Possible Causes
Aging magnetron with reduced emission, low mains voltage, failing high-voltage capacitor, partial obstruction in waveguide
How to Fix / Troubleshooting
Safety: Use caution when testing with hot water.
Steps to evaluate slow heating:
- 1. Perform a water test: Heat 250 ml of room-temperature water on full power for 1 minute. Compare the temperature rise to the performance specified in the Sage manual.
- 2. Check power setting: Ensure the power level is set to 100% and not a lower setting or defrost mode.
- 3. Verify supply voltage: If possible, have an electrician check that the outlet voltage is within specification under load.
If the microwave consistently underheats despite correct settings and supply, the magnetron or high-voltage components may be degrading and should be replaced by a technician.
