E2
Whirlpool Refrigerator
Severity: ModerateWhat Does This Error Mean?
The E2 error on a Whirlpool refrigerator typically indicates a fault with the fresh food (refrigerator) compartment temperature sensor. While E1 usually refers to the freezer sensor, E2 points to the refrigerator section thermistor. The sensor has either failed, is reading an out-of-range temperature, or has a wiring fault. The refrigerator section may warm up if this is not addressed.
Affected Models
- WRF535SWHZ
- WRS325SDHZ
- WRT318FZDW
- WRB322DMBM
- Most Whirlpool French door and bottom-freezer models
Common Causes
- Failed refrigerator compartment thermistor reading incorrectly or sending no signal
- Damaged wiring between the thermistor and the main control board
- Loose connector at the thermistor or at the control board harness
- Main control board unable to read or process the thermistor signal
- Excessive frost or ice blocking the sensor and causing false temperature readings
How to Fix It
-
Unplug the refrigerator for 5 minutes, then restore power. Check whether E2 clears on startup.
Temporary sensor faults or voltage spikes can sometimes be cleared with a power reset alone.
-
Locate the refrigerator compartment thermistor. It is usually found near the back wall or attached to the evaporator cover inside the fresh food section.
Refer to your model's service manual or the wiring diagram inside the unit for exact thermistor placement.
-
Inspect the thermistor and its wiring for signs of damage, moisture, or frost accumulation.
Heavy frost can cover the sensor and insulate it, causing inaccurate readings that trigger E2.
-
Disconnect the thermistor from its connector and test resistance with a multimeter.
At 70°F (21°C) the sensor should measure around 10,000 ohms. Values far outside this range indicate failure.
-
Replace the thermistor if it fails the resistance test. Reconnect the wiring carefully and restore power.
If E2 returns after thermistor replacement, the main control board may need inspection or replacement.
When to Call a Professional
Thermistor replacement is a straightforward DIY repair costing $20 to $60. Control board replacement runs $100 to $300. If food in the refrigerator section is warming, act quickly to avoid spoilage. A technician can quickly confirm the fault with a resistance test.
Frequently Asked Questions
Is E2 different from E1 on Whirlpool refrigerators?
Yes, they are different sensors. E1 typically refers to the freezer compartment thermistor. E2 typically refers to the fresh food (refrigerator) compartment thermistor. Both are diagnosed and repaired the same way — the only difference is which sensor and compartment is affected.
How do I know if the refrigerator section is getting too warm?
Place a thermometer inside the fresh food section and check after one hour. The refrigerator should maintain 35–38°F (2–3°C). If it is above 40°F (4°C), bacteria can grow on perishables. Move sensitive items to a cooler while you diagnose the issue.
Can I use any thermistor as a replacement for E2?
No — use a Whirlpool OEM or approved aftermarket part for your specific model. Thermistors have specific resistance curves that the control board is calibrated for. Using the wrong thermistor can cause incorrect temperature regulation even without an error code.
