DCS Grills TEMP-HIGH Error: Grill overheating
The dcs grills error code temp-high indicates Grill overheating. This guide covers symptoms, diagnostic steps, and repair options. DCS Grill Running Too Hot Before assuming a mechanical fault, verify the temperature with an independent thermometer placed directly on the cooking grate. The dome thermometer on most gas grills — including DCS models — reads the […]

Answer to continue safely
Is it safe to keep using?
No. Do not continue using a grill that cannot maintain safe operating temperatures. Turn off all burners and allow the grill to cool completely before investigating the cause.
Can I reset the code?
No. No reset applies — the root cause must be identified and corrected before the grill is used again.
When to stop immediately?
Stop if you notice: Flames visible outside the firebox or above the lid while closed, Grill continues producing extreme heat with all knobs in OFF position.
Symptoms You May Notice
Lid thermometer reads above 600°F at medium setting
The built-in dome thermometer shows temperatures well above the expected range for the current burner knob positions.
Food burns on outside before cooking through
Exterior of food chars rapidly even at the lowest burner settings, indicating heat output far above the intended level.
Grill will not cool down at lower settings
Reducing all burners to low does not produce a corresponding drop in dome temperature within a normal 5–10 minute window.
Exterior surfaces unusually hot to approach
The outer cart surfaces or side shelves are significantly hotter than normal during cooking, suggesting heat is not contained within the firebox.
Possible Causes
Lid thermometer reading inaccurately
Dome thermometers on gas grills are notorious for inaccuracy. The thermometer itself may have drifted high, not the actual cooking temperature.
DIY PossibleGrease fire in firebox
Heavy grease accumulation on briquettes, flame tamers, or the firebox floor has ignited, producing heat well beyond normal burner output.
DIY PossibleBurner valve stuck open or damaged
A gas valve that will not reduce below full-open position causes continuously high BTU output regardless of knob position.
Requires ProfessionalSafe Checks You Can Do
-
1
Verify with an independent thermometer
Place a separate oven or grill thermometer on the cooking grate and compare its reading to the lid gauge at the same time. Dome thermometers often read 50–100°F higher than grate-level temperature.
If the independent thermometer reads normally, the dome gauge needs recalibration or replacement — not a safety concern.

Check for a grease fire
If all burners are on low and temperatures remain extreme, turn all knobs to OFF and check whether flames continue inside the firebox. A grease fire will continue burning briefly after gas is shut off.
To extinguish a grease fire in the grill: close the lid and keep all knobs off. Starving the fire of oxygen extinguishes it safely. Never use water.
When to Call a Professional
Contact a qualified technician if:
- Temperature confirmed high by independent thermometer at low settings
- Gas valve cannot be reduced below high output at any knob position
- Firebox interior shows heat damage beyond normal cooking discoloration
