I recently bought this old dinosaur 25-pfs englander, cleaned it thoroughly installed it, it is working fine, but...as the weather has gotten colder, turning it up to about 9 O'clock (the way the dial goes,) it has begun to whine, and squeal every few minutes....not necessarily at the same time.
Any ideas, suggestions to resolve this would be greatly appreciated
