Question about Carrier Heating & Cooling

Open Question

My 53QNL009/012 CARRIER SPLIT SYSTEM, comes on everytime i plug it in, the remote control works but isn't able to turn the unit off. A soon as the power is appplied to the unit I hear 3 beeps and the system starts. It was last turned on and off yesterday but the remote. When my wife returned home this afternoon the unit was running and she was unable to turn it off. The same remote works fine on the same (but larger) unit out in the family room? Thanks Ian

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.

Cannot turn unit on with remote


Hello,

the problem lies between the remote sensor of the unit or the remote control itself.

You need to test the remote with another unit or test another remote with the unit to actually confirm where the fault is coming from.

Regards.

LG Split unit turns itself off after a couple of seconds of opera


Check your remote control using your camera or cellphone camera as your eyes. Point the remote control transmitter to your camera and "on", light should emit in your remote control transmitter (means good remote). Reset the unit by disconnecting the power supply for 10 sec. then "on" again and start the unit. If it wont work you need a qualified tech. to solve the problem.Some of your safety device might be defective.

LG SPLIT SYSTEM AC.


Fixed fault by not only switching off AC unit at power point, had to pull out plug top & lead from wall for one minute. This must allow electronics to reset.
