What Causes Burner Assembly Failure

Understanding the root cause helps determine whether repair or replacement is the best option.

Ignition System Failure

common

Igniter, spark electrode, or hot surface igniter has worn out or failed.

Flame Sensor Contamination

common

Flame rod is coated with residue, preventing proper flame detection.

Gas Valve Malfunction

occasional

Gas valve not opening fully or at all due to coil failure or mechanical issues.

Control Board Failure

occasional

Burner controller or ignition module has failed electronically.

Combustion Air Issues

occasional

Insufficient combustion air due to blocked intake or improper setup.

Repair vs. Replace Decision Guide

Repair When...

Igniter or flame sensor needs replacement
Gas valve can be rebuilt or replaced individually
Control board is available and cost-effective
Burner is less than 15 years old

Replace When...

Heat exchanger is cracked or severely corroded
Burner is 20+ years old with multiple failures
Parts are obsolete or unavailable
Energy efficiency upgrade is desired
Capacity increase is needed

Cost Comparison

Repairs typically $300-1,500. Complete burner replacement $5,000-15,000 depending on size and type.

Lifespan Considerations

A well-maintained burner lasts 15-25 years. If facing major repairs on 15+ year equipment, replacement often makes sense.

Burner Assembly Service FAQ

Common questions about burner assembly repair and replacement

Burners should be inspected and serviced at least annually, ideally before the heating season. High-use facilities may benefit from semi-annual service. Regular maintenance prevents unexpected failures and maintains efficiency.

Repeated lockout is usually caused by a dirty or failing flame sensor, weak ignition, low gas pressure, or combustion air issues. Don't just reset it repeatedly—have the root cause diagnosed to prevent damage and safety hazards.

Yes, most burners can be converted with the proper conversion kit. This involves changing orifices, adjusting gas pressure regulators, and recalibrating. WERCS can perform this conversion and ensure proper operation.
