What it is
The Johnson & Starley S00076 is an air flow sensor, also referred to as a mass air flow (MAF) sensor, listed in the Thermostats & Thermistors section of the Johnson & Starley spares range. It measures the volume and speed of air passing through the appliance and returns that signal to the control board, which uses it to manage fan operation, combustion and safe shutdown. The same sensor is used across the Balmforth/Mclary warm air unit family and a number of other Johnson & Starley appliances.
Signs this part needs replacing
- The appliance locks out or fails to fire shortly after the fan starts
- Intermittent ignition faults or unexplained shutdowns during a heating cycle
- The fan runs continuously, hunts, or runs at a speed that does not match demand
- Combustion readings drift outside the expected range with no other obvious cause
- Control board fault codes relating to air flow or fan feedback
Before you order
- Check the GC number on the appliance data badge against the compatibility list, as the same part number is used across many models.
- Confirm the sensor currently fitted carries S00076 or the earlier number BOS01245.
