Another good suggestion. However, this too can't be the cause. I had the
thermo switch disconnected and turned the fan on using a jumper wire. That
started the fan. Fan continued to run endlessly even after I removed the
jumper wire (thermo switch still not connected).

Other suggestions?

Cheers,
Bruce
