This 2 year old oven failed last week. ALL the appliances in my house
are dying - central vac, dryer, fridge, wall oven, microwave within 3
months. Even my alarm clock is threatening to die. The dryer, fridge
and oven are the same age, but the vac is much older, micro and clock
much newer. Is there anything that could cause mass appliance death?
