Whirlpool Refrigerator Diagnostic Codes: What Each Code Means

Quick Answer

Enter Whirlpool refrigerator diagnostic mode to read stored fault codes and run individual component tests. See the step-by-step entry sequence below. Diagnostic mode stores the last several error events so you can diagnose intermittent faults that clear between uses.

Reading codes requires entering diagnostic mode first by holding Freezer Temp + Fridge Temp for 3 seconds. Each code points to a specific component that needs testing or replacement.

Frequently Asked Questions

What does Whirlpool refrigerator code E1 mean?
E1 indicates the defrost temperature sensor (also called the defrost terminator or bi-metal thermostat) is reading out of range or has an open circuit. The defrost cycle cannot complete without a working sensor, which leads to ice buildup in the freezer.
What does E5 mean on a Whirlpool refrigerator?
E5 indicates the freezer evaporator fan motor is not running or sending feedback to the control board. Without this fan, cold air cannot circulate through the freezer and refrigerator compartments, causing warming.
What does E6 mean on a Whirlpool refrigerator?
E6 points to the condenser fan motor at the back of the refrigerator near the compressor. This fan removes heat from the condenser coils. If it fails, the refrigerator overheats internally and loses cooling efficiency.
Is the CF code serious on a Whirlpool refrigerator?
CF (condenser fault) can indicate a condenser fan issue, a dirty condenser coil, or a communication fault with the control board. Start by cleaning the condenser coils and checking the fan. If CF persists, the control board may need inspection.
My refrigerator shows PO in diagnostic mode. Is that a problem?
PO simply means the refrigerator detected a power interruption (power outage, unplugging, or tripped breaker). It is an informational record, not a component fault. Press any button to acknowledge and clear it.
