Question about GE JKP27 Electric Double Oven

Open Question

I have a GE JKP 27 True Temp double oven. The lightbulb on the upper oven went out and I'd like to replace it. I have the cover off, but cannot unscrew the bulb. Is there a trick to it?

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,

SOURCE: my GE true temp has the error code F7 EC. I cannot

Please, don't replace anything, stop letting people rip you off, try this! The insulation in the ribbon cable is poor. The conductors in the cable are crossed. The ribbon cable is actually two ribbons pressed together, and the conductors between the two cables are shorting or becomming crossed. Lift the two cables apart, place a piece of paper between them, fold the edges of the paper over the cable so that it does not slip out, and make sure to shove it all the way down to where it will meet the plastic display panel housing. There, problem solved.

Sometimes you will have to pull the oven out to get access to the connector for the sensor. It could be jammed in the back or the hole is just too small to pull the connector through the wall.

How do I replace the lightbulb. NEFF B1442 series 3 Oven


1. Some glass covers are held on with a wire clip over them. It should be visible.

2. Some have a 'ring' which is screwed to the oven cavity around the light cover. On that design the screws need to be removed from the surrounding retaining ring.

3. On may later model the glass light cover screws into place. Those covers should 9hopefully) be able to be unscrewed the same you you'd remove a jar lid.

JKP56 and JTP56 Differences


Those are not full model numbers, but basically a JKP56 fits a 27 inch cabinet and a JTP56 fits a 30 inch cabinet, so obviously the key panel / control panel would be different. I looked up a couple ERC range controls, and they are also not compatible. Note: usually you will not need both of those parts. The most common of the two is the front panel. (common F1 error code) If this answers your question a "FixYa" rating would be appreciated. Thanks.
