Fan Cycle Control
CVD0875/CVD1075/CVD1475/CVD1875/CVD2075
FUNCTION
Energizes and de-energizes the condenser fan motor.
The condenser fan motor typically will be on in the
Freeze cycle and off in the Harvest cycle.
The fan cycle control closes on an increase, and
opens on a decrease in discharge pressure.
CHECK PROCEDURE
1. Verify fan motor windings are not open or
grounded, and fan spins freely.
2. Connect manifold gauges to ice machine.
3. Hook voltmeter in parallel across the fan cycle
control, leaving wires attached.
4. Refer to chart below.
