Mastertemp 400,000

740 viewsService

I have a Pentair MasterTemp 4000. Looks like the heater keeps restarting. It will start for a few minutes & then I hear a sound & it’s restart again. I’m thinking about checking the thermal regulator, but do you have any advice? There are no error codes. The heater light comes on & then it’ll blink.
