We got all new kitchenaid appliances when we moved in 2011. I've replaced oven heating elements, microwave door latches/switches, ice maker doors, motors, and circuit boards. the only time a professional came was for a refrigerant leak. Same for the 2011 Samsung gas dryer; it's been dismantled multiple times to clean lint, and I had to replace an igniter last year. I use appliancepartspros .com for most everything. They have phone support and a forum that have both been super helpful.
