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.)
Probably your thermostat. When the primary thermostat fails and the heater shuts off on the Emergency Cut Off (ECO) thermostat the circuit board locks out. You reset the circuit board when you turn it off and back on. Cheap fix. Both thermostats, under $20.00 Easy test. See if your water seems exceptionally hot at the end of the heating cycle. Primary stat 140º. ECO stat 180º.
