Hi,
The alarm on the above has been sounding at increasing intervals over a couple of months with no defrosting of both compartments, until this morning when I found both the freezer and fridge had completely defrosted overnight. The alarm was sounding every 10 seconds with the fan then coming on followed by it cutting out and the alarm sounding again.
The electric to both compartments was still being supplied with only the light in the fridge compartment going on & off constantly. I un-plugged the fridge freezer and on plugging it back in the freezer was completely dead. I checked the fuse and it was OK.
Any ideas as to what the problem could be and how I can fix it?
Thanks.

“Over time it appears that the capacitor that makes up part of the firing circuit to the Compressor relay fails. There are four relays on board, three black, one orange (its the orange one that we are interested in as this enables the compressor). The relays are enabled from the microprocessor on the board via a triac controlling the switching of live onto a diode bridge and through a resistor and capacitor on the neutral side. Over a period of time the capacitor will break down and won’t be able to hold enough energy to fire the relay enabling the cooling via the compressor.”
********************************
After much searching looks like the above is the problem. May be more than one capacitor has given up on the rear PCB. I will be sending it to be checked by these guys unless someone knows where I can buy a new one at a resonable price?………..

Sent the circuit board for repair to http://qer.biz/
. Capacitors & relays either not working or transmitting too low a voltage for the compressor to run. All working now for the total cost of £43.20! Circuit board had a 1 day turnaround!! 😀
