By restricting the air intake to the fan, the low air pressure cut-off should open the boiler control circuit, shutting the boiler down. Testing Flame Safeguard Devices To test the flame safeguard device, simulate a flame failure condition. This article is adapted
To test a fan speed resistor: Electrically isolate boiler / system controls. Remove leads from resistor. Set multimeter on ohms scale for resistance readings, across resistor connections: No resistance/infinity = faulty. Resistance reading (may vary) = ok. A bad connection will increase resistance and as a result may drop the fan speed
