It is normal for heat pumps to go into defrost mode. When this occurs, your reversing valve switches to it's cooling position, the outdoor fan turns off, the compressor runs, and your defrost board energizes the electric heat strip.
That said, capacitors and fan motors can and do fail. Did you monitor it for very long, or pass by and notice the compressor running with no condenser fan.

It came on once when I put in the new thermostat, but I have not seen it come on at all sense then.

When you state that your outdoor fan is not running, are you referring to the entire outdoor unit?

the outside fan came on when i turn the A/C on, but has not kicked on at all with the heat. Is that normal? or did i blow something?
