Whirlpool Refrigerator Error Codes: WRF and WRS Series Fault Guide

Quick Answer

Whirlpool refrigerator error codes appear on the display as letters and numbers. Common codes: E0 = defrost temperature sensor, E1 = fresh food thermistor, CF = condenser fan, IF = ice maker fan. Start with a power reset (unplug 5 minutes). If the code returns, look it up in the sections below - each one has a specific repair path.

Whirlpool WRF and WRS series refrigerators display fault codes on the interior control panel. Common codes include E5 (temperature sensor out of range) and PO (power outage recorded). Enter diagnostic mode by holding Freezer Temp and Fridge Temp buttons simultaneously for 3 seconds to see all stored codes. E5 requires sensor testing and likely replacement. PO is informational only and cleared by pressing any button.

Frequently Asked Questions

How do I enter diagnostic mode on a Whirlpool WRF or WRS refrigerator?
Press and hold both Freezer Temp Up and Refrigerator Temp Up buttons at the same time for 3 seconds. The display will switch to service mode and scroll through any stored fault codes.
Is the E5 error on a Whirlpool refrigerator serious?
Yes. E5 indicates a temperature sensor is out of range, which means the refrigerator cannot accurately monitor or control temperatures. This can lead to food spoilage if left uncorrected. Diagnose and repair within a day or two.
What does PO mean on a Whirlpool refrigerator?
PO stands for Power Outage. It is an informational alert, not a component fault. The refrigerator recorded a power interruption and is notifying you to check food safety. Press any button to clear the PO message.
Are WRF and WRS error codes the same?
Yes. Whirlpool WRF (French door) and WRS (side-by-side) refrigerators use the same control board platform and the same error code definitions. Diagnostic procedures and repair steps are identical across both series.
My Whirlpool refrigerator shows a code not listed here. Where can I find a complete list?
The complete fault code list is in the service manual specific to your model. Access the service manual by searching your full model number (e.g., WRF535SWHZ) on the Whirlpool service documentation portal or through a third-party appliance repair parts site.
