COMMENT: Part numbers 154227808 and 154227805 are open circuit switches. They will not have continuity unless you heat test them to see if they are working. I was given bad information on these two switches when I was testing them when they were cold out of the washer, so I ordered two new switches only to find that they had no continuity either. Then I decided to temperature check my old ones by boiling a pan of water, removing it from the hot burner, and then holding the switch to the side of the pan with the meter probes attached. When the switches heated up, they both activated and then I had continuity. I am not an electrician, but I believe this to be called an open circuit since I had to use heat to activate the switch. There are a number of places on the internet giving incorrect information on these two switches, and I am not happy about the fact that I could not get correct information before I ordered the two new switches to ultimately find out that my old switches were working properly. On the other hand, part number 154290204 thermostat switch IS a closed circuit switch, will and should show continuity when tested cold. I hope this helps someone else along the way who is having the same problem. My problem with the washer is it stops after wash cycle (7 o'clock) and the rinse cycle (10 o'clock) when the high temp wash and rinse cycle option is selected, however the machine cycles thru perfectly when high temp selections are not activated. I have tested temp switch 154290204 and it has continuity, my heating element has continuity, and 154227805 and 154227808 open up when subjected to temperature test. I am still looking for where to go from here! I have seen where replacing the timer (very expensive part) did not solve the exact same problem as I have so, I have been hesitant to experiment with that part. Any other ideas of what I can check? Thanks!

Jim for Model Number FDB750RCC0

ANSWER Jim, The first thing that you want to do is to check the water supply temperature coming into the unit. On high temp wash the water temperature has to rise to 140 degrees as a minimum. If the water temp coming into the unit is too cold then it will not reach desired temperature ant will sit there trying to get to higher temp. You should have no less than 120 degree temp but ideally around 125 to 130 is best.
