The extractor hood on your cooker is essential for ridding your home of cooking smells, especially where you have an open plan house or a kitchen-diner. The cooker hood also helps to remove grease from the air as you cook and light the hob as you cook, so a malfunctioning unit can be problematic.
If the light is not working then this could be simply a blown bulb. The instruction manual will show you how to replace the bulb and these are usually a standard item that you can buy at the supermarket or a DIY store. If this does not solve the problem then you should call out an electrician, as the switch or lighting unit may have failed.
These will be replaced in most cases and your electrician will probably have to order a unit in or go off to a supplier, as they vary greatly from model to model.
The most common extractor hood problem is a failure of the fans that remove smells and grease from the air as you cook. For this reason, it is always advisable to clean your extractor hood on a regular basis so that you avoid build-ups of grease. Your instruction manual will give you an idea of how to remove and/or replace the filters on your cooker hood.
If the fans fail then you will notice either a complete lack of noise from the hood, an increase in noise or a rattling noise In all these cases the fans will either fail to extract odours from the room or be less efficient at doing so. In some cases the problem will be with the wiring or switches, but in most cases the problem is simple wear and tear on the motor that drives the fans. This can easily be replaced by your electrician once he has established the cause of the problem. In other cases it may be that the fan or some fan blades have come loose. Your electrician will be able to tighten up and secure the fan unit to make sure that it works correctly.
