What is the best way to free up a clog in the refrigerator drain line ??? Condensation tray fills up and drips inside and puddles on the floor and needs to be sopped up. I tried to run a flexible wire up from the bottom with no luck so now looking to see how others have managed to clear the drain.

ThanX all.

We have had a similar problem however the blockage was in the drip tray itself. The spout where the tray drains into the line becomes blocked. We removed the drip tray and cleared the blockage.

Pull the tray and line out, clean it then reinstall.

The tray has been out and cleaned. The water backs up in the small outlet that the drip tray drips into. Somewhere downstream there's a blockage in the hose causing the backup.

Do you not have an access door on the exterior for the refer? Both our trailers have full access to this line and the 2011 I needed to replace it due to it disintegrating.

Thanks Alan. I do have the access and need to look closer at that for a possible solution.

Now that I've looked for the drain line AND have an internet connection to reply I should note that the drain line seems to NOT be accessed through the refer access panel. I just don't see it. I did get a flexable but stiff wire and attempted to pass it up from the outlet with no luck. The drain is a semi-rigid white plastic tube exiting just forward of the wheels, drivers side, and seems to have a hard obstruction about 6-8" up the tube. I haven't yet, but plan to, try to blow it out with a compressor. So still blocked up here.

I believe your layout may be similar to mine. The white pex drain portion from the floor of the fridge compartment..starting from top...goes down to the top of the wheel well, makes a 90* turn to side of wheel where it makes another 90*, and another 90* turn to run a along the floor for about a foot, then makes another 90* turn through the floor and under the trailer. So the fact you hit a hard stop when probing from underneath is absolutely normal.
If you have access under the fridge pedestal (a drawer in my unit) remove it and you will see the drain tube.
If yours is pex, it can stand >50 psi of air pressure. I'd soak by pouring water from top. Let stand for quite a while and blow out with compressed air.
