What it is

The Morco Products MCB3100 is an air pressure switch supplied in pink and marked 120/100. It is a safety-sensing component fitted to the Morco Products FEB-24ED3 appliance, where it monitors air movement through the fan and flue system. The switch proves airflow to the control board before the appliance is allowed to fire.

Signs this part needs replacing

  • The appliance fails to fire and the fan runs without the sequence progressing.
  • Repeated lockouts or ignition faults linked to an airflow or pressure fault code.
  • Intermittent operation that changes when the sensing tubing or switch is disturbed.
  • The switch does not change state when the fan is running and pressure is present.

Before you order

  • Confirm the appliance model is the Morco Products FEB-24ED3 before ordering.
  • Check the marking on the existing switch and compare it with 120/100.
  • Inspect the sensing tubing and connections for splits, blockages or loose fit before assuming the switch itself has failed.
  • Isolate the electrical supply and gas supply before carrying out any work on the appliance.
