Furnace Heater doesn’t heat – Furnace heater Repair in San Jose, California
Customer’s had an issue with furnace. Furnace didn’t heat after thermostat turned on. After diagnostic I did decide to replace pressure switch becuase it’s didn’t work well. After two weeks customer called me back and said that it’s stop working again. In this time – gas didn’t come to burners while igniter igniting. I did check incoming voltage to gas valve while start and found that just 9VAC coming to there. After few hits to relays on control board – furnace started working. I decided to replace control board ces0110057-00 to ICM281. After replacing control board – everything started working perfect.
