Fan no longer responding to any adjustments so need parts to replace the whole thing. At 160.00/hour I don't need a diagnose from my service guy. Just want parts to have them replace.

Im approaching 15 grand in repairs since I bought it in 1996 so I was hoping no more, at least for awhile, since the last repair. But do need heat and defrost here in San Francisco.

When you say that it is "no longer responding to any adjustments", do you mean that it runs at full speed all the time - or that it doesn't run at all?

Does not run at all.

The Fan Control amp tends to be failure-prone, and can cause the problem you're describing.

There's a lengthy thread on it here.

The photos are missing in the original post, but have been re-posted on Page 5 of that same thread.

Thank you very much. Ill check it out.
