GE JTP48 Electric Double Oven Questions & Answers
The top oven beeps and an F1 is displayed in red
Here is some wisdom for understanding F1 fault codes.
In some models, there are subcodes that make diagnosis even easier.
Here's a simple explanation of what's going on and how to troubleshoot:
The F1 code indicates that:
a. The electronic range control (ERC) is sensing heat in the oven when in a time-of-day (i.e., not cooking) mode.
b. The ERC is receiving information to run multiple heat functions simultaneously.
Although different components (depending upon the model) could generate the code, simple and straightforward testing using your ohm meter is all you gotta do to test for it.
1. Check the oven temperature sensor. The oven sensor has to be within spec or it will cause the F1 code.
As an example of being out-of-spec, the ERC will generate an F1 fault code when the sensor shows 1650 ohms during a time-of-day mode.
This is equivalent to 350°F in the oven.
The resistance isn't high enough to generate an F2 code (runaway temp) or an F3 or F4 code (shorted/open sensor circuit).
The ERC monitors the sensor circuit after a heat cycle and expects the resistance to drop back to 1050-1100 ohms.
The fault code is generated when this doesn't happen. Checking the sensor circuit means also checking the harness,
harness connections and the sensor itself.
2. If the oven sensor circuit checks okay, then turn your inquisitive eyeballs to the touchpad.
If the range has a separate touchpad/keyboard, the keypad may have moisture that is shorting several circuits simultaneously.
If the F1 code is given immediately (instead of during or after a heat cycle),
remove the ribbon connector from the touchpad to the ERC after clearing the F1 code. If the F1 code does not return in five minutes,
then cast a suspicious gaze upon the touchpad/keyboard. Shorts may be caused by using an ammonia-based glass cleaner.
The touchpad surface will absorb ammonia-based cleaners that are sprayed directly on the glass surface. When heat is applied,
the surface material can break down causing shorts.
If you're gonna use ammonia-based cleaners on your control panel, then you should spray it on the rag and then wipe the touchpanel
-don't spray directly onto the surface of the touchpad.
3. On Amana ranges with a rotary temperature dial, be sure that the knob is in the OFF position when performing tests.
4. If these tests all check good, then replace the ERC.

GE JTP48 console wouldn't display after spark
if the console is not displaying then most likely due to the spark you have shorted the LED inside the electronic control and would have to replace the electronic control on the unit and there are 27 units with that model number. If you have the full model number I can provide schematics of the unit and the part that you would have to replace. If you have any further questions message me back I await your reply Thanks Rick

Start and clear buttons will not work on both
Turn off the power to the unit for a few minutes, and then turn the power back on; this will reset the controller. If this solution does not work, you may need a new control board

GE electric double oven
Colin, the TCO is located on the back of the oven. It will open L2 to the heating element in the event it is open. If this TC0 opens it will not show any error codes. This is for the 27 inch wall oven models only. Catriver...post back.

Not finding what you are looking for?
oven is not heating then you probably have a bad heating lelement in your oven. This is not that hard to fix yourself...
