Question about Carrier Heating & Cooling

Open Question

I have an LG Split System Air Conditioner Model LSM304H-1 and the remote seems dead. If the reset button is pushed the panel lights up with all symbols but the on/off button does nothing. The screen on the remote is blank. New batteries have been installed.

Check your remote control the timer may be activated. Or try to push the reset button on your remote control to set it to default setting or just pull out the battery then insert it again then try. If problem persist then qualified technician is needed.

SOURCE: My Ruud Air Conditioner Model UAMB-048JAZ is not blowing cool air

3 things it could be:

#1 problem with AC units - dirty coils, this leads to many other problems and is caused by neglecting to change filters monthly. You can buy coil cleaner commercially, but it is not the coils you see that get dirty. There is another set inside that is usually not visible. If you look outside and your unit is "iced up" there is a 98% chance that is your problem. Sometimes it could be iced and you can't see it from the outside. Solution, turn AC off and blow fan to thaw. When thawed, clean coils with coil cleaner and coil comb.

Relay switches, you already pushed it so you may have a bad switch.

These are the two most common problems. A mechanic will be quickl to say it is your compressor for $. There are normally only half a dozen things that go wrong if your AC is 10yrs or less. If it is over that, it could possibly have a more serious problem. (Secret hint - I have known AC's to last 30+ years if the filters are changed regularly. Letting dust and dirt build up on coils invites a host of other problems due to the stress it puts on the other components.

Sound like a defective receiver board. Have this checked. Also check to see that your remote transmits. Hold the top part of the remote to your phone or digital camera lens. press a button and a light should appear on the screen of your phone or digital camera screen.

Remote is working- but unit won't turn on


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). Check for reset or rst button in your remote control and push it to reset and test it in your unit. If wont work means either the receiver board or mean board is defective.You need a qualified tech. for this problem. For the mean time you can use manual button to operate the unit.

Kelvinator Split System Air Conditioner not turning on.


On some remotes there is a reset button which is pressed by using the nib of a pen. Or if this does not work you should look under the cover for a manual button, most units have one, and see if the aircon responds. I suspect your remote sensor is faulty, but try the previous suggestions first.

LG Split system (ceiling cassette)


Check your remote control by using your camera or cellphone camera as your eyes. Point the remote control to the camera and "on" the remote control. If no lights emits in the remote control means that your remote control is defective If lights emits then the remote control is ok. Try also to locate the reset or rst button on the remote control if available and reset it, then try. If it wont work may be the receiver board in the unit is defective.

Lg split system air conditioner


Try sutting off the power to both units. This may reset the unit. Check out the service manual at LG website www.lgusa.com. Go to their support page and put the model number in. Remove and replace the batteries in the remote. If there is a communication error, the inside unit will display 3 flashes. If all else fails, call LG at 1-800-243-0000. Good Luck!
