SDML Damper P/N 090377A0013

[mimarch]

We had a lightening strike just outside our house, Th next time I tried to use the A/C the fan would not work. In checking I found the BMPlus 2000 control panel was not working, I replaced it with a BMPlus3000 and the system is now working but the dampoers will not remain steady. Power is correct at the terminals but the dampers keep cycling from open to close and the damper open/close lights do not work. i have two zones each with a SDML P/N 090377A0013 damper, both are doing the same thing. I suspect it was the lightening strike, can I replace the circuit boards in the dampers or do I have to buy all new?

You do not have to replace the entire damper. You can replace just the motor actuator. The part number is Model MA-SMDL.
