Hi David & Steve,
You guy's are great, I followed the Instructions by setting the Left side to Hi and Right side to Lo and similtaneously pushing the EC & Rest buttons for 5 seconds and bingo!! The Recirculate air button began to flash, the screen went blank and I was able to bring up the following codes by pressing the right auto button.

Eb 417 Eb 232
Eb 418 Eb 233
Eb 226 Eb 234
Eb 228 Eb 417
Eb 229 Eb 418
Eb 230 Eb FF

At this moment I am attempting to figure out what these codes translate to, I'm assuming they are all error codes.

Do these codes mean anything to you guy's, or should I pose that question another way, being that there are so many errors should I write it off and go in persuit of a re-manufactured unit, perhaps through Beckman Technologies.

Thanks Once again guys, you've made my evening.
