3. Compatibility
This replacement timer knob is compatible with the Faberware HF-919B air fryer. It is crucial to verify that your air fryer's timer shaft is a 6mm D-shaped type. Air fryers may feature different shaft types, such as pin-type or D-type. This specific knob is designed exclusively for D-type shafts.

4. Installation Instructions
Follow these steps to replace your air fryer's timer knob:
- Power Off: Ensure your air fryer is unplugged from the power outlet before beginning any installation.
- Remove Old Knob: Gently pull the existing timer knob straight off the shaft. If it is broken, carefully remove any remaining pieces.
- Verify Shaft Type: Confirm that the exposed shaft on your air fryer is a 6mm D-shaped shaft. Refer to Image 3.1 for visual confirmation of the D-shape.
- Install New Knob: Align the D-shaped opening of the new Tolxh HF-919B knob with the D-shaped shaft on the air fryer.
- Secure Knob: Push the new knob firmly onto the shaft until it is fully seated. It should fit snugly without excessive force.
- Test Functionality: Plug in the air fryer and test the knob's ability to turn and engage the timer mechanism.
If the knob does not fit or feels loose, re-verify the shaft type and diameter. Do not force the knob onto an incompatible shaft.
5. Operation
Once installed, the Tolxh HF-919B D-Shaft Timer Knob functions identically to the original knob. Rotate the knob to set the desired cooking time on your air fryer. The knob provides a tactile interface for adjusting the timer.
6. Maintenance
To maintain the appearance and functionality of your replacement timer knob:
- Clean the knob with a soft, damp cloth.
- Avoid using abrasive cleaners or harsh chemicals, as these can damage the plastic material.
- Ensure the knob is dry before operating the air fryer.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Knob does not fit the shaft. | Incorrect shaft type (not D-shaped) or incorrect shaft diameter. | Verify your air fryer's shaft is a 6mm D-shaped type. This knob is not compatible with pin-type shafts. |
| Knob feels loose after installation. | Knob not fully seated on the shaft. | Gently push the knob further onto the shaft until it is secure. Ensure proper alignment with the D-shape. |
| Air fryer timer does not function after knob replacement. | Issue with the air fryer's internal timer mechanism, not the knob itself. | This replacement part is a knob only. If the timer mechanism is faulty, the air fryer may require professional repair or replacement of the timer component. |
