Air Conditioner De icing Prob.

Any Air Con gurus around. Problem is a LG LWC092-RH2 domestic window type reverse cycle Air Conditioner which when in heating mode frequently decides it needs to de ice itself even though there is no ice to remove. Makes the unit a bit useless for heating as its de icing more than heating. What conditions are usually measured to determine when an air con needs to de ice. The unit doesnt have any obvious thermistors or air flow detectors on the external evaporator so I cant figure out whats activating the De icing.

Thanks

Yep thats a problem Lucky it Goes

It doesn't necessarily have to have obvious ice to go into de-ice. If it is extremely cold outside eg 0 degC or less it will drop into de-ice mode when there is a big enough temp differential that the gas is returning to the fan coil at too low a temp. This is so it doesn't blow cold air at you. Someone else may be able to go into more detail for you. Cheers,

Thanks for the above. The Unit actually works really well when its used for cooling and they are dirt cheap. The de icing is happening at outside temperatures well above 0 deg C, sometimes up to 10 deg C. The unit has a microprocessor type of control system thats initiating the de icing, but I cant figure out what inputs its using to decide to do this. Ill see if there are any pots or things I can adjust and see what happens.
