Whirlpool Refrigerator Diagnostic Mode: How to Read Stored Error Codes

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.

To enter Whirlpool refrigerator diagnostic mode, press and hold Freezer Temp Up and Refrigerator Temp Up simultaneously for 3 seconds. The display switches to service mode and scrolls through stored fault codes. Each code corresponds to a specific component: E1 is the defrost temp sensor, E2 is the ambient sensor, E5 is the freezer fan, E6 is the condenser fan. After reading codes, press both buttons again or unplug to exit.

Frequently Asked Questions

Which Whirlpool refrigerator models support this diagnostic mode entry sequence?

The Freezer Temp + Fridge Temp hold method works on most Whirlpool French door and side-by-side refrigerators made after 2010, including WRF and WRS series models. Some older models require unplugging and holding different button combos.

How long does diagnostic mode stay active?

Diagnostic mode remains active until you manually exit by pressing the button combination again, or until the refrigerator times out after approximately 5-10 minutes of inactivity.

Can I clear fault codes from diagnostic mode?

Yes. On most models, unplugging the refrigerator for 60 seconds will clear stored codes. Some models allow code clearing from within diagnostic mode by pressing and holding Start or holding the exit button sequence for an additional 3 seconds.

What does it mean if no codes appear in diagnostic mode?

If no codes appear, either there are no stored faults or the issue is intermittent and has not triggered a code. You can also manually run component tests from within diagnostic mode on supported models to force-test individual parts.

My refrigerator does not have the Freezer Temp and Fridge Temp buttons. What do I do?

Older Whirlpool refrigerators with dial controls do not have a button-based diagnostic mode. Check your model number and look up the specific service manual entry sequence, or contact Whirlpool support with your model number.
