Sometimes a motor goes bad,creating excessive draw and overloading the circuitry.
Switch overheating and circuit opens. If its not the motor, i bet you will find a hot or melted connector. Infra-red thermometer would come in handy.
Cool. I’ll try that too. Might have to make a quick trip to the tool store (which I never mind) haha. Just point the thermometer at the wire to get a reading?
