CH 67 Fault code CH 67

well 67%rh is considered low (70%rh is normal) units will produce much less water when tasked to operate in low moisture air , this is why all the new units have air temp ratings of 60Deg or less. but still the unit should try to go thru all the motions ,that you can easy verify , just by u watching /listening closely
set unit to work normally , listen 4 the fans inside to come on and a few moments later the compressor will come on if everything is working well , try adjusting the humidistat up to a value of say 80% listen 4 one fan and compressor to stop , this is all normal reset desired setting on humidistat
if unit fails any one of these simple tests it has an internal fault inside it and requires service

What the brand and model?

Bucket switch/float valve sticking? Take out the bucket and make sure the switch moves freely.

I decided to take a chance and order the new Sensor assembly $20.50 and install it in my LG LD651EBL Dehumidifier which was giving me ch 67 errors. Wala, it worked, the error code is gone and the dehumidifier is now working perfectly! Thanks

Error code 67 is an airflow problem. Either clogged filter or bad blower motor. Unplug unit remove bucket and feel for filter in front behind cover it drops down. Clean filter with water and reinsert. Plug unit in turn to "on", fan should begin to run, after 3-5 minutes compressor should start. If fan does not start it is bad and should be replaced.

After cleaning the filter, i had to unplug the unit to clear the ch 67 error code before the unit would run again.

CH 01 Indicates that water collection tank is full and needs to be removed & emptied. Turn the unit OFF and unplug it, before removing the bucket.

Had same erroe code in 2008. CH 01. Bucket Full light was flashing, but it was empty. Would not start. Called customer service and was advised it was most likely a compresser problem. In that compressoe was still in warranty took it to a lacal service center. Compressor was Ok, but had to replace Evap Thermister Board and Sensor. $120.00 in parts and $50.00 labor.
I am not an expert.
Good luck.

I have a Comfortaire BHD501 dehumidifier. A couple weeks ago I noticed ice building up on top of the unit,so I unplugged it to defrost. I plugged it back in and it worked until I noticed the "CH" "01" code. It would run a few seconds then shut off with that code showing. I took off the front of the unit and noticed rust on some of the metal parts. Then I took the cover off the circuit board for the front read out. I noticed corrosion on some of the solder points. When I looked closer at the plastic cover for the circuit board I noticed a small burn mark. The water from the melting ice must have run behind the cover and shorted out the circuitboard. At this point I don't know if new boards are available.

If you get a fault code CH 01, check the posting for that solution and see if it helps.
