Tempstar Furnace Motor Parts

Tempstar Furnace Blower and Inducer Motors

Tempstar furnaces depend on two critical motors to deliver heat: the draft inducer motor that starts each heating cycle, and the blower motor that pushes warm air through your home. When either motor fails, your furnace won't heat — or it runs but produces no airflow. Inducer motors often fail from pressure switch errors or blocked vent lines; blower motors typically wear out after years of daily use. Both are straightforward replacements with the right OEM part.

Run capacitors fail alongside these motors more often than you'd think. A weak capacitor means the motor struggles to start, runs hot, or won't run at all. Always test or replace the capacitor when you replace the motor — it's an inexpensive way to ensure the new motor doesn't burn out prematurely. Tempstar shares most motor platforms with Carrier and Payne, so your model number is key to confirm the correct horsepower, mounting flange, and voltage.

• Inducer motor assembly: Won't start, grinding noise, pressure switch keeps tripping
• Blower motor: No airflow, weak heat delivery, motor hums but won't turn
• Run capacitor (blower): Motor runs slowly, hums loudly, won't start, motor shuts off during cycle
• Blower wheel/impeller: Rattling noise, reduced airflow, wheel broken or bent
• Motor mounting bracket: Motor vibration, alignment issues during install

Tempstar Furnace Motor FAQs

What's the difference between the inducer motor and the blower motor?

The inducer motor runs first — it evacuates combustion gases up the flue and creates a vacuum that triggers the pressure switch. The blower motor comes on after ignition to push warm air into your ducts. If the inducer fails, the furnace won't start at all. If the blower fails, the furnace ignites but you get no heat delivery. Both are essential, and either one failing will stop your heating cycle.

How do I know if my Tempstar motor has failed or if it's the capacitor?

Try this: turn on the furnace and listen. If the motor hums but doesn't spin, the capacitor is almost always the culprit — a $15 to $25 fix. If the motor is completely silent or making grinding noises, the motor itself has likely failed. If you hear the motor running but feel no airflow at your vents, the blower wheel may be broken. Use your model number to confirm the correct capacitor µF rating — overfilling or underfilling the rating will damage the new motor.

Can I buy a generic/universal blower motor instead of OEM?

Not safely. Tempstar motors require exact horsepower, voltage, RPM, and mounting flange specifications. A universal motor with slightly different specs will overheat, draw too much current, or vibrate excessively. Use your Tempstar furnace model number to find the exact OEM motor — it's only $40 to $80 more than a generic option, and it help ensure fit and longevity.

My inducer motor is squealing but still running. Do I need to replace it now?

Yes. Squealing indicates bearing wear — the bearing will seize within days or weeks, and a seized bearing can damage the pressure switch or crack the inducer housing. Replace the motor assembly now. If you wait, you'll risk a complete furnace shutdown in the middle of winter and potential vent pipe damage from a backed-up inducer.

Tempstar Furnace Model Number: Where to Look

Tempstar typically prints the furnace model number on a data plate inside the blower compartment door. Turn off power to the furnace, remove the access panel, and check the label near the gas valve or along the cabinet frame. Look for the model number, not the serial number, and copy every letter, number, and hyphen exactly as shown. Type it into our model number lookup and the catalog narrows to parts made for your unit, including the motors and other associated furnace parts. Using the complete model number accounts for differences in voltage, horsepower, mounting, and cabinet design, so you can identify compatible parts without comparing specifications across multiple listings.
