Will The AC Fan Run If The Compressor is Bad?

The air conditioner fan is responsible for circulating cool air throughout your home. If the compressor is not working, the fan will not be able to do its job properly and cool air will not be circulated. In some cases, the AC fan may still run even if the compressor is bad, but it will not be as effective in cooling your home. If you notice that your AC fan is not running as efficiently as it used to, it is important to schedule AC repair in Lebanon, OH with one of our HVAC professionals.  

Why isn't the AC Compressor Running, but the Fan is?

No Power

If there’s no power to the unit, the compressor can’t run. Check your circuit breaker or fuse box to make sure that the circuit for your air conditioner is not tripped or blown. If it is, flip the switch or replace the fuse and try turning on your air conditioner again.

Thermostat Malfunction

If your AC compressor isn’t operating, but the fan is, someone may have mistakenly adjusted the thermostat to the wrong temperature. If that’s the case, the fan will continue to run until the correct temperature is reached, but the compressor won’t engage.

Starter Relay And Capacitor Issues

The starting relays and capacitors are vital components in the compressor’s power supply. The capacitor supplies the necessary electricity to start and run the compressor, blower motor, and outer fan. If your AC compressor isn’t operating, but you hear humming from the unit, the compressor may be attempting to reach a non-functioning capacitor. With issues like this, you may need AC replacement in Cincinnati, OH.

Dirty Filters And Coils

Filters, evaporators, and condenser coils can become clogged with debris and dirt, causing the entire unit to shut down. The compressor is put under strain by dirty air filters and condenser coils, causing it to overheat. Clean the condenser coils, replace the air filters, and make sure there are no blockages or obstructions in the supply vents so that air may flow freely.

What Causes An Air Conditioner Compressor To Fail?

A variety of factors can cause a failing AC compressor.
  • No electricity
  • The circuit breaker has tripped
  • A blown fuse
  • Clogged suction lines
  • Clogged condenser coils
  • An incorrectly sized suction line
  • Low charge of refrigerant
  • Electrical issues
  • Excess refrigerant
  • Insufficient oil lubricant
  • Contaminants in the water supply

Signs Of A Failing Air Conditioner Compressor

  • Inefficient cooling: One of the first indicators of a failed compressor is inadequate room cooling. A bad compressor won’t be able to effectively regulate the refrigerant flow in the AC system, resulting in inefficient cooling. This might indicate you need an AC replacement in Lebanon, OH.
  • Loud noises: The AC compressor is powered by a sealed bearing. Your compressor may become noisy if these internal bearings fail or any other internal component fails.

AC Compressor Problems Can Be Resolved With Routine Maintenance:

Many compressors fail as a result of improper maintenance. Regular maintenance, however, will help you solve most of your AC compressor problems and it will keep your compressor from failing in the future.
