Worst experience ever! Karl came to fix the bottom lights on an over the range microwave for my mom. The microwave itself was fully functional when he arrived. An hour later nothing worked. He claimed it was one of two circuit boards which would need replacement. The cheap one was $450 and if it needed the expensive one it would be over $800! I called Kitchenaid. One is $69 and the other is $190. 100% incompetent and dishonest. Now they won’t even return my calls. Brutal.DO NOT WASTE YOUR MONEY
