What the Blower Motor Does
Your furnace produces heat, but it relies on the blower motor to circulate that heated air through your home. The motor turns a blower wheel inside the housing to push air through the duct system.
A failed blower means no airflow, even when the system runs. The burners or heat elements might cycle on, but the air will stay trapped inside the cabinet without a working motor.
Specs for the 1009052 Motor
When you match an electric motor, the ratings on the data plate must match the original part. The Comfortmaker 1009052 motor carries the following factory ratings:
- Horsepower: 1/2 HP
- Voltage: 115V AC
- Amps: 10 Amps
- Speed: 1050 RPM
- Rotation: Counter-Clockwise (CCW)
- Frame: 48
- Phase: Single Phase
Confirming the Match Rules
Before choosing a replacement motor, check the rating plate on your current unit. Some units rely on ECM variable speed motors that are programmed for the unit, so you must always match the exact type.
When comparing your old motor to this part, follow these required match rules:
- HP: must be the same
- Speeds and volts: must be the same
- Frame and rotation: match your old motor
Signs of Motor Failure and Safe Replacement
If your system runs but blows no air, the motor could be burned out or stuck. However, a fan that hums but will not spin is often a bad capacitor, not a bad motor. Check your capacitor before assuming the motor itself has failed.
If you decide to remove the motor yourself, follow these basic safety steps:
- Turn off electrical power at the breaker panel and test for power before touching any wires.
- Discharge the capacitor using an insulated tool.
- Take a photo of every wire before removing the old motor so you know where each wire connects.
- Move wires one at a time to the same spots on the new part.
- Secure the motor in its mounting frame and ensure the blower wheel spins freely by hand.
Read your old part
- Turn off the breaker and open the furnace blower access panel.
- Find the metal data plate or printed label on the side of the existing motor housing.
- Check the part number on the label to verify it clearly reads 1009052.
- Verify the electrical specs show 1/2 HP, 115V AC, 10 Amps, and 1050 RPM.
- Check that the rotation is Counter-Clockwise (CCW) and the frame size is 48.
When to call a pro
Blower swaps take more steps than most DIY jobs. Hire a licensed HVAC technician for any step you are not sure you can do safely.
Questions
Why is my furnace blower humming without moving air?
A fan that hums but will not spin is often a bad capacitor, not a bad motor. Always inspect and test the capacitor before removing the motor.
Can I replace a motor with a different horsepower rating?
No, the HP must be the same. Using a motor with the wrong horsepower rating will cause improper airflow and can damage the equipment.
What tools are needed to discharge the motor capacitor safely?
Use an insulated tool to short across the capacitor terminals once the power is cut. Capacitors can hold a dangerous electrical charge even when the power switch is off.
What should I do if I smell gas while checking the blower motor?
If you smell gas, do not touch any switch. Leave the house and call your gas company from outside.
