Beko CF7914APS Fridge/freezer – Model SN-T

Hi.We noticed both compartments warming up on the above fridge freezer. Light is on. Compressor will occasionally start up and run for a few minutes other times it can be seen/heard trying to start. I’ve followed some online guides re: checking the pins of the compressor and the PTC relay with a multimeter and the results seemed satisfactory. Anything else I can try, to breathe some life into it? Her indoors has already started looking about for a replacement just thought I’d have a bit play while the decision making process is in full swing.
