This Bonaire Vulcan gas heater flame sensor is a critical spare part for HVAC techs and competent DIYers, ensuring your heating system ignites reliably. In the cooler Australian months, you need your ducted gas heater running right, and a faulty flame sensor can stop it dead.
I've seen plenty of nuisance call-outs just because a flame sensor was gunked up or had a weak signal; replacing it often sorts out intermittent ignition faults.
This flame sensor is a direct replacement for Bonaire Vulcan gas heaters that require a 50mm long, "new style" flame sensor. It corresponds to Bonaire part number 5121605SP. If you're running a different model, check fittings and specs before ordering.
| Specification | Detail |
|---|---|
| Part Number (Bonaire PN) | 5121605SP |
| Probe Length | 50mm |
| Type | Flame Sensor Probe (New Style) |
Before you swap out a flame sensor, give the old one a good clean with some fine steel wool. Sometimes, carbon build-up is all that's stopping it from doing its job, saving you a trip or a new part.
Pair with gas leak detection fluid, a quality multimeter, and a pressure gauge for comprehensive diagnostics when troubleshooting gas heater issues.
