Peter R State College , PA March 30, 2016 Appliance: Frigidaire Room Dehumidifier FDL70S1A Frigidaire Dehumidifier Fdl70s1a: Had an as or a5 code on a frigidaire 70 pt dehumidifier which is the humidity sensor. How to replace Ddr Humidity Sensor. Located part at Appliancepartspro and ordered it. It came quickly and I installed in. Dehumidifier now works fine! Fridgaire told me to buy a new dehumidifier as if would be too expensive to fix. LOL! They didn't even have the part available. 53 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
