Common causes of commercial range burner not working
Clogged Burner Ports
importantCan DIY checkFood debris, grease, or mineral deposits can block the small holes (ports) where gas escapes to form the flame. This prevents proper gas flow and ignition.
Faulty Igniter or Spark Module
importantPro recommendedThe igniter creates a spark to light the gas, and the spark module controls this process. If either fails, the burner won't light.
Gas Supply Issue
criticalPro recommendedThe burner may not be receiving enough gas. This could be due to a partially closed gas valve, a problem with the main gas line, or low pressure from the utility.
Defective Gas Valve
criticalPro recommendedEach burner has a valve that controls gas flow. If this valve is stuck, dirty, or broken, it won't allow gas to reach the burner.
Improper Air/Gas Mixture
minorCan DIY checkThe air shutter, which controls the mix of air and gas, might be misadjusted. This can lead to a weak flame, yellow flame, or no ignition.
Quick checks you can run safely
- 1
Check Other Burners
See if other burners on the range are working correctly. If all burners are out, it strongly suggests a problem with the main gas supply.
- 2
Inspect Burner Ports
Carefully examine the burner ports for any visible blockages like food particles or grease. Ensure all ports are clear.
Safety: Ensure the range is completely cool before touching the burner assembly. - 3
Clean the Burner Assembly
If ports are blocked, gently clean them with a thin wire or needle. Remove the burner cap and head (if possible) and clean thoroughly.
Safety: Ensure the range is completely cool and the gas supply is turned off to the unit before attempting to clean. - 4
Verify Igniter Spark
Turn the burner knob to the 'light' or 'ignite' position and listen/look for a spark. If there's no spark, the igniter or spark module may be faulty.
Safety: Be cautious of moving parts and electrical components. - 5
Check Air Shutter (if accessible)
Locate the air shutter (usually a small adjustable ring near the gas orifice) and ensure it's not completely closed off or obstructed.
Safety: Only attempt this if you can easily access the air shutter without disassembling major components. Ensure the unit is cool.
When to call a pro right away
Multiple burners are not working
This often indicates a problem with the main gas supply to the appliance, which requires professional diagnosis and repair to prevent gas leaks or fire hazards.
You smell gas
This is a critical safety hazard. Immediately turn off the gas supply if possible, ventilate the area, and evacuate. Do not operate any electrical switches or appliances. Call for professional service from a safe location.
Burner ignites but flame is yellow or weak
This suggests an incorrect air-to-gas mixture or low gas pressure, which can lead to inefficient cooking, carbon monoxide production, or incomplete combustion. It requires professional adjustment or repair.
No spark is produced by the igniter
A faulty igniter or spark module requires specialized tools and knowledge to diagnose and replace safely, involving electrical components and gas lines.

How our repair process works
Five steps from your first call to the warranty receipt. No surprises.
- 1
Inspection
Your technician examines the appliance, listens to your description, and notes the model + serial for parts lookup. Visual + audio-based diagnostics first — non-invasive.
- 2
Diagnostics
Targeted tests on the failing subsystem (compressor, control board, heating element, motor, etc.) to identify the exact root cause. You get a clear explanation, not jargon.
- 3
Fix decision
Up-front estimate before any work begins: cost, parts, and the realistic likelihood of success vs. recommending replacement on an old or uneconomical unit. You decide.
- 4
Operational test
After the repair we run the appliance through its normal cycle on-site — never "it should work now, call us if it doesn't." You sign off when it's actually working.
- 5
Warranty + consultation
Receipt with warranty terms in writing. Plus a quick walkthrough of how to extend the appliance's life (filter cleaning, drain maintenance, etc.) — included free.
