hi. damper stuck closed. i opened vanes with small screwdriver. put unit into diagnostics. on step 5 damper received 120 v ac. closed the damper vanes but would not open them with a constant 120v. problem is when unit is calling for cold the board is not sending 120 to damper. ff thermister was placed in ice water. reading was normal. i know the damper is bad but is the board bad also. freezer temps are good. compressor runs constantly. yhanks.
test thermister ff. diasnotics

Hi. It sounds like you just have a bad damper. It would not be probable for both parts to be faulty. The board will only send 120V to to the damper motor when it wants it to close or open, so you will only have 120V for a few seconds at at time. You will not have a constant 120V at the damper during normal operation.
