Problems with Kitchen Extractor Fans
Kitchen extractor fans are essential for maintaining good air quality and removing odors while cooking. However, like any other appliance, they can encounter problems over time. In this article, we’ll explore some common issues discussed on a forum related to kitchen extractor fans and possible solutions.
Hood Fan Not Working, Lights Are On
One of the most frequently reported problems is a kitchen extractor hood fan that’s not working, even though the lights are still functional. Users often wonder if accumulated grease is the cause of the issue.
Grease Buildup
It’s true that excessive grease buildup can hinder the operation of the fan. To check if this is the problem, listen for any buzzing or vibration from the fan when it’s powered. If you hear these sounds, it’s likely that grease is causing the fan blades to stick.
Switch Control Board
Another common culprit, especially for fans with multiple speed settings, is the slider switch control board. Over time, the copper tracks on the board can burn through, disrupting the electrical connection. This can lead to a loss of fan functionality while leaving the lights operational.
Testing the Switch Control Board
If you suspect that the switch control board is the issue, you can use a multimeter for testing. Here’s a basic guide on how to do it:
- Safety First: Before starting any electrical testing, ensure that the power to the extractor fan is turned off. Safety is paramount.
- Locate the Control Board: Find the control board inside the fan unit. This may require removing the fan cover or accessing the unit from above the stove.
- Inspect for Damage: Examine the control board for any visible signs of damage, such as burnt or damaged copper tracks, loose connections, or soldered joints.
- Testing with a Multimeter: Set your multimeter to the appropriate setting for resistance (ohms). Touch the probes to different points on the control board, including the tracks and pins, to check for continuity. A lack of continuity indicates a problem with the board.
Seeking Professional Assistance
If you’re uncomfortable performing these tests or unable to identify the issue after inspection, it’s advisable to seek professional assistance. A qualified electrician or appliance repair technician can diagnose and repair the problem safely.
Conclusion
Kitchen extractor fans play a vital role in maintaining a pleasant and healthy cooking environment. When these fans encounter problems, it’s essential to address them promptly. Grease buildup and issues with the control board are common culprits, but with a careful inspection and, if necessary, professional help, you can ensure your kitchen extractor fan continues to function effectively. Remember to prioritize safety when working with electrical components and always turn off the power before performing any tests or repairs.
