Rinnai r53 control display out
Just bought a house and the rinnai r53 is not coming on. No control display no hot water.no ignition... nothing.
I have power coming in and the fuses are good. Surge protector is good and transformer is good. But nothing seems to be coming out of the board.
Are there other things I should check before buying a new confuser? And if not, the. Where is a good place to get new boards?
