dehumidifier repair: diagnose; repair leak; test; try;

Fixed several of them. Takes some skill with brazing. Have had 5 different brands that have lost charge. Must braze in service port on low side, find fix leak if possible, evacuate, and very important, “weigh in the charge”. R410a must be charged as a liquid. Takes LOTS of tools and equipment but if your in the business, not difficult. Not a DIY thing due to equipment and brazing skills as demonstrated in this video.

Garden hoses and dehumidifiers... Two things one never needs to buy if a fixer. Garden hoses only need new brass barb fittings -- no worm-drive hose clamps, use flush-fitting wire clamps (see the ClampTite tool and/or the associated DIY-built clones). The last dehumidifier I dragged home on trash day was a very nice Whirlpool example. The compressor would run even if the unit was switched off via the electronic control panel. The compressor would run until thermal overload. Okay, I dove into the electronic controller board and discovered the compressor relay was stuck in the "on" position. The control side of the relay was being commanded correctly from the electronic controller board. With a brand new relay sourced off eBay, I desolered off the old one and installed the new one. The thing now works like a dream! Actually, better than a dream since the dehumidifier was free and fixed with an hour or two of diagnostic time and fifteen minutes of electronic soldering.

Great video, how many pounds of 410a does a dehumidifier take ? Thanks

[@rob12449]

Thank you. I do not know how much but do know it is a very small amount, probably a few ounces.

I'm ready to do the same thing. Thanks

My first dehumidifier repair. Since this experience I have acquired another and am in the process of diagnosing it. I found rust at the low side tube right at the compressor. It has slight frosting when it runs so probably a bit more refrigerant remains compared to first experience.

410a does hurt the environment according to the EPA

[@rob12449]

well it is said to not damage the ozone but they say it is a greenhouse gas, so it is still not legal to just release it.

[@jakobporterz3211]

410a? 134a? Both have different boiling point.

[@rob12449]

it was 410a.
