Defective AC Fan Motor
Motors are in the top failures for heating and cooling systems. They fail either due to age or improper maintenance. A properly maintained motor will provide years of trouble free operation, and mean that you will likely not need an AC repair company like Ambrose Air to be giving you worse news.
How do you know if your motor has failed or is about to fail?
During routine maintenance checks HVAC technicians will monitor the amperage load to the motor. A high amperage will indicate the motor is working too hard and is going to fail in the near future. The easiest way to check the amperage is with an amp meter on the common wire to the motor. Most motors use multiple speeds and each speed has its own specific wire. Using the common wire for an amperage reading takes out the guess work
When you turn on your system no air comes out of the vents and you have already checked for a dirty filter and clogged evaporator coil.
The motor makes a humming sound and does not start.
The motor starts and runs for a short period of time and shuts off again. This is due to the motor overheating and shutting off on thermal overload. HVAC motors have thermal overloads to shut the motor off when it becomes too hot. The easiest way to check this is to manually check the motor using your hand. BE EXTREMELY CAREFUL WHEN DOING THIS! A hot motor can and will burn you. If you are checking an indoor blower motor, be sure to disconnect the power prior to checking. Place your hand close to the motor without touching it and sense the heat. If it is too hot to touch, then the blower motor is overheating and it is time to replace it. An outdoor motor can be check by feeling the grill it is attached to without taking the cover off. If the motor is attached in another fashion then follow proper safety to check.
The air coling out of the vents has a hot electrical burning smell to it. An overheated motor is one of many parts that will omit a smell when is failing. Turn the power off! The hot electrical smell can be noticed on condenser motors just by standing over the unit when is running.
The motor starting is making a louder than usual noise and it is slow to come up to speed.
A motor can be started manually be spinning the fan or blower wheel. USE CAUTION WHEN DOING THIS AS INJURY CAN RESULT. Use an object such as a wood stick to start the fan or blower wheel. If it is hard to spin, then the motor has failed.
Defective AC Fan Motor FAQ
Why is the motor shaft loose?
If you are able to move your motor shaft with little effort, then the part is loose. This part shouldn’t be able to be moved at all. Replacing the fan motor can restore functionality and get the fan circulating properly again. The dual shaft fan motor becomes defective over time along with the bearings become loose.
What to expect when attempting to replace a defective AC fan motor?
The AC fan motor can be replaced for around $400. This is assuming that the fan motor has stopped running because of the start capacitor. When in doubt, contact our Orlando AC repair specialists for assistance.
How come I can hear the compressor running and the fan motor is not turning?
A bad capacitor could be the problem. You can purchase testing equipment of have it tested for free at a local hardware store. Capacitor testing will reveal the state of your AC fan motor.
Why is my AC producing so little air?
The blades on the fan get accumulate dust and debris, which will eventually slow down the system. The blower motor may have difficulty producing adequate amounts of air if the fan speed setting is wrong. Changing the fan speed may be all that’s needed to increase air flow through the system.
What do I do if the fan won’t turn?
The very troubleshooting step is to try to manually turn the blade on your own. Once you’ve verified that it can move, you need to see whether or not the system is getting enough power. If the power reaches the fan motor, but you aren’t able to get it running, you need to get a replacement AC fan motor.
How long is my system supposed to last?
You’re system can last up to 15 years if it is well-maintained. The average life of an air conditioning unit is ten years. The system should be serviced annually. With routing serving, aging parts can be quickly replaced before other system parts are affected.

What is the SEER Rating?
The SEER (seasonal energy efficiency ratio) is how the efficiency of your heating and cooling equipment is measured. The SEER is the amount of cooling your system will deliver per dollar spent on electricity, as compared to other systems. For example, a 3-ton unit may have a SEER efficiency rating of 13, 14, or 15. The higher the SEER the more efficient the system will be. The SEER rating of any given unit can range anywhere from 13 to 21.
Which brand of AC is the best?
Why is the SEER rating on the Energy Guide different than what my dealer quoted?
Why should I have regular (or preventative) maintenance? And how often should I have it performed?
Your heating and cooling systems work incredibly hard to perform their functions for your home everyday. The constant stopping, starting and continual operation can wear down any machine if the proper care and maintenance is delayed. However, by performing regular maintenance, you can maximize the lifecycle of your heating or cooling unit and guard against many common equipment failures. Preventive maintenance inspections performed on a regular basis can uncover leaks, rust, rot, soot, frayed wires and corroded electrical contacts that the naked eye may not notice. You should have maintenance done on your system regularly to ensure maximum efficiency and allow prevent possible problems that may occur in the near future.
What equipment requires regular (or preventative) maintenance?
At least twice a year heat pumps and air conditioners require a professional tune-up. Because gas-fired equipment functions with greater efficiency, they only need to be serviced every other year. Inspections on boiler and furnace systems should include ductwork, pipes, dampers, valves, the chimney, registers, radiators, pumps, blowers, fuel lines, the gas meter, oil tank and every part of the actual furnace and boiler. Meanwhile, heat pump and air conditioning unit inspections should also include inspections of the fan, compressor, indoor coils, outdoor coils, line kits and refrigerant lines.

What are the advantages of a programmable thermostat?
Since they are electronic, programmable thermostats are more accurate and efficient than thermostats that contain mercury. With programmable thermostats you can control the temperature in your home at different times of day without ever touching your thermostat. Because everything is automatic, you will never forget to change the setting on your own.
What type of filter should I use? And how often should I replace it?
Standard filters work to keep your system and its ductwork clean, but they don’t really improve indoor air quality. To do that you need a media filter. The media filter rests between the main return duct and the blower cabinet and will improve dust and particle removal by seven times that of a standard filter. However, upgrading to a pleated media filter will remove everything from insecticide dust to airborne viruses from the filtered air. Always choose a filter that matches your blower’s capacity. For optimum efficiency and filtration,Ambrose Air, Inc. recommends that you replace your disposable filters at least once a month. If you have washable filters, they should be cleaned once a month.
