Does anybody know what the linc system is monitoring for electrical errors? I have a blower error. If i hit button the blower goes on for 5 sec and then off. Display shows an error. I check the incoming voltage to blower and its fine. I isolate the blower and direct connect to battery and it works fine. The only thing i can figure is there must be a pressure switch in air duct that is defective so the linc system shuts down the blower?
