Common Commercial Exhaust Fan Repair Issues
If you hear unusual sounds of rattling or notice an excessive vibration in the exhaust fan, then know that these are the signs of an out-of-order exhaust fan, and it’s time to call for an Alturas emergency repair service. Following are some of the signs that a commercial or industrial exhaust fan needs an emergency repair:
- Worn-out and broken fan belt
This is one of the common issues with kitchen exhaust fans. Check for any squeaking sounds and cracks in the belt.
- Sheaves and coupling tension:
Ensure that the sheaves and couplings of the exhaust fans are tight and don’t have an excess play. If there is excessive play in the fan pulley, it needs to be immediately replaced.
- Slow fan movement
The dirt is accumulated very easily on the blades of the exhaust fan with continuous use. Check the fan blade’s movement, if they are moving freely without any friction, it means the condition of the blades is fine. If they are not moving freely, then the blades might need lubrication or emergency repair service.
- Inappropriate belt tension
If the exhaust fan belts are too loose or too tight, it can affect the functioning of the exhaust fan.
- Blockage in air ducts
The exhaust ducts get messy while running a commercial kitchen. The Grease build-up in the air ducts can be a big problem as it blocks the air. It is harder for odors and smokes to travel through ducts or chimneys. The diameter of the ducts decreases, thus preventing fumes from escaping to the roof.
- Dirty Air Filters
A kitchen exhaust fan accumulates a lot of dirt and grease on the filters in an attempt of expelling cooking vapors and steam from a commercial kitchen. Dirty filters are a sign that your kitchen exhaust fan needs service.
- Burnt exhaust fan motor
The concentration of waste in the form of fats, grease, and oil deposits can accumulate in the exhaust fan motor. Resulting in the fan’s motor seizing or completely burnt out.
- Power Issues
Sometimes, there can be an interruption in the electric supply affecting the exhaust fan function.
- Worn out bearings
If your fan is producing unusually loud sounds, it indicates a problem with the fan bearing. Ensure the surface temperature is within range and check the oil rings and watch for excessive end play.
- Rattling and buzzing sounds
A kitchen exhaust fan that rattles while operating is likely to have loose or defective components like fasteners or screws, that need to be rectified.
