I was asked to do a few things at a Church. It was mainly just a quick look at adding some lights and replacing a switch. After I looked at the things and was about to leave, the guy asked if when I came to do the work if I could check their baptistry to see why the heater for the tub kept tripping. I asked if the GFCI was tripping and he said yes. So I started to check the GFCI breaker to see if it held with no load on it. It stayed on and I told him if it was tripping there was something wrong with the heater. He said that it was not the breaker that tripped but they had to hit the reset button on the heater box.
I didn't have time to check anything on it but said I would look into it when I did the other jobs.
My question is, what would cause the heater to have to be reset and not trip the GFCI breaker? He said that when they use the baptistry, they keep the thermostat set to "high".
What is the heater unit sensing that causes it to shut off and need resetting? I know little to nothing about how they work, but I'm guessing it's a high temperature shut-off. Maybe the thermostat is sticking and causing it to overheat.
I just need to know what to look for when I check it. If anyone can help with this, I would appreciate it.
