I have a shop heater with a 1/3 hp capacitor start, induction motor driving the fan. Intermittently, the fan motor speeds up significantly for several seconds (15-60 sec) then slows to normal operating speed. The manufacturer suggested changing the capacitor which made no sense, but I did it to no avail. Could this possibly be caused by the centrifugal switch intermittently reconnecting the start winding?
