Troubleshoot the Defrost System

WARNING

Electrical Shock Hazard

Disconnect power before servicing.

Replace all parts and panels before operating.

Failure to do so can result in death or electrical shock.

The defrost control is equipped with a set of pins (labeled TEST on control circuit board) to aid in troubleshooting the defrost system. Connecting the test pins speeds up the defrost cycle time by a factor of 256.

1.Disconnect power.

2.Remove control box cover.

3.Connect the test pins on the defrost control using a test jumper wire.

NOTE: If the outdoor temperature is above 32°F, connect the defrost sensor terminals using a test jumper wire. See “Defrost Control Board” in the “Adjust Defrost System” section.

4.Replace control box cover.

5.Reconnect power.

6.Start system in heating operation.

7.Time the defrost test cycle as determined by the chart. After the corresponding defrost cycle time from the chart below has elapsed, the reversing valve should shift to defrost mode and the outdoor fan should stop. After 2 seconds of defrost operation, the reversing valve should shift back to heating operation and the outdoor fan should start.

NOTE: If this procedure is not observed, check the reversing valve solenoid for correct operation by measuring temperatures and pressures under heating and cooling modes. If the reversing valve solenoid operates correctly then replace the defrost control board. See “Sequence of Operation.”
