Hello. I had all of my pool equipment replaced at the end of the season when we had the pool surface refinished and re-tiled. The pool was built in 1986. We now have a 1.5hp variable speed pump and a Rheem gas heater. The heater was actually replaced about 2.5 yrs ago. When the new pump was installed we had to upgrade the electrical as well. An electrician put in a dedicated box and moved our pool light breaker and installed a GFCI double 20amp breaker for the pump and heater in it's own box. The pool has been open for the season for a few weeks. Everything was running fine until this week. For the first time ever we went out and found no power to the pump/heater. The breaker had tripped. I turned it back on and everything started back up but the heater was making a horrible noise like it had souls trapped inside it. I called the local pool company and was told to try adjusting the speed of the pump. I cleaned the filter, etc and increased the speed on the pump and the sound went away. The breaker has tripped at least 3 more times over the next several days. The longest it has stayed on is about 24 hours. I now have the heater off but it has only been around 12 hours, and the pump is still running fine. Any idea what could be causing the breaker to trip? I'm not sure if I should call the electrician or have the heater serviced or both.
