Kitchen Large Electric Appliances - GE Wall Oven problem

I have a GE JT910 wall-mount convection oven. Lately it has occasionally shown error code F7 - usually can be cleared by turning power off for a couple of minutes.

Apparently this means either a stuck button or defective electronic control board.

Questions I have are: how do I tell if a button is stuck and is there a way to unstick it? How difficult is it to change the control board? If that's possible, then does anyone know the code number for the one I need - I can't find it.

Any help would be much appreciated.

The specific full type number on the oven is JT910COA3CC - if I ignore the "O" in the middle then I can find a JT910CA3CC listed. However, there are two possible parts

PS238531 OVN CNTL
PS246872 PANEL CNTL ASM

Any ideas how I tell which of these to get? Neither one is cheap.

Hello: Graham

What I have is all posted below. You will have to copy and repaste the web site addresses into the browser to get the sites and pages below. Some help can be obtained using the dropdown links in the banner above.

Help and Suggestions:
Read the manufacturers online web site for problem possibilities, solving methods, disassembly, reassembly methods, repair procedures, pictorials, downloadable repair manuals, etc which may be available online.

Search the manufacturers web site for a downloadable version of the owners or service manual. The file will be a pdf file opened with Adobe, which also needs to be downloaded first but worth having once obtained.

Range/Stove/Oven Fault Codes
F1 - Defective touch pad or membrane - Replace touch pad or membrane (this problem is usually the touch pad)
F1 - Watchdog on board - Replace touch pad or clock assembly (also called the ERC)

F1 - Power to element relay energized during time of day display - Wiring harness shorted or change power relay board (PRB)
Note: for double ovens, change second oven board

How to test many brands of Ranges that are flashing a F1 fault code: May have either a bad ERC (clock) or a bad touch pad.

Disconnect power to stove.
Gain access to the back of the clock (electronic range control or ERC).
Unplug the touch pad ribbon connector from the ERC. This will be a flat wire approx. 1 1/2" to 2" wide.
Make sure everything is clear and will not short out when power is turned back on.
Turn power back on to stove.
Watch for the F1 and listen for the beep.
If you get the F1 and beep, replace the ERC.
If after approx. 30 minutes you do NOT get the F1 and hear the beep, replace the touch pad.

Thanks for the reply. It looks like I may have to wait and see if this becomes more severe before I can accurately diagnose which part I need, since right now turning off the power can eliminate the fault code for a day or two. It does seem to be worse when the oven is in use and hot. That sounds more likely to be the electronics rather than the key pad. This may have to come down to a guess and hope for the best.

I've had no luck finding service manuals for the oven, but I have found an exploded diagram of the parts which should help.

Thanks again,
Graham
