Why did my AC All of a sudden stop working?

When your air conditioner suddenly stops working, it can be cause for alarm or it can be something as simple as a blown fuse or tripped circuit breaker. It is important to note that many common problems with air conditioners can be caused by inadequate maintenance.

What’s wrong with air conditioner?

The evaporator coil freezes when your air conditioner does not receive sufficient air needed for operation. A frozen evaporator coil can make your AC freeze up and stop working. Blocked vents and ducts, dirty filters, or a faulty fan can cause insufficient airflow in the system.

Is there a fuse for the air conditioner?

Air conditioners use fuses as a way to protect the condenser from being exposed to excessive amperage. Fuses are designed to handle a limited amount of amperage based on the maximum amount that the unit is rated for: If more amperage passes through, the fuse will blow to protect the condenser from overheating.

What causes air conditioner to kick on and off?

Your air conditioner may be short cycling because it is repeatedly starting up then overheating (and shutting down) due to a bad compressor, dirty filters, dirty coils, low refrigerant, or frozen coils. A malfunctioning compressor will overheat. Dirty filters will prevent adequate airflow and cause motors to overheat.

Why is my outside unit not coming on?

When an outside fan fails, the most likely cause is a capacitor issue. Capacitors may also go bad for several other reasons. A bad capacitor can’t properly power your AC’s fan, meaning the fan can’t spin. No air coming out of vents is a sign that you may have a bad capacitor.

How long should an air conditioning system last?

Though the lifespan of a home air conditioner varies based on many factors, those that are well-maintained should last 10 to 15 years. And by completing regular checkups and repairs – both big and small – many systems can last even longer.

How do you troubleshoot a window air conditioner?

The most common causes of your air conditioner not providing cool air are a dirty air filter and a damaged condenser coil. To fix it, try cleaning the air filter. If that doesn’t help, clean and inspect the condenser coil on the exterior of the unit. If damaged, it may need to be replaced.

Where are AC fuses located?

disconnect box
A fuse is a metal filament or wire, usually in some type of casing. It’s located in the disconnect box, connected to your AC. It is there to protect your machine, to avoid more serious problems.

Why does my outside AC unit keep shutting off?

If you haven’t had regular AC maintenance, the short cycling could be caused by dirty condenser coils. These coils are in the outside unit of your air conditioner and are responsible for dissipating the heat from your home to the outside air. And as your air conditioner struggles, it can overheat and shut off.

Why does my AC compressor shut off after 2 3 minutes?

If there is a leak in the refrigerant line, it can lower the pressure in your AC system, which triggers the compressor (the part of your AC that pumps refrigerant) to shut off. Once the thermostat calls for cooling again, the AC turns on, detects low-pressure levels again, then turns right back off.
