Common Cooker Hood Faults
I repair a wide range of common cooker hood problems, from simple faults to more involved electrical, control and heating issues.
| Cooker Hood Fault | Possible Causes |
|---|---|
| Cooker hood not extracting properly | Blocked grease filters, saturated carbon filters, restricted ducting, tired fan motor, poor installation or airflow obstruction. |
| No power | Blown fuse, faulty socket, damaged power cable, failed control switch, loose wiring or control board fault. |
| Fan not working | Faulty fan motor, failed control switch, capacitor fault, wiring issue, jammed fan blade or control board fault. |
| Fan running slowly | Worn motor, blocked filters, grease build-up, capacitor fault, restricted ducting or poor airflow through the appliance. |
| Very noisy when running | Loose fan blade, worn motor bearings, grease build-up, loose mounting screws, vibration from ducting or damaged fan housing. |
| Rattling or vibrating | Loose fixings, loose ducting, unbalanced fan blade, damaged motor mount, loose filter cover or poor installation. |
| Lights not working | Blown bulb, faulty LED module, failed lamp holder, wiring issue, transformer fault or control switch fault. |
| Light flickering | Loose bulb, failing LED driver, poor connection, faulty switch, damaged lamp holder or internal wiring issue. |
| Buttons not responding | Faulty control switch, damaged push-button assembly, touch control fault, moisture ingress, loose ribbon cable or PCB fault. |
| Touch controls not working | Moisture or grease on control panel, failed touch module, damaged control board, loose connection or power supply fault. |
| Cooker hood tripping electrics | Moisture ingress, motor fault, damaged wiring, failed lamp circuit, mains filter fault or internal short circuit. |
| Burning smell | Grease build-up, overheating motor, electrical fault, blocked filters, damaged wiring or failing control component. |
| Grease dripping from cooker hood | Blocked or saturated grease filters, heavy grease build-up inside the hood, poor cleaning, incorrect filter fitment or poor airflow. |
| Steam or smells not clearing | Blocked filters, old carbon filters, weak motor, incorrect recirculation setup, restricted ducting or undersized cooker hood. |
| Recirculating hood not removing smells | Carbon filters need replacing, filters fitted incorrectly, poor airflow, blocked grease filters or worn fan motor. |
| Ducted hood not venting outside | Blocked duct, crushed ducting, failed backdraft flap, poor installation, external grille blockage or fan motor issue. |
| Speed settings not working | Faulty selector switch, failed control board, capacitor fault, wiring issue or motor winding fault. |
| Cooker hood switches itself off | Overheating motor, blocked airflow, faulty thermal protection, control board issue, loose connection or failing switch. |
| Remote control not working | Flat battery, failed receiver board, faulty remote, control board issue or loss of pairing on compatible models. |
| Error code showing | Filter warning, motor fault, control board issue, sensor fault, touch control fault or manufacturer-specific appliance fault. |
