Frigidaire Fridge model FRT18QRHW3

Had water in the fridge. Disconnected for 2 days. Opened the freezer panel inside, located the drain hole. I can see there is some type of filter in the drain hole, I am not sure if I need to remove it or not, does not appear to be dirt. Any ideas? I did put some hot water and it goes down slowly.

Also, the hole appears to lead to a spout inside the fridge, which leads to the drain pipe directly. But it seems glued to the back wall of the fridge and I don't want to pull it as I am afraid it will break. Maybe it is blocked there. Any ideas on this too? Thank you.

Answer this question I have this problem too

Most modern (last ~20 years) Frigidaire top mouth fridges drain defrost melt water through the drain hole in the fridge, though the divider into the control console in the fridge, where a funnel and spout direct it through the back wall. Common issue is a clog in that spout.

Yours is an older design that I haven't run into. The parts breakdown (linked below) shows both the air diffusor, and the dividers between the freezer and fridge compartments as replaceable (though discontinued) parts, so they must be removeable. I'd start by trying to remove the diffusor, looks like it might also catch the draining water.

Alternatively, you could try snaking a length of string trimmer line, 1/4" poly water line, or a trombone snake (available online for a few bucks) down the drain, or try some hydrogen peroxide in the drain to dislodge any organic material that could have accumulated

Or take a look at the lower end of the drain tube in the machine compartment near the compressor. There'll be some type of air seal, often just a length of corrogated tubing with an s-bend or a loop. Could also remove and check there for blockages, common on newer units

I also have trouble with the supplier's website linked above as the search function in that website doesn't seem to work to find model numbers parts list and when you have found the model number parts list (using a different entry method) to then find individual parts in the list being displayed.

Try this supplier to locate the part you need and then search online using the "wanted part number only" (part number shown for the part in the list) to find suppliers that suit you best.

Thank you. Part 17 appears to be the one with the drip hole, but it does not show the hole.

Isn't that the drain hole shown below the evaporator cooling fins in the 2nd image you posted in your question?

usually the drip hole is in the middle of the trough.

Most troughs sit below the evap unit and angle down from both sides to the middle so that the water all goes down the drain and doesn't sit in the trough.

Unfortunately I can't find any images of the part when searching online using the part number for the part.

Jayeff, yes, it is exactly that part (the drain hole shown below the evaporator cooling fins in the 2nd image).
