    Changing heater size

    I have a 9000 gallon small pool that had a MasterTemp 400 heater installed. The basket and coils rusted out and the replacement parts are not worth investing in a 9 year old heater. I was thinking about a new MasterTemp 250 bc it is a bit less expensive and the hookups should be easy except for...

    Brand new MasterTemp 125 not igniting

    I’ve had a brand new Pentair Mastertemp 125 installed. The board comes on, then I hear the blower. It tries to light several times then sometimes it will eventually turn the service heater light on. While trying to light several times, I will smell some gas. I’ve tried to bleed the line from...

    Pentair MasterTemp 250 runs for couple minutes then triggers Service Heater light

    It starts fine, runs for 2-3 minutes then triggers the Service Heater. I took the front panel off to see the LEDs on the board and I see nothing that is on. What would tigger the Service light if no LEDs are triggered? If I turn it off and turn it back on, it will run again for the 2-3...
