Mini Split Air Conditioner Remote Not Working.

Problem:  The remote control will not operate the unit.  The battery has been checked and the unit was shut off to try and reset.  I suspect lightning.  Can the sensor in the unit react this way and can it be reset?

Solution:  Usually with remote control problems it stems from a broken controller.  The mini split remotes just don’t hold up to a lot of abuse.  I would think that a new remote would be the first step in problem solving.  If that does not work than I would have the sensor replaced.  The sensor is the device that receives the remote control signal.  Also, make sure that all the wires are connected to the control board (circuit board).  Evaporator circuit boards are usually located under the cover below the temperature display.  Sometimes they are behind a separate panel.  Check this first.

    I checked and my minisplit remote (model zhf/lw-15) has a bad connector on the battery connection on the remote. I put a meter on the batteries and together (series) they show 3Vdc. The voltage was ok (nominal design voltage). The display on the remote controller was blank. My minisplit is a Quietside brand. I will be replaceing the remote next, if I can find a compatable remote.

    Have you put a meter on your battery connectors in the back of the remote?

    Infrared remotes can be checked with a digital camera. Turn the camera on and point the remote at the lens. If it is working, you will see a whitish blue light on the camera screen.

    The temp will not set properly. The AC just gets colder and will noy cycle off. I have replaced the remote twice. The compressor has been replaced as well as the fan motor. Help!!

    Ed, lots of the mini splits have sensors in them. It sounds like one of your sensors have gone bad.

    i have an old York mini split. evap was not made by york & i have not been able to trace the mfgr, Neither can York. The remote is broken. I ran the unit through this last hot spell, but took a chance & shut it off with the on/off button on the evap. Well, now it is HOT again & I cannot turn the unit on by the switch on the evap. when i put it on, the damper modulates to the closed position, but nothing else. No power light, condenser stays off. IS THERE A WAY TO JUMPSTART THIS THING? I found a company in Atlanta that repairs almost any remote, but it will be at least a week before I know if they can even fix it. HELP!!

    Could you tell me where you found the replacement remote? Ours stopped working- batteries are fine, but the screen has nonsence flashing on it. IT is set to 75 and we’re at a loss. our minisplit model is QCIH-12A/QCOH-12A. Thanks for any info!

    To Goran, try to reset your remote control if there is such button on it.
