Kitchen Hood Repair

Safe checks before you call a technician

1. Clean the aluminum filters Unplug the hood first. The filters usually unclip from underneath. Soak them for an hour in hot water with dish soap and baking soda, rinse, and let them dry fully before refitting.
2. Check the exhaust duct Look at the duct behind the hood: is it kinked, crushed or full of bends? If the outside vent is safely within reach from a balcony, clear any nest or leaves — never climb a ladder or lean out of a window; call a technician instead.
3. Use high speed when frying Switch the hood on a few minutes before cooking and use the highest speed when frying or grilling — low speed cannot keep up with the smoke.

1. Unplug and look at the fan Unplug the hood or switch it off at the breaker, then remove the aluminum filters. If you can see something caught in the fan (paper, an insect), pull it out by hand with the power off — do not poke in metal tools.
2. Check the mounting For a wall or under-cabinet hood: switch off the power and tighten the visible screws. For an island hood hung from the ceiling that seems to move: stop using it and call a technician.

Safe checks before you call a technician

1. Check the basics Check the plug and socket, and try every speed. If the lights work but the fan does not, power is reaching the hood and the fault is in the motor or its controls.
2. Power it off and on Unplug the hood for 5 minutes, then plug it back in — on hoods with an electronic control board this sometimes clears a freeze. If you smell burning, do not try again.

1. Soak in hot water Unplug the hood and take out the filters. Fill the sink with very hot water, a cup of dish soap and half a cup of baking soda, and soak the filters for 30–60 minutes.
2. Scrub with a brush Scrub the filters with a soft brush in circles — the grease lifts easily after soaking. Avoid steel wool, which scratches the aluminum.
3. Rinse and dry Rinse the filters in clean water and let them dry completely before refitting them.
4. Dishwasher If the manual says the filter is dishwasher-safe, wash it on its own on a normal program. Aluminum may darken slightly; that does not affect how it works.

1. Replace the bulb Switch off the power and let the bulb cool for a few minutes (halogen gets very hot), then remove the glass cover if there is one, take out the old bulb and fit one with the same voltage and wattage. Do not touch a new halogen bulb with bare fingers — skin oil shortens its life.
2. Check the bulb type Make sure the new bulb has the same type and base (G4, G9, E14 or GU10, depending on the model) — never fit the wrong type or a higher wattage.

1. Dry the panel Wipe the touch panel with a dry cloth and leave it off for an hour — steam and moisture are a common reason it stops responding.
2. Clean the panel Clean it with a microfiber cloth and a mild glass cleaner (not an oily kitchen cleaner) — grease stops the sensor detecting your touch. Spray the cleaner onto the cloth, not onto the panel.
3. Reset the power Unplug the hood for 10 minutes, then plug it back in — this can clear a frozen control board.

Safe checks before you call a technician

1. Fresh batteries Fit new batteries of the same size and check the + and − direction.
2. Test the remote with a phone camera For an infrared (IR) remote: open your phone camera (the front one usually shows it best), point the remote at it and press a button. If you see a light flash at the tip, the remote works and the problem is in the hood. RF or Bluetooth remotes will not show up this way.
3. Re-pair the remote The pairing steps differ by model — follow the instructions in your hood manual.

Safe checks before you call a technician

1. Clean the filters straight away Unplug the hood, take out the filters and clean them by soaking and scrubbing (as in the dirty-filters fault). If the filters are old and worn, replace them.
2. Empty the grease channel If the hood has a grease channel or cup under the filters, empty it and wash it with hot soapy water.
3. Clean the hood body Unplug the hood first, then clean the body inside and out with a degreaser — without spraying water or cleaner onto the lights or the control panel.

Safe checks before you call a technician

1. Check the mounting Wall or under-cabinet hood: switch off the power and tighten the visible screws. Ceiling-hung island hood that seems to move: stop using it and call a technician straight away — do not climb a ladder to tighten it yourself.
2. Check the filters Make sure the filters are properly seated and latched — a loose filter rattles and makes noise.
3. Clean the fan blades If you can reach the fan easily once the filters are out and the hood is unplugged, clean the grease off the blades — uneven grease throws them off balance.

Safe checks before you call a technician

1. Check the breaker If the kitchen breaker has tripped, reset it once. If it trips again, leave it off and unplug the hood — there is a short circuit and it needs a technician. If you smell burning, do not switch it on at all.
2. Check the socket Plug a small appliance (a lamp or charger) into the same socket. If it works, the socket is fine and the fault is in the hood.

Safe checks before you call a technician

1. Check your hood type Check whether your hood recirculates air into the kitchen (it needs a carbon filter) or is ducted to the outside (it usually does not).
2. Check the filter Unplug the hood and take out the aluminum filters — the carbon filter is usually behind or above them. Carbon filters are black when new, so the color tells you nothing; go by the interval in your manual, or replace it when smells linger even though suction is fine.
3. Replace it Order a carbon filter that fits your model (the part number is in the manual), original or compatible. Changing it is usually simple. Most carbon filters cannot be washed — unless your manual says it is a regenerable long-life filter.

Safe checks before you call a technician

1. Look at the outside vent If the outside vent is safely within reach from a balcony, clear any nest, leaves or grease. If it is not, never climb a ladder or lean out of a window — call a technician instead.
2. Inspect the duct Unplug the hood and look at the duct behind it: straighten it if it is kinked or crushed. If it comes off easily, clean the inside with a long brush.

Safe checks before you call a technician

1. Try every speed Try each speed in turn and note exactly which ones work and which do not — it saves the technician time diagnosing.
2. Power reset If the hood has an electronic control board, unplug it for 5 minutes and plug it back in — sometimes the board regains control of the speeds.
