🔥 Lynx BBQ Glow Bar Not Shutting Off? How It Works & Easy Fixes
Lynx Professional BBQ grills are known for premium quality, and one of their standout features is the hot surface ignition system, commonly referred to as a glow bar. This system makes lighting the grill fast, wind-resistant, and spark-free.
However, some users experience a common issue: the glow bar doesn’t shut off even after the burners ignite. In this article, Advance Appliance Ltd explains how the system works, why this issue occurs, and what you can do to fix it.
✅ How the Glow Bar Ignition System Works
- Press and hold the burner knob – This sends electricity to the glow bar, causing it to heat up rapidly.
- The glow bar glows bright orange – It reaches temperatures high enough to ignite gas.
- Turn the knob to “Lite” – This releases gas from the burner, which is ignited by the hot glow bar.
- The burner ignites instantly – At this point, the glow bar’s job is done.
- The system shuts off the glow bar automatically – This prevents overheating and conserves energy.
- You hold the knob a bit longer to let the thermocouple detect the flame and keep the gas flowing safely.
This system is generally very reliable. However, if something disrupts the ignition feedback loop, the glow bar may remain powered indefinitely — which is not how the system is supposed to work.
⚠️ Why the Glow Bar Might Stay On
If your burner lights up, but the glow bar stays on, it means something in the system isn’t registering that the flame has successfully ignited. It could be an issue with the sensors, control board, or wiring.
🛠️ Common Causes & Fixes
| Cause | Description | Fix |
|---|---|---|
| Faulty Ignition Module | The control board doesn’t stop sending power to the glow bar after ignition | Replace the ignition module |
| Defective Thermocouple | Fails to sense the flame, so it doesn’t trigger shutoff | Replace or reposition the thermocouple near the flame |
| Wiring Short / Moisture | Water or corrosion keeps the glow bar powered | Inspect and replace damaged wires; dry out connections |
| Control Knob Stuck | Internal switch doesn’t disengage ignition circuit | Clean or replace knob mechanism |
| Poor Grounding | Feedback signal is lost or blocked | Check, tighten, and clean ground wires |
🔎 Signs Your Glow Bar Isn’t Shutting Off Properly
- Glow bar stays red hot even after burner is lit
- You hear a constant electrical humming
- Burners ignite normally, but the grill doesn’t switch to standard operation
- Thermocouple doesn’t engage, causing gas shutoff after releasing knob
👨🔧 Expert Advice from Advance Appliance Ltd
In most cases, the issue is with either the ignition module or the thermocouple. The glow bar itself rarely fails unless physically damaged or overworked due to another component malfunctioning.
Technicians often start by inspecting the thermocouple’s position and testing it with a multimeter. If that checks out, the next step is to test voltage output from the ignition control board and inspect for corrosion or loose wires.
If your Lynx grill is still under warranty, consider contacting Lynx support or an authorized service provider. If not, Advance Appliance Ltd offers professional appliance diagnostics and repair services across Edmonton, Calgary, and Red Deer.
✅ What You Can Try Before Calling a Technician
- Turn off the grill’s power and wait 5–10 minutes, then restart
- Clean any visible debris or grease near the burner and thermocouple
- Ensure no water is present in the control compartment
- Test another burner to see if the issue is isolated
If the problem continues, it’s best to leave further inspection to a trained technician, as improper handling of grill wiring or gas components can be dangerous.
💡 Final Thoughts
The glow bar ignition system in a Lynx BBQ is one of the most reliable systems in premium outdoor grills. But like any component, it needs to receive the right signals to turn on and off properly.
Whether you’re troubleshooting at home or seeking professional help, understanding how the system works gives you the advantage of catching problems early and avoiding costly repairs.
