How to Fix / Troubleshooting
Safety: Always verify the outlet with another appliance before opening the cooler. Unplug before accessing internal components.
- Outlet and breaker: Test the outlet with a lamp or phone charger. Reset any tripped breaker or GFCI.
- Inspect power cord: Look for cuts, burns, or crushed sections. Replace the Luma power cord if damaged.
- Access control board: Remove the rear or top panel to reach the main board. Look for an onboard fuse and check continuity with a multimeter. Replace with the same rating if blown.
- Board replacement: If the fuse is good but the board shows burn marks or no output voltage, replace the Luma power/control board.
