U-Line Class Series Code E5 (UHWC524, 2224DWR): Thermistor 1 Short

What E5 (Class Series) means

U-Line Class Series wine coolers such as the UHWC524 and the 2000 Series 2224DWR use E5 for a shorted Thermistor 1. The error log table lists it as the shorted reading for the first temperature sensor. The control sees the sensor circuit as a short, so it cannot use that sensor until the circuit is repaired.

Common causes of E5 (Class Series)

Thermistor 1 has a short
The sensor wiring is pinched
The connector is damp

✓ One safe check you can try

1. Power off, wait a minute and power on. 2. Test the cabinet air with a separate thermometer. 3. Keep the back of the cooler dry. 4. Do not take off any cover. 5. Call us if E5 repeats.

! Why to stop there

Finding a short needs a meter
We check sensor and wiring separately
You get a written price first, and our repair has a 30-day warranty

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.
