Bradford White Blower Fault: Combustion-Blower Fault
What the Bradford White Blower Fault fault means, what causes it, and why it's a job for a licensed BC gas technician — not a DIY reset.
Severity
High — needs prompt professional attention
Gas safety first
This fault involves gas, combustion or venting. If you smell gas (rotten-egg odour), hear hissing, or feel unwell, leave the building immediately and call 911 or FortisBC at 1-800-663-9911 from outside. Do not flip switches or relight anything. For all other cases, switch the boiler off and call a licensed gas technician.
What the Bradford White Blower Fault fault means
The combustion blower is not running at the required speed, so ignition is blocked.
On Bradford White Brute Elite condensing series, Blower Fault is a combustion-fan fault. It is a protective response — the boiler is telling you something needs attention, and the safe, lasting fix is a proper diagnosis rather than repeated resets.
Symptoms you may notice
- No heat or hot water
- Boiler will not begin its ignition sequence
- Unusual fan noise or no fan sound at all
Common causes of Bradford White Blower Fault
Why this is not a DIY fix
The combustion fan controls the air–gas ratio. A fan or fan-speed-feedback fault means the boiler cannot prove safe airflow, so it (correctly) refuses to fire. Replacing and re-commissioning the fan involves combustion verification — licensed gas work.
In British Columbia, gas work must be performed by a TSBC-licensed gas fitter. GasBoilers.ca — a CanroHeat division — sends Red Seal–certified, gas-licensed technicians who diagnose the true cause, repair it correctly, and verify safe operation before they leave.
