. The coil, when energized, closes the contacts - look at all the relays. You can manually close the contacts with your finger (be gentle). If the contacts of one of them are stuck, they might be welded together. You can fix the problem by prying apart the welded contacts gently with a knife blade. Take some time to gently polish the relay contacts with a folded bit of fine grain sandpaper - this will get some more life out of them. Be gentle and careful - the relays aren't complicated but if you bend the contact or rip it out, you'll have to replace the controller, which will set you back a couple hundred dollars. If you unstick and burnish the relays, they will probably eventually weld together again as the rough spot will spark, but when you burnish them with sandpaper they should be good for some more life before they need to be replaced. 

If the problem isn't the temp sensor or welded relay contacts then the problem is obviously somewhere else, but temp sensor and relay contacts will account for the lion's share of F2 errors. 

Once again, be safe, be careful, be gentle. Ovens are not very complicated and they're tough, but always exercise care. Always disconnect electricity before messing with them.
good luck,

What is causing my ge single wall oven with built-in microwave oven not heating, only the fan runs?


Is it the microwave or the oven that is not heating? If the microwave is not heating it is more tan likely the magnetron. If the oven is not heating it could be the element or the control board.

I have a GE JKP86-27 oven. Neither the bake or broil work. Microwave works fine. Controls come on for oven.


I, too, have the GE -JKP86. Microwave over oven. My oven would not heat up on bake or broil. Elements checked good, no fault codes. This is how I fixed mine: Shut off power at the box. Remove unit from cabinet. I placed mine on a chair. Remove cover(s) until you expose the circuit boards behind the control consol . The top board is behind the microwave controls, the bottom is behind the oven controls. Remove the bottom board by removing 4 screws. I take pictures with my smart phone, even some video. Helps me remember how everything goes back together. BE SURE THE POWER IS OFF, HIGH VOLTAGE IN HERE! One of the screws is hard to see. It is behind the ribbon connector. Unplug everything carefully. You will see a red and an orange wire north and south of a small relay. You must unclip the circuit boards from each other. Look for a missing drop of solder on the back side of the board with the relay. You will find it underneath where the red wire connects. Mine ( looking through a magnifying glass) looked like a crater with a wire sticking up out of it. It had overheated and the solder dripped out. The joint is inadequate. I cleaned and resoldered it with a nice blob. Reassemble and check. I just left mine on the chair. Power on. Select bake, 300, start. You should here the relays click and after about 45 seconds you'll see the bottom element glow. After one minute the relay clicks again ant you'll see the top element glow. They alternate during the preheat cycle. Put it all back together and shove it all back in the hole. Hope this helped!

JKP86-27 neither heating element (broil or bake) is working. Other controls and microwave work fine.


In my case the problem was the solder around the pins of the DLB relay heated up and melted away from the pin. I found this info on another post. I put more solder on and built it up to the top of the pin to provide more metal there.

Update 8/27/2016
I've found other similar problems, e.g. on a Bosch dishwasher. The symptom is solder is vaporized on relay pins. One poster said if the relay contacts wear and increase their resistance this will cause the pins on the circuit board to overheat and vaporize the solder. So if this is the case just adding more solder may only add additional time. The true fix would be to replace the relay to solve the overheating problem. Nevertheless it's been four years since I added solder and it's still working fine.

I also had a problem like this with my Craftsman garage door opener. It was flaky- it would sometimes just blink and then stop (and it wasn't the obstruction sensor). When I took out the circuit board I found a poor solder joint. Some posters also said the pins on the circuit board connectors could fatigue and stop making good contact (in this case you have to bend them to make good contact again). Likewise the wall button/IR motion sensor started acting up and I found resoldering some pins fixed it. So loose solder or connector issues might be common.

GE Profile JTP85 (installed 1998). The lower heat element in the lower oven will not heat. I can make the upper element heat up by using the BROIL function, but neither element gets warm on BAKE.

I have a ge jkp86 electric oven the oven will not heat up .the microwave works and all displays work


First thing that comes to mind is to make sure you are getting the correct voltage to the oven, you need 220 / 240 volts, check your breakers, fuses ,etc.
It is possable for the microwave oven to operate even if the power supplied to the oven is only 110 volts, but that low of voltage is not enough to power up the ovens heating elements.
If all seems well there, then maybe the oven element has failed / shorted ?
Good luck !
