About 61 PSIG or 33 Degrees F. If you look at the gauge on your refrigeration manifold it will give you the numbers. What is Max, it changes with temperature and humidity and without very involved controls the absolute max will not be realized over the normal ambient operating range. Good Luck

, My KM30 Dehumidifier t'stat will not reognise ambient humidity properly. I placed the unit in my boat-steamy 80% humidity at 50%. it consistently turned itself off. Ok on 35 and Lo.


there is a sensor in the unit much like a temp sensor, (bullet shape) over time these do ware out and need to be replaced this tell the unit the temp so the unit knows humidity. it could also just need cleaning as a build up of damp then dry dust can cover the sensor.

Many of these consumer units use low grade copper for their refrigeration connections. The oil is a sure fire indicator of your seemingly correct diagnosis. Unless you have the proper refrigeration tools to repair and recharge the unit it may not be cost effective to try for a repair, as if this is the issue another leak is likely to occur. Many of these units come with 5 year compressor warranties though, so a quick check to make sure the leak is in the refrigerant piping and not on the compressor itself may be worthwhile. If your warranty has not run out it could be beneficial to find the exact source of the leak.

I have to agree with you. I don't see the need for the dehumidifier either. As the AC unit alone, does have some dehumidifying capability.

Your customer would be better served using an independent Low Temp dehumidifier in the basement. If that's the area they are trying to dehumidify because of dampness in the basement.. It certainly would be less costly to operate. But, any unit that is not a Low Temp unit won't work well in a basement.

I hope this helps and good luck convincing your customer of this.

Thanks for choosing FixYa.

Always empty no water basement is wet


these types of units are prone to losing their refrigerant/freon depending on which type the unit uses R22 freon or R134a/R12 refrigerant,now you can have it pressurized to find any leak,but it gets costly,as most of these units all makes will do this after 2-3 years

How to fill with gas my de longhi type DH 40 pints. It works with R 22


You shouldn't be using R22 anymore as it is being phased out and is bad for the environment. If it is not working, you might want to call in a pro to do the job. They'll have to hook up the dehumidifier to a manifold to essentially **** all the R22 out, ensure that there are no leaks, and replace it with a R22 substitute. It's going to take a few hours, so be prepared to pay $$$. The alternative is to bring it to a municipal recycling center or whoever that will accept it and buy a new one. You can't just throw it away.

Have a DDR583R with E-1 flashing blue, did not D-Humidify. Took unit to repair shop, 4 days later they called an said unit working fine, no repairs needed, cost 20.00. Came home, plugged unit in, works but...


If you're operating in area that where the ambient air temperature is between 40 & 60 degrees F. Like in a basement, where the air temp at floor level is cooler than at shoulder level, this could cause that reading. As dehumidifiers, unless they are Low temp models, will respond that way. Raising the unit up of the floor on to a sturdy table, counter top etc, that can handle the weight of the unit, plus a full bucket of water, will generally solve that problem.

If the unit, in all other facets is working as it should, do worry about it. If a sensor had gone bad and wasn't replaced, the unit wouldn't function at all. Also, keep in mind, that the repair shop's environment was different than yours.

One-year old LG humidifier (LD450EAL) runs but no water is being extracted from the air - the hose outlet is dry. The hose is connected properly, and the compressor sounds like it's running, not just...


Alan, it may simply be a case of several things, that can easily corrected at home.

1. The Humidity Extraction Level is set to High. Lower it to 32-35%.

2. Air intake filter is dirty or clogged. Remove, inspect the filter and clean if necessary. It it's a
Washable Filter, allow it to thoroughly dry before reinstalling it.

3. Obstructed Air Flow. A minimum of 12" to 18" clear air around the entire unit, must be
maintained.

4. The ambient air temperature at floor level is between 40 - 60 degrees F. This is particularly true in
basement applications. The air temp at floor level is colder than the air temp at shoulder level.
Dehumidifiers don't work well in that temperature range (Unless, it's a Low Temp model). Raise
the unit up off the floor on to a sturdy table, counter top, etc, that can handle the weight of the
unit, plus a full tank of water.

If you troubleshoot the 4 things listed above, it may quickly solve the problem. Please let me know. Thanks.

You must be qualified and licensed to work on a sealed system with R22 And it's not the PSI that matters. If the evaporator is leaking, get a new dehumidifier.

Temp and humidity levels are not correct


It sounds as if the temperature sensor probe is touching the cold coil inside. The sensor is located in the incoming airflow, in front of the cold coil. It must not touch the coil. This should be visible with the cover off. You can gently bent the sensor away fron the coil, 1/4-1/2" of clearance is plenty.

You need to have the r22 charged... As stated above, if its low on r22 then it will ice up... no dehumidifier should ice up.... call a repair guy or better yet, buy another one... good luck.
