Tips for Repairing the Kitchen Exhaust Fans

It's quite easy to fix the problem that develops in the hood during the operation. We're going to mention some problems and their corresponding solutions. Let's have a look!

Device Doesn't Turn On

If there is no main supply, a fuse problem may occur in the system. 

How to Repair: In the case when the kitchen exhaust doesn't respond to any manipulations, you need first to pay attention to the outlet. Check the voltage using a special device. If the output power is working and the system won't turn on, it's time to look at the control board or fuse. Otherwise, the power surges problem can occur in the system.

Poor Performance

If the fan doesn't work, the reason for this could be clogging or breakdown in the ventilation impeller.

How to Repair: you need to clean the necessary parts with water using special solutions. If necessary, replacement of the metal or disposable filter is required. You can also replace the fan if it isn't working properly. Generally, metal filters are disposable and reusable. These filters are pure adsorbent and eliminate odours. 

Increased Noise Level

If the hood is noisy, this signals possible malfunctions.

How to Repair: The operation of any device for purifying the smoke should be accompanied by a slight noise. Its level and intensity will depend on how fast the fan is spinning. The reason for the noise is the fastening force of the fan, which could weaken over time due to the force of vibrations. Hence, if the part isn't secured properly, the kitchen hood may generate additional noise. So, check the shaft and duct part of the hood to remove the residues of debris. 

Controls Aren’t Working Properly

One of the possible malfunctions is that the controls of exhaust fans aren’t working properly due to breakage in the wires.

How to Repair: Before replacing the control buttons, it’s necessary to check the possibility of repair. This can be done with a special tester in resistance test mode. Before checking the controllers in another socket, pay attention to its nominal voltage. It must be the same as that used in the hood.

If all devices are working properly, it's possible that the problem is hidden in the operation of the switch. You need to buy control buttons with the nominal voltage and are in working conditions.

Conclusion!

The kitchen exhaust repair and maintenance are essential to keep it running smoothly. If you fail to repair the exhaust fans, it’s time to take help from cleaning service providers.
