Common Chimney Problems and Easy Solutions Homeowners Should Know

One of the most crucial but often ignored items in modern homes is the kitchen chimney. It quietly maintains a smoke-free, odorless, and hygienic cooking area. However, chimneys experience problems with time, just like any other equipment, ranging from oil blockage and poor suction to noisy operation.

Be calm if you notice that your kitchen chimney isn’t working as well as it once did. With minor changes or routine maintenance, the majority of chimney issues are readily resolved at home. The most frequent chimney issues, their causes, and easy fixes you can try before contacting a professional are all discussed in this article.

Unusual or loud noises coming from a chimney

Something is wrong if your kitchen chimney has started to make loud cracking, vibrating, or buzzing sounds.

The potential reasons for loud noises are as follows:

Due to loose screws or fan blades
The motor bearings might be Damaged.
There might be grease or oil buildup on the fan
The chimney is not correctly fixed on the wall.

The easy fixes to these problems are as follows:

Make sure the mounting bolts or screws are tight after turning off the chimney.
To get rid of oil buildup, gently wipe the fan blades using a soft cloth.
A damaged motor, which has to be replaced by a specialist, could be the cause of the noise if it continues.

Weak Airflow or Low Suction Power

The kitchen remains smoky after cooking since your chimney isn’t efficiently removing smoke or smells.

The probable causes for low suction power are as follows:

The filters are clogged by oil or grease
A blocked vent pipe or duct
The installation height is incorrect which is either is too high over the stove or too low.
Due to lack of cleanliness caused a decline in motor performance.

The simple solutions to these problems are as follows:

If you frequently cook with oil and spices, clean the filters once every ten to fifteen days.
Baffle filters should be properly washed after 30 minutes of soaking in warm water with a moderate detergent.
Examine the duct pipe for blockages or bird nests, which are a frequent problem with open vent systems in Nepal.
Your chimney may require expert deep cleaning or motor servicing if the suction is still fragile.

Chimney Not Starting or Stopping Suddenly

Your chimney stops operating in the middle when you’re using it, or it fails to turn on.

The probable reasons for poor functioning of chimney are as follows:

There might be problem with the power supply or blown fuse.
A broken electrical wire.
Failure of the internal motor.
A safety mechanism for overheating was activated.

The simple fixes to these problems are as follows:

Yous should confirm that the switch and power outlet are operating correctly.
You should check for loose wire or a burnt smell around the plug site.
You should rest it for ten to fifteen minutes and try again if you think it could be overheating.
A technician may need to repair the control board or motor capacitor if it still won’t start.

Chimney cannot remove smoke in the kitchen

Smoke or oil vapor enters your kitchen even when the chimney is on.

The reasons behind faulty chimney performance are as follows:

Due to several bends in the duct pipe decrease suction flow.
The vent location or duct diameter is improper.
Grease filters might be blocked.
Low suction capacity, which is typical in older models

The simple fixes to these problems are as follows:

Inspect that your duct pipe is small, straight, and ideally has few turns (less than 10 feet).
Regularly clean the motor housing and filters.
Consider switching to a higher-capacity model if you cook by deep-frying and your chimney’s suction capacity is less than 1000 m³/hr.

Oil leaking from Filters or the Chimney

Stains and dirt build up when oil begins to flow down from the chimney’s surface or close to the filters.

The reasons behind leaking of oil from filters in chimney are as follows:

There might be too much oil clogged within the filter
The oil collector tray is blocked.
The inner surface of chimney is cleaned rarely.

The solutions to this problem are as follows:

Every week, the oil collector pan should be taken out and cleaned.
For 20 to 30 minutes, soak the filters in a mixture of baking soda, dish soap, and hot water.
Using a weak vinegar solution, wipe the interior surface and chimney body to remove any sticky grease.
You should avoid using harsh chemicals because it can harm internal components and finish.

Buttons or Touch Panel not working

Some buttons respond slowly, or touch control or buttons are not working correctly.

The reasons behind poor operation of button or touch panel are as follows:

The oil or moisture entered into the control panel.
The damage to the circuit caused by variations in voltage
The PCB board might be outdated or faulty.

The fixes to this problem are as follows:

You should use a dry microfiber cloth to gently clean the control panel.
For chimneys, use a voltage stabilizer (particularly during Nepal’s monsoon power fluctuations).
Depending on the brand, replacing a damaged touch panel can cost anywhere from NPR 2,000 to NPR 4,000.

Bad Odor Even After Using Chimney

Food odors remain in the kitchen even after the chimney is running.

The reasons behind bad odor in kitchen are as follows:

The filters are saturated with grease.
The duct outlet might be blocked or facing the kitchen.
The overuse of carbon filters in duct chimney.

The fixes to this problem are as follows:

For ductless chimneys, change the carbon filters every three to six months.
Baffle or metal filters should be completely cleaned.
You should confirm the duct’s direction and make sure the air outlet is correct.

When to Call a Professional?

Although almost all of chimney issues are simple to resolve at home, you should contact an experienced professional if:

The motor either doesn’t rotate or makes noise.
You detect a burning smell or electric sparks.
Cleaning does not restore any suction.
The touch panel or circuit isn’t responding.

A properly maintained kitchen chimney increases the life of your appliance and keeps your kitchen free of smells and fresh. Regular cleaning and wise use can readily resolve the majority of typical problems, such as low suction, oil leaking, and noise.
