Browning AK66H Sheave 318973-401 Vibration Dampening: Secures internal components

Vibration Dampening: Secures internal components to reduce mechanical noise and prevent hardware fatigue during operation

Replacing a compromised limit control ensures system reliability and prevents nuisance tripping caused by weakened internal thermal discs or high-resistance electrical connections frequently seen in aging residential HVAC systems

Proper alignment and gap settings are vital to maintaining the microamp signal necessary for the control board to verify combustion

Designed as a non-spring return direct coupled actuator

preventing erratic system behavior caused by low-voltage drops
