I am working on a Hotpoint gas oven where the panel keeps giving an error code of "F4" (open sensor?). I looked in the GE manuals but didn't find this particular model. Turn the oven on bake, select temp and hit start... it will start the preheat and then go to "F4" and won't do anything at all. I disconnected the sensor and checked ohms... it read approx. 1000 ohms which seems in range I believe. I would appreciate your help.

Thanks

The sensor is reading low.
It should be 1050-1150 ohms.
It could also be a bad wire connection.

Number 43

GE / Hotpoint / RCA
Oven Fault Codes
Display Condition Remedy
F0 & F1 Failed Thermistor Control Replace ERC
F2 Oven Temp Exceeds 590 with unlocked door High resistance in Sensor, likely a bad sensor
F3 Open Sensor circuit Open (blown) sensor fuse or bad Sensor
F4 Shorted wire or Sensor locate short and correct it
F7-A Function pad button stuck Clean and unstick
F7-B Bad Clock Replace Clock
F8 Electrical component failure Replace ERC
F9 Program with door circuit Check wiring



Note: this video shows how to check a sensor, even though it is not a GE they are all basically the same deal. If that sensor quick connect is greasy or corroded just by passing it or cutting it out will sometimes fix the problem.

I decided to take a look at the control board (which I should have done to begin with). While I was taking the screws out of the front panel and lifting the frame to get to the board, roaches start coming out from inside the panel. When I got to the point where I could see the board, I noticed a burnt spot on the board. I figured roaches got inside and shorted out the board. I replaced the board and told the customer what I thought probably caused the problem and that he should take measures to try to prevent this problem again. The oven is working fine now. Thanks for your help.
