Our licensed technicians have performed a heater Carrier repair in Napa, California. The customer told Fuse that the heater stopped working. When they tried to turn it on, it would either not turn on at all or switch for 3-4 seconds and then shut down again. The problem with the heater was that the wires were disconnecting. Fuse techs fixed the wiring and after that the heater started turning on normally again.
