BEKO CXF5083W FF Fridge/Freezer. Not Cooling.

[ColinRegan]

Hi All,
I have a Beko Frost-Free Fridge Freezer, model num CXF 5083W. Its about four years old.
It just suddenly stopped cooling in both sections.

I turned it off for a several days. There is a thing about ice buildup in drainage areas, and some water came out, not much.
When switched on the compressor seems to start up and run ok, but only for a few mins, then stops.
I’ve checked the thermostat setting, its a electronic type. Basically it’s a variable resistor, which is wired to a control board somewhere. I dont know where.
I removed the thermostat unit, and with a multimeter checked the variable resitor changing as I moved the setting wheel.
Checked at the wiring plug end too. All seems good.
I can find a replacement for the board easily, and it’s cheap, but I really think I don’t need it.

So what next to check, and in what order ?

Could it be the main compressor ? Is this a DIY job ?
What about the compressor start relay ? I’ve found a supplier for these, but £30 each, non returnable.
Could it be leaked gas ? How to check and fix ?
Could it be the main control board ? Where is it ?
Anything else ?

Does anyone have a parts list and/or exploded diagram to work out where the various parts are, like the main control board, the compressor starter relay etc ?

Any help apprecaited.

Cheers, Colin.

Could it be the main compressor ?
If the comp starts and runs for a few mins and then shuts off it could be going off on klixon or possibly lp, when it runs does it get really hot?

Is this a DIY job ?
If you are a fridge/white goods engineer and have the correct qualifications to be working on refrigerants then yes, if you have no training, qualifications and/or experience then no.

What about the compressor start relay ? I’ve found a supplier for these, but £30 each, non returnable.
If it started okay i would rule that out as an issue at the moment.

Could it be leaked gas ? How to check and fix ?
Could be short of refrigerant, you would need a trained professional to check and repair due to either being a HFC or possibly HC refrigerant, but being domestic it would be cheaper to buy a new unit than to get the comp changed.

Could it be the main control board ? Where is it ?
If you have power at the comp, at the thermostat (if electronic) and at the fans(if fitted) i would also rule the pcb out.

Anything else ?
With fridge it could be a number of things, for it to not be cooling the main parts are, temp probes reading incorrect, thermostat has become faulty, fans not running(only on models with fans) comp not pumping as it should or refrigerant charge.
