Question about Pentair Minimax NT Heater

1 Answer

I have a 2003 400K btu Pentair MiniMax NT pool heater that refuses to ignite. Only light showing lit on the unit is the green ''power'' light. I've turned off and turned back on the natural gas control in the unit as per instructions...no effect. Any suggestions as to where I should start to pinpoint the culprit would be greatly appreciated! Thanks!

New ignitor..still won't light


Clean out the pilot assemby or replace it. It is probably blocked by rust and/or spiders and is not letting enough gas (if any) through.

My pool heater will not start. The power light is off and the pressure sw is lit.


You must turn on the pump and let water circulate through the pool and the heater before you turn on the heater otherwise you will ruin the heater
