AHU Help

My AHU started acting up last week. The blower would stay on constantly until I shut off the circuit breaker. I was able to tap the relay on the side and the unit would shut off normally, but when you cut the power off and back on the AHU would start up and run constantly again. Also at the same time it is doing nothing but blowing out cool air even when the tsat is set on heat and emergency heat. Would the relay cause the system to lose heat as well? The outside unit comes on like normal and the copper line running up to the AHU is hot. Any assistance would be greatly appreciated. Thanks!


P.S. If it is the relay, where can I get a TRANE relay # RLY-02807?

Go to a search for Hvac parts. Try Grainger and Johnstone supply If you can buy from them.
