Microwave displays E14 and may shut down unexpectedly during operation.

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

Blocked cooling vents, Failed internal thermal cut-out on chassis, Overheating transformer, Fan not running at correct speed

Safety: Unplug and allow the microwave to cool fully.

Clear vents: Move the microwave to ensure adequate clearance on all sides. Clean dust and grease from all external vents.
Avoid enclosed cabinets: Do not operate the Princess microwave in a tightly enclosed space without ventilation.
Test after cooling: Once cool, plug in and run a short test. If E14 returns quickly, internal components may be overheating.
Service: A technician should check the internal thermal cut-outs, cooling fan, and transformer temperature and replace any failed parts.
