My LG refigerator no longer blows cold air in the refrigerator or freezer compartments. You can hear the compressor click ever 5-10 minutes or so but there is no cold air. Sometimes you can feel room temperature air blow into the fridge but most of the time you get nothing. The front electronics appear to be in normal working order. The fan blowing across the coils works. The coils are clean.
The fridge was recently transported to my house on its side (only on its side for 15-20 minutes) but the problem began before we received it where it was upright for a long time.

Any ideas as to how this can be fixed?

thanks in advance LG LRSC26922SW

I've left it unplugged for over 24 hours and it had no effect. any other ideas? the prior owner had it unplugged for an extended period of time (weeks, maybe a few months). don't know if that is helpful but that's all i know.

I replaced the PTC assembly and the refrigerator is behaving the same way it did before. any other ideas?

Do you have a wiring diagram for this refrigerator? I want to be sure I have everything connected properly.

Here's an update to my situation. I purchased the PTC Assembly and Overload Relay as recommended in this thread (the PTC Assembly included an Overload Relay, not sure why an additional relay was recommended, oh well). The replacement part did not match up exactly with the original but I installed it anyway and it didn't fix the problem.

The original PTC assembly had some electrical 'burn' marks on it, kind of like a popped fuse and it rattled. I opened the PTC assembly and noticed a ceramic-like disc that had a couple of pieces broken off it. This disc was inserted in the middle of the PTC assembly and an electrical contact touched each side of this disc. I'm not an electrician but it is obvious that this disc is some sort of conductor and my refrigerator stopped working because the part of the disc that broke was touching one of the electrical contacts inside the assembly.

So just for kicks I pulled the ceramic disc out, rotated it about 180 degrees and put it back in the assembly so that the electrical contacts now touch both sides of the disc. I wish I took some pictures because I'm sure my descriptions are terrible :).

I put the PTC assembly back into the fridge, plugged it in and viola, everything works!

My quest now is to find an exact replacement PTC assembly for this fridge. I don't know what cause the original one to pop but I don't want to be dead in the water if it happens again.
