An apparatus for controlling the operation of a refrigeration system having a compressor, a defrost timer that provides an operating power supply, a solenoid valve, and a thermostat includes a relay switch and a delay timer. The relay switch is coupled in series between the defrost timer and the thermostat, and it is configured to electrically disconnect an operating power supply from the thermostat for a predetermined time period regulated by the delay timer. The solenoid valve closes when the relay switch is in the opened state and the compressor remains functional during the predetermined time period. |
