Fisher & Paykel Refrigerator Error Code INV-10

INV-10 indicates a fault detected within the inverter module, which is the component that controls the variable-speed compressor. The fault is identified by the inverter's onboard LED flashing 10 times. This error means the inverter module has failed internally and needs to be replaced. The refrigerator's cooling performance will typically be compromised while this fault is active.

Continuing to operate the refrigerator with an active INV-10 fault is not recommended. The inverter module controls compressor operation, so a failure here means the compressor may not run correctly or at all, putting food safety at risk. There is also a potential for further electrical damage if the underlying fault condition is not addressed promptly.

A power reset may temporarily clear the displayed error, but it will not resolve the underlying inverter module fault. Because INV-10 reflects an internal hardware failure within the module, the fault code will return once the refrigerator powers back up and the inverter self-tests. Permanent resolution requires replacing the inverter module.

The repair involves replacing the inverter module, which is located in the compressor compartment and connected to high-voltage circuitry. While a knowledgeable DIYer may be able to source and install the part, working near compressor wiring carries electrical safety risks. It is generally advisable to have a qualified appliance technician perform the replacement to ensure safe handling and correct installation.

Repair costs will depend on the price of the replacement inverter module and labor charges in your area. Parts alone can range from roughly $150 to $400 depending on the specific model, with labor adding an additional $80 to $200 or more. Getting a quote from a technician before proceeding is a good way to weigh repair cost against the age and value of the appliance.
