At this time every year I turn on my Fedders A7DH45B2A Dehumidifier in my finished basement. I turned it on the other day and it will not extract water. I have a humidity meter in one bedroom it is 67%. I have another meter in the main living area and it reads around 75%. I checked the filter and it was dirty and I cleaned it. This does not solve the problem. I read the soloution on the previous page and it says, refrigerant needs to be injected into the compressor. How does this refigerant escape? with the compressor losing refrigerant, is this a common problem? I'm disappointed that this happened. Isn't going to cost more than the dehumidifier's worth to have it serviced? Thanks, Bob

Bob, the unit may not need to be recharged. I may simply be a matter of the humidity extraction level on the unit is set to high. Try lowering the extraction level to 35% or if your dehumidifier doesn't have a LED screen, set to maximum. In addition, be sure that the unit has at least a minimum of 12" clear air space all around the unit.
As far as recharging is concerned, it's like recharging the air conditioner on your car. But, in this case, your mechanic can't or won't recharge the dehumidifier. So before any recharging is done, I would like you to do this in home test.
Move the dehumidifier to the bathroom. Turn the shower on hot enough to generate steam. Do non turn on the bathroom's exhaust fan and close any open window(s) in the bathroom, Turn the dehumidifier ON and set the extraction level at 35%. As you exit the bathroom, close the door. Wait at least 15 to 20 minutes before returning to the bathroom. Ten turn the shower OFF and allow the unit to run an additional 5 minutes. Then check the water collection bucket for water. If you find any, the unit is working as it should. In which case, the humidity extraction level was originally set to high. If there are no signs of water, then the unit needs to be recharged with refrigerant. At that time, if there is a leak, it will be detected. As far as the cost of servicing and recharging is concerned, depending on where you live, it could be up to $100.00 or less.
Hope this helped you troubleshoot and solve the problem. Please let me know. Thanks.
