What it is
This is a thermocouple with sensor supplied by Morco Products for use in the D61B and D61E gas boiler range. It sits in the pilot flame path and generates the small voltage that holds the gas valve open while a flame is proven. The part is listed under the manufacturer reference FW0301.
Signs this part needs replacing
- The pilot flame goes out as soon as the gas valve button is released
- The boiler lights but shuts down shortly after the burner establishes
- Flame failure lockout occurs repeatedly, with no other obvious cause
- The pilot flame is present but the burner will not stay alight during a call for heat
Before you order
- Confirm the appliance is a Morco D61B or D61E before ordering
- Compare the existing thermocouple and its sensor against the FW0301 reference
- Inspect the pilot assembly and flame path for debris or damage, as these can mimic thermocouple failure
- Check that the connection at the gas valve is sound and undamaged
