Sometimes my hot water heater does not restart. If I turn off the coach switch and turn on again it will restart. Anyone have an idea of what the problem may be? (Suburban heater 10 gal.)
Remove all the electrical connects and burnish the contacts with a lead pencil eraser. Reconnect and pull off a couple of times before leaving seated. Blow out or vacuum any soot or debris. If this doesn't correct it, it probably needs a new circuit board.
