Dehumidifier blows cold air and doesn't collect water

I have a Heat Controller model BHD-501-G that started blowing cold air, not collecting water, but the compressor gets super hot. I'm assuming that this might be worthless at this point, but any help you could give me would be much appreciated.

Do you have good airflow out of the unit ?
Is the air coming out colder than the room temperature or the same ?

A dehumidifier is basically an air conditioner. The air enters the front thru a foam filter and contacts the cold evaporator. The humid air condenses on the evaporator coil and the condensate runs down to the catch pan. The air continues thru the unit and blows thru the condensor coil cooling the hot refrigerant and the compressor.

The airflow, is great. It seems to be coming out slightly colder than room temperature. Filter is clean. I've got a fairly good knowledge of air conditioners, refrigerators, etc., which is why I'm kind of baffled here. There was never an leakage from the bottom. I use a multimeter and a lot of other tools regularly, but I'm not sure where to go from here...

Remove the front panel and filter. Feel the evaporator coil.
If it's not ice cold you probably have a refrigerant leak.

The copper line on the side that coils around 5 times and goes into the front coils is cold and condensing, but that's it. Actually, the "L" part is freezing. If you need pics, let me know, I'll have more time tomorrow.

That sounds like the supply line to the coil.
If the line is getting cold but not the coil then it definitely sounds low on refrigerant.
Basically time for a new one.

Yeah, I kind of figured. Luckily, it's actually my backup. Thanks a lot for the help! I'll visit and refer the site in the future.
