Commercial Range Burner Won't Ignite
Here's what typically causes this, and why an on-site diagnostic — not a phone guess — is what gets you an accurate estimate.
Igniter or Spark Module
Component failure preventing ignition.
Clogged Burner Port
Debris blocking gas flow.
Gas Valve Issue
Valve not opening properly for that burner.
Why diagnosis matters: A symptom like this can trace back to several different root causes, and the fix — and its cost — depends entirely on which one it is. Roxly doesn't quote a repair price over the phone based on a symptom alone: a technician inspects the equipment on site, tests the likely components, and confirms the actual cause before giving you a firm estimate. That's what makes the quote accurate instead of a guess you find out is wrong after the work starts.
Is it safe to keep lighting it manually?
Manual lighting of a gas burner isn't recommended — have it diagnosed rather than working around the issue.
Is this usually one burner or the whole range?
Often isolated to one burner's igniter or port, though a gas valve issue can affect multiple burners.
