This knob is an equivalent replacement for part numbers PA010034, VKNPA010034, AP5315062, and 810722. It is compatible with Viking range models VGIC305-4BSS and VGIC485-6GSS.
4. Installation Instructions
No special tools are required for the installation of this replacement knob. Follow these steps carefully:
- Disconnect Power: Before beginning, ensure your range is completely turned off and disconnected from the power supply to prevent electrical hazards.
- Remove Old Knob: Gently pull the existing knob straight off the burner shaft. If it is stuck, a slight twisting motion may help, but avoid excessive force to prevent damage to the shaft.
- Verify Compatibility: Compare the shaft opening of the new PA010034 knob with your range's burner shaft. The knob is designed for a D-shaped shaft. Also, verify the dimensions and hole direction as shown in the compatibility image below.
- Install New Knob: Align the D-shaped opening of the new PA010034 knob with the D-shaped burner shaft. Push the knob firmly onto the shaft until it is securely seated. Ensure it is fully engaged and does not wobble.
- Restore Power: Once the knob is securely installed, reconnect the range to its power supply.
- Test Functionality: Turn the knob to various settings (LOW, MED, HI, SIMMER) to ensure it rotates smoothly and engages correctly with the burner controls.

5. Operating Instructions
The PA010034 range knob functions identically to the original knob it replaces. To operate a burner:
- Turn On: Push the knob in slightly and rotate it counter-clockwise to the desired heat setting (e.g., HI, MED, LOW, SIMMER). The burner should ignite.
- Adjust Heat: Continue rotating the knob to adjust the flame intensity or heat level as needed.
- Turn Off: Rotate the knob clockwise until it clicks into the "OFF" position. Ensure the burner flame is extinguished.
6. Maintenance and Care
To ensure the longevity and proper function of your Reyhoar PA010034 range knob, follow these simple maintenance guidelines:
- Cleaning: The knob can be easily removed for cleaning. Wipe it with a soft cloth dampened with mild soap and water. Avoid abrasive cleaners or harsh chemicals, as these can damage the finish or markings.
- Drying: Ensure the knob is completely dry before reattaching it to the range shaft.
- Inspection: Periodically inspect the knob for any signs of wear or damage. If the knob becomes loose or difficult to turn, refer to the troubleshooting section or contact support.
7. Troubleshooting
If you encounter any issues with your Reyhoar PA010034 range knob, refer to the table below for common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Knob will not turn or is stiff. | Misalignment with shaft, debris under knob, or damaged shaft. | Remove knob and check for obstructions. Realign and reattach. Inspect range shaft for damage. |
| Knob will not stay on the shaft. | Improper installation, worn D-shaped opening, or damaged range shaft. | Ensure knob is pushed firmly onto the shaft. If the knob's opening is worn, replacement may be necessary. Inspect range shaft for damage. |
| Range will not set/ignite when knob is turned. | Knob not fully engaging the control mechanism, or an issue with the range itself. | Ensure the knob is fully seated and engaging the shaft. If the problem persists, the issue may be with the range's internal components, not the knob. |
If these solutions do not resolve the issue, please contact customer support.
