We had this terrible heatwave last summer. It was steaming hot outside so the AC was working like 24/7. After a couple of days in such mode, it started to act up a little. The fan sometimes was suddenly on and the lights were blinking while I tried to change the mode. Besides, the temperature on AC was changing itself at night. I thought that it was broken and I started to get thoughts that we wouldn`t survive the heat without AC. Luckily, I found a guide on eliminating my problem on
