Fridge is GE Profile PGCS1RKZHSS
Both the vertical articulating mullion between the fridge doors and the horizontal mullion between the double freezer drawers have a lot of moisture build up.They are always ice cold. I've tested both mullions for ohms and both are way out of spec. I tried testing the voltage for the mullion between the freezer drawers - manual says to check at mainboard J7-9 to J12 for 13.6v - it's showing 0volts AC .. can this be due to the ohms being off the charts (reading ~1,876ohms when it should be 827ohms)? Likewise, the articulating mullion should read 24ohms but read over 800ohms.
I tested the humidity sensor and its voltage is within range, but i disconnected it and wait 20 mins per the instructions - mullions were still ice cold.
I replaced the mainboard 9 months ago due to ice maker issues, i dont believe it has an issue - was just concerned I wasn't getting any voltage from the mainboard to the mullions for another reason other than the mullions being bad. The over-temp thermostat could in theory kill the voltage if it is being tripped, but i just changed that last week...and the freezer/fridge get to temp and stay.
