What it is
The Grant MPCBS62/A is a low pressure switch upgrade kit supplied as a retrofit assembly for internal models. It forms part of the boiler's pressure monitoring circuit, where the switch signals the control system when system pressure falls outside the operating range. The kit is intended for fitting to existing Grant appliances as an upgrade rather than a like-for-like swap.
Signs this part needs replacing
- Boiler fails to fire or drops into lockout when demand is present
- Intermittent operation, with the boiler running only when pressure is at the top of its range
- Repeated lockouts that clear after pressure is topped up
- Boiler shutting down shortly after ignition despite adequate system pressure
- Fault code or diagnostic indication pointing to the pressure switch circuit
Before you order
- Confirm your appliance model against the fit list above, as this kit covers internal models only
- Check whether your boiler already has the upgraded switch fitted, to avoid duplicate work
- Have the appliance's model and serial details to hand when cross-checking against the manufacturer's parts list
- Confirm the existing switch wiring and mounting arrangement match the retrofit kit before starting the job
