Monogram Refrigerator CC Error: Compressor control fault
The CC code indicates a cooling system or compressor control fault. The main control board has detected that the compressor is not responding to cooling commands, or the compressor control circuitry has reported an internal fault condition.

Answer to continue safely
Is it safe to keep using?
No. A CC fault means the compressor is not running and neither compartment is cooling. Food will reach unsafe temperatures within 4 hours. Move all perishables immediately and call for service.
Can I reset the code?
No. A power cycle may temporarily clear the code, but CC indicates a genuine hardware failure that will immediately recur. Professional repair of the inverter board or compressor is required.
When to stop immediately?
Stop if you notice: Neither compartment is cooling at all — food safety is immediately compromised, remove all perishables., You smell burning electronics or see discoloration near the compressor area — unplug immediately..
Symptoms You May Notice
Refrigerator and freezer not cooling
Both compartments warm up progressively as the compressor is unable to run or maintain the refrigerant cycle needed for cooling.
Compressor not starting
The compressor (located at the rear bottom of the unit) does not hum or vibrate as it normally would during a cooling cycle.
CC code on display with alarm
The control panel displays CC and sounds an alarm tone indicating a critical system fault has been detected.
Condenser fan not running
The condenser fan motor that cools the compressor and condenser coils may also be stopped, as it is triggered by the same compressor control signal.
Possible Causes
Inverter board (compressor driver) failure
Monogram units with variable-speed linear or inverter compressors use a separate inverter board to drive the compressor. Failure of this board triggers the CC code and stops the compressor.
Requires ProfessionalCompressor failure
The compressor motor windings have failed (open, shorted, or grounded), preventing it from starting. This is a major mechanical failure.
Requires ProfessionalCompressor start relay failure
On older or non-inverter models, the start relay or overload protector has failed, preventing the compressor from receiving the startup current it needs.
Requires ProfessionalMain control board fault
The main control board is not sending the correct compressor run signals due to a firmware or hardware fault on the board itself.
Requires ProfessionalSafe Checks You Can Do
-
1
Check for adequate ventilation
Ensure the refrigerator has at least 1 inch of clearance on sides and 2 inches at the rear. A compressor that overheats due to poor ventilation will shut down on thermal protection and may trigger CC.
On Monogram built-in units, verify the grille and ventilation cavity at the top of the unit are not blocked by cabinet trim.
-
2
Clean the condenser coils
Locate the condenser coils (typically behind the base grille or at the top rear on built-in models). Use a vacuum with a brush attachment to remove dust and debris that could cause overheating.
Dirty condensers are a leading cause of compressor overload shutdowns. Clean every 6–12 months.
-
3
Power cycle the unit
Unplug the refrigerator for 5–10 minutes, then restore power. Listen for the compressor to attempt to start within 5–10 minutes. A click followed by humming that dies indicates a start relay issue.
Record audio of the startup attempt to share with a technician for faster diagnosis.
When to Call a Professional
Contact a qualified technician if:
- All CC causes — inverter board, compressor, start relay, main board — require a certified technician with refrigeration and electrical expertise.
- Compressor replacement involves refrigerant recovery, EPA 608 certification, and specialized evacuation and recharge equipment.
