Quick answer

Before you call

Safe checks you can make

These are simple, non-hazardous checks only. If anything is unclear, stop and contact a technician.

  • Record the exact display string shown (including flash patterns)
  • Record the full U-Line model number from the rating label
  • Confirm doors/drawers are fully closed and seals are clear of debris
  • Perform a manufacturer-approved power restart once if safe to do so

Important safety warning. Do not open internal panels, access high-voltage wiring, or attempt sealed refrigeration work. Never bypass safety devices. If you see smoke, sparks, a burning smell, or water near electrical parts, switch the appliance off at the outlet if it is safe to do so and call a professional.

Please avoid

What not to attempt

  • Do not open internal panels or access high-voltage components
  • Do not open or attempt to recharge the sealed refrigerant system
  • Do not bypass door switches, safety devices or interlocks
  • Do not keep running the appliance if there is water near electrical parts, a burning smell or sparks
