What to do if my LG SP121CA NL0 does not work?
- S
  Samantha StokesAug 4, 2025
  If your LG Air Conditioner doesn't work, first ensure the power cord is properly plugged into the outlet. If it still fails to operate, check for a blown fuse or tripped circuit breaker and replace the fuse (Fuse Type: Time Delay, 250 V~, 3.15 A) or reset the breaker. Also, if there was a recent power failure, wait three minutes after power is restored before turning the unit back on. If the voltage is too high or low, check the circuit breaker. Finally, if the unit turned off at a preset time, simply press the power button again.
