Replacing the fan motor in an air conditioning unit is a complex task that requires knowledge and experience. An incorrect size or type of motor won't work and could cause the unit to overheat or not move enough air, resulting in a malfunction. Before attempting to replace the motor, it is important to determine the cause of the fault or check if the safety switch turns off. It is also recommended to contact a heating, ventilation, and air conditioning (HVAC) repair service to schedule routine maintenance checks and inspect every part of the air conditioner, especially the condenser unit.
The condenser fan motor powers the fan blades, which cool the coolant in the condensing coils of air conditioning units from a hot gas to a cold liquid. A professional HVAC technician can replace a condenser fan motor in an hour or two, although most technicians also perform an inspection and possibly replace other parts at the same time, meaning that the full repair can take longer. It is important to never use the outdoor fan without turning off the air conditioner in the circuit breaker box, as this could suddenly spin and cause injury. The most notable thing is that the fan motor may not work at all, or it may make strange sounds in the outdoor air conditioning unit. Knowing the normal characteristics of each common type of HVAC motor is a fundamental first step in developing a long-term professional career in the HVAC industry.
A poorly replaced condenser fan motor can damage itself and the air conditioning unit and, as has already been said, can further overload the rest of the parts of the air conditioning system, which could result in the need for further repairs. Most air conditioners offer warranties that last between five and 25 years, so replacing this part may be covered by a warranty. An air conditioning or HVAC company will likely have the replacement part for the condenser fan handy and you don't have to ask the manufacturer or go to local home improvement stores. As you gain knowledge about air conditioning systems and their maintenance, you will improve your work as a technician. Take the time to familiarize yourself with the most common types of motors and learn how to repair or replace each of them as needed.
Instead, hiring a professional is often the best course of action for a complex repair like this. Replacing a fan motor in an air conditioning unit is not something that should be taken lightly. It requires knowledge and experience to ensure that it is done correctly. If you are not sure how to do it yourself, it is best to contact an HVAC repair service for assistance. They will be able to inspect every part of your air conditioner and replace any faulty parts with ease.
Additionally, they can provide advice on how to maintain your system so that it runs efficiently for years to come.
