High pitched squeeling noise from mini split even when inside unit is off.


This is a normal problem is some air cons. Theres nothing much you can do . You unit would be under warranty you can get a tech out to have a look but he will probably just say theres nothing you can do about it.

All you can do is turn the unit of at the main power board when not in use.

Here is a forum where i have tried to help someone with same problem

Same loud crack noise also a high pitched beep every minute or so


The noise may come from a plastic piece that is around the outside fan ( that picks up the water ) and cools the condenser ( coil ). the fogs maybe condensation ( warm air and cool air mixing on the window ( heat from outside on the window and cool air inside ( poor seal around the widow ( Unit) .

Condensate blowing thru discharge vents when operating on high cool, unit is pitched 3/8in. there is no standing water in chassis tray, this unit just installed new out of the box


Try a lower fan speed, sometimes the velocity of the fan combined with high humidity lifts the moisture off the fins instead of allowing the water to properly drop to the pan.

Remote control


First you have confirm what really the defects is, is it the remote control or the control board.

HOW TO CHECK THE DEFECTIVE REMOTE CONTROL:
Check if the remote control if still good, using the camera of your cellphone point remote control to the cellphone camera and press the "on" button of your remote and you can see the light emitting from your remote control transmitter. If the lights emits that means your remote control is good, if not means the remote control is defective. If the remote emits light it means that the receiver at the control board in the indoor unit is defective.
