I want to know that how mini split system automatic work? there is any thermostate or any other device?


Generally, they are operated by a remote control (similar to a television), although some units do have a wired wall control option as well. The indoor and outdoor unit has sensors that measure temperature (to control the operation of the mini-split) and (once the remote is set) the sensors control the system until it reaches the set point set on the remote.

I have a split-type aircon (brand: LG) with remote control.It has power and display when i put on batteries. but the aircon unit does not respond to the remote control. what do i do to fix this?...


Lift the front cover of the air con, on the right hand side there is a button or a hole which has a button inside which you can press which is for manual starting of the air con. If this works, then you will know the remote is faulty, if it still doesn't work, check that the isolator switch for the air con hasn't been turned off. There will be 9Or should be) a switch outside next to the air con outdoor unit to switch power on / off to the air con. If not, there should be switch inside the meter box at the front of the house. Make sure they are switched on.

Mt timer butoon is stuck on timer so unit wont work


All LG room air conditioners should be able to be operated without using the remote, by just using the controls on the unit. Replacement remotes are available from an LG service provider.

medev,

there is a lot of reason why your LG split unit would not work by remote control.
first likely trouble is the remote itself. it could have drop from a height and broke the remote, or corrosion has set inside the remote if you left an old battery for a long time and it could have broken it.

secondly which is not more likely to happen is the remote receiver in your unit got broke that is why it can not communicate with your remote controller. it could happen if someone has serviced your evaporator and could have disconnected wires to the receiver , or wires were just left not connected.

you can test the remote if you have an identical unit which is working with a working remote. use the working remote to your unit then you can decide.
i hope i was able to help.
