Safety Warning
This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.
If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.
Possible Causes
How to Fix / Troubleshooting
Critical safety: Internal high-voltage components can be lethal. Do not open the cabinet unless you are trained and know how to discharge the capacitor safely.
User-level checks:
- 1. Confirm symptom: Place a cup of water in the Salter microwave and run on full power for 1–2 minutes. If the water remains cold and the unit sounds normal, heating has failed.
- 2. Check power level settings: Ensure the power level is set to 100% (High) and not to a low setting or defrost mode.
- 3. Try different containers: Use a microwave-safe glass or ceramic container. Metal-trimmed dishes can prevent heating.
- 4. Power reset: Unplug for 10 minutes, then test again.
If there is still no heat, the fault is almost certainly in the high-voltage system (magnetron, transformer, capacitor, or diode) and requires professional diagnosis and replacement of the defective component.
