New cooker switch light not working, loose wire?

[Oliver Gould]

Hi,

I recently had a new cooker switch installed, the day after he installed it the red light on top stopped working. I am slightly worried there may be a loose wire; the cooker still powers up so the switch is doing it’s job. Should I be concerned or is it most likely to be just the bulb?

Don’t worry. Just call the installer back. There should be no charge. The law is on your side.

It is most likely a poor connection to the neon.

Really don’t know why people fit cooker switches with neons. The red light is irritating and after a few years they go black.
