What it is
The Morco Products MRS0300 is an air pressure switch, supplied under the product name Air Pressure Switch Blue 150/135. It forms part of the safety and operating sequence on Morco F11-E and F11-EL appliances, monitoring air pressure and providing a switching signal to the appliance control circuit.
Signs this part needs replacing
- The appliance fails to fire or drops into lockout with the fan running.
- The ignition sequence begins but the appliance cuts out shortly afterwards.
- Repeated lockouts that clear on reset but return during use.
- The fan runs continuously without the appliance progressing to ignition.
- Intermittent operation that cannot be traced to another component.
Before you order
- Confirm the appliance model is F11-E or F11-EL.
- Check the existing switch part number and colour marking against the item listed.
- Inspect the pressure sensing tubes and their connections for blockage, kinking or poor fit, as these can mimic a failed switch.
