Reliable Motor Starting: Precise voltage calibration protects start windings by ensuring the start capacitor is removed from the circuit at exactly 75-80% of full motor speed

What are the signs of a failing motor control module

preventing high-head pressure trips and extending the service life of the compressor

The interface module works in conjunction with the main integrated furnace control to ensure the inducer motor reaches the required RPM before allowing the ignition sequence to proceed

Class RK5 fuses like the S1-FRSR15 provide superior current-limiting features

Lochinvar & A.O. Smith 100274734 Flue Sensor 324846-701 Reliable Motor Starting: Precise voltageThe Lochinvar & A. O. Smith 100274734 Flue Sensor is a critical safety component designed for high efficiency condensing boilers and water heaters. This exhaust temperature sensor monitors the heat levels within the venting system to prevent heat exchanger damage and plastic vent meltdown. Also identified by part number TST2013, this NTC thermistor provides the control board with precise resistance readings, ensuring the unit modulates or shuts down
