Faulty Wiring or Tripped Electrical Circuits

Air conditioners can fail for a variety of reasons. When the unit will
not turn on, you may have a problem with the wiring in the AC unit or
the wiring in your home.

You should first check the circuit breakers to determine if the air conditioner
tripped a circuit. If resetting the circuit does not solve the issue,
the next step is to rule out other causes.

Ice Buildup on the Condenser Coils

In some situations, ice may collect on the condenser coils and other components.
If this occurs, the AC unit may not turn on. Make sure that the air conditioner
is fully thawed before operating.

Dirty Filters and Condensers

AC filters should be cleaned or replaced to keep your air conditioner working
smoothly. If you ignore these basic maintenance steps, the AC unit may
stop working. Try replacing the filter before attempting to turn on the
air conditioner.

Mechanical and Wiring Issues

Besides the causes discussed, your air conditioner may stop working due
to mechanical or wiring issues. These problems typically require servicing
by an experienced professional:

  • Faulty motors and compressors

  • Dirty condensers and evaporators

  • Wiring or electrical issues inside the unit

  • Shortage of refrigerant

When your air conditioner does not turn on, rule out the simplest causes
first. Check your electrical box for tripped circuits, allow your AC unit
to thaw, and replace the air filter.

After attempting these simple fixes, you should hopefully have cooler
air. However, some AC issues may require professional repair. When these
solutions do not solve the problem, contact the experts at
