Criditpid HC21ZE117-B Inducer Motor Kit With Blower Wheel

Check Price on Amazon

The Criditpid kit contains a 115V inducer motor rated at 1.5A and 3200 RPM, plus a 4″ diameter blower wheel and mounting bracket. Technical specs list clockwise rotation and a 28-blade wheel, aligning with many Carrier/Bryant style draft inducer assemblies.

This product targets furnaces using part number J238-150-1571 and similar models. It is presented as an ideal replacement for certain Carrier/Bryant 58PAV series or equivalent systems that require a compact, higher-speed inducer blower.

Installation notes: the kit nature reduces the need to transfer parts from the old unit. Verify blower wheel diameter, rotation, and bracket hole pattern for proper fit. The manufacturer supplies a detailed cross-reference list to match many legacy numbers.

Fasco Upgraded Furnace Draft Inducer Exhaust Motor 024-34558-000

Check Price on Amazon

Fasco lists this product as a brand-new upgraded inducer motor for exhausting combustion gases in compatible furnaces. Fasco is a recognized OEM and aftermarket motor brand, often used as a direct replacement where the original Fasco part number or equivalent is specified.

Because the description focuses on the component function—expelling exhaust—this motor is intended for systems where the original inducer has failed or where an upgraded performance or durability option is desired. Cross-reference to your furnace’s OEM part number or service manual is recommended to confirm fitment.

Technical fitment: check electrical specs, rotation, and mounting dimensions against the original motor to ensure the upgraded unit interfaces correctly with the inducer housing and pressure switch plumbing.

Hipoilk 903404 Draft Inducer Blower Motor For Nordyne

Check Price on Amazon

The Hipoilk 903404 is specified as a direct replacement for many Nordyne, Nortek, and related furnace models. Electrical specs list 120V, 3100 RPM, 0.65A, and about 38W, matching OEM-style inducer motor characteristics for compact high-speed housings.

Dimensions and wiring details are provided in the feature set: unit size and a 2-prong Molex plug with approximately 9-3/4″ wire length. This level of detail helps match wiring harnesses and physical clearance when swapping units in OEM housings.

Replacement compatibility includes part numbers such as 903404 and 65404, and lists many cross-reference numbers useful for technicians. Verify rotation, plug type, and overall length for a seamless replacement.

Hiorucet 0131M00002P Inducer Motor For Goodman Amana

Check Price on Amazon

This Hiorucet unit lists compatibility with Goodman and Amana part numbers including 0131M00002P. Specifications show 115V and a higher amperage around 1.96A, which can indicate stronger starting torque for more restrictive heat exchangers.

The listing emphasizes that the inducer is the first component to start during a heat call and is responsible for pulling flue gases through the heat exchanger. The kit includes a gasket for sealing the mating surface, a useful inclusion during replacement to prevent exhaust leaks.

Confirm that the rotation, electrical connector, and gasket shape match your existing assembly. This product also lists Fasco cross-references for those replacing older OEM motors.

Buying Guide: How To Choose The Right Gas Heater Inducer Motor

Selecting an inducer motor requires attention to electrical, mechanical, and compatibility details. The guide below covers the key considerations to validate before purchasing a replacement motor.

1. Confirm OEM Part Number And Cross-References

Locate the original motor part number on the motor label or in the furnace service manual. Use cross-reference lists when available. Many aftermarket listings include multiple OEM numbers—match at least one listed part number to ensure fit.

2. Voltage, Amperage, And Power Requirements

Match the motor voltage (usually 115V or 120V in residential furnaces) and rated amperage. Amperage differences can affect the motor starter and fusing—ensure the replacement falls within the furnace’s electrical design limits.

3. Rotation Direction And RPM

Verify the rotation (clockwise or counterclockwise) and RPM. Incorrect rotation can reduce airflow or prevent proper operation. Many inducer motors specify rotation in the features; match this to the original.

4. Physical Dimensions And Mounting Pattern

Compare flange hole patterns, shaft length, and overall size. Some motors require specific bracket or housing alignment. If a replacement provides a mounting bracket or blower wheel, confirm compatibility with your housing.

5. Blower Wheel Specifications

When the wheel is included or transferred, check diameter, width, blade count, and rotation direction. Mismatched wheels alter static pressure and airflow, potentially causing pressure switch or combustion problems.

6. Wiring Connector Type And Lead Length

Confirm the connector type (e.g., Molex, male/female spade) and lead length. Some motors include pre-attached plugs compatible with OEM harnesses; others require splicing or an adapter.

7. Gaskets And Sealing

Sealing between the inducer housing and heat exchanger is critical for safe operation. Choose units that include a gasket or plan to reuse/replace the gasket to prevent exhaust leaks.

8. Certification And Safety Approvals

Look for safety markings like ETL or other approvals. These indicate the component meets electrical and mechanical safety standards for residential use.

9. Warranty And Support

Check the warranty period and seller support. Warranties provide recourse for premature failures and indicate the supplier’s confidence in the replacement part.

10. Compatibility With Pressure Switch And Controls

The inducer must create sufficient draft to satisfy the furnace pressure switch. If upgrading or changing airflow characteristics, confirm the pressure switch operates correctly with the new motor’s performance.

11. Installer Considerations

Professional installation is recommended for gas furnace components. Technicians will verify safe operation, ignition sequence, and proper venting after replacement. If you are experienced, ensure power is isolated and follow manufacturer guidance.

Comparison Perspectives

• Aftermarket Vs OEM: Aftermarket units may offer cost savings and broader cross-references, while OEM parts match original specifications and mounting exactly.
• Kit Vs Motor-Only: Kits that include blower wheels and brackets simplify installation but require verifying wheel specs. Motor-only options can be cheaper but may require transferring hardware.
• High-Torque Vs Standard: Higher amperage motors can overcome restrictive heat exchangers but ensure electrical compatibility. Standard motors match typical OEM specs.
• Brand Reputation: Established OEM brands like Fasco are commonly used as direct replacements. Newer aftermarket brands can be reliable but check reviews and warranty terms.

Following these checks and matching key specifications minimizes downtime and ensures the replacement inducer motor performs reliably within the furnace combustion and safety controls.
