How it shows: PCBHR104 unitary diagnostic display in Goodman service manual RS6200007 r27. Digit 3 is blank. Digit 2 is d and digit 1 is 1. The code is d1
Likely causes
- The unit is wired as a communicating system and the integrated control module contains invalid shared data, or the network data is invalid for that module
Safe checks for d1
- Write down d1. It is not d0 (no shared data) and not d2 (system mismatch)
- Technicianverify communicating or legacy wiring, populate the correct shared data with Bluetooth Shared Data Loader BTSDL01, or wire the system as a legacy system
- Technicianturn power off before the repair, insert the loader before power is turned on, and turn power off before the loader is removed
Safety firstOutdoor units carry line voltage even when the thermostat is off. Switch off the unit's disconnect and breaker before touching anything. Refrigerant, wiring, compressor and control-board work must be done by a licensed HVAC technician.
Capacitors can hold a charge after the power is off. Safety terms.
When to call a pro
Call a licensed HVAC technician. d1 means the shared data or network data was rejected as invalid.
