Condensation building around mullion. Ice build up in ice chute and bucket. If not getting any power to mullion what needs to be changed. Duct door heater as well. Any ideas or help would be appreciated.
Changed mullion, and fresh food door gaskets, and duct door heater.

HI. The power for the mullion heater and air duct heater come from the main control board(WR55X11098). Both door switches have to be closed for the the power to be sent to the heaters. Here is what the manual says about it.
Note: If the Energy Saver light is lit, then the heaters in the vertical and horizontal mullions are disabled. The heater operates on 13.6 VDC when both doors are closed. It is necessary to close the left side door and close the right side light switch to test for the operating voltage of 13.6 VDC. The resistance of the heater is approximately 4400 Ω.
It does not specify if the heaters are on all the time, if they operate off of a sensor, or run only when the unit runs.
So, if your not getting power to the mullion heater as long as your door switches are closed and working and there is not a wiring issue, I would replace the board. I have never seen these boards go bad for this issue personally.
