Government documents show an estimated 147,000 fires every year are caused by kitchen appliances. Many are the result of human error, but a frightening new Consumer Reports investigation reveals some appliances may be defective.

Whirlpool, which owns Kitchenaid, says it has not been able to verify a single report of a self-starting microwave.

GE told consumer reports that, "It has investigated unverified reports of 'self-start' and found them to constitute product quality, not product safety, concerns."

GE goes on to say many have been determined not to be 'self-starts' at all.

It you're experiencing a problem with any appliance, Consumer Reports says notify the manufacturer immediately. And report the problem to www.saferproducts.gov.
