There was evidently a power surge. Upon arrival I found burnt wires coming from the main system contactor. The blower would not operate. I told the customer I would need to repair these before I could test the unit. Once the burnt wires were replaced the blower was the only thing that worked. The zone board is corrupt as well as the 2 boards in the unit that operate the compressors. I tried to get the unit to run on auxiliary heat but the zone board despite having inputs from each Tstat would never energize the auxiliary heat contacts. I manually jumped them out and the auxiliary heat did operate. I could not leave it jumped out because it would never turn off. I made an estimate to replace the main zone board and the two boards that operate the 2 compressors. I took pictures of the parts. Customer needs to contact insurance before approval of the repairs. Customer paid for the burnt wires to be fixed. I would suspect a surge from a storm damaged the electronics.
