Question about Pentair Mastertemp Pool & Spa Heater Dual Electronic Ignition 400,000 Btu Lonox Propane 460737
Your temp sensor has gone bad. It is a small tube that slides into the water manifold with two wires comming from it. Follow these to the control board and then unplug them. Now just get a new one and replace. This should fix the problem. Good luck.
