Customer Question

My 40 gallon B W power vent gas water heater runs when I repower, heats water tank than shuts off, does not restart. I follow directions, unplug power, turn gas switch to off, turn down thermostat & than turn gas switch back on, turn thermostat back up & replug, usually it starts up again, reheats tank & shuts off & doesn't restart on own
JA: How long has this been going on? And how severe is the problem?
Customer: About Friday it stopped running, severity is that my daughter lives in the house & I don't want her restarting it like I was Service call is about $ 125.00
JA: Do you plan on doing the work yourself?
Customer: I would like to, but I probably should have a professional check it, my brother says it may be a thermo-coupling what could it be ?
JA: Anything else we should know to help you best?
Customer: Trying to decide if I should spend money for service & repair or buy a new heater the burner may be slightly rusty, like I said it fires back up when I restart the system

Welcome to Just Answer, my name is ***** ***** I will do my best to help you with your issue. If my initial response doesn’t answer your question then let me know and we can continue our conversation.

No thermocouple in a power vented unit. Sounds like possibly a dirty flame sensor. Could also be rust flakes grounding out the flame sensor.
