How to Fix / Troubleshooting
Safety: Unplug the microwave before accessing any internal sensors.
User-level steps:
- 1. Clean interior surfaces: Grease and residue can affect sensor readings. Thoroughly clean the cavity, especially around any sensor grills or covers.
- 2. Avoid covering sensors: Ensure cookware or food does not block sensor openings during auto programs.
- 3. Reset the unit: Unplug for 5–10 minutes to reset the control electronics, then try an auto program with a typical load as described in the manual.
Technician-level steps:
- 4. Inspect sensor wiring: Check the harness from the humidity/weight sensor to the control PCB for damage or loose connectors.
- 5. Replace faulty sensor: If manual modes work but auto modes consistently fail, replace the relevant sensor with a Sage-compatible part.
If errors persist after cleaning and reset, professional diagnosis is recommended.
