SOURCE: ruud heat pump outside fan
You may be right in looking at the motor. It uses a different speed on heat than cool. The heat cycle uses low speed, usually red. Some manufactures use blue (medium). Cool uses black, high speed. If you are confident, switch the low speed wire with the high speed and see if this changes anything. If the fan motor isn't the problem, check the other setting (cool) if the overload trips, you may need to look into a new capacitor or compressor, if so, you can install a hard start kit. these are start boosters, and are inexpensice, sometimes they will give another year out of the comp. but I've put them on and they have lasted 5 years.

Have you checked the freon level in this unit? If you are low or there is a leak it could be the problem. Hope this helps.

Hi, the outdoor unit will start to freeze when it is cold outside, but also it should go into a defrost mode to melt this ice either by the defrost board or defrost thermostat. You will know as steam will rise like smoke and some folks think it is on fire. If it never goes into defrost, get back to us and we can go through some things to check. Merry Christmas,

What you described 'shouldn't' be happening - "if" the outside fuses and the inside breaker are sized correctly for your air conditioner.
I would make sure that the fuses in your outside disconnect were the proper size (for your AC), and that the inside breaker was of suffienct size to handle the air conditioner, and whatever else might be on the circuit.
Note: You would never want the 'outside fuse size' to be bigger than the inside breaker.
For example: 50 amp fuses in the outside disconnect and a 40 amp inside breaker is a no-no.
Often, for whatever reasons - someone will put larger fuses in the outside disconnect than what is called for.
When this happens the inside breaker is the only safety on the AC.
The problem is - for whatever reason - your inside breaker should not be tripping off.
It's likely that the AC may be on a inside breaker "that also has other things i.e. dryer, electric range or Refrigerator," and therefore any of these components 'including' the air conditioner could be causing the inside breaker to 'trip.'
One way to check this would be to 'un-plug' whatever else you had on the inside breaker - and then run your air conditioner and see if the breaker trips. Let's say you have the refrigerator and the air conditioner on the same inside breaker. You suspect the refrigerator is causing the inside breaker to trip - so you unplug it - and then turn on the air conditioner. "Now" it does not trip the inside breaker and assuming you have the proper fuses in the outside disconnect - you could safely say the air conditioner is ok - but - the refrigerator might be on the blink.
It's also possible that you just have too much on the inside breaker and you need to plug the refrigerator in to another outlet.
Still, if it was me - I think I would really think 'hard' about calling a Service Tech out - and let him/her diagnose the problem.
Hope this helps.
