I have a Maytag Frdige, The Freezer was cold the Fridge was not cooling very well. Armando from America's same day service came and was in the property alone because I couldn't be there. He says it was low on freon and he charged me 240.00 to add freon. in 2 weeks, the fridge was not cooling again. I had a different company check it out and they were very honest, With 53 years of experience with Refrigerators, He was 100% positive there was never Freon added to that Fridge and you can tell because there was no access point to add Freon. It was untouched as is from the factory. To add Freon, there would have to be a valve inserted into the coil to inject the Freon, The 2nd Technician inspected it and found no evidence Freon has ever been added. The problem was the thermostat setting was wrong and there is a door inside that connects between the freezer and fridge that was left open.
