John, You said: "...You can replace the circuit breaker and it will do it again when on the fourth speed. I wouldn't advise uping the current on the circuit breaker, just don't run the fans on 4th speed...." The factory installed 25 amp circuit breaker for the blower circuit is under rated. The 30 Amp upgrade( part #106085G) is a 100% successful fix for this problem. This circuit has no trouble handling the higher current breaker upgrade, once this component is replaced there should be no further problems with this circuit.
