      Anna HarperJul 31, 2025
      If your LG dehumidifier isn't working (neither the compressor nor the fan motor starts), here's what you can check: * **Power Supply:** Ensure the outlet has power. * **Plug Contact:** Make sure the plug is properly installed in the outlet, or replace it. * **Bucket:** If the Auto Shut Off light is on, empty the bucket. * **Humidity Control:** Turn the humidity control switch towards Max. * **Wiring:** Check for disconnected or loose wires, referring to the wiring diagram to connect or repair them.

      There are several reasons why your LG dehumidifier might be operating noisily: * **Fan Issues:** If the fan is cracked, out of balance, or partially missing, replace it. * **Foreign Material:** Check for and remove any foreign material causing a rattle. * **Tube Contact:** Adjust the tubing if it's hitting the frame. * **Fan Blade Contact:** Check the motor mount and tighten it if the fan blade is hitting the frame. * **Compressor Noise:** Internal compressor noise may require replacing the compressor. * **Loose Screws:** Tighten any loose set screws. * **Motor Assembly Bearings:** If the motor assembly bearings are worn, replace the motor if knocking sounds continue or if it's loose. Replace the entire motor assembly if it hums or the noise appears internal.

    Why is my LG DHA1260HL dehumidifier not dehumidifying enough?
    • T
      Tony SpencerAug 21, 2025
      If your LG dehumidifier isn't dehumidifying sufficiently, consider these points: * **Low Relative Humidity:** If the relative humidity is low, turn off the dehumidifier. * **Poor Air Circulation:** Ensure the dehumidifier has free and unobstructed air circulation by moving it to a better location. * **Clogged Assembly:** Clean the evaporator and/or condenser assembly if it's clogged with dust and dirt. * **Dirty Air Filter:** Clean the air filter. * **Motor Assembly Issues:** Check, repair, or replace the motor assembly if it's not operating correctly.

    Why does my LG DHA1260HL Other compressor cycle on the overload protector?
    • R
      Ricky MejiaNov 3, 2025
      Your LG dehumidifier's compressor might be cycling on the overload protector due to several reasons: * **Voltage Issues:** The line voltage may be too high or too low. It should be between 198V and 264V. If the voltage is intermittent, you may need a new power supply. * **Air Circulation:** Poor air circulation can cause this issue. Ensure the dehumidifier has free and unobstructed airflow. * **Dirty Assembly:** The H/E assembly might be clogged with dust or dirt. Clean the assembly. * **Motor Assembly:** If the motor assembly isn't running, determine the cause and replace if necessary. * **PTC Assembly:** Check and repair the P.T.C. assembly if it's bad. * **Electrical Issues:** Look for short circuits or grounds in the electrical circuit and repair them. * **Pressure Equal...

      If the motor assembly runs but the compressor doesn't on your LG dehumidifier, consider the following: * **Voltage:** The voltage must be between 198V and 264V. If it's outside these limits, consult an electrician. * **Wiring:** Check the wire connections. Repair or replace any loose terminals. If wires are disconnected, refer to the wiring diagram for identification and reconnect them. Also, ensure the wire connections match the wiring diagram. * **Rotary Switch:** Check the rotary switch for continuity, using the wiring diagram for terminal identification. Replace the switch if the circuit is open. * **Compressor:** Check the compressor for an open circuit or ground. If found, replace the compressor. * **Overload Protector (O.L.P.):** If the compressor has an externally mounte...
