The Lancer 115V 1/3HP Switch Relay is the electromechanical switch responsible for energizing the compressor's start windings. It manages the high inrush current required to launch the refrigeration cycle, ensuring the compressor reaches operating speed quickly before switching to the lower-amperage run circuit.

Problem Solved: Restores cooling functionality to the dispenser. Replaces failing relays with pitted contacts that prevent the compressor from starting or cause it to overheat by staying in the 'start' phase too long.

Symptoms of Failure: Compressor making a repeated 'clicking' noise without starting, the refrigeration deck tripping the breaker, or the motor becoming hot to the touch without chilling the water bath.

Technician’s Note: When a relay fails, always check the start capacitor as well. A weak capacitor puts additional strain on the relay contacts, leading to premature failure. Verify that the water bath level is correct before testing the new relay.
Technical Specifications:
  • Voltage: 115V / 60Hz
  • Load Rating: 1/3 HP Compressor
  • Application: Refrigeration Startup Logic
  • Compatibility: Lancer MMJ4 Series
