We always get the extra extended warranties for our appliances, despite having it on our Gold VISA card.
We have had to make several service calls just to check on something and it more than pays for the extended warranty in and of itself. Sears charges $75.00 just to walk in the door.
Minor repairs on HE washers or HE dishwashers are very expensive. eg. Our dishwasher cost $1000.00, so it is worth it to protect it. We buy all of our appliances through Sears, so for approx. $250/year on our: dishwasher, fridge, HE washer and over the range microwave, we get all service calls, labour, parts, and yearly maintenance checks and cleanings. Baby boy broke the crisper drawer which is $150 to replace, and during our regular yearly inspection last week, they replaced it for free. We have more expensive appliances, and so paying $20.00 a month is ok by us.
We have had great luck with Seas, and are getting ready to buy a new stove, and will do the same as well for it.
Today's appliances are not made like they they used to be. Like I said, we buy higher end models, and keep our stuff in pristine condition, but due to cheaper parts, things break or need extra servicing, so Sears maintenance plans are great.
Good luck, Tiger
