Question about Pentair Minimax NT Heater
Unit is 4 years old. Pilot light is lit. Both stats will work by change in resistance. I have voltage thru the series of water sensors in the header. But the main burners will not ignite.
Could it be the pilot sensor or a stuck gas valve? Thanks
If you read Ohms across the TH circuit with the thermostat(s) turned up and the switch in the on position with the pump running you should have about 1.0 Ohms. Anything higher than 2-3 Ohms and you have too high a resistance reading and will need to find the bad part/connenction. If you have about an Ohm and the burners are not lighting be sure you have enough voltage off the generator. With no call for heat it should read around 500mV. Once you turn everything on it should drop to about 300mV.
If all these reading are correct try striking the gas line near the valve. The solenoid may be sticking. If it frees up you may get more use from it. If not, the valve needs to be replaced.
