I have a side by side adjectives in 1 fridge/freezer. It is an intermittent glitch and now and after it is not getting cold enough. I hold had it for just about 6 months and this started about a week ago. Its a factory 2nd so is out of warranty. Any suggestions please.
Answers:    check the rank of freon gas in the cooling circuit. The compressor may be failing. (hope not it's an expensive repair). You may obligation a technician to do the refilling. (it can be harmful in a minority of freezer models. An alternative is to contact an appliance repair shop to receive the problem dianosed and an estimate on repair if needed.
