Tradie Pro Tip
"When replacing a combustion fan, it's a good time to inspect the ignitor, flame sensor, and pressure switch too. Often, a failing fan puts extra strain on these components, or their failure contributes to the fan's demise."
Pair With
Consider pairing with replacement ignitors, flame sensors, or pressure switches for Braemar gas heaters. A quality multimeter can also be handy for diagnosing electrical faults during the repair process.
