How to Fix / Troubleshooting

Safety first: Turn off power at the breaker before opening the unit. Only work on mains wiring if you are qualified.

Steps to restore power:

1. Confirm outlet power: Test the GPO with another appliance.
2. Inspect power cord: Check for visible damage; replace if cut or crushed.
3. Check internal fuse: Remove the cover and locate the fuse on the Gliderol control board. Replace with the exact same rating if blown.
