Possible Causes
Failed inverter board, Loose inverter connectors, Overheated inverter module, Faulty magnetron current sensing
How to Fix / Troubleshooting
Safety first: Unplug the microwave. Inverter circuits operate at high voltage and high frequency; servicing should be done only by trained personnel.
- Step 1 – Power reset: Disconnect for 10–15 minutes, then reconnect and test. Transient faults may clear.
- Step 2 – Check cooling: Ensure vents are clear and the cooling fan is operating, as inverter modules are sensitive to overheating.
- Step 3 – Visual inspection: With the cabinet removed, inspect the inverter board for burnt components or bulging capacitors. Do not touch the board while powered.
- Step 4 – Professional replacement: If E16 persists, the inverter module or magnetron current sensing circuit likely needs replacement by a Severin service center.
