Hey sork
not familiar with that model, but generally if there is no removable plate at the pipe connections or drain pump access from the outside, you are gonna have to do it the hard way.:confused:
cheers

easiest way if there is no access plate is to reomve the fan blade on the cassette,then if you are lucky you can reach to the coil sensor,remove the lift pump if req ,it beats supporting the ceiling,removing the facia and electrics to then dropping the drip tray

thank you everybody for the help, i can reach the pcb board and remove the sensor but the problem is the coil end.

thanks charlie, it is a D series . model: ATNH30GPLED OR UT30NPD
my problem is the sensor side in the coil . until i get to it i cannot find out were the fault is the pcb or the sensor.

good advice, considering its an LG.
im pretty sure all their fault codes should read: 'possibly faulty sensor'

whoever makes their themistors should be shot. they reckon they improved their design and blah blah, but the thermistors are still the biggest problem with lg's

there area manager for lg tells me they use the same sensors as mitsi and daikin but its a bit funny that in the last two years the number of mitsi sensors i have fitted is 0 the daikin sensors 2 and lg?a set a week
