Dishwasher stops , after it sets awhile it will start again. Could this be the high limit thermostat.
The high limit thermostat would not cause the unit to shut down and not operate. This thermostat is for the heating portion and will only turn the heater off it is getting too hot. As for the issue that you are having you will want to check to make sure that there is not anything in the circulation pump that would cause a drag on the motor of the unit. If this checks ok then it sounds like the control board would be the issue.
Is the high limit thermostat normally open or normally closed? (9751984) What is its' purpose?
Answer Hello J.T.,
The high limit thermostat will be closed, (reads continuity with no resistance), until it gets hot enough to open. The purpose of the high limit is to prevent the temperature from getting high enough to cause a fire or unsafe condition.
