GE JKP27 F2 error

I have a GE JKP27 double wall oven and after 20 minutes of operation I get an F2 error code on the display for the top oven.

 

I start the oven and set to 400, the bake element glows red.  Eventually the oven reaches temperature and the Bake element stops glowing red. When the temp in the oven drops to about 370 (measured with thermo couple) the broil unit starts to glow red, the oven temp rises to about 675 and the F2 error code appears.  The broil element never appears to shut off and the bake does not seem to come back on after the initial preheat.

 

I have checked the resistance of the oven sensor, it is 1.093 K ohms at room temp.  I also heated it and watchrd the resistance increase as the temp increases (about 1.768 k ohms at about 408 degrees).  I also checked this for loose connections, but it looks good. So I think this is ok

 

I have verified the fan works, the Fan thermal switch in N.O as it should be. I verified the thermal switch closes at about 215 deg and reopens around 137 deg. I think this is working ok.

 

Finally I checked out the lock motor circuit.  Thermal switch is N.C. as it should be, switches sensing lock/unlock are operating correctly.

 

I checked the broil relay contact and they are not welded shut.

 

I think the only thing left is something in the ERC, but before I spent the $$ I thought I would ask if I missed something. 

 

Any help would be appreciated.

 

Thanks,

 

John

    Bake element will; not work however the broiler element works no matter if you set the oven to bake or broil

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......,

F2 Oven over temp - exceeded 590F with door in unlocked position or 990F with door locked If actual temp condition occurred, look for welded relay contacts or high resistance connection or any cause in the oven temperature sensor circuit

Installation instructions and manual


Most of the installation manuals for GE appliances are available on their support page: http://www.geappliances.com/ge/service-and-support/literature.htm . I found several double wall oven models with the JKP27 designation. However, the G0J4BG does not fit as part of the model number. There should be 4 letters after JKP27 in the model number. These letters primarily indicate the color of the exterior. For the JKP27 models, the installation manual says that the cut-out should be 32 1/2" above the floor. The depth has to be 23 1/2". The cutout width should be between 25" and 25 1/4" (these are an absolute minimum and maximum). The cutout height should be between 27 5/8" and 28 1/8".

The direct link to installation manual for one of these ovens is here: http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=003675840.PDF . See page 6 for the cut-out dimensions.

I hope this helps.

Ge oven jkp27 code f5


Hello Donald,

The F5 error code means that the control board has detecteda error within it self and theirfore the control(also called clock or EOC) needs to be replaced. The F5 error code can be cleared by pushing the cancel/off button and if it returns a short time later their is defiently a malfunction inside of the clock and it would need to be replaced.

GE model # jkp27 error code F1 what should I do?


Hi ssantillo,

Usually F1 error code means that either the touch pad or the oven control (also called clock or ERC) is defective and needs to be replaced. If this fault code cannot be cancelled, replace the oven control (also called clock or ERC), touch pad, or both.

Hope this helps.

Thank you for using FixYa.

The read on display is f2 and beeping


HI. This error code will occur when the control board senses an oven temperature above 915F-935F

Once this type of temperatures occur, this will generally weld the relay contacts on the main board. This will damage the board, and it will require you to have it replaced, asap. If these temperatures never reached the sated thresholds, i would advise to Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Check sensor, sensor harness and sensor harness connection at sensor and oven control. Replace the sensor if found to be defective. Check door lock switches for damage, as well.

In most cases, this will be a failed control board. To confirm, simply preform a resistance test on the sensor. The normal ohm readings should be 1100 ohms at room temperature..

We have a double wall oven which is 16 years old. The top oven doesn't heat above 150 and the bottom oven is overheating...the oven said 375 and an oven temperature gauge said 450. Is this fixable or do I...


I have the same issue. Only answer I found was the elements may be burned out. The bottom oven is separate (knobs).Go to GE site and see how to adjust the thermostat (behind a knob).

Error code F7 keeps coming up, what does this mean?


F1 error and beeping. Don't bother getting GE out there. Cost me $90 to learn they don't make the clock. WOuld have been $500+ for the control panel anyway. Better off just buying a new one. Planned obsolescence I guess. I won't buy GE again.

GE JKP27WP1 Built-In Double oven - the start button on the touch pad doesn't work. Everything else works fine. Haven't received an error code.


Try gaining access to the touch pad and, try to free up the start button. if this is unsuccessful, replace the touch pad.
