Compressor circuit error: the control board detected a compressor circuit fault such as overcurrent, a start-relay failure, or the compressor not responding.

What PC means on your Whirlpool refrigerator (whirlpool refrigerator pc error)

The whirlpool refrigerator pc error is a compressor circuit error: the control board detected a fault in the compressor circuit, such as an overcurrent condition, a start-relay failure, or the compressor not responding to commands. Both compartments warm toward room temperature, and you may hear clicking every few minutes as the unit tries and fails to start the compressor. A failed start relay is sometimes owner-checkable, but a failed inverter board or compressor requires a technician.

Symptoms

The signs below help confirm you are dealing with this condition rather than a different fault on your Whirlpool refrigerator. You may notice one of them or several together, and they can appear gradually or suddenly after a power event, a wash or cook cycle, a spill, or recent installation or service.

  • Both compartments warming to room temperature
  • Clicking every 2 to 5 minutes
  • Compressor area hot to the touch
  • Complete silence from the unit

Common causes

Several different faults can produce these symptoms. Working through the most likely causes in order separates a quick owner-level check from a problem that needs trained service and the correct Whirlpool parts.

  • Failed compressor start relay — the relay that starts the compressor has failed (sometimes owner-checkable by feel and inspection).
  • Failed inverter board — on inverter models, the board driving the compressor has failed.
  • Failed compressor — the compressor itself has failed and is not responding.
  • Compressor overcurrent — the circuit is drawing abnormal current, tripping the fault.

Troubleshooting steps you can try

Work through these checks in order before calling for service. Stop wherever you are unsure, or where mains voltage, gas, a hot oven cavity, water, or a sealed component is involved, and hand the rest to a qualified technician.

  1. Unplug the refrigerator and, if accessible, inspect the compressor start relay; a rattle when gently shaken often means it has failed.
  2. Let the compressor cool for about 30 minutes before restarting, since it may have overheated.
  3. Listen for repeated clicking that signals failed start attempts.
  4. Do not attempt any work inside the sealed compressor circuit; this is technician territory.

Parts a technician may replace

Depending on what the diagnosis shows, a technician may inspect, test, or replace the compressor start relay, inverter board, and compressor. The correct part for your Whirlpool refrigerator is matched from the model and serial number, and genuine OEM components are fitted through trusted parts suppliers rather than generic substitutes so performance, safety, and the appliance long working life are all protected. Confirming the failed part before ordering avoids replacing more than the fault actually requires.

When to call a technician

A technician should diagnose the start relay, inverter board, and compressor and replace the failed component, since PC rarely clears on its own. Because this condition is rated High severity, it is safest to stop using the refrigerator and arrange service promptly rather than keep retrying, and to shut off power or water at the source if anything looks, smells, or sounds unsafe. As an independent repair service we are not affiliated with the manufacturer, and we work only with experienced, skilled technicians and genuine OEM parts from trusted parts suppliers, with our workmanship backed by a 30-day labor warranty. When you book, have your Whirlpool refrigerator model and serial number ready so the right part for your exact build can be matched before the visit and the PC condition resolved in as few trips as possible.
