Light comes on and heats up on top oven even when not switched on, so bought new thermostat, but now don't know who to remove casing to fix it! The cooker is a dipolmat range 850 dual fuel range cooker ADP 5426.Advice please.

Hi Dennis,

Very common problem this sounds like.
Others have changed the Thermostatt without any change.

I had an Engineer call out to mine couldnt see the fault so wanted to take it away to look into... Not possible !

Now put up with the problem as no-one to my knowledge has been sucessful.

4 years now and counting !
