Appliance:
GE Electric Range, Model #JBP78AB1AA
Problem:
Oven temperature fluctuates; When you set the oven temperature up to 300
degrees the oven works. If you set it higher than 300 degrees the
temperature does not reach the set temperature.
Solution:
If you select bake, most often what will happen is the control
board (part #WB50T10043) will
cycle both the bake
and broil element on at
startup to help preheat the oven in a faster amount of time. After that
it's normally maintained by the lower unit or the one on the oven floor which
is the bake
element (part #WB44T10011).
So, your temperature problem seems to be that your oven is only preheating. The oven normally uses just the bake element (part #WB44T10011) to maintain the temperature, that's why you're getting the temperature swings and it won't get up to more than 300 degrees. Most often, the bake element is the culprit causing this GE range repair problem.
If the bake element (part #WB44T10011) is working well, then you probably have a problem with the controls. Most GE ranges have a relay center on the main control board (part #WB50T10043) telling them to turn the unit on and off and it is possible that that relay is shot. Also, it could be that the wiring from the board to the element itself is burnt or has a break in it. On newer units, this is not common, but on older units sometimes heat conditions cause burns.

1997 GE Electric Range, Model JBP78AB1AA
Problem:
Oven temperature
fluctuates. It will indicate that it's at the proper temperature, but a
thermostat shows that it's not near the proper temperature.
Solution:
When bake is selected
the control board (part # WB50T10043) will cycle both
the bake and broil element on at startup to help preheat the oven in a speedier
amount of time. After that it's normally maintained by the lower element,
which is the bake element (part # WB44T10011). When you set it
to broil see if the broil element (part # WB44T10009) and the bake
element are both glowing bright red. If the bake element is not getting hot,
that's where you're getting your temperature problem. Most often, the bake
element is the culprit causing that.
Use a multimeter (part #DM10T) to check it for continuity.
If the bake element is passing the continuity test but not heating then you probably have a problem in the controls. There is usually a relay center on the main control board (part # WB50T10043) and it tells the oven to turn the unit on and off. It's possible that the relay is bad, the wiring from the board to the element itself is burned out or you have a break in it.
It could also be the control board itself. A lot of times if you take it out you can actually see on the back side that the relay is burnt. The other thing you want to check is the oven sensor (part # WB23T10002) and those normally read about 1000-1100 ohms at room temperature. If it's broiling okay the sensor is probably not bad, but check it just to make sure. If not, then it could be the main control board (part # WB50T10043) or the relay board depending on which one you have in your unit.
Appliance:
2005 GE Profile Double Oven, Model JT955
Problem:
About 10 minutes into heating cycle F2 error code appears
Solution:
The F2 error code could means the clock control senses the oven temperature is
above 590 degrees. This usually means the oven either has a bad sensor (part #WB23T10015) or it could mean a
bad control board.
