Parts for Jenn-Air C238B-C: 01 - Blower Plenum Parts

This blower wheel mounts on the drive motor and pushes air through the dryer drum and out the exhaust. Replacing a worn wheel restores proper airflow for consistent drying and helps prevent overheating and nuisance shutdowns. What it does:

• Moves air across the heater, through the drum, and out the vent to remove moisture
• Helps maintain proper airflow and temperature inside the dryer
• Common failure symptoms: reduced or no airflow at the exterior vent, longer dry times, unusual scraping/thumping or vibration from the blower area, or overheating/shutoff
• Cracked fins or a stripped hub can cause the wheel to slip on the motor shaft

• 1 blower wheel

• Disconnect power and turn off gas supply before servicing
• Access the blower housing per your model's service instructions; remove the retaining hardware and replace the wheel in the same orientation
• Clean lint from the blower housing and vent path; inspect the motor shaft and blower seal for wear
• Reassemble and verify the wheel spins freely without rubbing; check airflow at the exterior vent

Replace your cooktop's downdraft blower motor when ventilation fails or makes unusual noise. Restores proper exhaust function. Verify fit with your model.

Factory-style mounting screw secures panels, brackets, and trim to your appliance frame. Replaces worn, stripped, or missing screws for proper fit.

This motor isolator is a vibration-damping grommet that cushions the motor mount to reduce noise and prevent metal-to-metal contact. Replacing worn isolators helps keep the motor seated correctly and the appliance running quieter and smoother.

• Cushions the motor to minimize vibration transfer to the chassis
• Helps reduce rattling or buzzing noises during fan/blower operation
• Supports proper motor alignment and mounting stability
• A common maintenance item when rubber mounts become cracked, hardened, or missing

• Disconnect power and allow hot components to cool before service
• Access the motor mounting points; replace isolators in matched locations
• Inspect adjacent mounts and hardware; replace additional isolators as needed
• Do not overtighten fasteners—compress the grommet evenly without deforming it

Sheet metal pan head screw secures panels, brackets, and components to appliance cabinets. Replace missing, stripped, or corroded screws to restore fit.

This locknut is a small threaded retaining nut used to secure rotating and stationary appliance components, helping keep assemblies tight and stable during operation. It prevents parts from loosening and reduces vibration-related issues. What it does:

• Secures shafts, pulleys, or fittings to prevent axial movement
• Keeps assemblies fastened under normal vibration and load
• Helps stop wobble, grinding, or part separation caused by a loose connection
• Works with the matching threaded stud, shaft, or fitting for a proper hold

• Disconnect power and follow appliance safety procedures before servicing
• Use the matching thread size and engage threads fully; hand-start before tightening
• Tighten securely without overtightening; use the correct driver or socket for the nut
• Inspect mating threads and replace if damaged

Traps grease and particles from cooking to maintain efficient ventilation. Replace every 6-12 months depending on usage. Confirm fit with your model number.
