Yesterday lightning made a mess of my roofing. It also damaged the
control board of my Bryant 383KAV.
The original board is a CES50110057. I had to replace several
components seven years ago. Without a schematic it was a hassle. Is a
Maybe it's time for a new board. I've found two places with
replacements for the original. The cheaper is $150 with shipping.
A third place has a CIB0110057 for $200 with shipping. It is a newer
design with diagnostic LEDs. That could be worthwhile but wouldn't help
much if I didn't have documentation to interpret the lights.
Which board should I get? Should I troubleshoot the one I have? Are
there good places to shop for boards online?
That's a good question. The system was off at the time of the strike,
and the chimney is on the opposite side of the house from the air
conditioner and furnace, so I hope the motors weren't wrecked. I could
jumper the inside blower but wouldn't know how to activiate the outdoor
unit without the board.
The board isn't scorched even slightly. The 3-amp fuse was blown.
Rather than risk my last 3-amp, I tried a 5, and the 25-volt
transformer's noise indicated overloading. One diode on the board is
broken, but that wouldn't be the only problem.
