Michaela S Rochester , WA June 06, 2015 Appliance: KitchenAid Refrigerator KSSS48DAW00 Well we did not know what the problem was at first! refridgerator was warming up Watched a few of your well put together videos and could not afford a new Refrigerator right now because it was a built in so decided with the frost on the bottom of the freezer grill and the Refrigerator warming up decided to replace the Heater Element and Thermostat Defrost which took some time but so far so good lets hope that is all that is needed saved over 10,000.00 dollars for a new 48" built in for now! Thank you for your rushed order and videos I think you are a life saver got the part in 2 days you company is awesome!
