?

I have a new Candy electric oven. It has just started to require the dial on the front panel to be adjusted in order for the light to come on i.e for the oven to actually come on. It feels like there is a connection issue as it comes on then goes off then comes on again if I adjust the dial. Problem is I cant leave it as it sometimes goes off on its own. It feels like as I turn on the dial and adjust it, the connection or wire is intermittently connecting
