What it is
The MCB2105 is an air pressure switch manufactured by Morco Products. It is used on the FEB-24E family of gas boilers, where it monitors the pressure produced by the combustion fan and proves airflow before the boiler is allowed to fire. The switch is also referenced under the manufacturer code N49G006M4.
Signs this part needs replacing
- The fan runs but the boiler does not fire and locks out.
- Repeated lockouts on start-up that clear only after a reset.
- Intermittent ignition, with the boiler firing on some attempts and not others.
- The boiler shuts down mid-cycle once the fan has started.
- No change in boiler behaviour when the fan pressure tubing is checked and confirmed clear.
Before you order
- Confirm your appliance model against the fit list above.
- Check the part number on the existing switch before ordering.
- Inspect the pressure sensing tubing and its connections for blockages or splits, as these can produce the same symptoms as a failed switch.
- Confirm the appliance is a Morco Products FEB-24E series unit, as the switch is listed for this family only.
