Default Sanyo 4912 Kegerator problems

A buddy of mine purchased a 4912 kegerator setup from a friend a few months ago. It is drilled through the top. Beer lines, in a PVC pipe surrounded by insulation, run up into a ceramic draft tower on top of the bar. The CO2 tank sits outside and the gas line also runs out of the top. A small project box fan pumps cold fridge air up along the beer lines and into the tower to keep the lines cold.

The problem is that it cannot get the beer even remotely cold enough. The compressor runs constantly. The back freezes up, so I think the coolant is ok. I took the seal off and made sure it was completely held on by the whiteboard. I also sealed up any gaps in the PVC pipe and/or from the top of the fridge with foam and insulation tape. If I put a flashlight inside the fridge at night, I cannot see any light escaping. Right now the corny keg is sitting at 53 degrees. There is a Johnson controller set to 39 degrees. The temp probe is in a small bottle of freezer goo.

Any ideas? I thought about a small PC fan to recirculate the air, but it seems the problem is bigger than that since the unit does not even get remotely cold enough.

How long has the keg been in there? Does the compressor ever kick off?

You say you have a "small project box fan pumps cold fridge air up along the beer lines and into the tower to keep the lines cold".
Do you have a cooling air line set up to return the tower cooling air? Also, where is temp probe placed that controls the refrigeration unit? If it is the standard Sanyo thermostat controlling the unit, I think it might be setup or adjusted wrong.

I have 2 of the refers and do not have a single problem with them.

Please describe your exact set up. Perhaps we can help and advise.

He mentioned he's using an external temp control:

Even with no keg in there it behaves that way. It's been weeks.

You know I don't remember seeing a return line. I had wondered about that as well.

I missed that.

Ok: Right there this presents a serious problem. Now I understand why it is freeing up. The next issue is where is the temp probe placed? And then: Is there a return path for the cooling air being blown into the tower?

Well when I've monitored my temps closely I only get a temp drop of about 2ºF per hour, so if the corny is room temp it would take a while to chill. If it turns off at all before the beer reaches temp perhaps your probe setup is not matching your actual beer temp? Maybe try dropping the temp on the Johnson to 34º and tape the probe to the side of the corny.

Oh also, make sure the factory thermostat is turned up to max so the Johnson has full control.
