2008 Frigidaire 50 pint Dehumidifier from Lowes

Will the dehumidifier restart after a power failure or does it have to be reprogramed and restarted. My old one restarts at desired settings. We spend winter in FL. and leave dehumidifier run all winter at desired settings.
We intend to buy a new one. Thank you.

You can test it out by disconnecting the power cord, wait five minutes and plug it back in. If it retains the original settings you are good to go. If you are wondering before purchasing a new unit ask before you buy.

Is it possible to buy a portable dehumidifier which will automatically restart and function after a temporary power outage? What do you ask for?

Hello William, thank you for your post!
I understand that you would like to have a dehumidifier that restarts after a power outage. I have reviewed the available models for Frigidaire and show that feature is not available. You may want to speak with additional manufacturers for that feature. I hope this information is helpful to you. -Matt

After unplugging, we moved the system across the room and can"t get it to come back on.

Unplug it for 5 minutes then restart it. A compressor needs 2 minutes to equalize pressures before attempting to restart.
Check that your outlet has power.

I have two of these dehumidifiers. They won't go on automatically. I don't understand the settings. One of them won't stay on at all. It runs and then shuts off.

As per your problem, that the dehumidifier shuts offautomatically - If yourdehumidifier froze, the compressor will shut off automatically. Allow the iceto melt before emptying the tank and restart the dehumidifier. Hope this will help you. Good Luck.

My dehumidifier doesnt take any moisture out of the room let it run for 24 hours and buckets empty can you help

Not sure if you have set the level of operation correctly. It may be set to low.
In addition, have you noticed any frost or icing on the coils of the unit? If so, it's frozen up and you will have to allow it to thaw out completely, before restarting it. Also, the air temperature where you have the humidifier can affect it's operation. Especially, if the temperature is below 41 degrees. In addition, if the filter on the back of the unit is dirty, that will definitely affect the proper operation of the unit.

In case you have misplaced your Owners Manual, I have included a link to it. You can download and print it for future reference, if you so desire.

Hope all this helps you solve the problem. If all else fails, you can always contact Frigidaire Technical Service at 800-44-4944.

What you think it means is exactly what it does mean. When a running unit is shut off it should not be restarted until the system pressures have had time to balance out so the compressor can restart without difficulty.

Does this dehumidifier auto restart after power interuption?

Hey dehumidiguy,

Have you considered an appropriately rated UPS unit for ridethrough ? American Power Conversion offers a sizing calculator on their website that will tell you the size UPS needed to provide ridethrough based on the load size and the amount of time you need it to continue operating.

Good luck,
