Understanding the Issue
AC compressor and fan not running is pretty much what it says on the tin. It’s like turning on a tap and getting no water. Your AC isn’t cooling your home because the main players, the compressor and fan, aren’t stepping up to the plate.
Symptoms Indicating Your AC Compressor and Fan Aren’t Working
The biggest clue is, of course, the lack of cool air. But there can be other signs too like your AC making more noise than a rock concert or having an ice party on the coils. If you see any of these, you’ve probably got a problem on your hands.
Difference Between “Not Coming On” and “Not Running”
Think of it as the difference between not starting your car and not driving it. If your AC isn’t coming on at all, that’s a full stop. If it’s on but not running, well, that’s like your car idling in the driveway—lots of energy, but no movement.
Potential Reasons Why Your AC Compressor Isn’t Running
A compressor that’s playing truant can be like a detective story, with plenty of culprits—from a faulty power supply to an overheated system. Let’s shine a light on some of the usual suspects.
Power Supply Issues
Just as your phone won’t work without charging, your compressor needs power to do its job. So, if there’s a problem with your power supply, your compressor will be off-duty.
If your thermostat’s acting up, it’s like sending the wrong signals to your compressor. It’s like getting directions to your destination, but ending up at a dead end. A faulty thermostat might not be telling your compressor to kick in, even though your home’s hotter than a desert.
Compressor Overheating or Overload
Your AC compressor is a hard worker, but push it too hard, and it can overheat. Much like you’d feel exhausted after running a marathon in high heat, your compressor might just need a breather. An overload protection switch can help prevent this situation by shutting off the compressor when it gets too hot.
A broken capacitor is like a car with a dead battery—it won’t start. The capacitor gives your compressor the jolt it needs to start up. If it’s not working, neither will your compressor.
Potential Reasons Why Your AC Fan Isn’t Running
If your fan isn’t running, that’s another set of potential issues. It’s like a drummer missing from a band—the beat’s all off. Let’s uncover some common reasons why your AC fan might be on strike.
The fan motor is the ‘engine’ that drives the fan blades. If the motor’s busted, the fan blades won’t spin. Imagine trying to pedal a bike with a broken chain—that’s your fan with a motor problem.
Bad Fan Capacitor
Like the compressor, the fan needs a capacitor to start it up. A faulty capacitor is like a flat tire—it won’t get the fan going, no matter how hard you try.
The condenser houses the fan. So, if there’s an issue here—say, a blockage—it can stop your fan from running, much like a blocked door would stop you from entering a room.
Fan Blade Obstructions
If something’s blocking the fan blades, they won’t be able to spin. It’s like trying to swim in a pool filled with balls—something’s got to give.

Preventing Further Damage
Getting a professional to fix your AC can prevent more damage and cost. It’s like taking your car to a mechanic instead of trying to fix it yourself—sometimes, you just need an expert.
Ensuring Efficient Cooling and Energy Savings
