Dépannage clim: suspicion du détendeur partiellement fermé
I'm responding to a problem with ice buildup on an air conditioning cassette, causing water droplets to drip onto the floor and flood it. Initially, I suspected a low refrigerant charge, but that wasn't the issue. I then focused on a faulty expansion valve. As a precaution, I also replaced the indoor unit's battery sensor to better detect excessively low temperatures and shut down the outdoor unit to prevent frost formation. I also flushed the system with nitrogen in case of a blockage. Please follow the step-by-step instructions. Enjoy the video.
