Hello, can anyone tell me if there is a way to speed up the defrost cycle on an older York heatpump with the york guard module. I don't work on very many york units, so if there is a way to do this, I never learned it.

I should be a little more specific. when the unit goes into defrost, it kicks out on a code 2, which is liquid line pressure exceeds 400 lbs. I believe this unit was overcharged. I recovered 2.0 lbs of r-22. but I need to be able to initiate a defrost cycle to make sure the pressure does not go too high again I was hoping to find a way to put it into a test mode without having an analyzer tool.
