GE temperature sensor came loose

Hi the brackets that hold my temp sensors in place popped free and I just need to know what the position of the sensors should be si I can clamp them back in place. the model is an older GE gas range. thanks

Really no difference how it hangs, so long as it doesnt touch the oven walls, and is up high enough so you dont hit it withthe pans/food you put in

How does one replace the oven temp sensor?


Pretty easy, usually located at rear top of oven, one screw holds bracket, so remove, then you will see wire, pull it out to access connector, replace with new one, plug back in and replace bracket. My GE was easy fix and sensors are low cost.

JS968SF4SS model gives 'F2' error. Possible


F-2 usually oven sensor shorted or bad. Replace oven sensor an you should be good to go. Hope this helps.

I have a GE model JKP13 and it keeps going off, beeping and flashing f2 or f3


HI, the oven has experienced a very high temp due to a failed sensor. Check sensor harness and harness connection between oven sensor and oven control. Replace the oven temperature sensor (RTD) if wiring is ok.

Next. Look for a high resistance connection or any other cause of high resistance in the oven temperature sensor circuit. Look for welded relay contacts as well on the control and sensor. replace, both the control and temp sensor if weld spots are visible.

Oven flashes F2 and beeps in the middle of baking or broiling something. Our oven is all electric and recently whenever we start to broil or bake something, after a little while it will shut off and the...


HI. an F-2 during a baking cycle is the result of an out of control oven temp that has reached Temperatures above 615F-630F

If this actual over temperature condition occurred, Look for welded relay contacts on bake or broil relays. If this happens, replace oven control (also called clock or ERC).

If no over temperature condition occurred, 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 sensor if found defective.

Remember: Oven control (ERC) measures resistance of sensor circuit , not actual oven temperature.

Preheat takes forever


http://www.applianceaid.com/nuker.html
click the link  Oven temp sensors sense the temperature is the oven cavity and the temp sensor changes resistance, this change in ohm resistance tells the oven control what temperature the oven cavity at and tells the control to shut off the element or turn it back on. The most common temp sensors used today ( *not all ) are approx 1000-1100 ohm resistance at room temperature ( 70�F )
Some ohm readings and there temperature:
Degrees F    -   Resistance
            100 - 1143 ohms
             200 - 1350 ohms
             300 - 1553 ohms
             350 - 1654 ohms
             400 - 1753 ohms
            500 - 1949 ohms

GE Oven displaying both F2 and F3 error codes; bad ERC or temp sensor?


F3 is Open oven temperature sensor circuit.
F4 Shorted oven temperature sensor circuit .
F7 Component failure.

To fix this you need to read oven temperature sensor circuit at oven temperature sensor ( approx 1000 ohms at room temp); check for cut or pinched wire or loss of contact, if wirings are ok, then replace the probe.

E1 f2 error


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

F2
Note: Also see fan thermal switches - Indicates that oven is over temperature in one of the following modes within either a cooking or clean mode of operation.
· Control senses oven temperature above 650 degrees F with the door circuit in the unlock mode.
· Control senses oven temperature above 935 degrees F with the door in the locked mode.
· Stalled cooling fan or airflow problem.

· Look for welded relay contacts. (Heating elements on in off mode).
· Look for open thermal switch in lock motor circuit. Switch is normally closed and will open if area overheats due to fan not operating. Look for cause - fan thermal switch not closing, fan stalled, etc.
· Look for high resistance in the oven temperature sensor circuit due to high contact resistance (poor terminal crimp, deformed terminals, loose connection) or intermittent solder joint on control or intermittent oven temperature sensor.

Good Luck

GE self cleaning radiant oven - model JB578GP


I went out to my circuit breakers and turned the circuit off, let the oven cool, and powered it back up after about 2 hours. Fine now.

GE JKP27 F2 error


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......,
