I just hauled a duvet of dust out of the fan-cooled condenser coils in the bottom of the fridge, switched fridge off via internal control knob first, carried out the work, all's well, flicked the knob back to the previous setting, internal light comes on, but no fan and no compressor, even when the temp dial is cranked to the max.

I'm about to pop down and check it again incase it has started, wouldn't hold out much hope!

The fact that neither fan nor compressor starts, that tells me its got to be a thermostat/electrical problem.

FYI, It's R22, probably over 13 years old, so I'm not going to complain about replacing it, it's served us well (good 'ole R22, don't make em like they used to )

Back in a bit!
