Master Troubleshooting & Diagnostics Matrix
| Error Code / Indicator | Symptom / Meaning | Possible Cause | Step-by-Step DIY Fix | Suggested Actions |
|---|---|---|---|---|
N/A | Fan control does not respond or emit a single beep to remote commands | Command not received by the fan control, remote in standby mode, or depleted batteries | Wake the remote from standby by pressing any of its buttons, check/replace its 2 AA batteries, or make sure it has a clear line of sight and is close enough to the unit. | DIY Safe |
N/A | Fan motor does not start when switched on | Cover hood is not sufficiently open (safety switch active), blown fuse, or 12 V power supply interrupted | Make sure the cover hood is fully open (or open at least 5cm/2in for thermostat/automatic operation, 10cm for model 2250). Check and replace the 4A fuse behind the black cap, and confirm there's a 12V DC supply. | DIY Safe |
N/A | Cover hood is stuck and will not open | Seal has dried up due to warm weather causing the cover hood to stick | Open the cover hood fully, clean the underside with methylated spirits or solvent, apply a water-based protectant (e.g. 303 Protectant), let it dry, buff with a soft cloth, then run an even bead of silicone along the seal - replace the seal if it's damaged. | DIY Safe |
