Here we will discuss WHY THE BLOWER DOESN’T WORK AND WHAT TO DO. The blower in the furnace is the main component for moving air in the home. So it not will be a surprising thing for us that the furnace blower is not working, we will not get cooling or heating in the home. All types of things kept the blower working. Some are due to the blower motor. Other furnace components keep the blower motor from running. So let’s get started with WHY THE BLOWER DOESN’T WORK AND WHAT TO DO
What to do when the furnace blower won’t turn on
- The first thing to do for the furnace blower not working is to change the thermostat to fan-only mode. The fan-only mode also called fan mode does not heat or cool the home. it is only on the blower. If the blower is not turned on in fan-only mode check it what issue
- If you find that the thermostat is having a problem then test the furnace control on the control board. If there is connected R and G terminals on the furnace control board, that will override the unit to run in fan-only mode.
- The last parameters to check before following furnace error code. The furnace control board has a small indicator light on it. The indicator light will flash in a series based on the status of France.
- Such as if there is a problem with the furnace then the light will flash in a certain sequence to tell what is keeping the furnace from running.
- If the furnace does not find any problems then the light will normally blink on and off slowly. The certain light blink codes are different for each brand furnace brand, there is need to check the manual for bling codes for France.
Check the circuit breaker Of Furance
- Now if the furnace blower is not turning on check the circuit breaker.
- A breaker is a safety component that is used for the protection of instruments and wiring from high currents. if the breaker trips rest it and check it is working again.
- note that the furnace, not the breaker is tripping again. if the furnace breaker trips again can be a problem with the furnace.
Blower motor overload Checking
- The motor overload is a device used to protect the motor from any damage. Such as if the blower motor is stuck it will become heated and motor overload will trip.
- if the motor overload trips power is disconnected from the motor. it prevents the motor from damaging or getting fire. Mostly blower motors come with motor overload in the internal circuit to protect them from burning. The overload can be automatic or manual resetting.
- if there is a manual reset motor overload there is a small red button on the side of the motor. it is a blower motor reset button. The red button pops out when the motor gets overloaded. There is a need to press a button to reset the overload and the blower motor starts running.
- Automatic reset motor overloads do not have a button. But automatic rest motor overload will reset itself after the motor cooling down. Just wait then the motor overload will reset itself.
How to know if we have a PSC blower motor?
- The simple technique to tell that if there is a PSC blower motor check that it has a capacitor. Blower motor capacitors are oval-shaped and are strapped on the side of the blower motor. If the run capacitor is not working then the blower motor will not start. To check the run capacitor is working use a multimeter.
How to Resetting Furnace
- Resetting the furnace blower motor is an easy process that helps to solve problems with the unit. To start off the power to the furnace shut off the breaker connected to it. it is important to ensure safety during this process. After that remove the blower cover. The cover can be removed by removing screws about the front.
- Helps the blower cool down so that any metallic component an easy to access. When the blower is cool find the reset button that is red and exists on the backside of the motor. If the reset button has popped push it back. This button is connected to the small breaker in the blower that pops it if it is in overloaded conditions.
- After that blower motor must be reset. But if the red button on the back of the motor is not popped, it can be that the motor is affected and it is good to get the services of technicians for solving the problem.
How to Know When It’s Time To Replace Furnace Blower
There are many indications that we have to replace the furnace blower. The most common signs that help to replace furnace blowers are overheating and moisture damage.
- If the electrical and bearing parts of the motor are releasing heat they will stop the operation. it can occur if we do not minimize overheating through proper checking of vents, filters, and in-room airflow.
- Moisture damage can be caused due to humidity, leaks in the ceiling, or improperly connected coil. if water gets in the blower motor, can casues corrosion on the motor casing and control parts and also damage the wires and electrical parts. it resulted in a short circuit and casues the blower motor to malfunction of stop operation. Moisture damage can casues the growth of mold and mildew in France that can be bad for our health and affect the air in homes
How does the furnace blower work?
- The values of the furnace blower fan motor will operate at different speeds for enhanced efficiency. Low-speed values such as 750 CFM are used when the furnace is heating and high speed for circulating cool air drawn in through an external condensing unit when Furance is a component of the central AC system
- When the furnace combustion series is finished the control board will send 120 volts for the circulation blower fan motor. The blower fan will draw air through the return vent blow it past the heat exchanger and force new heated air through the venting home
- Note that the main factor in effective furnace working is air circulation. To make sure that air is circulated accurately at home, France must the at in a well-ventilated area. Do not connect the box or other storage components near the furnace.

Faqs
What causes no power to the blower motor?
Normally issue is a faulty blower switch but if there is an assurity the larger blue wire moving to the blower is without power then start to check the voltage. Ensure there are 12 volts on both sides of fusebox 30A and inside 10A fuses
Why do blower motors fail?
Some main reasons for the blower motor to fail are overheating and excessive moisture. When dirt, dust particles, and debris are created it causes windings and bearings to burn fast. Furnaces are normally connected in and out of a location, such as a garage, or utility room.
Why is my AC running but not blowing air?
if the air handler is running but not blowing air the main reasons are the broken AC blower belt and a problem with the motor. if the air handler is humming or buzzing but does not have mechanical sounds of the motor running, the a high chance of an issue with the motor.
