1. Poor Airflow:
When your air conditioner’s airflow is weak, it’s likely due to a broken blower motor. When the airflow from your furnace is low, the blower motor has a harder time forcing heated air via the ducts and into your home. A dirty or worn-out motor, a faulty capacitor, or both could be to blame for the sub-par airflow.
If you notice inadequate airflow, it’s better to have a professional inspect the system to see if the problem is the blower motor, the ducts, or the filter. If the blower motor is the source of the problem, it can be cleaned, the capacitor can be repaired, or the motor can be replaced.
2. There is not any circulation of air:
If there is no air movement, it could be because the blower motor is broken. If the motor is broken, you will need to get a new one. However, other causes of no airflow include a malfunctioning thermostat, fan control, or relay. Once again, calling in a professional HVAC technician for an inspection is your best bet for pinpointing the root of the issue.
3. Changing the Thermostat Settings Regularly:
The thermostat tells your furnace what temperature to keep at and how much heat to put out. There could be a serious wiring issue with the thermostat if the house never reaches the desired temperature. The issue could also be with your burner. It’s also possible that your furnace’s inefficiency is due to the fact that it needs a new motor blower.
4. The Unit’s Chilly Air:
If your furnace seems to be producing more cold air then hot, you should have it checked out. A number of factors, including filthy filters for the air, blocked air ducts, and a clogged blower motor, might cause your furnace to fail to provide heat..
5. The Heater Won’t Turn On:
As your furnace becomes older, the blower motor may become defective and refuse to turn on. It’s worrying if you have to constantly reboot it throughout the day. This calls for an inspection of your unit. To fix this, you can either fix the broken parts or get a whole new unit.
6. Your Blower Motor is more than 15+ Years:
It’s been more than 15 years since you replaced the blower motor in your furnace. The answer to this question is conditional on the home’s size and upkeep. If you’ve had it for too long, expect it to break down frequently or require expensive repairs. A premature shutdown of the furnace blower motors is the worst-case situation. In most cases, the price of a new blower motor for a furnace is close to $450.
7. A Pilot Light That’s Yellow:
A blue, steady flame coming from your furnace’s pilot light is normal. Combustion of natural gases from the blower motor is shown by the blue pilot light. It is also a sign that everything is running smoothly. On the other hand, if your pilot light is yellow, it may mean that toxic carbon monoxide is leaking into your home. Your technician should be contacted immediately if the yellow pivoted light is flickering. You should invest in a CO detector for your home’s long-term safety.
8. Weird Noises:
If your HVAC system is
, it may be due to an issue alongside the blower motor. If your blower motor is making squeaking or screeching noises, it likely has a broken belt or faulty bearings. Either the belt or the bearings need to be replaced and lubricated for this to work again. There may be a loose and broken part if a motor is creating a rattling, clanking, or slamming sound.
Sounding like something is being violently banged together or disconnected is a major red flag. At this point, you should disconnect the power and seek the assistance of a technician who can replace the motor. When these problems are addressed right away, they don’t have a chance to damage the motor or anything else that could be nearby.
9. Excessive heat:
There are a number of potential causes for the motor’s blower to overheat. Over time, the motor’s overheating could be the result of dirt and grime blocking its vents. An inefficient or broken blower motor will make it difficult to maintain a comfortable indoor temperature.
If the unit is overheating and not functioning properly, it will require more power to generate cold air, leading to higher energy costs. There are a few indicators that the fan motor is overheating. Smells of burning may waft through the vents, while the air conditioners may shut off to prevent further damage. If this happens, you need to get in touch with an HVAC technician to have the blower motor replaced.
10. Bizarre Odors:
When you switch on your furnace, if you smell something burning or like it’s overheated, it could be the blower motor. It could just be unclean, or perhaps certain parts are rubbing together and making noise and producing unpleasant scents.
11. Extremely High Utility Costs:
The most energy is consumed by the blower motor in your HVAC system. If your energy costs suddenly skyrocketed, it could be the cause. Your air conditioner’s motor will have to work harder if it’s old, has problems, or is dusty. Therefore, you will experience increased energy consumption.
Your air conditioner’s blower motor may benefit from being upgraded to a more modern, variable-speed type if it is somewhat old or if it just has one speed. When it comes to cooling your home, this kind of blower motor is able to adjust its energy consumption. As a result, less energy is lost in the process.
