or can no longer satisfy the millivolt requirements of the thermocouple despite proper gas pressure

this ASME Section IV certified safety valve is factory-set at 75 PSI to ensure reliable overpressure protection

High Thermal Range: Designed to handle a maximum fluid temperature of 250°F

Maxitrol TS144 Sensor 30067439-890 always verify the supply voltageThe Maxitrol TS144 is a precision engineered discharge air temperature sensor designed specifically for integration with Selectra modulation systems. This dual range thermistor serves as the primary feedback loop for the gas valve, ensuring optimal burner adjustment based on real time discharge temperatures. Functioning within a 40F to 80F minimum and 80F to 140F maximum range, it provides the critical data required for Selectra air temperature
