Maytag Refrigerator Error Code CP

The CP code on a Maytag refrigerator stands for a compressor output fault detected during service mode diagnostics. It means the refrigerator's control system ran a diagnostic check and found an issue in the compressor circuit. This can involve the compressor itself, the start relay, wiring, or the control board output. The code is retrieved by entering Service Mode Option 1.

A CP fault code means the compressor circuit has a detected problem, which can lead to reduced or no cooling. Continuing to use the refrigerator with this code active risks food spoilage if the cooling system is compromised. It is best to address the fault promptly rather than leaving perishable food at risk.

Resetting the refrigerator by unplugging it or cycling the power may temporarily clear the code from the display, but the underlying compressor circuit fault will remain. The code will return when the control system runs diagnostics again if the root cause has not been repaired. A proper repair of the faulty component is required to permanently resolve the CP code.

Some steps, like inspecting wiring connections or replacing a start relay, are manageable for a knowledgeable DIYer. However, diagnosing the control board output voltage and replacing a compressor require technical skills and specialized tools. If you are not comfortable working with electrical components, a qualified appliance technician should handle the repair.

Repair costs depend heavily on which component has failed. Replacing a start relay is typically on the lower end, ranging from around $10 to $50 for the part. A compressor replacement is significantly more expensive, with parts and labor potentially ranging from $300 to $700 or more depending on the model and local labor rates.
