The door on our $1200 2 year old refrigerator started cracking at the hinge. I had a credit card warranty on it, so I foolishly tried to hire an appliance repair company to fix it. They charged $150 to look at it for 10 minutes and say all they could do is replace the whole door, and quoted $900. I spent 45 minutes fixing it myself with some extruded aluminum and some rivets. The warranty coverage allowed for self-repair, so I ended up "earning" roughly my equivalent hourly rate as a software engineer.
