Runs but does not produce water


(1) Make sure that the fan is turning OK as dust often gums-up the bearings. (2) Make sure that the heat exchangers are not clogged with dust. If the main motor, the so-called pot, is running but no cooling results it could be

(A) The refrigerant has been lost. This is an extremely bad fault which makes the unit a basket-case. The reason being that even if a self-piercing filling point is added to recharge the unit with refrigerant, unless the leak is found and fixed the repair will be a nine day wonder.

(B) This fault is more likely and the fix is do-able. It is quite likely that the machine is stuck in its defrost cycle. Wiring problems, thermistor problems or relay problems are all possibilities. Some machines use an electric heater on the evaporator (the part that freezes-out moisture from the air) If the heater is stuck on, the evaporator will never become cold enough to work. The more usual defrosting method is Hot Gas Purge and if this is the type used there will be a special electrically operated valve in the refrigeration circuit. Often the default is to defrost-on-start-up so its easy to listen to the valve to see whether it clicks. Good luck!

Unit was charged w/ 10.6 OZ of R22 and don't seem to be working very good?


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

Will not defrost. Frosts up but not defrost properly.


The air intake filter may need cleaning. If it's dirty or clogged the unit has to strain to keep up. Also, if you're operating it in an area that's below 40 degrees, they have a tendency to frost over.

Turn the Master ON/OFF Control to OFF and unplug the unit. Allow it to thoroughly thaw. After it has thawed, remove the filter and clean it if necessary. It's also a good idea to access the refrigerant coils to wipe and clean them. After they're clean and dry, a light coating of WD40 would be an advantage.
Then, reassemble the humidifier's cabinet, plug it in and turn the Master ON/OFF Switch to ON. Set your humidity level about mid range (45%) and allow the unit to run for at least 1/2 hour before raising or lowering the humidity range.

Routine maintenance is important and will usually solve the problem. I hope that's the case for your dehumidifier.

Santa fe dehumidifier running but not producing any condensate. No ice forming on the coils and filter is clean.


You should check if the compressor is running. Your description makes it appear that the fan may be running and the compressor may not be running.

There are many things that can cause a compressor to cease running:

Open defrost thermostat
Bad run capacitor
Low refrigerant charge (caused by refrigerant leak)
Bad compressor relay
Bad compressor overload
Bad compressor motor

Other things to check:

If the fan switch is set to "on" and the humidity control is set to a high humidity level, the unit may appear to be running, but the compressor will not operate. Check the setting of your humidity control.

If the dehumidifier is operating in a room with a high temperature and a low dew point (very low relative humidity), it may be unable to remove any more moisture from the air.

If you are not comfortable troubleshooting the unit on your own, call the manufacturer service department at 1-800-533-7533, EXT 8459. They are very helpful.

Compressor runs continually and cooling coils ice up but it doesn't defrost.


probally has lost some charge on the refrigerant. Low charge will ice the coil. Unless you are operating this at low temperatures. The ones I have seen do not have a defrost on them

Running but not collecting water


your coils are probably frosted up. This can happen from the basement temperature being too cold if you dont have the automatic defrost type of dehumidifier, or it could be low on coolant from a pinhole that leaked it out. Mine did the same thing and I had to buy another one. I bought one thats operates down to 41 degrees Fahrenheit and it is an automatic defrost type. It works good for my basement because I have central air which makes the basement even cooler and harder to dehumidify without freezing the dehumidifier up.

Amana 30 (looks like dk25) unit runs but coils freeze up


Most dehumidifiers have a defrost mode in which the compressor is turned off to give time for the frozen water to melt. The freezing problem ocurrs when the unit is used in very cold weather. Check your manual to see if this unit comes with automatic defrost mode. If it does, it would appear that it is not operating correctly and you can request warranty service. If no defrost mode is available, then your only option is to heat up the room in order to use the dehumidifer within its limit of operation. Some units can operate as low as 36 F, but most units cannot go that low. Find out what your unit's specs are from the manufacturers web site.

Not working


Hate to tell you, but it may be a goner. Many units have a rectangular air filter that may be clogged, but I would still expect to see some moisture removal. Without exact model I'll have to be general,.... remove cover (front or back, depends on model) to see cooling coils. If the compressor is running, these coils should be wet or may have a light frost on them for a time. Not = refrigerant leak. (not economical to repair) If you see one small area of ice,... it's also a goner. If the compressor does not run you could have a bad compressor, a bad defrost control, or a bad control / humidistat. Other than the filter or possibly a fan motor, these unit are rarely economical to repair.

Will not shut off


My unit is a Fedders A7DH65B2A and your Maytag unit was made by Fedders and is just like mine w/ different label... I've purchased two of these units (one for me & one for my father-in-law) and they both quit pulling moisture from the air (but ran constantly) about 1 month past the 1yr warranty. My unit also acted really strange one day when the problem was occurring - it flashed on & off erratically and wouldn't power off unless I pulled the power cord. In short, I took it apart and found several issues and eventually figured out the chain of events that led to this: 1) The thermistor went bad and the unit could no longer sense when the evaporator coil started freezing up (normal situation that the unit should detect & then do a defrost cycle). As a result, the evaporator coil turned itself into a big chunk of ice (can see by removing the air filter and looking into that slot at the coil (looks like a radiator). 2) the big block of ice on the coil grew large enough to start making contact with part of the plastic housing above the evap coil that's used for the power control circuit board. The plastic in that area then got ice all over it and since it looks like a little tray, it will hold water (when the ice thaws) and then the power control board will be sitting in a puddle of water (or ice - either will cause malfuntions like not being able to turn the power off using the front panel switch). 3) the puddle of water in the power control board tray caused this circuit board to corrode (happens very quickly when the unit is plugged in since electricity accelerates this kind of thing...). So... a poor quality thermistor (this straps to the bottom right side of the copper pipe that loops out & back in to the evap coil and has a wire coming out of if) caused premature defrost circuit failure. This caused a big block of ice to form where it shouldn't be. The ice caused condensation/moisture/ice to form on/under the power control circuit board and corroded the circuit board and caused erratic power control issues. RepairClinic.com had a replacement sensor board (included all sensors - yes, the thermistor too...) so I purchased it (~$40) and used only the new thermistor off of it to plug into my original sensor board (and strapped it back to the evap coil w/ the chrome looking clip that was already there). Problem fixed! Well, almost... I did have to clean the corrosion off my power control board as well, but it survived luckily. After doing this to mine, my father-in-laws unit experienced similar symptoms. I did the same fix to his and presto... fixed. Cheap low quality thermistors on these units. I need to find a higher quality replacement thermistor before round 2 happens on each unit. Good luck!

Normal operation, the unit has sensed icing and is in the defrost mode (compressor off and fan on high). When the ice melts normal operation will resume.
