U-Line Class Series Code E2 (UHWC524, 2224DWR): Thermistor 2 Open

What E2 (Class Series) means

Class Series U-Line wine coolers such as the UHWC524 and the 2000 Series 2224DWR record E2 for an open Thermistor 2. The error log table for these coolers lists it with the other sensor entries. The second temperature sensor does not complete its circuit, and the control cannot trust its reading until the circuit is repaired.

Common causes of E2 (Class Series)

Thermistor 2 is open
The sensor wiring is broken
The connector is corroded

✓ One safe check you can try

1. Cycle the power off for a minute and then restore it. 2. Measure the cabinet with a separate thermometer. 3. Keep the back of the cooler clear and dry. 4. Do not take off any cover. 5. Call us if E2 repeats.

! Why to stop there

Reading the log is easy, but finding the break needs testing
We check the sensor and the wiring separately
You get our price in writing, and a 30-day warranty comes with the repair

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.
