Glow-worm Micron 60FF 70FF 80FF Boiler PCB 2000801991 Was S227031
Product Overview
The Glow-worm Micron Boiler Printed Circuit Board (PCB) (Part Number: 2000801991) is a replacement electronic control component designed for selected Glow-worm heating systems.
Part number 2000801991 is identified as a TPO (Timed Pump Overrun) Printed Circuit Board, replacing the earlier part number S227031.
The PCB forms part of the boiler's electronic control system, processing signals from connected components and supporting the control and monitoring of appliance operation.
The timed pump overrun function allows the heating circulation pump to continue operating for a controlled period after burner operation has stopped, helping to dissipate residual heat from the boiler.
ℹ️ Product Condition Options:
This part may be available in New or Refurbished condition. Please select your desired option from the dropdown menu above. Refurbished parts should be professionally inspected and tested to confirm correct operation before installation.
Technical Insight & Common Failure Symptoms
The Printed Circuit Board is an electronic control component responsible for processing electrical signals and coordinating functions within the boiler's operating sequence.
The TPO PCB also supports timed pump overrun operation, allowing continued water circulation after the burner switches off.
Over time, PCB performance may be affected by electronic component deterioration, damaged connections or electrical faults.
Possible symptoms that may indicate a PCB or associated electrical system problem include:
-
Boiler failing to start or operate correctly.
-
Intermittent boiler operation.
-
Boiler failing to respond to heating demand.
-
Unexpected boiler shutdowns or lockouts.
-
Ignition sequence failing to complete.
-
Heating circulation pump not operating as expected during the pump overrun sequence.
-
Electrical or control-related faults.
These symptoms do not necessarily confirm a faulty PCB, as similar problems may result from wiring, sensors, switches, electrical connections or other boiler components. Correct professional diagnosis should be carried out before replacement.
Compatibility
This part (MPN: 2000801991, Previous Reference: S227031) is associated with selected Glow-worm Micron 60FF, 70FF and 80FF boiler systems.
Please verify the exact boiler model, GC number, original PCB reference, circuit board version and electrical connections against the manufacturer's technical documentation before ordering to ensure correct fitment.
Safety Advice
Boiler PCBs and associated electrical control components should only be diagnosed, removed or installed by a suitably qualified and competent heating engineer.
Always isolate the appliance's electrical supply before carrying out any work and follow the manufacturer's installation and servicing instructions. Appropriate electrical, control, pump operation and appliance safety checks must be completed before the boiler is returned to service.
