My old refrigerator came with the house I bought last year and it was starting to make these loud banging noises, it was disconcerting at first, I thought there was a monster in the kitchen. The damn thing started coughing up blood a week ago, the fridge section stayed around 55F and the freezer goes from -10F to 55F depending on its mood and what the monster is plotting for the night.
I went to Home Depot last week and bought a new GE fridge but the scheduled delivery date is August 28, which could change they say, probably not for the better I would guess. Anyway, I'm living on cheese, crackers, bananas and Jim Beam for the next week and am using my Coleman cooler to keep the cheese from spoiling. Just sharing my woes, thanks for listening and give your fridge a kiss and thank it for working hard 24 hours a day.
I've been shopping, too. The same issue that is hitting the auto market hits the appliance market - - the microchip shortage. When I look at Lowes here, half the models are not available. If you're in desperate shape, check out the used market. Resale on used refrigerators tends to be pretty low.
