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

Blocked cavity vents, Failed cavity temperature sensor, Open thermal cutoff on cavity, Operating with no load or improper cookware

How to Fix / Troubleshooting

Safety first: Turn off power and allow the microwave to cool for at least 30 minutes.

Basic checks:

Ensure you are always heating food or liquid, not running the microwave empty. Running empty can cause rapid overheating.
Check that the air vents inside the cavity (usually on the sides or top) are not blocked by oversized containers or covers.
Inspect the interior for heavy grease buildup; clean with a mild detergent and water, then dry thoroughly.

Reset attempt:

After cooling, restore power and test with a small cup of water on a low or medium power setting.

If E05 returns quickly:

The cavity temperature sensor or thermal cutoff may be faulty.
These components are mounted behind the cavity walls and require disassembly; contact a Wolf technician for diagnosis and replacement.
