3850A20500J no power to control panel - LG Dehumidifiers

Question edited, toss in a load of CAPS.

The capacitor is likely to have failed internally. It can still produce voltage. Or the transformer that supplies power has failed.

No one else has recorded this issue

..

as there are two control boards in ac units ( split systems) and one in a window unit
it could be the inside board ( they do not suffer power surges to well or vermin infestations at all )
before you waste more money I suggest that you get a technician in to determine the fault and if parts are readily available.

Hey friend, I appreciate your inquiry!

If your Frigidaire dehumidifier is not powering on it could be an issue within the control panel or power cord. I see you checked the outlet it was plugged into, I would test your appliance in another outlet. If you still receive the same response it sounds like it could be a problem within the panel or power cord. Is your appliance under warranty? If so, I would advise you to reach out to the manufacturer to determine any potential remedy. -Matt

My guess is something got into the controls and has shorted the power to the fan. Take panels off of the unit and vacuum, and wipe or brush, with soft brush, as much as you can. Do not use any liquids in cleaning. Hope this works for you.

I don't think it's a thermistor problem, as previous respondents have suggested. I have one of these units. The control panel has been nothing but trouble. The Power button works, but the Fan Speed button is stuck on High. The Humidity Up/Down buttons only work sporadically. Sometimes they work if I keep punching them. There doesn't seem to be any rhyme or reason as to when they work and when they don't. I think they're just cheap parts that have failed prematurely.

Hi,
Thanks qrx1llb3 for the help!
After carefully removing the plastic covers (yes, u need to remove both, I removed first the back one then the front one by pulling up, then disconnect the cable that joins the panel on the front cover with the electronic board on the upper right area) I found the electronic board with the blown up fuse. My was under a blue plastic cover. I'll try to replace it and see what happens! thanks for the help! :)

power button does nor work

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.

You need to have the r22 charged... As stated above, if its low on r22 then it will ice up... no dehumidifier should ice up.... call a repair guy or better yet, buy another one... good luck.

Independent of the bucket switch, the control panel should light when the unit is plugged into a powered receptacle and the on/off switch is depressed. The problem is likely the 12 amp. fuse located inside of the unit.
