good luck and keep us updated

A blocked drain wont necassarily cause icing. Though it can cause fluid retention. In my case it was simply a case of the system being over efficient and cooling below freezing at the evap. That combined with high humidity led to a complete blockage until thawed.
Just Got it, Give me time!
