I just bought a brand new Pentair master temp 250 after my pool guy couldn’t figure out why my old heater temperature kept spiking. I purchased a new heater and then the same problem persisted. my pool heater would fire up then start to heat for a few seconds then the temperature would spike up over 100 which would shut the heater off so the heater would only heat for a couple of seconds before shutting off and then the cycle would repeat over and over.
I ended up replacing my two year old pump with a brand new pentair pump so now I have a new master temp heater and brand new pump. I just fired it up today and the heater is doing the exact same thing. Pool guy thought it was a glow issue but now I have all new equipment. Help!
