First step is to measure the resistance of the coupler to see if it's the coupler or the board. You should get around 5-7 ohms across the coupler when it's unplugged.

Hi John. I'm having this same problem with my UP LC+ GP38 (6-82828). The front electro-coupler will not operate/open. I can check the resistance as you mention. Do you know what voltage is used to operate the couplers? AC or DC? I was planning to disconnect the front coupler and try to test it separately, to confirm if it is a problem with the coupler, or the control board.

I see replacement electro-couplers from Lionel are $14. (part# 6308821550) I didn't want to order a new coupler until I confirmed the problem is with the coupler itself.
