Setup and Installation
Replacing your gas range burner knobs is a straightforward process that requires no special tools. Follow these steps for a quick and secure installation:
- Step 1: Remove the Old Knob
Gently pull the old knob off the stove's control shaft horizontally. Ensure the stove is turned off and cool before proceeding. - Step 2: Install the New Knob
Align the replacement knob (DG64-00473A) with the mounting shaft on your stove. Press the knob firmly and directly in line with the shaft until it is securely seated. Do not force it at an angle. - Step 3: Verify Installation
Once installed, gently turn the new knob to ensure it rotates smoothly and engages properly with the stove's controls. Verify that it is firmly attached and does not wobble.

Operating Instructions
These knobs function identically to your original gas range knobs. To operate:
- Turning On: Push the knob inward and rotate it to the "Lite HI" position to ignite the burner.
- Adjusting Flame: Once ignited, rotate the knob between "LO", "MED", and "HI" settings to adjust the flame intensity as needed for cooking.
- Turning Off: Rotate the knob back to the "OFF" position. Ensure the flame is completely extinguished.
Safety Note: Always ensure the burner is completely off when not in use. Do not leave cooking unattended.
Maintenance
To ensure the longevity and optimal performance of your AZ4U gas range burner knobs, follow these simple maintenance guidelines:
- Cleaning: Wipe the knobs regularly with a soft, damp cloth and mild soap. Avoid abrasive cleaners or scouring pads, as these can damage the metal finish.
- Drying: Ensure the knobs are completely dry before reattaching them to the stove.
- Inspection: Periodically check the knobs for any signs of wear or damage. While designed for durability, prompt replacement of severely damaged knobs is recommended for safety.
- Avoid Excessive Force: Do not apply excessive force when turning or pulling the knobs, as this can strain the internal components of the stove or the knob itself.
Troubleshooting
If you encounter any issues with your new AZ4U gas range burner knobs, consider the following common problems and their solutions:
| Symptom | Possible Cause | Solution |
|---|---|---|
| Stove won't start / Burner won't ignite | Knob not fully engaged with the control shaft, or internal stove issue. | Ensure the knob is pushed in completely and aligned correctly. If the issue persists, the problem may lie with the stove's igniter or gas supply, not the knob. |
| Knob feels loose or wobbly | Improper installation or the shaft on the stove is worn. | Remove the knob and re-install, ensuring it is pressed firmly onto the shaft. If it remains loose, verify the stove's shaft is not damaged. |
| Knob is difficult to turn | Debris under the knob or a misaligned shaft. | Remove the knob and clean any debris from the shaft and the knob's interior. Re-install carefully. If the issue persists, the stove's valve may be stiff. |
| Knob is damaged (e.g., cracked) | Physical impact or extreme force. | Replace the damaged knob with a new one. These metal knobs are designed to be highly durable against cracking. |
