Here are a few reasons why the A/C Compressor won't run;

  • Your air filters could be clogged.
  • You could be having dirty evaporator coils.
  • There could be a refrigerant leak.
  • The motor could be faulty.
  • The thermostat is either broken, needs batteries, blank or outdated.
  • The circuit breaker could be tripped.
  • The condenser lines could be dirty.
  • The fuse could be broken.
  • There is a wiring fault in the home.

How to Troubleshoot these Common AC Problems

To detect and fix these problems, you must have some background knowledge of the AC Compressor. If not sure, it's recommendable that you seek help from air conditioning repair experts near you. 

Fixes Recommendations for Faulty AC Compressor

  • Detach the filters from the unit, check if they're clogged and replace them if dirty.
  • Clean the evaporator coils. The evaporator coils are usually located near the hair handler or inside of the internal unit. Since it's located inside of the AC Compressor, it can be a complicated task cleaning them. 
  • Fix the refrigerant leaks. Refrigerant leaks can be due to corrosion on the coils when exposed to contaminants or if the system is outdated. To fix refrigerant leaks, you may need to replace your AC coil if it's outdated or in poor condition. American Air Cares expert technicians can also detect the leaks and repair your unit.
  • Check the motor. Now, if the unit was making strange sounds before failing to run, you may need to check if the motor is still in the best condition. To achieve this, you should have a technician do a capacitator test and have it fixed if there is only a slight damage. Replace the entire unit if the motor is damaged beyond repair.
  • Check the thermostat. This is the control panel of your unit. Test it to see if it's still functioning well. If it's faulty, try replacing the batteries or resetting it. Ensure that your power supply to the unit is off when doing the investigations.
  • Reset the circuit breaker. The circuit breaker could trip due to overload or when it's connected to an outdated appliance that's using too much power. If your circuit breaker is tripping continuously, get it checked out.
  • Dirt build-up on the condenser lines might also make it difficult for the unit to run. Try cleaning them to see if the problem goes away.
  • Check for a wiring problem in the home. It may not be easy to detect wiring problems in your home. Nevertheless, if you've had power issues in the past, that should give you a clue that your air conditioner problems may be due to wiring problems in the property. You'll need a certified electrician to help you check for possible wiring faults in the electricity.
