Baxi Bermuda 51/5 Inset 3 50/5 50/6 Boiler Potentiometer Assembly 5107803

Product Overview

The Baxi Bermuda Boiler Potentiometer Assembly (Part Number: 5107803) is an electrical control component associated with selected Baxi Bermuda heating systems.

A potentiometer is a variable-resistance component used to provide an adjustable electrical signal within a control circuit. In a boiler control assembly, it can allow a setting to be adjusted and communicated to the associated controls.

Correct operation of the potentiometer assembly is important for maintaining the intended response of the control system.

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 components should be professionally inspected and electrically tested to confirm correct operation before installation.

Technical Insight & Common Failure Symptoms

The potentiometer assembly operates by varying electrical resistance as its adjustment mechanism is moved. This change can be used by the associated electronic control circuit to interpret a selected setting.

Over time, potentiometer performance may be affected by worn internal contacts, mechanical deterioration, damaged connections or electrical faults.

Possible symptoms that may indicate a potentiometer or associated control component problem include:

• Boiler controls failing to respond correctly to adjustment.

• Intermittent response when changing a control setting.

• Difficulty maintaining the selected control setting.

• Adjustment mechanism becoming stiff, loose or damaged.

• Irregular electrical response from the potentiometer.

• Visible damage or deterioration affecting the assembly.

• Electrical connection or control-related faults.

These symptoms do not necessarily confirm a faulty potentiometer assembly, as similar problems may result from wiring, electrical connections or other boiler control components. Correct professional diagnosis should be carried out before replacement.

Compatibility

This part (MPN: 5107803) is associated with selected Baxi Bermuda boiler systems.

Please verify the exact boiler model, GC number, part number, potentiometer configuration and electrical connections against the manufacturer's technical documentation before ordering to ensure correct fitment.

Safety Advice

Boiler potentiometer assemblies and associated electrical control components should only be inspected, 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 servicing instructions. Where work involves gas appliance controls, a Gas Safe registered engineer with the appropriate qualifications must carry out the work. All required electrical, control and operational safety checks must be completed before the appliance is returned to service.
