Is the inducer motor coming on only or is there burner ignition and then shut down? Newer pool heaters have a pressure switch for the gas pressure and when a pool heater burner comes on that intial drop in pressure can cause control to time out. Make sure your gas line is large enough for btu rating. Also your gas meter may be undersized for your btu load. The flame rectification sensor is also possibly the problem like the person above stated but i would not call it until you have verified the sensor is working. Dust or debris can cause the sensor to false read.

Pentair Pool Heating Rapidly Increases Temp on Panel then shuts off.


Check the Thermal Reg in the header and also make sure you have adequate water flow thru the heater, make sure your filters are clean and there are no external by-pass valves open.
If you remove the Thermal Reg in the header and the heaters seems to run fine the replace with a new one.

Pentair Minimax has worked correctly for 5 years. Now is comes on and the heater starts up for maybe 30 seconds and shuts off for a minute or two. It cycles like this for a really long time... a couple...


Usually this means that the flue temperature sensor indicates too high a temperature. this is usually caused by too low water flow through the heater and therefore both the water and the flue temperature is too hot. You should check all the baskets, the pump impeller, the filter and any return devices to make sure water can flow at full rate. It is unlikely but maybe the flue temperature or control board is defective.If all else fails you may be able to call the Pentair technical support line to help diagnose the problem. I hop this helps.

I have a Pentair 40,000 BTU pool and spa heater. It comes on and then shuts off in about a minute with an error code appearing in the readout. The error code is E05. What does this mean?


The heater is trying to light but cannot. Either the igniter is broken or you are not getting any gas to the igniter. Check to make sure your gas valves are on.

My mastertemp heater has a error 5 reading. Heater starts, then it shuts down after about 10-20 seconds.


This sounds like the flame rectifier (flame sensor) Below is a link to the manual to trace the part and also to get the part number.
