I've got a 4-5 year old hot water heater that has been cutting out about once a day for 3 or 4 days now. Once I hit the re-set button it works until sometime at night, when it seems to be tripping. Any ideas what's wrong and what I can do to fix it?
Mark - hi, it does sound like the thermostat's gone bad. I'm not aware of an easy way to test it, but I recently replaced the upper and lower thermostats on my mother-in-law's water heater. I paid about $26 for both at a plumbing supply store in Waldorf, MD. She was having the same problem, although not as frequently (it only tripped once a week unless she had extra house guests and put a big load on the water heater). The thermostats haven't tripped for over 4 months now. Good luck! Jim D/Heathsville, VA
there is no way to tell if it is the upper or lowwer stat, one of them is sticking on and causing it to trip, (im asuming that you are reseting at the thermostat and not the breaker) you need to replace both, they should run around $15.00 ec
