U-Line Class Series Code E6 (UHWC524, 2224DWR): Thermistor 2 Short

What E6 (Class Series) means

U-Line Class Series wine coolers such as the UHWC524 and the 2000 Series 2224DWR list E6 in the error log table as a shorted Thermistor 2. The second temperature sensor circuit reads as a short, so the control cannot rely on that sensor for temperature.

Common causes of E6 (Class Series)

Thermistor 2 is shorted
The sensor wiring is damaged
The connector has moisture

✓ One safe check you can try

1. Turn off the power for a minute and turn it back on. 2. Record the cabinet temperature on a separate thermometer. 3. Keep the rear of the cooler dry. 4. Do not open any cover. 5. Call us if E6 repeats.

! Why to stop there

Shorts are located by testing
We separate the sensor from the harness before replacing
You get the price first in writing, and a 30-day warranty covers our work

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.
