Fisher & Paykel Refrigerator Error Code 1

Error code 1 on a Fisher & Paykel refrigerator indicates that the compressor has failed to start after 6 consecutive attempts by the control system. The compressor is the heart of the refrigeration cycle, responsible for compressing refrigerant gas and circulating it through the condenser and evaporator coils. When the control system detects that the compressor is not starting within the expected parameters after repeated attempts, it locks out and displays this fault code to prevent further damage to the system.

The diagnostic process begins with checking the compressor windings for faults. A failed compressor typically shows as an open circuit, short circuit, or a winding-to-ground fault when tested with a multimeter. If the winding resistances are out of specification or show a direct short, the compressor itself has failed internally and will require replacement. This is a mechanical or electrical failure within the sealed refrigeration system.

If the compressor windings test within acceptable limits and show no faults, the issue moves upstream to the power/control module. The power/control module is responsible for delivering the correct starting voltage and control signals to the compressor. A faulty module may fail to provide adequate start current, send incorrect signals, or have internal component failures that prevent a successful compressor start sequence. In this scenario, replacing the module rather than the compressor resolves the fault.
