Fridge we have is sealed pretty good. Bought it around '08 after the economy crashed. Lowe's had a sale on all appliances. Was only looking at replacing our cook stove ancient gas job. The deals were just to irresistible. Ended up getting a front load washer and dryer less than half price and that fridge, and our first dishwasher. Pretty funny when they delivered them. Delivery guys thought there was a mess up. What do you mean? Well we have a white stove, black dishwasher and stainless fridge. We didn't buy them for their color buddy, just the price lol.
Big double French door stainless fridge freezer on the bottom back then I think was $1,700, we got it for $600 which we would never had spent 6 on a fridge on but couldn't pass it up.
Took a crap after about a year on the freezer, iced up, ice everywhere inside and water pouring out of it. Lucky we had Google then . Many reviews people spending $$$ to fix it. One reviewer actually said how he fixed it. Take plate off the back access the drip pan thing where the moisture is supposed to drip and fan dry it out, rubber nipple on the end, clean it out. Sure enough, big black fly stuck in it...
No probs for yrs 10-12 yrs. Few months ago same thing. Took it all apart again few weeks ago, crap, lint dust IDK crap stuck in it. Freezer dry now no ice buildup good to go
