Nothing annoys on a hot afternoon than the air conditioner turning on and off after every 5 \u2013 10 minutes, right? So, does your air conditioner turns on by itself, and you wonder why?<\/p>\n\n\n\n
The air conditioner may turn itself on due to an oversized unit, Energy Saver or Sleep Mode, dirty air filter or coils, or wrongly placed or bad thermostat. Other issues include a dirty compressor, tripping safety switch, frozen coils, clogged drain, low refrigerant, or faulty wiring or component. <\/strong><\/p>\n\n\n\n The AC components in this case that could fail and cause the unit to turn on and off include the compressor, condenser, relay blower motor, cooling fan, or electric control board (ECB).<\/p>\n\n\n\n Some of these components fail from short circuiting while others from breaking and wearing. I’ll discuss them to let you know what to check when your air conditioner turns on and off at will. <\/p>\n\n\n\n Let’s jump into it!<\/p>\n\n\n In a rush? Below is a quick troubleshooting guide when your AC repetitively turns on and off. <\/strong><\/p>\n\n\n\nAir Conditioner Turns On and Off by Itself (Quick Troubleshooting Guide)<\/h2>\n\n\n\n
