My water heater has a blower attachment that kicks on when the water heater begins to heat water and shuts off when it is done. I'm no water heater expert, but I believe that these actions are related to the thermostat.
Recently, I've noticed the blower remains on well after the water heater turns off. Meaning, the blower motor is running, but the only flame burning is the pilot light. In order to shut off the blower, I have to unplug the water heater, turn the thermostat up until it clicks on, plug in the water heater (which causes everything to fire up) then finally turn the thermostat back down to normal (which causes everything to shut off as usually the water is at the desired temperature).
Can somebody help he understand what is going on here and how I can keep it from happening again?
Unfortunately, my water heater is wrapped in an insulated cover...so I can't see what brand it is...and I'm reluctant to pull the cover off.
However, I did find a plate on it that says:
Manufactured by State Industries Inc Model PR650NOVT Serial Number 001200512
