soap and softener dispenser door on LG series gets stuck?

Does anyone have problems with the LG Washer soap and softener dispenser drawer door getting stuck and unable to pull out to add the soap, etc.> It is on the top left hand side of the machine. thought it was the little trays catching on the top. doesnt seem to be the case. any ideas?
I had great luck with this forum to repair the Hall Sensor last year. Hope this gives me a solution again.
