I recieved the F24 error code (Water Temp switch). From research online and calling whirlpool, it was assumed that I needed a new control panel. I was told by whirlpool that this "switch" was not seperate, but was in the "mother board". I ordered one, installed it, got two wash cycles to run, and the F24 code is back. Is their a seperate switch? What does the switch labeled AP4340286 do?
Ok, Whirlpool is right, but that error code probably refers to the water temp sensor, this part here
The part you referenced is the water level switch and is probably not a part of your problem.
Inside the lower service panel should be tech notes that will help you. Sorry Whirlpool may have steered you wrong.
