When Your Cooker Hood Fan Isn’t Working: Troubleshooting Tips and Solutions

The modern kitchen is a hub of activity, and a cooker hood plays a crucial role in ensuring the space remains clean and free from unwanted odors. However, it can be frustrating to discover that your cooker hood fan is not working, especially when the light continues to operate. This article will delve into possible causes and provide effective troubleshooting tips to help you diagnose and fix the issue.

Understanding the Cooker’s Role

Before jumping into the troubleshooting procedures, it’s important to understand the role of a cooker hood. Cooker hoods work by removing smoke, grease, and odors produced while cooking, thus improving air quality in your kitchen. They come equipped with fans that either vent air outside or filter it and recirculate it back into your kitchen.

Why Your Cooker Hood Fan Might Not Be Working

When the fan on your cooker hood stops working while the light remains operational, there are several potential reasons behind this malfunction. Understanding these can help you pinpoint the problem:

Electrical Issues

One of the most common causes of a cooker hood fan malfunction is an electrical issue. Power surges or electrical shorts can prevent the fan from receiving the necessary current to operate while allowing the light to work.
