Question about Bionaire BDQ24 Quietech Dehumidifier

Does this dehumidifier auto restart after power interuption?

There are very short power interuptions where I live and I've discovered that certain pieces of gear (like a dehumidifier that runs in the background) should survive an interuption and restart afterward. I use lockout timers for gear like this, set to about 5 min, to prevent compressor damage from power flickering. But, of course, for this to work, the gear has to restart after outage. I've already got one dehumidifier, the Soleus 25pint/d, that does not auto restart... and it's a pain in the a__. Is the Bionaire 20pint/d the duhumidifier for me? Thanks Dave P.S. If anyone has any mods for making these dehumids survive an outage, please lemme know.

Thanks for a stab at it, JD. Well, sure, UPS units are an option. But realize that anything with a motor in it, i.e. a compressor, has a large current demand, particularly when it starts. Since a dehumidifier operates on a humidistat, there's no way to tell it 'you're operating on the UPS unit right now, so don't start up if you're stopped'. Starting the compressor on an UPS unit that won't support the draw will damage the compressor. UPS manufacturers specifically state these details in the fine print. But more to the point, I don't have to worry about this with my refrigerator, freezer, furnace, etc. It would be nice if manufacturers simply accomodated this rather common situation. I know that some do. It would be nice to have a list of all 25pint/d dehumids that restart after power failure. Also, it's also possible to restart, but on some manufacturer predetermined setting. So it would be nice to know which gear restarts after power failure and also resumes settings. It would also be nice to have a million dollars. All equal in likelihood.

But, thanks for the suggestion JD and have a great day,

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,

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

Dehumidifier runs continuously and displays higher than normal humidity levels.

Probably some glitch with the sensors. I recommend taking it to a service center.

My dehumidifier leaks and not shut off. The bucket is full, but the unit still runs and I notice water puddling under the unit and my rug is wet around the dehumidifier.

I don't have a Haier but I have a dehumidifier which has a float and when the float get to a certain point,it activates a switch for auto shutdown.If yours has the same setup,the switch is probably bad.
Good luck! Greg If not,let me know.

M7DH45B2A dehumidifier does not have auto restart when power goes

No. I went away for a week and set mine up in the tub. Power went out and it was off when I got home. You could buy a UPS ( unterruptable power supply) from the computer area in Walmart and hook it up to it. This would allow it to still run for a while and if the power came back on while it was still under battery power it would run like it was running. You can buy larger UPS units that would keep it running for longer amounts of time. Just an idea.

2008 Frigidaire 50 pint Dehumidifier from Lowes

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.
