Hello, I have a Clare Megasave (HEG80B) which is about 20-25 yrs old. This morning a sound started coming from the blower motor (Model Emerson K33HXCFE-964). It is a whirring or a metal scratching. Similar to the original posters sound. After that sound goes on for about 1 minute the pilot ignites and then after another minute to rest of furnace kicks in and the blower goes out.
Is there anything I can do aside from replacing or rebuilding this motor?
Here is a link to the pictures of the part in question.
Any help is greatly appreciated.
