FASCO A157 Induced Draft Furnace Blower 115V 1.3A 60Hz

SKU CH-426T-M33JH

An induced-draft furnace blower for natural-gas furnaces, 115 V AC, 1.3 A, 60 Hz, 3,400 RPM max fan speed, shaded-pole motor, Mag-Mate terminal, replaces Goodman models 70022307, 70023219, B1859005.

  • 115 V AC operation suits standard residential furnace wiring
  • 3 A draw keeps circuit loading low for safe replacement
  • 3,400 RPM motor speed delivers strong induced-draft airflow
  • Shaded-pole motor design provides reliable single-phase starting
  • Direct replacement for Goodman models 70022307 and 70023219

Direct-fit Goodman replacement

The FASCO A157 induced-draft blower is built to replace Goodman furnace models 70022307, 70023219, B1859005 and FB-RFB185. It runs on standard 115 V AC single-phase power at 60 Hz and draws 1.3 A. The shaded-pole motor is rated for Class B insulation and reaches a maximum fan speed of 400 RPM with the motor spinning up to 3,000 RPM.

Mag-Mate terminals simplify wiring

The blower uses Mag-Mate electrical connections that accept stripped wire ends without separate crimp terminals or screws. This reduces the number of loose parts on a service call and speeds up the swap when the original inducer fails. No additional control board or harness is bundled, so the installer reuses the existing furnace wiring and pressure-switch tubing.

Aluminium-steel housing fits 4 7/8 in inlet

The housing combines aluminium and steel for corrosion resistance in the flue-gas path. Its 4 7/8 in inlet diameter matches the specified Goodman openings, allowing a bolt-on installation without adapter plates. The unit is not suited for oil-fired appliances or furnaces that require a different inlet size or a factory outlet connection.

Questions about this item

How often should the shaded-pole motor bearings be checked or replaced?

The motor uses a shaded-pole design with Class B insulation running at up to 3,000 RPM; bearing wear depends on cycle frequency, so inspect during annual furnace service.

What limits continuous run time before the motor overheats?

Class B insulation and 1.3 A draw at 115 V set the thermal ceiling; sustained operation near the 3,000 RPM max speed will hit temperature limits first.

How loud is the blower and how hot does the housing get during all-day heating cycles?

The shaded-pole motor produces a steady hum at 3,000 RPM and the aluminium-steel housing becomes warm to the touch after extended use.
