F3 Error Code, seeking control board information

My older GE oven has been randomly throwing F3 errors, indicative of an issue with the oven temperature sensor. I've replaced the sensor itself and nothing changed, so that pretty much leaves the control module as the problem from what I've read.

One thing I've seen online is an eBay seller who has a listing for a repair kit for my specific control module number WB27K5140.

Repair Kit for Control Board WB27K5140 GE Hotpoint

Anybody know what it is they're selling in this kit? I've examined the module itself and don't see any indications of failure; no bulging caps or burnt components, so I'm tempted to try the kit. Of course, if I knew what was in it I imagine I could probably source the individual parts myself much cheaper.

This is the board I'm working on.

Alternatively, if anyone knows a specific fix for an intermittent F3 error, I'm all ears.

Update, 4/29/2023

No bites on my original question, perhaps someone knows where I can find a schematic for either the stove or the control board?

Update, 5/1/2023

Have concluded that JSP31WT1WW without the extra zero appears to be exactly the same as my oven which definitely shows JSP31W0T1WW as the model number on the identification plate.

At this point I have to report both good news and bad news. The bad news is that I never did figure out exactly what was wrong with the oven, but the good news is since I opened it up, disconnected and reconnected all the wires, disassembled the control panel and put it back together, I haven't seen the error return.

I have to conclude there was probably some corrosion on one of the wire connectors and the act of unplugging and replugging it was sufficient to make a formerly bad connection into a good one.

Hi Jerry,

Jeez this is a hard one. Have you got any other angles of the board because maybe using the camera will be able to pick up on any burnt areas. Do you also have access to a thermal camera? (Flir or otherwise) That may help figure out where is getting hot and possibly triggering the F3 error. Alternatively you can use your finger as a temperature measuring device as that's never let me personally down when trying to repair anything (This comes from the person that almost fried a board when shorting some pins to ground by using metal pliers and almost killing a laptop).

Let me know if you can get any other angles or can figure out what component seems to be overworking itself.

The board that was pictured is the same board as mine, but isn't a picture of mine. I've since deleted it and substituted a photo of my own board instead. As far as I can tell there's no indication of any component failure visible.

However, this is actually a double-stacked board. There's another board the same size mounted within the frame that holds this board that also has components. It was possible to take a picture of the one side without removing it but to get the other I have to take it out and disassemble it to get to the board.

Mostly it looked like it had the front panel buttons and the alphanumeric display. I can't say whether it has any part in generating the error or not; my gut says probably not, but I don't know.

Can't even find a parts supplier for your model.

Only ones that I can find are these models:

JSP31WT1WW (mini manual part #31-13178)

JSP31WV1WW (mini manual part #31-13178)

JSP31WV2WW (mini manual part #31-13276)

I found the 31-13178 mini manual at least. Couldn't find the other one.

Not a diagram of the board but of the entire range oven. At the bottom of the document it shows that it is applicable to JSP31WT and other models but not JSP31W0T, so hopefully it is also applicable to your model.

It states how to check for an F3 or F4 code which may be of some help.

If the diagram isn't applicable you could try contacting the board manufacturer's tech section and ask them for any information, I suppose ;-)

Ah, the mini manual is sufficient for what I needed to know, which is whether or not there's anything else in the temperature sensor circuit besides the sensor itself. According to the diagram, the two wires going to the sensor connect directly to the circuit board on pins 4 & 6 of the six-pin connector.

I'll try to verify I'm getting a good solid resistance reading under different temperature conditions; it's showing 1100 ohms at room temp and 2650 ohms at cleaning temp, so that should be verifiable.

Not that I expect to find an issue; the entire circuit consists of two wires and a sensor, and the sensor is brand new.

Still could be a faulty crimp on one of the harness wires for the sensor. Check if you can gently pull the wire out of the back of the harness wire connector pin to verify whether it is good (shouldn't come out) or not. Do this at both ends of the 2 wires

@jayeff Last weekend was quite busy so I'm hoping I can get to the oven soon to pull the sensor wires (now that I know which ones they are) and verify that I've got a good solid connection to the sensor. If so, that only leaves the board itself at fault.

BTW, I took your advice and wrote an email last night to the manufacturer of the board asking for information on any known problems with that particular model. Given that someone has put together a kit to repair that specific board, seems like it may be something that's common to that board. We'll see if they get back to me.
