Are you saying the blower in the indoor does not come on or the condensing fan in outdoor unit?

The condensing fan on the outdoor unit
Expert:  airheatman replied 1 year ago.

You have either a bad fan or bad capacitor.Try using a stick to push start the fan and let me know if it comes on.THen we will want to get a capacitance meter and check the capacitor and a volt meter to check voltage to determine if motor or capacitor is the culprit.

Customer: replied 1 year ago.
Thanks I assumed the start cap may have gone bad But wasn't sure if there is a thermal cutoff on the fan itself. As I mentioned we powered up the unit for the first time this season with the unit covered up with a tarp so the fan would have had a huge airflow resistance . I will try to give the fan motor a nudge under power to see if it runs..

If this is first time it is started, A nudge may solve your problem.Often over winter months it will seize from sitting still.Let me know.If it starts. Let it run a few minutes then cycle off for a few minutes and then back on and see if it starts on its own.
