Question about LG Dehumidifiers
If the switch by passed but still the problem is same, that means the problem is with the control board.Its not detecting the bucket.--------- Reconnect the switch as it was and then try this:------
Look inside where the bucket goes in at the top right hand side is the bucket switch. Hold it in and start the unit. If it runs the arm on, the switch must be bent SLIGHTLY until it makes contact with the button and the lite goes out with the bucket in.-------
Also check the float in the bucket.If the float in bucket is stuck then it will always detect water as full. and red light will flash.The float moves and actuates the switch.But if float is not moving the switch will not actuate and dehumidifier will not get command that water is empty.But if float is not stuck and its moving freely then its the switch.The switch to which the float actuates.That switch is got faulty.The switch can be manually depressed and checked.If still the red light flashing then switch is confirm faulty.-----------
Also check if fan is running or not.Also do you hear any humming.As you mentioned it starts then shuts of, this clears that fan runs.But still re check and confirm it.------------
If the fan hums but does not turn, or turns slowly, the motor needs to be replaced. If the fan won't move, you may have a bad switch . ----------But in your case,you mentioned that fan runs for 2 seconds then shuts down,this indicates that fan switch is not short,its the fan controlling motor,that is got weak and it needs to be replaced.Also check the fan motor connection to main board.If there is a short is wires between fan motor and main board,then this will overheat the motor,as soon as you turn on the dehumidifier ,in that case,if there is short wire the new external wire has to be connected,but if wires look fine then its motor ,that is to be replaced. To replace a bad fan motor, unplug the machine and disconnect the fan wires from the switch panel. You may have to pry apart a plug, use needle-nose pliers to pull the connectors off the switch, or unscrew the connectors.Remove the old motor from its housing, using a Phillips screwdriver or a nut driver and socket.Remove the fan blade from the motor.and in the same way re fit the new replacement motor and connect its connections as it were connected before.---------
If the temperature in the room is lower than the setting on the dehumidifier, the unit will not run a cycle. The unit has a setting of no lower than 65°F. If you have the home thermostat set lower, the unit will not run a humidity control cycle. Set the thermostat higher on the home air unit that supplies the air conditioning. Set the dehumidifier to a lower setting if you are running the air conditioners during the warmer seasons.---------- This will help.Thanks.Helpmech.
