I have just moved to a house with a Pentair MiniMax NT pool heater. When I click on the heater I get all the lights on, even the flame LED comes on for a short time, and then turns off. Then the service light comes on. The blower continues to run, but no heat comes out.
I am a mechanic, and I have read and seen some videos of how you can take the heater apart. I am willing to tear into it, but would like to know if anyone has any tips or tricks. I am assuming the heater has been fully neglected for years, it looks pretty rough.
I got a chance to open up the heater during the day today and looked inside. It looks like a furry little friend might be taking refuge in our heater box. Here are some photos of the setup.
