The warning light on my dnc65 dehumidifier is illuminated, it's out of warranty, how do i reset the warning light

Not sure. Might have a blown fuse or bad capacitor. Here are some DIY steps:

I got a 70qt (rerated to 40 qt if it is new) frigidaire
well rated, very popular, on AMZ. of course your application will determine what you need

Have a nice day

Good Afternoon Friend, that's a great question!

Typically the FILTER RESET light will illuminate after 250 hours of operation. To locate the filter, remove the bucket and the pull filter downwards. The filter can be clean by using clean water or vacuum cleaner extension hose. If you use clean water, please allow the filter to dry. Once you reinstalled the filter then replace the bucket. To extinguish the light simply press the FILTER button and your dehumidifier should resume normal operations. Remember it is best to clean your filter every two weeks based on normal operating conditions. Hope this helps! - Z

Hello Friend, thank you for allowing me to assist you!

Once the "BUCKET FULL" illuminate on your Frigidaire dehumidifier, soon after your appliance will shut down. Then you may remove the bucket by pressing the sides gently to unclip it and empty the collected water. After you reinstall the bucket, the float switch will reset. Hope this helps! - Z

Ignore the first comment, Desiccant dehumidifiers do not have Freon, or a compressor...

The warning light coming on after a few minutes could be one of a few things (but probably most likely due to overheating or the detection of something not right in the unit operation. Most likely faults include:

1) failure of main fan motor (this would cause eventual overheat)
2) failure of heater blower motor (this would cause an overheat)

3) clogged desiccant wheel (restricting air flow and causing overheat)


Generally the warning lights only come on if an overheat occurs, If the heater has failed these units usually continue to run, albeit cold, and with no water being extracted.

Another culprit could be the water level cut of switch being faulty.

Check that the wee magnet hasn't fallen out of the float.

Well although this is an old question, for the benefit of anyone who finds this in the future, the main reason for the main fan motor to stop working is due to the overheating of a tiny thermal fuse inside the motor itself. These fuses are one shot (meaning that if they trip, they will need replacing)

The good news is, that they cost about 99p to replace, the bad news is that you would need to strip down the unit and open up the motor in order to do that. This is a delicate operation and requires a steady hand, a soldering iron etc. the fuse you are looking for resembles a small resistor. usually located in a section of fibreglass insulation sleeve as the incoming wires connect to the motor windings. A fuse is easy to test using any multimeter a good fuse will show continuity and a dead fuse will show... nothing (open circuit) You would need to buy a replacement thermal fuse rated for the same temperature as the failed one (usually 115'C) and capable of passing mains voltage (240Vac) Cut out the old fuse and solder in the new one (it does not matter which way round it goes) Replace any sleeving and cable ties inside the motor and reassemble.

WARNING - do not attempt repair unless you are SURE you know what you are doing!!

Hi,
Here is a tip that I wrote about that problem...

May be power supply failure, faulty control panel or other problem. It may just need to be left unplugged overnight for reset.
