Hi
I have a GE wall oven model #JTP86SH4SS which normally works fine, but when I try to use self clean mode; after a while it turns off and does not complete the self clean cycle. I am not sure which part to replace. This is a microwave/oven combo built into wall. Any help is appreciated, thank you.

Just an update. It actually shows error f9 after running about 45 minutes on self clean. Fan is running fine as well. After 45 minutes, it would show the error and will lock the door until cooling down and unlocking it.

Hi,

F9=Cooling fan stalls while oven above 650°F—open thermal switch in yellow or blue leads.
Cooling fan or airflow to control area.

So it looks like the cooling fan is stalling. Do you hear the cooling fan running the whole time?

I'm attaching your service manual below, look on page 35 where it says this:
The other thermal switch is for sensing cooling fan operation during non-self clean modes only (located in unlock switch side of door lock motor circuit). It opens between 176 °F (80 °C) and 212 °F (100 °C) and closes between 149 °F (65 °C)
and 185 °F (85 °C), depending on model.
If the thermal switch opens in any mode of operation, the control will go to -F9- failure code. When this condition exists, check the fan operation (look for obstructions) and inspect oven installation (make sure grill areas are not blocked), oven
insulation, and lock circuit.

Here's the console cooling fan motor assembly for your model:

Thank you for your reply. So hopefully replacing this fan motor assembly will fix this issue. I also read online somewhere that it can also be the cooling fan but the one located inaide control panel which is part # WB26X10026. Could that fan also cause this error or will it have to be the one you mentioned which is located in between oven and microwave to the back center...? Thanks for your help.

WB26X10026 is your microwave fan, that wouldn't cause the F9.

Its the fan I posted in post #3.
