21 COOLING CYCLE CHECK

Alarm Type

Prevent Alarm

Associated Alarm
Codes

Alarm Code 23 Cooling Cycle Fault
Alarm Code 84 Restart Null
Alarm Code 85 Forced Unit Operation

How Alarm is Set

The unit was exhibiting a heating temperature differential (

∆

T) while operating in cool mode.

How Alarm is Cleared

This alarm is cleared automatically or manually.

Considerations

1. This is a Prevent alarm. A second occurrence of this alarm will be set as Alarm Code 23 Cooling Cycle

Fault shutdown alarm.

2. If restarts are disabled, Alarm Code 23 will be set as a shutdown alarm on the first occurrence of the alarm.

Diagnostic Procedure

Download and review the ServiceWatch data logger using Technician Level to determine the conditions at the time
the alarm was set.

1. Check temperature differential by displaying the temperature differential, or by checking the difference

between the control return and control discharge sensors.

2. Check refrigerant level.

3. Attach gauges and evaluate unit refrigeration system performance.

4. Verify that sensor grades are set correctly.

5. Check for proper air flow. Short cycling, caused by a blocked air flow path, may generate this code.

6. Check the three-way valve. A defective valve that does not return to the cooling position may cause this

alarm.

7. Check the pilot solenoid valve. A defective valve that is stuck open will prevent the three-way valve from

shifting to the cooling position.
