Description
The Middleby 31432 is a genuine OEM blower (or fan) motor, rated at 1 HP, single-phase, designed for operation on 208/230 V at either 50 or 60 Hz. It’s used in conveyor ovens (especially Middleby Marshall models) to drive the airflow/blower component that moves air through the oven for even heating. Using the correct motor ensures the oven heats evenly, maintains temperature, and avoids overloading electrical components.

💡 Tech Tip:
-
Make sure you match voltage and phase exactly — single-phase vs three-phase mismatch or wrong voltage can damage the motor or cause poor performance.
-
Check electrical load (FLA/SFA) to ensure the power supply and wiring can handle start-up current.
-
Ensure the blower/fan housing matches the motor’s mounting dimensions and shaft size.
-
For airflow considerations, the motor must produce sufficient power for the blower it’s coupled to, otherwise air volume will drop and cooking consistency suffers.
📌 Note:
While this is a genuine OEM part, its compatibility depends on matching model number, serial number, and whether the oven’s blower housing/design accomodates the same dimensions. Always verify using your oven’s model/serial tag or manufacturer documentation before purchasing.
