I have had a daewoo fridge/freezer (Model ERF-33m) and the light no longer works when you open the fridge door. I've changed the bulb as this had blown, but it will still not come on with the new bulb. I took the microswitch to the repair shop, as i presumed it must be faulty. They tested the switch and said this was working fine, also showed me with the tester. They said they could send someone out to have a look at whats causing the problem. Cant see what else could be causing the fault, looking at the setup, the only thing left can be the cabling to the light fitting or the light fitting itself, are these easy enough to replace??
