How to Fix / Troubleshooting
Safety first: Only qualified electricians should work on mains wiring. Isolate the appliance before inspection.
- Check supply: Measure mains voltage and frequency at the furnace connection. Ensure it matches the rating plate.
- Inspect wiring: Verify correct live, neutral, and earth connections at the terminal block. Tighten any loose screws.
- Dedicated circuit: Ensure the furnace is on a dedicated circuit and not sharing with heavy inductive loads that may cause interference.
- Surge protection: Consider installing surge protection if the supply is known to be unstable.
- PCB replacement: If supply is stable but E16 persists, the internal power supply on the PCB may be defective and require replacement.
