A gas grill that gets too hot can turn your perfect BBQ into a charred disaster. Whether your grill won’t cool down or has sudden temperature spikes, several issues could be causing the problem. In this guide, we’ll cover the most common reasons your grill is overheating and how to fix them.
Why Is My Gas Grill Overheating?
If your grill is burning hotter than usual, check these possible culprits:
1. Reset or Replace the Regulator
The regulator controls gas pressure from the propane tank. If it fails, your grill may burn way too hot.
Signs of a Bad Regulator:
- Flames stay high even on low settings
- Sudden temperature surges
- Hissing or irregular gas flow
How to Fix It:
-
Reset the regulator – Turn off the grill, disconnect the propane tank, wait 30 seconds, then reconnect.
-
Test with a different tank – Rule out propane supply issues.
- Replace the regulator – If resetting doesn’t work, install a new one.
2. Clean or Replace Clogged Burners
Blocked burner tubes disrupt gas flow, creating uneven heat and hot spots.
- Turn off gas & disconnect the propane tank.
- Remove grates and heat shields to access burners.
- Check for blockages (spider webs, grease, debris).
- Clean ports with a wire brush or pipe cleaner.
- Reassemble and test the grill.
If burners are corroded or damaged, replace them.
3. Check Control Valves
If adjusting the knobs doesn’t change the flame height, the valves may be faulty.
How to Test Control Valves:
- Turn the knob from High → Low – The flame should decrease smoothly.
- If the flame stays high, the valve may need replacement.
Tip: Consult your grill’s manual for compatible replacement parts.
4. Adjust for Wind & Ventilation
Wind can increase airflow, making the grill burn hotter.
Quick Fixes:
- Use a wind guard or move the grill to a sheltered spot.
- Adjust the grill’s vents (if available) to control airflow.
- Lower the gas slightly to compensate for wind.
5. Remove Excess Grease
Grease buildup traps heat and can cause dangerous flare-ups.
How to Clean Your Grill:
- Scrape grease from the drip tray and burners.
- Brush off debris from grates and interior surfaces.
- Empty the grease trap regularly.
Pro Tips to Prevent Overheating
- Preheat properly – Let the grill stabilize before cooking.
- Use a grill thermometer – Monitor temps accurately.
- Don’t overcrowd the grill – Good airflow helps regulate heat.
An overheating grill can ruin your BBQ, but most fixes are simple. By checking the regulator, burners, valves, and grease buildup, you can get your grill back under control.
