Question about Pentair MINIMAX NT TSI IGNITER
I HAVE A PENTAIR MINI MAX NT 400K POOL HEATER. THE FAN COMES ON AND THE GAS VALVE CLICKS ON BUT DOES NOT IGNITE. SOME TIMES I SMELL GAS AND OCCASIONALLY IT WILL IGNITE BUT ONLY STAYS LIT ABOUT 2 SECONDS. AFTER 4-5 TIMES I GET A F5 FAULT INDICATOR LIGHT. THE IGNITOR IS GLOWING BUT NOW ITS NOT IGNITING AT ALL.
Could be dirty heater you have to clean the runners and the smole nozzles that are in the manifold below the gas valve it's like a 9/16 size you pull them off and check make sure they are clear through, sometimes little spiderwebs build up inside them. if it's all clean, then it could be you flame rectifier/ aka: flame sensing rod, that tells the htr that there is fire so it keeps running. Let me know what happened.
