7 Troubleshooting Using Error Codes
The last digit in the check error codes in the 4000's and 5000's and two-digit detail codes indicate if the codes apply to com-
pressor inverter on fan inverter.
Example
Code 4225 (detail code 108): Bus voltage drop in the fan inverter system
Code 4230 : Heatsink overheat protection in the compressor inverter system
