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?
