What to do, according to the manual
While a cycle is running, go to the Energy section and read the voltage.
Call service when low or high voltage is suspected.
Where it applies
Listed for the UCBF659, UCBF632, UCBF559, UCBF532 and UCBF432, all with the touch screen controller.

Repair for blast chiller voltage alarms in the Bay Area
If the Energy section shows voltage that looks low or high, call (415) 329-7078. Share the reading, the model number and the time it appeared. Our U-Line freezer repair information covers San Francisco calls.
Model compatibility: U-Line reuses codes across series and model years, so ELECTRICAL FEEDING may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
Supply voltage is outside the safety range set by the MRV parameter, plus or minus 20%.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
