Whirlpool GS475LEMS1 E4 F3 errors

I have a Whirlpool GS475LEMS1 that is creating E4 F3 errors, which according to what I have read indicates a problem with the bottom temperature sensor. I have also received E4 F0 on a couple of occassions which indicates the top temperature sensor. Previous checks of the temp probe resistance when the oven is at room temp have produced 1080 ohms, which appears to be correct.

I also read a suggestion that this could be an intermmitent connection problem, so I have cut the connectors out and hard wired directly. After doing that, the oven was set to 350F and ran for about 30 minutes before producing an E4 F3 error. I checked resistance on the temp probes at the wire connectors where they connect to the control board. Top probe read 1576 ohms, and bottom was 1484.

These errors are inconsistent. Sometimes I can run the oven for an hour or so before it fails, and other times it fails in the first 10 minutes. Is there a way to definitively prove that the control board is the problem? If it is, are these boards available somewhere? My check at Sears PartsDirect shows the part, but they won't let you order it without a service call.

I would appreciate any advice on fixing this and restoring harmony in the kitchen between the oven and my wife

Welcome to the forums.

The harmony maybe slightly out on the horizon. It appears that the control is either not available or is going to be tough to find. Sear's would sell it to you if they had in stock.

The oven control FSP # is 4453608 You can use this part number for a board search.

You bypassed the connectors which is something I usually have people do to eliminate it as a problem. You need to check the connectors on the oven control board..... especially the remote sensor plugs. Check all the pins for loose connections or loose solder on the pc board.

In the event you don't visually find something you can turn to board rebuilding companies. There is one listed below.
