Error codeELECTRICAL FEEDING
ApplianceBlast Chiller
Quick answer
ELECTRICAL FEEDING means supply voltage is outside the safety range set by the MRV parameter; the manual suggests checking the Energy reading.
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 outside the safety range set by the MRV parameter.
What ELECTRICAL FEEDING means
The voltage supply is not within the safety range. The MRV parameter, Main Reference Voltage, sets that range, with a band above and below it.
What the manual suggests
Check the actual voltage reading in the Energy section during a cycle for more detail. Call service if low or high voltage is suspected.
Models
UCBF432, UCBF532, UCBF632, UCBF559 and UCBF659 with the touch screen controller.
If the Energy reading looks low or high, phone (310) 879-5776. Share the reading you saw, the model number and when it happened. More on refrigeration service sits on the linked page.
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.
