FEXON RV Camper Furnace Blower Motor PF26157Q
This blower motor is marketed for Atwood and Hydro Flame furnace models including 8531-III, 8535-III, and multiple 8935/8940 series variants. The product lists cross-reference numbers such as 37357, 37698, 34009, and PF26157Q, making it useful for systems that require those OEM replacements.
Key specifications: 12 Volts DC operation and approximately 2250 RPM. These electrical and speed values are critical when matching to an RV furnace that expects a DC blower motor. The listing emphasizes application to a variety of Atwood Hydro Flame furnace series, which helps identify correct fit for many older and current installations.
Installation notes: ensure the motor mounting and shaft dimensions match your furnace housing and blower wheel. Confirm wiring connector type and polarity for DC systems before installation. Replacement motors labeled for Atwood series typically plug into the furnace blower harness or use similar terminal fittings.
Furnace Heater Blower Motor Compatible With Atwood 8525 IV 8531 IV
This Gobuywell motor is presented as a direct replacement for Atwood (Dometic) furnace models in the 85-IV series, including 8525 IV and 8531 IV. The cross-reference numbers include 37697, 20269K, and OEM model numbers often used in service parts lists.
The product highlights efficient circulation for distributing warm air throughout the RV heating system. While the listing emphasizes airflow performance, buyers should confirm motor voltage (typically 12V DC for furnace blowers) and match RPM or wheel size to the original motor to maintain expected airflow rates and static pressure characteristics.
Compatibility tip: use the listed replacement numbers and your furnace model number to verify fit. If the original motor uses a specific bracket or mounting flange unique to the furnace, be prepared to adapt the mount or use included hardware if provided.
Holdia Furnace Heater Blower Motor Compatible With Atwood 37697
The Holdia listing focuses on compatibility with Atwood / Hydro Flame part numbers 37697, 20269K, 30133, and models identified as 8525 IV and 8531 IV. As with other replacement blower motors, matching part numbers is the primary method to ensure a correct replacement.
Package details are minimal—”it’s just like the picture”—so confirm included hardware and connectors before purchasing. The product aims to be a one-to-one replacement for common Atwood furnace blower motors, which are typically 12V DC units with a specific shaft and fan wheel interface.
Installer considerations: verify motor shaft length and diameter against the original motor and check the polarity and wiring connector type on your furnace. If your furnace uses a ground or additional mounting bracket, make sure those points align to avoid installation delays.
HHQ RV Air Conditioner Motor With Capacitor (Replaces Fasco D1092)
While this motor targets rooftop air conditioner units rather than furnace blowers, many RV owners replace AC fan motors in multi-function assemblies. The HHQ motor cross-references Fasco D1092 and various Coleman Mach part numbers, listing 1/3 HP, 115V, and dual-speed operation 1675/1080 RPM.
Important features: included 7.5μF/370V capacitor, double shaft dimensions, and clockwise lead-end rotation. This makes it suitable for many Coleman Mach rooftop units where blower wheel and shaft geometry must match. The motor is specified for alternating current rooftop assemblies rather than DC furnace blowers, so verify system type before purchase.
Use case: select this motor when your RV’s rooftop AC or heat pump blower motor has failed and the unit lists any of the referenced Coleman or Fasco cross numbers. Confirm shaft length, double shaft sizing, and rotation to ensure compatibility with your blower wheel and housing.
SEAHEE D1092 RV Air Conditioner Fan Motor With Capacitor
The SEAHEE motor lists specifications aligning with common rooftop AC replacements: 1/3 HP, 115V, 3.4 amps, and two-speed operation at 1675/1080 RPM. The package includes a new 7.5 MFD capacitor, which is often required for proper motor starting and operation in rooftop assemblies.
Compatibility notes: the product cross-references Coleman Mach part numbers like 1468-306 and Fasco equivalents, and it fits several Coleman Mach AC model numbers and Airxcel references. Use the provided cross-reference list to confirm this motor will physically and electrically replace your rooftop AC motor.
Practical reminder: AC fan motors have specific shaft and mounting geometries; confirm blower wheel fitment and that included capacitor rating matches the original equipment to avoid operational issues.
Buying Guide: How To Choose The Right RV Heater Blower Motor
Selecting the proper replacement blower motor for an RV heater or AC assembly requires attention to several technical and fitment details. Below are key considerations to compare options objectively.
Match The Part Number And Model
- Use original part numbers (e.g., 37357, 37697, 37698) or furnace/AC model numbers when searching.
- Cross-reference listings on replacement parts to ensure compatibility; many aftermarket motors explicitly list the OEM numbers they replace.
Voltage And Motor Type
- RV furnace blowers commonly use 12V DC motors. Confirm voltage to avoid electrical mismatch.
- Rooftop AC blower motors typically use 115V AC and have different shaft and capacitor requirements.
RPM, Horsepower, And Airflow
- RPM affects airflow and static pressure; replacement motors should have similar RPM to the original to maintain heat distribution.
- For rooftop AC motors, dual-speed ratings (e.g., 1675/1080 RPM) indicate high/low operation matching original behavior.
Shaft Dimensions And Rotation
- Measure shaft diameter and length; blower wheels must slide onto the shaft securely without excessive play.
- Confirm rotation direction (CW or CCW) where specified; incorrect rotation can reduce airflow or damage blower wheels.
Mounting And Physical Fit
- Verify mounting flange, bracket holes, and overall motor footprint. Some replacements are drop-in, others require minor modifications.
- Check if the motor includes required hardware or if you need to reuse original mounting pieces.
Capacitor And Electrical Accessories
- AC motors often require a start/run capacitor; replacement packages that include a correctly rated capacitor (e.g., 7.5μF/370V) simplify installation.
- For DC furnace blowers, verify connector type and whether any harness adapters are needed.
Noise, Bearings, And Durability
- Sleeve vs. ball bearings: sleeve bearings are quieter initially but may wear faster under high temperatures; ball bearings often last longer in heavy-duty use.
- Consider motor reputation and warranty length if long-term reliability is a priority.
Installation And Safety
- Disconnect power and follow manufacturer instructions when replacing motors. For DC systems, ensure proper polarity and secure ground connections.
- When in doubt about wiring or mounting, consult a qualified RV technician to avoid damage to the furnace or AC unit.
Comparison Perspectives
- Part-Number Match: Prioritize exact OEM cross-reference matches for hassle-free replacements.
- Electrical Match: Never substitute 115V AC motors where a 12V DC motor is required, and vice versa.
- Physical Fit: A motor with the correct electrical specs but mismatched shaft length or mounting may still require adapter parts—factor that cost and effort into selection.
- Included Accessories: Motors including capacitors or mounting hardware can reduce installation time and the need for additional purchases.
When To Replace Versus Repair
- Replace the motor if the bearings are noisy, the motor does not start, or if it draws excessive current.
- If only the blower wheel is damaged but the motor spins freely, replacing the wheel may be a cost-effective option.
- For persistent electrical issues, inspect wiring, relays, and thermostats before replacing the motor.
Final Selection Checklist
- Confirm furnace or AC model number and OEM part number.
- Verify voltage and RPM specifications match the original equipment.
- Check shaft diameter, length, and rotation direction.
- Confirm mounting holes and flange alignment or plan for an adapter.
- Ensure required capacitors or accessories are included or sourced separately.
