Always verify the root cause of the thermal trip—such as a failing blower motor or restricted ductwork—prior to installation to ensure reliable system operation and to avoid repeated component failure

the 52W29 is the standard service part for most G40

Nordyne 626407R Limit Switch range required by the furnaceThe Nordyne 626407R Limit Switch is a critical OEM safety component engineered for precision temperature monitoring in Nordyne, Intertherm, and Miller gas and electric furnaces. As a 2 pole, automatic reset L145 40 limit switch, it is calibrated to open the circuit when the internal plenum temperature reaches its 145? F high limit set point and automatically closes when the temperature drops to the 105? F reset threshold. This high limit control is
