Heat Pump Fan inop

I believe I've found the problem, but I would like confirmation before I jump in with a wrench, a screwdriver and a check book.

Indications:
1. Front unit- No cooling.
2. Found CB tripped. Reset it.
3. Turned the unit on, heard a low, steady rumble, but no fan. I believe the rumble was the compressor. Turned the unit off.
4. Took the roof cover off. Squirrel cage fan did not readily turn. After applying more force, it reluctantly turned, and eventually it would spin freely.
5. Re-started the unit- same results as in #3. Using a screwdriver (to keep from chopping off a finger) I tried to get the fan to turn. It wouldn't.
6. Large cylinder, which I assume to be the compressor, was running, as determined by feeling it vibrate.
7. The fan motor was EXTREMELY hot to the touch. The amount of time it was attempting to run was less than 5 minutes.
8. Once again, after shutting it down, with some effort, I was able to get the fan to again spin freely

My conclusion is I will have to replace the fan motor. Does that sound correct? What recommendations or cautions would the experts among you have to offer? Is it likely that damage may have been done to other components?

Thank you all for the help.

Hi Jim, Sounds like a good logical aproach, back it up with available line voltage readings and borrow an amp clamp to check load. My fans overheat and are slow to start when shore line voltage is low. Skip 2002 Intrigue #11329
