What it is
The Grant MPCBS49XA is a single pole low pressure switch supplied as a Grant Spares component. It monitors pressure within the appliance circuit and signals the control board when pressure drops or flow changes, so the appliance can manage activation and shutdown safely. It is a direct replacement item for the switch fitted at that position.
Signs this part needs replacing
- The appliance fails to fire or repeatedly drops into lockout
- Ignition is intermittent, or the burner shuts down during a demand for heat
- A pressure-related fault code appears on the control panel
- Heating or hot water cuts out shortly after start-up
- Switching behaviour traced to the pressure sensing circuit is erratic or inconsistent
Before you order
- Confirm the part number printed on the existing switch matches MPCBS49XA
- Check the appliance model and serial plate against the compatibility list
- Compare the alternative number SINGLE-POLE-LOW-PRESSURE-SWITCH with any marking on the old component
- Inspect seals and electrical connections on removal and renew any that are worn
