STOP USE

What to do first

Stop using the affected fireplace until it has been assessed. For suspected gas, a CO alarm, an active fire, or immediate danger, leave and call 911 from a safe location.

Bring model information and the displayed fault

A gas fireplace's ignition sequence and approved components are model-specific. Note what was visible during the failure, without repeating attempts. Ask whether the service company handles the model and whether the diagnostic charge includes a written finding or only the initial visit.

What the inspection should resolve

Ask for the cause, supporting photographs, limitations of the inspection, and a written recommendation about continued use. A repair quote should identify the affected parts and the reason for the proposed work.

THE SHORT ANSWER

Leave a malfunctioning gas fireplace unused and arrange model-specific diagnosis. If gas is suspected, leave and contact emergency help from a safe location.

Updated September 10, 2026

What you can observe safely

  • Record an error message if it is visible without opening the unit.
  • Locate the model in your manual.

What to avoid

  • Do not climb onto the roof or enter the chimney.
  • Do not alter gas components, venting, or safety controls.
  • Do not use a test fire to diagnose the problem.

Possible causes to assess

  • Ignition or control fault
  • Power or system issue
  • A safety device stopping operation

A symptom cannot establish the cause remotely. An assessment of the complete system helps determine the appropriate repair.

A few common questions

Can this be diagnosed from a photo?

A photo can document a symptom and help prepare a visit. It cannot confirm concealed conditions or establish that a chimney or fuel-burning appliance is safe.
