Possible Causes

How to Fix / Troubleshooting
Safety: Ensure the circuit is de-energized before opening the electrical compartment.
Steps:
- Check external power: Verify that the circuit breaker or fused spur supplying the Sime heater is ON and not tripped.
- Test outlet: If plugged in, test the outlet with another device.
- Inspect internal fuse: Remove the front cover and locate the PCB fuse. If blown, replace only with the same type and rating. If it blows again, do not continue; there is a deeper fault.
Professional help: If power is present but the unit remains dead, the main PCB or power supply section likely needs replacement by a technician.
