6601A20013T Genuine Float Switch Assembly for LG Air Conditioners, Condensate Water Level Float Switch, LG Air Con Switch

Part 6601A20013T is a genuine LG float switch assembly, which we list for LG air conditioners. In air conditioning, a float switch watches the condensate water level in a tray or tank and stops the unit, or starts a drain pump, before the water can overflow. We have no model list for it, so check the number on your old switch before ordering.

Air con stopping with a water or drain error?

When an air conditioner cools, it pulls moisture from the air and that water has to go somewhere. In units with a tray, tank or drain pump, the float switch rises with the water and trips at a set level. If it sticks in the up position, the unit can stop cooling and show a water full or drain error even though the tray is dry. If it sticks down or fails, the safety is lost and water can overflow onto the floor or ceiling. Clean slime from the tray and float before replacing the switch.

Fitting the float switch

Turn the unit off and isolate it at the switchboard before opening any covers. Air conditioners are hard-wired, so electrical work belongs with a licensed electrician or air con technician. Empty and clean the tray, note which way up the float sits, and fit the new switch the same way. Pour a little water in to check it trips before closing up.

Questions about this part

Does a stuck float always mean the switch has failed?

No. A float often sticks because of slime, dust or mould in the tray. Clean it first and see if the float moves freely. If it moves but the unit still shows the fault, the switch itself is likely faulty.
