3 error codes

CodeMeaning
F1The F1 error code on a Frigidaire dehumidifier indicates a malfunction with the humidity sensor or its connection to the main control board. This failure prevents the unit from reading ambient moisture levels, causing the system to shut down for safety.

F2The control board is trying to read the humidity sensor and getting either no signal or a completely out-of-range reading back. The circuit looks open or shorted to the board, so it throws F2 and locks out the compressor until something valid comes through.

H1H1 means the control board is getting a dead or impossible signal from the humidity sensor, called a hygrostat. Either the sensor's internal circuit is fried, the connection's broken somewhere, or the board's input for that sensor has gone bad. Board sees the fault, kills the compressor to protect itself, throws the code.
