Need Bryant Economizer help
Ok guys, thrown into a job via national accounts that have all Bryant units on the roof, no literature but they have economizer board with 2- 9 volt batteries on them, I turn the outdoor controller on the economizer down but the damper doesn't move, units won't heat or cool so I know it is an economizer issue.Anyone have troubleshooting literature on these and are the boards junk, I turned the damper worm gear by hand and it moves back to one position so motor moves.

The boards for those are so costly you should install new micrometal econmizers & forget fixing them.
Take your time & do it right!

Jumpering blue and gray on the economizer molex plug will get you mechanical cooling. The two 9 volt batteries were to shut the damper in the event of a power failure. I agree with the previous post. Too costly to repair.
Go to mechanical cooling(fan cycle,crankcase htr.,etc.) or reinvent the wheel.
