People often use the term “cooker” left, right and centre Cooker Hood Switch when referring to food heating appliances. Some talk about the microwave and call it a “microwave cooker”. Others point at the oven and call that the cooker.

The cooker must be connected to a cooker control unit, above. It must be connected via the correct size cable and this may vary but is directly related to the power of the cooker. See our table on cable sizes and check the rating of your cooker.

The cooker control unit fits to a patress box, just like a socket outlet or switch and may be flush or surface mounted. Some cooker control units offer simple switching facilities but others include a socket.If a 13amp socket is included an additional demand of 5 amps is placed on the circuit and your cable and switches must reflect this increse.

Cooker control units also come with neon lights to signify that the unit and/or switch is turned on and the current is reaching the unit.

If your oven's control knobs are broken or the numbers are worn off, it's easy to replace them with brand new one.

There are different types of knob but I will show you the main types.The first knob is held with a tension plate inside which keeps the pressure on the shaft to stop the knob falling off.

This last type is a bit more elaborate, this sits flush in the cooker facial panel and when pressed pops out, it still has a pin inside holding it to the shaft but can fail on the spring system inside.

The second type has a sprung metal case around the plastic shaft to stop the plastic splitting therefore holding the knob onto the shaft.

This last type is a bit more elaborate, this sits flush in the cooker control facial panel and when pressed pops out, it still has a pin inside holding it to the shaft but can fail on the spring system inside.
