Domestic Extractor Fan Repairs in Pretoria
Kitchen extraction and household ventilation diagnosis for fans that stop running, become noisy or no longer clear cooking vapour.
A domestic extractor that lights up but barely moves air may have a restriction rather than a failed motor. An extractor that rattles or hums without turning raises different concerns. Our service begins with how the unit operates and where the extracted air is supposed to travel, rather than treating all extraction problems as identical.
We accept extractor fan repair enquiries from kitchens and household ventilation installations across Pretoria and Centurion. When contacting us, explain whether the fan vents outdoors or recirculates through a filter, what has changed recently and whether the issue affects noise, airflow, switching or the light assembly.
Problems we help investigate
A thorough repair begins by separating the visible symptom from its underlying cause. We consider the whole installation, not only a single component.
Fan runs but steam stays in the kitchen
Grease-loaded filters, obstructed outlets, duct restrictions and insufficient make-up air can reduce effective extraction. A recirculating hood will not exhaust moist air outdoors, even when its motor is operating normally.
Motor hums without rotating
A seized impeller, failed motor assembly or certain electrical starting faults can cause humming. Repeatedly switching it on may overheat damaged equipment and is not a safe troubleshooting technique.
Loud vibration or rubbing
Loose fan mounts, an unbalanced wheel, damaged bearings and contact with the housing produce different noises. The cause must be established before attempting to stabilise the assembly or replace parts.
Fan or lights work intermittently
Switches, control boards, connectors and internal wiring can fail independently of the motor. Moisture or heat exposure may also affect controls, especially in a heavily used kitchen.
Condensation or grease appears around ducts
An ineffective duct route, poor joints, blocked outlet or maintenance issue may cause deposits around the installation. Leakage should be distinguished from ordinary grease accumulation near a filter.
How the problem should be assessed
- 01
We establish whether the hood is ducted or recirculating, how air enters the room and what happens at different speed settings. Filters, visible outlets and the correct use of any charcoal filter are discussed before motor faults are assumed.
- 02
We inspect accessible fan components, supports, electrical controls and duct connections as appropriate. A speed setting that alters motor sound without improving flow suggests a different problem from a unit that never energises. Electrical work must be isolated and performed by qualified personnel.
- 03
After the relevant repair or maintenance, airflow, vibration, unusual smells and control response should be checked. Where duct routing limits performance, that installation issue should be explained rather than promising the fan alone will solve ventilation problems.
Repair quality comes from the right diagnosis
Grease filters protect internal equipment but become restrictive when neglected. Filter cleaning or manufacturer-approved replacement may improve the system markedly. Charcoal filters on recirculating hoods have a different purpose: they help with odour, but they do not replace outdoor air extraction.
An extractor is part of a ventilation route. Duct length, sharp turns, collapsed flexible ducting and an obstructed outside cowl affect the volume of air removed. Changing a motor without looking at this resistance can leave poor performance unchanged and may put the replacement under unnecessary load.
Intermittent tripping or heat-discoloured wiring warrants professional electrical assessment. Fans operated close to cooktops experience heat, grease and vibration over long periods; a reliable repair must address the actual operating environment.

Domestic Extractor Fan Repairs FAQs
Why is there no suction even though the kitchen fan sounds normal?
A loaded filter, blocked duct, poor outlet arrangement or unsuitable recirculating configuration can allow normal motor noise with little useful extraction. The route of the air must be checked.
Can an extractor motor be replaced?
Replacement may be possible depending on model, assembly design and parts availability. A seized wheel or duct restriction should be ruled out before choosing a motor.
Why does my extractor rattle at one speed?
A loose panel, fan imbalance or worn bearing may resonate more strongly at a particular speed. Continued operation can worsen movement or mounting damage.
Will changing the filters remove kitchen humidity?
Clean grease filters help ducted extractors operate efficiently. A recirculating model may reduce grease and odours but does not remove moisture to outdoors.
