Troubleshooting
Standard Microprocessor Controls
To check the unit control board for proper operation:
1. Disconnect thermostat wires at the control board.
2. Jumper the desired test input (Y1, Y2, W, O or G) to the R
terminal to simulate a thermostat signal.
3. 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
(refer to the LED Defi nition table below and use the diagnostic
outputs mode).
• If steps above check properly, replace unit control.
