What to do if the HASE Gas Heater pilot won't stay lit?
- Cchristy25Aug 21, 2025
If the pilot light on your HASE Gas Heater won't stay lit, begin by checking the gas pressure to ensure it's neither too low nor too high for the gas being used. Also, make sure that the thermocouple connection at the gas valve is tight. Faulty connections could also be the reason. To check this, measure the voltage between the valve body and the solder connection on the rear of the valve (where the blue wire connects); it should be no less than 7 mV. Lastly, a dirty or plugged pilot could be preventing the pilot from staying lit, so you may need to clean or replace the pilot assembly.
