Answer to continue safely
Is it safe to keep using?
No. The freezer cannot maintain safe temperatures with E2 active. Move frozen food to another freezer to prevent spoilage.
Can I reset the code?
No. A reset may temporarily clear the display, but E2 will return until the faulty sensor or wiring is repaired.
When to stop immediately?
Stop if you notice: Stop and call a technician if the freezer temperature is above 10°F (-12°C) and rising., Stop if you find frost or ice packed around the thermistor connector — defrost service is needed..
Symptoms You May Notice
Freezer not holding temperature
Frozen food softens or partially thaws as the freezer compartment climbs above 0°F (-18°C) without correction.
E2 displayed on panel
The touchscreen or LED display shows E2 and may emit a beeping alarm.
Excessive frost build-up
Without accurate temperature sensing, the defrost system may not activate at correct intervals, causing frost to accumulate on the evaporator coils.
Ice maker stops producing
The ice maker relies on freezer temperature data; with E2 active it may halt production as a protective measure.
Possible Causes
Defective freezer thermistor
The sensor has failed open or shorted, sending an invalid resistance to the main board.
DIY PossibleDisconnected or corroded harness
The wiring loom between the freezer thermistor and PCB has a loose plug or oxidized terminal.
DIY PossibleControl board malfunction
The board's sensor-reading circuit has failed even though the thermistor itself is good.
Requires ProfessionalSafe Checks You Can Do
-
1
Perform a soft reset
Hold the freezer temperature Up and Down buttons simultaneously for 10 seconds (model-dependent) or unplug for 60 seconds. Check if E2 clears.
Consult your model's user guide for the exact key combination for diagnostic reset.
-
2
Check freezer thermistor connector
Remove the freezer back panel to access the thermistor. Unplug and firmly re-seat the connector. Look for frost intrusion into the connector body.
Dry any moisture from the connector with a paper towel before re-seating.

3
Measure thermistor resistance
At 0°F (-18°C) the freezer thermistor should read approximately 32–36kΩ. A reading of 0Ω or open-line means the sensor needs replacement.
Warm the sensor slightly in your hand — if resistance drops proportionally, the sensor is functional.
Tools required
When to Call a Professional
Contact a qualified technician if:
- Thermistor resistance is correct but E2 persists — control board replacement required.
- Evaporator coils are blocked with a solid ice mass requiring professional defrost service.
- Unit is within the Dacor warranty period — self-repair may void coverage.
