• Typical duration: 2 – 4 hours depending on the fault diagnosis and part replacement.
Safety First
• Always disconnect power before commencing any repairs.
• Use proper personal protective equipment, such as gloves and eye protection.
• Verify that no residual charge remains in the capacitor circuit.
• Follow manufacturer guidelines for servicing and part replacement.
Tools & Materials
Item | Purpose |
|---|---|
Digital multimeter | Diagnose electrical faults and check continuity. |
Replacement parts | Faulty components such as thermostats or heating elements. |
Cleaning supplies | Non-abrasive cleaners and cloths to remove dust and grime. |
Screwdrivers and pliers | For disassembling components and tightening connections. |
Step-by-Step
1. Disconnect the radiator from the mains supply and allow it to cool.
2. Remove the front cover and inspect for dust build-up, corrosion or loose connections.
3. Clean the internal components using a non-abrasive cleaner and cloth.
4. Use a digital multimeter to test for continuity and identify any electrical faults.
5. Replace any defective components such as heating elements or thermostats as required.
6. Reassemble the radiator, ensuring all connections are secure.
7. Test the unit after reconnection to confirm proper operation and even heat distribution.
Completion Checks
• Radiator operates steadily without error codes and heats evenly throughout.
• All electrical tests have passed and there are no visible faults or leakage.
• Service records are updated and the unit is safe for regular use.
• Final functionality check confirms proper thermostat response and even heat distribution.
When to Call a Pro Instead
If extensive electrical faults, complex wiring issues or persistent malfunctioning are observed, it is advisable to consult a NICEIC-registered electrician or experienced heating engineer to ensure safety and regulatory compliance.
