Fisher & Paykel Refrigerator Error Code INV-14

INV-14 indicates a communication error between the main control module and the inverter board. The inverter board controls the variable-speed compressor, and this code appears when the data link between these two components fails. The cause can range from a loose wiring connector to a faulty board on either end of the circuit.

The refrigerator may not cool properly while this error is active, since compressor operation can be restricted or stopped. Running the unit in this state puts your food at risk and is not recommended for extended periods. The fault should be diagnosed and resolved promptly to avoid food spoilage.

If only a wiring connector needs to be reseated or cleaned, the repair cost may be limited to a service call fee, typically in the range of $75 to $150. Replacing an inverter board generally adds $150 to $400 in parts depending on the model, while a new control module can add a similar or higher cost. Total repair costs including labor can range from $200 to $600 or more depending on which components need replacement.

Checking and reseating wiring connections on the control module and inverter is a reasonable first step for a confident DIYer. However, if the wiring appears intact and the error persists, diagnosing which board has failed requires technical knowledge and likely a technician. Replacing inverter or control boards involves working around capacitor-stored voltage, so caution is essential.

A power reset by unplugging the unit for several minutes may temporarily clear the code if the fault was caused by a transient signal disruption. However, if there is an underlying wiring or component issue, the error will return once the refrigerator restarts and attempts communication again. A reset is a useful first step but is not a fix on its own.
