Hi Jremy,

I'd replace the expansion valve as a matter of course and probably the Dryer also, unless it's fresh.

With the Expansion Valve out you can blow compressed air thru the system to check for blockage. If you see debris in the EV intake, it means the Dryer has gone bad and allowed desecant to permeate the system. In that case a chemical flush would be in order, although at this stage a chemical flush is also a good idea..
