Unit will not power on, display shows E01 or flashes briefly then shuts off

Safety First: Unplug the ice maker or switch off the dedicated breaker before removing any panels. Use a non-contact voltage tester to confirm power is off.

• Step 1 – Verify wall power: Plug a lamp or meter into the outlet feeding the U-Line ice maker. Confirm 115V (or local spec). If no power, reset the breaker or contact an electrician.
• Step 2 – Inspect power cord and inlet: Pull the unit out carefully. Check the power cord for cuts, burns, or kinks. Ensure the cord is fully seated in the rear receptacle and the outlet.
• Step 3 – Access control board: Remove the lower front grille and/or rear access panel (varies by model). Locate the main control board (often in a plastic housing near the compressor area).
• Step 4 – Check harness connections: Inspect all plugs on the control board for looseness, corrosion, or heat damage. Reseat each connector firmly.
• Step 5 – Check internal fuse (if equipped): Many U-Line boards have a small glass or blade fuse. With power disconnected, remove and test continuity with a multimeter. Replace only with the same rating.
• Step 6 – Look for board damage: Examine the control for burnt spots, bulged components, or a burnt smell. If present, the board is likely failed.
• Step 7 – Replace control board: If outlet power is good and wiring/fuse are intact but E01 persists, replace the main control board. Transfer one connector at a time to avoid miswiring. Reassemble, restore power, and test.

If you are not comfortable working around mains voltage, contact a qualified appliance technician.
