I have an electric dryer that is taking longer and longer times to dry the clothes about 2-1/2 hours to do a standard load. The time seems to be increasing - Is this dangerous? It is probably running my electric bill up? The dryer came with the house I bought a year ago. I would guess the appliance purchased by the previous owners is about 4 years old. I don't know the manufacturer- It is a good quality machine.:)
