Heating, Air Conditioning, Fridge, HVAC/Lennox Gas Furnace Error codes - can I fix?

This information is helpful.  I got Lennox error code HE228 and started to trouble shoot.  Since the ambient temp was about -3F, and I have a fairly long, sloped, but nearly horizontal line running to the exterior, I suspected that ice in the exhaust line was part of the problem.  I drained some water and checked the vent, but could not find the ice without cutting the line.  I tested/exercised my pressure switch in this manner and got the unit running.  It appeared to be stuck, and this freed it up.  Once it was running a significant quantity of water drained from the pipe, making it clear that ice had been in the exhaust line.  Thanks for your assistance in resolving this problem.
