Split system air coditioners (3 off) LG LST243C-2, remote controls work intermittently or not at all after batt change. Reset does not help. Are they able to be rejuvenated (?) or is replacement only option

Hi Russell Webe, just a guess, but sounds as though the remote receiver board is faulty, however you might try new batteries in the remote first,it may help. failing that it is time to call the serviceman. Also try turning the power off to the Ac unit for about 5 minutes and then back on again. This will reset the electronics and again may solve your problem regards. col www.digitalcontrols.com.au

Before buying new one, try with this step. Remove batteries from your remote and reset it after 5 minutes. And also remove DC wires plugged to indoor sensor display, and after 5 minutes re set it again. Now start your unit. Sometimes it will work out. Thanks.

bad remote control may something got spilled on it they do not like to get wet. Tom try google manufacture to get new is their power to the unit tripped breaker.Tom

The remote stopped working. So I changed the batteries Then remote signal's are OK But Indor Unit is not controlled by remote.

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.

Solution # 1, Check Condensor Fan Motor Capacitor 4uf or MFD
# 2, Check Motor Windings
# 3, Check Relay OR Defination Contactor
# 4, Check Connection Terminals

hope will help u 2 solve this

GOOD LUCK

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.

If you lift the flap on your indoor air con there is a Emergency operation button on your right you can operate the aircon from there. Push once for 20 cooling and twice for 22 heating

But sounds like you need a new remote. If you want to know how to test the remote please let me know

Hope that helps

- Check your air filter at the indoor if clean.
- Check your evaporator fins if clean.
- Check if no icing in your evaporator and outdoor pipes.
- If your air filter and evaporator fins is clean and icing is present then your unit is under charge.
- When your indoor drips check your drain pipe if there are water comes out. If no water drain from your drain pipes then your drainage is restricted.
- Flush your drainage with water using your garden hose to flush out dirts from your drainage.
