My MIL has an old Crosley dryer model CDE20T6W. It has a push to start timer and it's getting to where it won't start sometimes when pushed. Can I clean something inside it to make it work better? The timer is NLA but I have found a few on ebay both new and used $99 for new. Most of the dryers on CL are at least that. If I could clean some contacts and make it work for free she would love it since she's on a fixed income.
