Riello Boulter G10 COH 110 220 Burner Motor Capacitor 20087025

Product Overview

The Riello Boulter Burner Motor Capacitor (Part Number: 20087025) is an electrical motor component designed for selected Riello oil burner systems.

Part number 20087025 is identified as a 4µF Motor Capacitor, used to support the starting and operation of the burner's electric motor.

The capacitor forms part of the motor's electrical circuit, helping provide the phase shift required for motor starting and operation.

Correct capacitor performance is important for reliable burner motor operation and the appliance's normal start-up sequence.

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 capacitors should be professionally inspected and electrically tested to confirm correct capacitance, insulation integrity and suitability before installation.

Technical Insight & Common Failure Symptoms

The 4µF motor capacitor is an electrical component used within the burner's motor circuit. It supports the phase relationship required for the motor to start and operate correctly.

Part number 20087025 is also described as a P2 capacitor with moulded connection leads.

Over time, capacitor performance may deteriorate due to electrical ageing, heat exposure or internal component failure.

Possible symptoms that may indicate a motor capacitor or associated electrical problem include:

• Burner motor failing to start.

• Motor humming without rotating correctly.

• Intermittent motor starting problems.

• Motor struggling to reach normal operating speed.

• Burner failing to complete its normal start-up sequence.

• Burner entering a lockout following a failed start.

• Visible damage or deterioration affecting the capacitor or its connections.

These symptoms do not necessarily confirm a faulty capacitor, as similar problems may result from motor faults, electrical supply issues, wiring or other burner components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 20087025) is associated with selected Riello Boulter G10 COH 110 and COH 220 oil burner systems.

Please verify the exact burner model, type number, original capacitor specification, capacitance rating and connection arrangement against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Oil burner motor capacitors and associated electrical components should only be inspected, removed or installed by a suitably qualified and competent oil heating engineer or electrical professional.

Always isolate the appliance's electrical supply before carrying out any work. Capacitors may retain an electrical charge after disconnection and must be handled and discharged using appropriate procedures. Follow the manufacturer's servicing instructions and complete all required electrical, burner operation and combustion safety checks before returning the appliance to service.
