Light inside oven flickers

[adamt11]

Hello,

The light inside my oven flickers on and off depending on the temperature it's set on. The light and heat only come on at approx 190, 210 and 230+ degrees; at all other temps the light stays off and the oven doesn't get hot. The cooker on/off switch on the wall remains lit throughout.

What could be causing this problem and how can I fix it?

Thanks

What make and model is your oven?

It will normally be a small edison screw pigmy bulb of some sort.

There could be some dirt in the screw connection which means there is a bad contact. Unscrew the bulb, turn the power off and use an alcohol based lens wipe to give it a wipe round using your finger. The alcohol will evaporate leaving no residue. Clean the bulb screw too.

Also inspect the element. It could be that it is a sign it is about to go.

If so.....replace it!

Edit: I have just seen you said light & heat. If it is specific to where you turn the dial, then it could be a faulty contact on the dial, i.e it is not actually telling the oven to turn on until a specific area of the dial that still works is selected.

The dial mechanics may need replacing (not just the knob).
