E5
Whirlpool Refrigerator
Severity: ModerateWhat Does This Error Mean?
The E5 error on a Whirlpool refrigerator points to a fault with the defrost thermistor or the ice maker thermistor, depending on your model. The thermistor reads temperatures to control defrost timing and ice production. When it fails, the refrigerator may ice up or the ice maker may stop working. Replacing the faulty sensor typically resolves the issue.
Affected Models
- WRF535SWHZ
- WRS325SDHZ
- WRF767SDHZ
- WRT318FZDW
- Whirlpool models with ice makers and automatic defrost
Common Causes
- The defrost thermistor near the evaporator coil has failed electrically
- The ice maker thermistor (on models with built-in ice makers) has developed a fault
- The wiring from the thermistor to the control board is damaged, pinched, or disconnected
- Ice buildup has encased the sensor, causing it to read incorrect temperatures
- The main control board has failed and is generating a false E5 error
How to Fix It
-
Unplug the refrigerator for 5 minutes. Plug it back in and allow it to run for 30 minutes. Check if E5 has cleared.
Temporary sensor errors can sometimes clear with a simple power reset.
-
Check the freezer or ice maker area for excessive frost or ice buildup. If ice has accumulated around the sensor probe, it must be defrosted manually before the sensor can read correctly.
Unplug the unit and let it thaw with the doors open for 24 hours to clear ice-bound sensors.
-
Locate the E5 thermistor. On most Whirlpool models, it is in the freezer near the evaporator coil or in the ice maker housing. Consult your model's parts diagram to confirm.
Some Whirlpool models have multiple thermistors with different error codes for each — verify which sensor corresponds to E5 in your model's service manual.
-
Disconnect the thermistor and test it with a multimeter. Check resistance matches expected values at known temperatures (approximately 10,000 ohms at 59°F / 15°C).
An open or shorted reading confirms the thermistor has failed and needs replacement.
-
Replace the thermistor, reassemble the refrigerator, and restore power. Confirm E5 is gone and that temperatures stabilize within normal range over the next few hours.
The refrigerator may take 4 to 6 hours to fully stabilize after a thermistor replacement.
When to Call a Professional
E5 thermistor replacement is a DIY-friendly repair. Parts cost $15–$50 depending on the sensor type. If the sensor tests fine but E5 persists, the issue may be in the control board. A technician can run a full diagnostic to pinpoint whether it is the sensor or the board.
Frequently Asked Questions
Does E5 mean my ice maker will stop working?
It depends on your model. On models where E5 is the ice maker thermistor, the ice maker will likely pause or stop. On models where E5 refers to the defrost thermistor, the ice maker may still work but defrosting will be affected. Check your model's manual or service documentation to confirm which sensor E5 refers to.
How do I know if my Whirlpool refrigerator has multiple thermistors?
Most modern Whirlpool refrigerators with ice makers and auto-defrost have at least two or three thermistors. The refrigerator compartment sensor, the freezer sensor, and the defrost sensor are common. Some models also have an ice maker or dispenser thermistor. Your model's service manual or parts diagram will list each sensor and its associated error code.
Can I use a generic thermistor instead of the Whirlpool part?
You should use the OEM part or a confirmed-compatible replacement. Thermistors are not universal — the resistance curve must match the control board's expectations. A thermistor with the wrong resistance values will cause incorrect temperature control even if it does not show an error code. Always match the part number from the refrigerator's model number.
