Barks507 Posted August 24, 2014 Report Share Posted August 24, 2014 I keep getting FL2 fault code. Changed igniter and cleaned flame sensor. I was poking around the other day and wiggled the wires that go into the gas valve. All the power cut out on heater? Tried resetting via breaker. No LCD or anything. Any ideas?

ps0303 Posted August 25, 2014 Report Share Posted August 25, 2014 Sounds like maybe you blew the transformer in the heater. Your wiring from the breaker goes to the transformer and then the transformer feeds the unit @ 24V Quote Link to comment Share on other sites More sharing options...
