SOURCE: Really thick ice on back of dehumidifier

It is now frozen because the humidistat, which controls the on/off cycle, is starting to age and forgetting to turn off the dehumidifier. Try removing the humidistat and, using compressed air, blow it out thoroughly of any dust. Then spray the rotary control area, including electrical parts, with WD-40. Then, blow dry again with the compressor and try again.

I dropped the water bucket by accident on the dehumidifier, and I have the same problem. Here what I found :
First, remove the water bucket and find the circuit diagram, it is very useful.

E1 code is related to the room humidity sensor, E2 code is related to the room temperature sensor and E3 code is related to the safety thermistor sensor. If you have one of these error code displayed, you will probably have to replace the sensor.

The humidity and temp sensors are located on the same board. To access it, remove the water bucket and you will see the 2 screws holding the front panel. Remove the screws, then gently prayed the front panel. Be careful, there is two plastic clip on the top of the panel and they are really easy to break. The board is located at the top right, under the cover. The safety thermistor is located on a pipe on the right side of the dehumidifier.

The biggest reason is plugged filter...or te coil bhind the filter is plugged. Then you get into whether the compressor itself is running or not. Just because the fan is running does not mean the compressor is

Why compressor comes on for a second then shuts off


Good Morning Friend,

I understand that the compressor on your Frigidaire dehumidifier, model# FAD504TDD, comes on for a second and then shuts off. First, make sure that when you are first turning your dehumidifier on that you put it in continuous mode. After about 3 days of continuous mode, set your appliance to the humidity level you would like. Secondly, the "Compressor" circuit has an automatic 3 minute time delayed start if the unit is turned off and on quickly. This prevents overheating of the compressor and possible circuit breaker tripping. Thirdly, make sure the tank is fitted correctly otherwise your dehumidifier will not turn on. Lastly, make sure your dehumidifier has sufficient clearance to operate. There should be a minimum of 12 inches clearance around your dehumidifier. I ask that you please follow up with a comment on the post, at your convenience, to advise if further troubleshooting is needed or if your dehumidifier status has changed successfully. Hope this is helpful.

-Best Regards-
WP

The float is broken in our dehumidifier, is it repairable?


Is the float in the empty or full position?? If it is in the empty position, and the unit will run normally, then yes you can. The water will divert from the evap tray right into the hose. If it is stuck in the full position, and wont run because it thinks it's full, you will have to find a way to put and hold it in the empty position.

Is there a recall on this product? My compressor and fan run but no water is collected. I know other Amana dehumidifiers were recalled for fire risk due to compressor overheating so I took cover off and...


Your description indicates a loss of refrigerant in the dehumidifier. The metal heat exchanger above the water collector should become cold when the compressor is running - if it does not, your dehumidifier likely has lost it's refrigerant charge. You will have to take it to a certified (refrigerant handling) technician to repair. It may make more sense to replace with a new dehumidifier.

Check the CPSC website for dehumidifier recalls. they will have details of the brands/models/serial numbers of recalled units.

My Goldstar Dehumidifier keeps cutting off even though its not full of water...any help?


A few things you could try are to make sure the float isn't covered in gunk and moving sticky-like, make sure air filters are clean and the compressor isn't overheating, and make sure the humidistat (probably a knob that says drier with arrows) isn't turning the machine off because it's reached the set level.

Full light comes on early


Most dehumidifiers rely on a float sitting in the pail to rise, turning off the switch. Check and see if the float moves clean and smooth, and is sitting in the pail rather than resting on it's brim.

There may be other safety switches, like a temperature sensor to turn it off if it runs the risk of freezing up or overheating.
