Question

A refrigeration system low pressure cut-out switch has an adjustment advisory that states that the cut-out is the cut-in minus the differential. Currently the compressor starts a few moments after the thermostatically controlled box solenoid re-opens and begins feeding the evaporator meaning the cut- in value is properly set. As the box solenoid closes when the minimum desired box temperature is reached, the compressor stops almost instantly. As a result, the compressor short-cycles a few times before the pump-down is complete. What must be done to correct this?

Accepted Answer

the differential adjustment must be adjusted to lower the cut-out
