Comfort-Aire BHD-651 Dehumidifier - Answered Questions & Fixed issues
Where is the float
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.

The unit is showing "full
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.

UNIT ICED UP. TEMP. IN CRAWL SPACE ABOVE 60
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.

Comfort-aire BHD-651 Dehumidifier broken after power outage
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.

Bucket full light will not
The bucket full light is controlled by a manual 'float' switch in the bucket itself
-when the water level rises...it lifts the float ...turns on the light and does not allow the unit to operate because it believes it is full.
It is very common for the 'float' to gets misaligned, hung-up, etc. when you remove and re-insert the bucket. Sometimes the 'chain' gets twisted, turned...which does not allow the float to ...float...rather it is 'hung-up' which indicates it is 'full'...when in fact it is clearly not.
To check this:
- remove bucket from unit
- look into the top of the bucket opening to locate the 'float'...generally 2" round plastic ball on a shaft, (or chain)
- softly cup the float in order to lift this up...with the unit stilll plugged in...to see if the light goes off...this is very likely
- then be sure that the float mechanism is able to freely 'float' in the space....i.e. you are trying to simulate the impact of rising water levels in the bucket
- as it rises (in your hand the machine will turn off/light on...as it drops....the light shuts off, allowing the machine to run (when humidity levels demand it)
- then re-install the bucket....being very careful to lift the float, while you insert it...there is generally a little nack to it...but you quickly learn how to do it easily (I just reach into the space...cup the float...put the bucket on an angle...slide it in....release the float into the bucket...(remove hand)...then finish pushing the bucket into place
-hope this helps

Fan does not come on
I've seen abunch of these. The fan motor has a fuse wound into the windings. It cannot be replaced you need a new fan motor. The motors seem to run hot normally, leading to a short lifespan.
I suggest buying a better brand unit.
