When I plug the dehumidifier in it automatically turns on and runs. Even if I set it to the lowest level it runs. The bucket does not fill up. Also the coils show frost. Any suggestions?

Re: Frigidare Dehumidifier will not turn off

Pressure and temperature is directly related with refrigerants in the system. Ice building on part of the coils shows that the pressure inside the system is low and the system has lost some of its charge. Very low humidity with a low ambient temperature will also cause such a problem.

Direct drain

2 possibilities: #1The port that you plugged the hose onto need to be drilled so the water can come out and enter the hose. #2 The hose cannot be higher at ANY point than the bucket. Physics rules apply and the water will always fill the lowest point. Keep the hose low or raise the dehumidifier up.

How do you check compressor on LG LHD45EL

If you just want to make sure the compressor is running, turn it to the lowest humidity extraction level setting, which is 35%. If the air intake filter is clean, and the water bucket is empty, the compressor should turn ON, in less than a minute.

Hope this helped you and thanks for choosing FixYa.

Is there any way to run automatically. . . where when it reaches humid per cent it shuts off? Can you rig to run for x hrs. per day and then shut off and restart the next day?

Norman, once the unit reaches the extraction level you have it set for, the unit will turn OFF automatically. However, depending on the humidity level in your home, it may take several cycles of running and emptying the bucket until it reached. After that, it should turn OFF, once the level is reached. Then when the humidity level rises above the setting it's on, it will start up again.

Since your unit is a Manually Controlled unit, there's no safe way to "rig' it to run on with a timer. The plug in wall timers are not rated high enough to handle the load of the dehumidifiers operation. Trying to use one, would fry the timer and possibly the dehumidifier.

If you want all the features you mentioned, you will need to purchase a new electronically controlled dehumidifier.

Fedders a7dh45b2a*a-r dehumidifier shuts off before the bucket fills

Actually, it's probably doing what it should. Let me explain: Dehumidifiers run until they have lowered the humidity/moisture level to where you have the humidity extraction level set. At that point, the unit shuts OFF, until senses the humidity level has risen above where you set the level and it turns ON again. That doesn't mean the bucket will always be full when it shuts OFF. It may turn ON & OFF many times before the bucket is full. Watch for the Bucket Full Light to illuminate. That's when the bucket is FULL and needs to be emptied.

Hope this helped you understand how the unit works.

Lites up but does not run

First check the water collection bucket, to make sure it's properly seated and making contact with the safety switch. Also check the humidity level you have the unit set on. It may be to high for the humidity level in your house. Reset the humidity level to either minimum or if you have an LED screen 45%. Remember, the lower the setting, the more humidity will be removed.

To do an in home test of the unit, move it to a bathroom. Turn the unit ON and set the humidity level to it's lowest level. Turn the shower ON hot enough to generate steam. Do not turn the bathroom's exhaust fan on. As you exit the bathroom, close the door. Wait 15 to 20 minutes and turn the shower OFF. Allow the dehumidifier to run for several more minutes, before checking the water collection bucket for water. If you find any water in the bucket, it's working as it should. If not, it's time to replace the unit. Under most circumstances, I would suggest possibly repairing it. But, Fedders is out of business and replacement/repair parts are a scarce as hen's teeth.

Hope this helps you to further troubleshoot and solve the problem. Please let me know. Thanks.

How do i check if its working correctly

If you want to give it the ultimate in-home test. Put the dehumidifier in the bathroom with the door closed and a hot shower running, but do not turn on the bathroom exhaust fan. Set the dehumidifier's controls as low as possible and let it run for 20 minutes. After 20 minutes, return to the bathroom, turn the shower OFF and check the water collection bucket for water. The unit will probably be running anyway, when you return to the bathroom.

Remember, the lower the setting, the more the unit will run and collect water. Until it either reaches the humidity level you have it set for or the bucket is full and the unit automatically turns OFF

That's the best way to test a dehumidifier at home. Hope it helps you.
Please let me know.

My dehumidifier turns off immediately by the auto shut off. The bucket is empty and the filter is not very dirty. What could the problem be?

By "auto shut off", I assume it's not showing the bucket full light? If that's the case, it's probably one of two things. The bucket is not installed properly and is not triggering the safety trigger. In which case, reinstall the bucket, making sure it triggers the switch.

The other is that you may have the humidity level on the dehumidifier set to high. Remember, what- ever level (percentage) you set it on, that's the level the humidifier will maintain, Not remove. With that in mind, set the level at it's lowest setting. If you have an LCD screen it will probably be 45%. If it's a case of High or Minimum, set it on Minimum.

You also mentioned that "the filter is not very dirty", but you should clean that anyway. It's better to stay ahead on the cleaning, than having to play catchup on the cleaning.

Hope this helps you to solve the problem. Please let me know. Thanks.

My dehumidifier compressor runs and then shuts off, then runs and shuts off, continuously. The fan continues to run. It seems to be pulling water, though it's hard to tell how much because I have a...

Part of the problem may be that you have the humidity level set to high. The fan runs constantly to move the air around. When the unit senses a humidity level higher than what you have it set for, the compressor turns ON. Once it's ON, if the humidity level is short lived, it turns OFF.

Try setting the humidity level to the lowest possible setting. Usually, that 45%. If the humidity level in you home is higher than that, the compressor should turn ON and run until either the bucket is full or the humidity level reaches 45%. If this doesn't solve the problem, turn the Master ON/OFF Switch to OFF and unplug the unit from the wall outlet for 12-15 minutes. Plug the unit bakc in, turn the Master ON/OFF Switch to ON and set the humidity level at it's lowest setting. Allow the unit to run until it cuts OFF and check the bucket for water. Hopefully that 12-15 minute time out allowed the unit to reset itself.

Hope this helped you to troubleshoot and solve the problem. Please let me know. Thanks.

Runs and allows you to adjust settings, but no water ever fills bucket


First, make sure the humidistat isn't set too high by adjusting it to the lowest humidity setting and running it again. Next, test the dehumidifier by placing it in a closed bathroom with a hot shower running. If you don't see water collecting in the unit after several minutes, turn the unit off and clean all dehumidifier filters and coils. If, after adjusting the settings and cleaning the unit, you still don't see water collecting, you may have a refrigeration issue. This situation will have to be addressed by a qualified technician.

Take care.
