What it is
The electronics module (MAF) is a control board supplied by Johnson & Starley for its Hispec Ju55 warm air unit and Ju40-55 appliances. It handles the electronic sequencing and monitoring functions of the appliance, including fan and ignition control. The module is identified by the MAF designation on the manufacturer's parts listing.
Signs this part needs replacing
- The appliance fails to ignite or runs through its start sequence without firing
- The fan does not run, or runs continuously without modulating
- Repeated lockouts or fault codes that clear only on a power reset
- No response to the room thermostat or programmer
- Erratic or intermittent operation that cannot be traced to gas, air or thermostat faults
Before you order
- Check the model and GC number on the appliance rating plate against the fitment list above
- Confirm the existing module is marked MAF before ordering
- Inspect the wiring harness and plug connections for damage, as faults here can mimic module failure
- Isolate the electrical supply before removing or fitting the module
