Fasco draft inducers are used across many furnace and water-heater applications. Cross-reference charts can be helpful, but they work best when you have the OEM part number or equipment model number.
Safety note: A draft inducer is part of the venting and combustion safety system. Use cross-reference information for part identification, then have a qualified technician confirm installation and operation.
What a cross-reference can do
A cross-reference can point from an OEM or competitor number to a Fasco replacement. It can save time when the original part is obsolete, hard to read, or branded under the furnace manufacturer.
What a cross-reference cannot do
It cannot guarantee that a part is correct if the old assembly was previously replaced with the wrong item, the furnace was modified, the label is incomplete, or the manufacturer changed the design. Fasco cross-reference material notes that design changes can affect operating characteristics or dimensions, so final selection still matters.
Best information to collect
- Furnace or water heater model and serial number
- OEM inducer assembly number
- Fasco number on the motor or assembly
- Housing shape and outlet orientation
- Voltage, Hz, amps, RPM, and rotation
- Pressure port location
- Wiring plug style
- Gasket shape and mounting pattern
Assembly number beats motor number
Many buyers search the motor number and accidentally buy a motor that does not match the housing or wheel. Whenever possible, match the full inducer assembly.

FAQ
Is Fasco the OEM?
Sometimes Fasco made the motor or inducer assembly, but the furnace manufacturer may assign its own OEM part number.
Can I reuse the old blower wheel?
Sometimes, but seized or corroded wheels can be difficult to remove and may not be recommended. A complete assembly is often cleaner.
What if the exact Fasco number is unavailable?
Look for a direct replacement or supersession using the equipment model and OEM number.
