What it is
The 2000802664 is the gas control valve fitted to a range of Glow-worm combination and system boilers. It sits between the gas supply and the burner: when the appliance calls for heat, the printed circuit board sends a signal to the valve, which opens to let gas flow through to the pilot assembly or main burner. It is the current part number, having replaced the earlier 801649.
Signs this part needs replacing
- Boiler locks out with a gas valve or ignition fault code
- No gas reaching the burner despite the pilot/ignition sequence running
- Burner lights intermittently or fails to modulate correctly
- Valve fails to close, or is heard buzzing/chattering
Before you order
- Match the part number printed on your existing valve, or check against 801649 if you have the older part
- Isolate the gas supply and electrical power before removal
