Control Panel Fault Code Listing
NOTE:
Reference fault code #23*: In ambient temperatures below 0°C, this code may be logged because the low ambient causes a temporary low gas pressure.
NOTE:
Where the ambient temperature rises above 40°C, with the engine close to overheating, electrical feed to the compressor clutch may be cut and code #23 registered.
Control Panel Fault Code Listing
| Condition | Possible Source | Action |
|---|---|---|
| 0 Normal operation no fault codes present | None | Wait 30 seconds for system self-check. |
