The bulb in my machine burned out. Went to dealer bought the new one. Came home, and tried for over an hr. to replace. Old one came out and back in real easy. Thought new bulb wasn't as long as old one. Drove 15 miles to see if other place had the very same kind as old one. No luck. DH asked me why I was having so much trouble. I'm showing him how you have to line it up, push it up, and then turn it clockwise. Its in, and it works! He knows better than to say anything.
