When an air conditioner remote stops working, the whole unit may look faulty, but the cause is often smaller and easier to narrow down. Batteries, dirty contacts, an infrared signal problem or the indoor unit receiver can all create similar symptoms. For a technical inspection, contact our air conditioner technician.
This guide explains safe checks you can do at home and when it is better to call an air conditioner technician from 166 Usta.
