Question about Heating & Cooling

1 Answer

My LG ls-h246tnbo split system air conditioner intermittently turns itself on and off. Is there a part that I may replace to rectify?

It cools very well when working. Sometimes works fine. Othertimes it turns itself on and off (or just beeps) every couple of seconds. Is there a solution to this please

    Thanks for that. Have had PCB tested and cant find a fault. Could it be the external BCB soft start and not the internal PCB at fault? Thanks again for your help.

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!

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.

You have to try resetting the system. First turn the breaker off for the condenser and wait about 20 seconds. After you turn it back on the system should reset. Air Bulance AC Cleaning Repair Services

Froze up now won't cool


turn system off or leave the fan only on and thaw system out, when it is dry, check filter, if not the problem more than likely it was turned down to low or the freon charge is low and should be check by technician.

Wash out your outside coil and monitor the outside fan. sounds like a lockout due to dirty condenser or intermittent motor operation. Could mean condencer air problem.
