20 Most Recent Comfort-Aire BHD-651 Dehumidifier Questions & Answers


Don't know your model specifically, but the float is usually at the top of your water tank and activates the system to shut down by popping up when the tank is full. With some tanks you can actually reach in and sort of clean off the float. Jelly-like stuff can build up on the float after a number of years. Cleaning it off wouldn't hurt.

Two things generally cause this problem. If your unit has a Float Valve inside the bucket, it's stuck in the 'Up' position, which under normal conditions, indicates to the unit, that the bucket is FULL. If you don't have that, then when the bucket was last inserted into the bucket holder, it did not trip the bucket removal safety switch. Remove the bucket and reinstall it, making sure that it fits squarely into the hole from top to bottom. Leave the unit ON when you do this, because if you do it correctly, the unit will automatically start and run. Also, be sure that humidity extraction level is set on 32 - 35 %.

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

When you powered down the unit, did you just turn if OFF using the controls on the unit Or did you unplug it entirely? If you didn't unplug it, it won't reset itself. Leave it unplugged for at least 30 minutes. As far as the blinking bucket full light is concerned ... It's possible that the bucket is slightly out of kilter and is only making partial contact with the safety switch. Especially if it's sitting on uneven soil or when the bucket get partially full the weight of the bucket is pulling it out of kilter because it's sitting on soil, rather than a hard floor. If nothing else, place it on a 1/2" piece of plywood or OSB and level it.

To be totally candid, I have some concerns about leaving a dehumidifier running, unattended in the crawl space of a house. There's to many things that could go wrong that would have disastrous results.

Start with the outlet they are plugged into - any power there?
The only solution I can suggest is to take it apart and check the wiring for any burned or shorted wires.
Also check the control circuit board - most have a small glass tube fuse on them. It is possible it was blown when the house was hit.
