About This Item
The Pentair Air Blower Kit (460743) is the OEM replacement blower assembly for the MasterTemp 250NA natural gas heater.
⚠️ IMPORTANT: LICENSED TECHNICIAN REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
The air blower supplies the forced combustion air required for the MasterTemp 250NA's burner system to ignite and sustain a clean, efficient flame. A failed or degraded blower prevents the heater from reaching ignition, causes fault codes, or results in incomplete combustion. Replacing the blower kit restores correct airflow to the burner assembly and returns the heater to factory operating parameters.

Pro Tip
Before ordering, confirm your heater's model number on the rating label affixed to the unit — the 250NA designation must match exactly. The MasterTemp line includes multiple BTU ratings and fuel configurations; blower kits are not interchangeable across models. If your heater is displaying an ignition fault or airflow fault code, inspect the blower for seized bearings or debris obstruction before condemning the component — a blocked intake can produce the same fault as a failed motor. Have a licensed technician verify the fault code against the MasterTemp service manual before replacing this blower.
