I have a Frigidaire dishwasher and it gets stuck before going to dry cycle. I have tried turning off the heated wash, heated rinse and heated dry and it finishes the wash cycle. Does this mean that the this is the thermostat? I have looked at a list of the parts and confused which thermostat and where it is located since there appears to be three, one on the tub, resettable thermostat p/n 154290204, and two on the door, temp assure thermostat p/n 154227805 and thermostat 154227808. Any help will be appreciated. Looking at the wiring diagram, it looks like one for the heating element, one for the high temp wash and one for the high temp rinse. Is this correct, and which one is which (part nuber wise). Any help would be greatly appreciated.
ANSWER Hello Geoff,
You would want to check the continuity of the High limit thermostat 154290204 which is located on under the left side of tub. If it is reading open then you would need to replace the high limit thermostat. The hi limit thermostat should only be open in circumstances of the temperature rising above 200 degrees. It will reset at 100 degrees. There are 2 other thermostats on the unit. The Boost rinse thermostat and the Boost wash thermostat. These two thermostats are open thermostats until they reach temp. The Boost wash thermostat 154227805 will close at 117 plus or minus 5 degrees. The Boost rinse thermostat 154227808 will close at 122 degrees. To test to make sure that they are working properly you would want to put into hot water that is above 125 degrees and check continuity to make sure that they close. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
