What it is
The Hamworthy LMU64 programmer, part number 533901498, is a control unit for the WM150 NG boiler. It manages the boiler's operating sequence as part of the appliance's control and timing arrangement. It is supplied as a Hamworthy spare part.
Signs this part needs replacing
- The boiler fails to run through its start-up sequence or does not fire at all.
- The appliance repeatedly locks out, with the fault returning after a reset.
- Operation is intermittent, with the boiler cutting out without an obvious external cause.
- Fault codes relating to the control or sequencing of the appliance are displayed.
- The boiler no longer responds to demand from the programmer or controls.
Before you order
- Confirm the appliance model is the WM150 NG.
- Check the existing control unit's part number against 533901498 before removal.
- Isolate the electrical supply to the boiler before any work begins.
- Verify the fault lies with the control unit rather than the wiring, sensors or gas supply.
