Question about Pentair Mastertemp Heater
Heater comes on but stops heating after about 3 minutes then service heater light comes on. Heater stops heating for a few minutes then comes back on then after 3 minutes or so it stops heating again. Have turned it off rather than let it turn on and off contunally.

Sounds like the controller is the problem. This is the circuit board that has the display and controls on it. You can swing that panel open and try tapping on the white plastic cover the controller is under that. This might get the fan relay to release but you will have to replace the controller it will stick again

try cycling the power to the heater itself. Check for damage (pack rats, etc..). It sounds like you may have had a direct short. It could be a board problem or a transformer problem. If you're still getting the service heater light, check to see if any diagnostic LED is illuminated behind the board.

This is an ignition flame falure code. Could be you don't have gas getting to the pilot, no spark to ignite the pilot or your ignition is not reading the flame. Sorry to say but it's probally time to get the pool guy out to look at it. Good luck.

SOURCE: heater cycles on / off
This could be a water flo problem. you need to chech to be sure your by-pass valve is closed down enough to force water threw heater, There is a internal by-pass that could be a problem also, or a bad pressure switch. If the by-pass isn't the problem then you should check these also.
