Monogram Freezer CC Error: Compressor control fault
The CC code on a Monogram freezer indicates a compressor control fault. The control board cannot start or communicate with the compressor, or the compressor inverter drive has detected an internal fault, resulting in no refrigerant compression and complete cooling failure.

Answer to continue safely
Is it safe to keep using?
No. A CC fault means zero cooling is occurring. Frozen food begins to thaw immediately. Remove all food to alternative frozen storage and contact a service technician without delay.
Can I reset the code?
No. A 30-minute power-off may allow a thermally tripped overload to reset temporarily, but if the underlying cause is not corrected (dirty condenser, failed component), the compressor will overheat and trip again quickly.
When to stop immediately?
Stop if you notice: Freezer food is visibly thawing or at temperatures above 0°F — transfer food immediately, discarding anything fully thawed., You detect a burning smell or see discoloration near the compressor or inverter board — shut off power at the circuit breaker..
Symptoms You May Notice
Freezer completely unable to maintain temperature
The freezer compartment warms to ambient room temperature as the compressor is unable to run and the refrigerant cycle has stopped entirely.
Compressor silent — no vibration or hum
The compressor (typically at the rear base or bottom of the unit) produces no sound or vibration during a compressor run cycle.
CC code with alarm on display
The Monogram display shows CC and sounds an alarm, indicating a critical compressor system fault has been detected by the control board.
No airflow heat from condenser area
The condenser area at the rear or base of the unit is not warm as it normally is during compressor operation, confirming the compressor is not running.
Possible Causes
Inverter board (variable speed drive) failure
The inverter board that converts AC power to variable-frequency drive for the linear or variable-speed compressor has failed — a common fault point on post-2015 Monogram freezers.
Requires ProfessionalCompressor motor failure
The compressor motor windings have failed (open, shorted, or grounded to ground), making the compressor unable to run under any conditions.
Requires ProfessionalCompressor thermal overload
The thermal overload protector on the compressor has tripped due to overheating (often from a dirty condenser or poor ventilation) and has not reset — the unit needs to cool down before the overload resets.
DIY PossibleStart relay failure
On models with a conventional compressor, the start relay has failed, preventing the capacitor-start circuit from delivering startup current to the compressor.
Requires ProfessionalSafe Checks You Can Do
-
1
Allow unit to cool and power cycle
If the condenser area is extremely hot, the compressor thermal overload may have tripped. Unplug the unit for 30 minutes in a well-ventilated area, then restore power. Listen for the compressor to start within 10 minutes.
Simultaneously clean the condenser area — a fouled condenser causing overheating will just trip the overload again.
-
2
Clean condenser and verify ventilation
Vacuum the condenser coils thoroughly through the base grille or rear access. Verify the unit has the required clearances on all sides. Inadequate ventilation is the primary non-component cause of compressor overload.
For Monogram ZIF column freezers, check that the top vent grille and the toe-kick ventilation are both clear.

3
Shake the start relay
With the unit unplugged, access the compressor (typically behind the rear access panel at the base). Locate the small start relay plugged into the compressor's side terminal. Remove it and shake it next to your ear. A rattling sound indicates the relay has failed internally.
A new start relay is an inexpensive part ($15–40) and is worth trying before assuming compressor failure — but only on models with conventional (non-inverter) compressors.
When to Call a Professional
Contact a qualified technician if:
- All CC causes beyond condenser cleaning require a GE-authorized technician — inverter board, compressor, and start relay replacement all involve electrical safety risks and refrigerant system considerations.
- Compressor replacement requires EPA 608 certification for refrigerant recovery and recharge.
