Troubleshooting
To check the unit control board for proper operation:
Disconnect thermostat wires at the control board.
Jumper the desired test input (Y1, Y2, W, O, or G) to the R terminal with the SW2-8 in the “OFF” position to simulate a
thermostat signal.
If control functions properly:
- Check for thermostat and fi eld control wiring (use the diagnostic inputs mode).
4. If control responds improperly:
- Ensure that component being controlled is functioning (Compressor, Blower, Reversing Valve, etc.)
- Ensure that wiring from control to the component is functioning (use the diagnostic outputs mode).
- If steps above check properly, replace unit control.
Note: Verify that air and water fl ow rates are at proper levels before servicing the refrigerant circuit.
