Fisher & Paykel Refrigerator Error Code INV-16

INV-16 indicates a fault within the inverter module, confirmed by the inverter's onboard LED flashing 16 times. The inverter module controls the variable-speed compressor, and this code means the module has detected an internal error it cannot recover from on its own. The result is typically a compressor that will not run, leading to a loss of cooling in the refrigerator.

With an active INV-16 fault, the compressor is likely not running, which means the refrigerator is not maintaining safe food storage temperatures. Perishable food should be moved to another refrigerator or cooler as soon as possible. Continuing to run the appliance in this state will not damage additional components, but food safety is a real concern.

A power reset may temporarily clear the error display, but if the inverter module has a genuine internal fault, the INV-16 code will return once the unit attempts to run the compressor again. Resetting the appliance is not a fix for this error. The inverter module needs to be inspected and most likely replaced to resolve the fault permanently.

Replacing the inverter module requires working near high-voltage components in the compressor compartment, so this repair is best handled by a qualified appliance technician. A knowledgeable DIYer who is comfortable with electrical safety precautions could attempt the replacement, but the compressor compartment must be fully de-energized before any work begins. Mishandling high-voltage components poses a serious risk of injury.

Repair costs vary depending on the specific model and your location, but expect to spend somewhere in the range of $200 to $550 when accounting for the inverter module part and labor. If the compressor has also been damaged, total costs can be significantly higher. Getting a diagnostic estimate from a certified technician before authorizing the repair is recommended.
