Product review (5 stars): Great upgraded Relay!!
worked perfectly in a American Standard(Trane) air handler for a heat pump. Symptom was that the blower would occasionally not turn on while the AC was running and cause everything to freeze up. Was difficult catching it in a fail state but once I did I could verify with a multimeter that the relay was not sending power to the blower motor. Very easy to switch out. All the wiring on mine had the same configuration but this is an updated Relay so pay attention to wire colors as well as contact labels. Directions are included for installing.
