How to Fix / Troubleshooting
Safety first: Before opening the unit, ensure the outlet itself is safe and functional.
- Outlet test: Plug a lamp or other small appliance into the same outlet to verify power. Reset any tripped breakers or GFCI outlets.
- Power cord inspection: Check the NEEDONE power cord for cuts, burns, or kinks. Do not use the unit if the cord is damaged; replace it.
- Internal fuse: Some models have an internal fuse on the main control board. With the unit unplugged, remove the rear panel, locate the board, and inspect/replace the fuse if blown (use the same rating).
- Board connections: Ensure the incoming power wires are firmly connected to the main control board terminals.
- Replace main board: If power is present at the board but nothing powers on, the main control board may be defective and require replacement.
