A:Answer I contacted Fridgidaire today via the live chat on their website regarding my dehumidifier that was displaying this error code. It was purchased in 7/2018 and is now 12/2019, so I thought that the 1-year warranty was expired and that they would not be able to do anything. I decided to try anyways, and they stated that this issue is a part of the unit's sealed system, which is actually covered for 5 years! I have to send them a few photos and some additional information, but they will be sending me a replacement unit. I recommend trying this before modifying any of the sensors or wiring internally on your own. (I'm a low voltage electronics tech, so that would have been my next step.. Contact them first!)
