When working with extractor fan checks, a quick visual and functional test to confirm your fan is moving air correctly. Also known as vent fan inspection, it helps keep indoor air clean and stops moisture damage. A well‑functioning extractor fan not only removes cooking fumes but also keeps mold at bay. electrician, a licensed professional who can safely handle wiring and motor issues may be needed for complex problems, but many checks you can do yourself. filter maintenance, regular cleaning or replacement of the fan’s grease filter is a key factor that influences performance and energy use. Checking an extractor fan encompasses visual inspection, sound check, and airflow test – three simple steps that give you a clear picture of its health.
Start by turning off power at the circuit breaker – safety first, even if you think the fan is off. Once the electricity is cut, remove the front grille and give the filter a once‑over; greasy buildup is the #1 cause of weak suction. If the filter looks dirty, soak it in warm, soapy water, rinse, and let it dry fully before reinstalling. Next, give the fan housing a visual scan for loose wires, rattling screws, or cracked ducts. A loose connection can cause intermittent operation, while cracked ducts let air escape, reducing efficiency. Plug a small handheld beanie or a piece of tissue into the vent and feel for airflow – a strong, steady stream means the motor is working; a weak or uneven flow suggests a clogged duct or a failing motor. Listen for unusual noises: humming indicates the motor is running, but grinding or squealing often points to worn bearings that need professional attention. If you have a simple anemometer or even a rolled‑up piece of paper, you can measure airflow speed to compare with the fan’s specifications, which you’ll find on the motor label.
When the inspection reveals obvious issues – a dirty filter, loose wiring, or blocked vent – you can usually fix them yourself with basic tools: a screwdriver, a soft brush, and cleaning supplies. However, if the motor stalls, the fan makes grinding noises, or you notice burning smells, it’s time to call a qualified electrician or a vent‑service specialist. Remember, working on the motor’s internal components often involves live wires and can be hazardous without proper training. By keeping a regular cleaning schedule and noting any changes in performance, you’ll extend the life of your fan and avoid costly repairs. Below, you’ll find articles that walk you through each of these steps in detail, help you decide when professional help is needed, and give you quick fixes for the most common extractor‑fan problems.
