3 weeks ago my Samsung refrigerator, which I bought about 7 years ago, stopped cooling in the fridge compartment, the freezer continued to freeze at -2 degrees.
To make a long story short, I had a repair guy come in and he replaced the defrost heater in the fridge along with 2 other parts. It cost me $750! But A new fridge would have cost about $2000 with sales tax and all the other crap.
But the next morning after it was "repaired", my wife smelled something burning in the fridge. So I opened it up as I had seen him do and I saw the heating unit he installed was the wrong size and was fit outside the metal shield that surrounds the cooling coils and defrosting unit. The heater was literally melting and burning the plastic lining of the fridge compartment! I went on Amazon, (where else) and found the correct parts and ordered them for under $100.
The idiot who did the repair could have burned my house down while my wife and I were sleeping! I called the company back and told them I want a refund for the parts he installed that were the incorrect parts. They are lucky there was no fire.
I should have just bought a new fridge. These things are designed to fail after 5 or 6 years. The repair people just rip you off and have no clue what they are doing.
We renovated out kitchen and laundry room about 7 years ago. We purchased all new appliances including over/stove, a wall over microwave unit, fridge, washer dryer and dishwasher. Every one of these appliances has malfunctioned over the last 2 years, except the dishwasher which came free with the Thermador stove. Every appliance has been repaired and every repair cost at least $500. These are not cheap appliances. They are all quality brands. The moral of the story is, buy regular brands that are lower priced. The expensive ones break just as quickly and cost more to repair. In fact, don't repair them. Buy new ones and expect to replace them in 6 years.
