Today we came out due to system not heating. Upon arrival, customer said system would not heat, but the ac would work. System is a Goodman package unit. When we approached the unit, I could hear a buzzing sound. This buzzing sound is coming from the inducer draft motor. The motor itself was stuck closed and after spinning it manually, system kicked on and produced heat. However, motor would not stay on and the moment it quit working, heat no longer worked. The inducer draft motor has to be replaced. As of now, the part supply house is closed and I will call 1st thing tomorrow morning to see if and when the part is available. Once I know something, I will call back to inform them when I can come back to replace inducer. It was a pleasure meeting you today and I’ll give you a call tomorrow morning with an update.
