My Frigidaire dehumidifier model FDL70S1has an error code "A5" My coils keep freezing up as well with heavy ice. It has worked fine in the same spot in the basement for two years until last week....
All most all dehumidifiers have a defrost cycle to take care of this problem. However, yours is either not working or the air intake filter is clogged, which makes the unit strain to keep up. Turn the Master ON/OFF Switch to OFF and unplug the unit, before attempting to remove the filter. Allow the unit to thaw while it's unplugged. Once it's completely thawed, plug the unit back in, turn the Master ON/OFF Switch to ON and set your controls as you normally do. Within in an hour or two, you will know if this solved the problem. Also, keep in mind, dehumidifiers are designed only to work in temperatures above 41 degrees. If it's below that where you have the unit, that will cause it to freeze up.
With all that said, what you're seeing as the Error Code is in fact, AS (the 'S' looks a lot like a 5 on the LED screen) It indicates a Sensor Failure. In your case, it's more than likely the Defrost Cycle Sensor. The Owners Manual says "Contact your local Authorized Frigidaire Service Center, if this happens. I'm hoping that cleaning the filter (if needed) and allowing the unit to reset itself (while it's OFF & Unplugged) will solve the problem. But, it may only be a band aide fix.
Hope this helped you.
