Dehumidifier not collecting water

I probably have 1000 hours of propane in a 30 pint per day r410 dehumidifier and i did a lot of screwing with it so yeah its got a lot of water in it. At one point it was a water cooled air conditioner and actually worked better, with 120F water draining down the sink  than a 1 ton portable ac unit did in the same conditions.

I usually cut the capillary tube in half when converting to propane.

The rotary piston compressors are far more forgiving than scrolls.

You can buy the shrader stubs for like 1$ each and you can braze 3/8 copper with a regular propane torch.

Propane works great as a refrigerant and if it wasn't for the fire hazard would probably be standard in home appliances. It's dirt cheap. B.T.W., At the G.E. locomotive factory in Erie Pa we have an old G.E. 'Monitor Top' refrigerator that was originally in the factory museum. I am told it still actually works. It does use some strange blend of refrigerant. While running service calls for my father's T.V. repair shop I was out on a call to a dairy farm. They had a family room in the basement of the farm house and there sitting in the corner was an old G.E. monitor top unit still in running condition keeping soda pop and beer cold!!! Amazing, it was the first one I had ever seen in real life.

Friend of mine has an 80 yr old fridge with possibly, sulphur dioxide as a refridgerant. It broke after the most recent flood.
 Beachfront cabin that flooded once every 5 to 10 years, camano island in wa state.

That fridge seemed to have magical properties. Nothing went bad in it. Probably because it was a uniform 34F

The compressor was in the bottom and it survived probably a dozen baths of 6inches to 2 feet of salt water.

Hey, based on what you've described, it really sounds like your dehumidifier might have a refrigerant leak.  The compressor getting hot and the coils not changing temperature are pretty strong signs of that.

I hate to say it, but it's probably not worth trying to fix. These kinds of leaks are a pain to deal with, and even if you could find someone to recharge it, the problem would likely just come back. Plus, with the age of the unit, you might end up spending more on repairs than it's worth.

I know it stinks to lose a perfectly good appliance, but sometimes it's just not worth the hassle.  You might be better off just biting the bullet and getting a new one.  The good news is that newer models are way more energy-efficient, so you might even save some money on your electric bill in the long run!
