What it is
The Vokera fan wiring harness, part number 20135794, is an electrical lead used on the Unica MAX range of gas boilers. It connects the combustion fan to the appliance control board, carrying power and feedback signals. A secure connection is required for correct fan operation and safe boiler sequencing.
Signs this part needs replacing
- Fan fails to run, runs intermittently, or stops mid-cycle
- Fan-related fault codes or lockouts shown on the boiler display
- Visible damage to the harness, such as chafed, cracked or heat-damaged insulation
- Loose, corroded or discoloured connectors at the fan or control board
- Boiler fails to ignite or repeatedly locks out where fan feedback is suspect
Before you order
- Check the model and GC number on the appliance data badge against the fit list
- Inspect the existing harness for connector type, pin count and lead length
- Confirm the fan fitted to the appliance matches the harness connection
- Isolate the electrical supply before removing or fitting the harness
