Samsung Microwave Error Code E-24 — Over Temperature Error
What this means
The E-24 error code indicates the temperature inside the microwave has exceeded the maximum safe operating temperature. The microwave automatically shuts down to prevent damage to internal components and reduce fire risk. This typically occurs in convection models during extended high-temperature cooking, or can be caused by a faulty temperature sensor, a malfunctioning convection thermostat, or blocked ventilation.
Alternate codes: E24
Step-by-step fix
3 stepsLet the microwave cool completely
Turn off the microwave and let it cool for at least 30 minutes before attempting to use it again.
Do not open the door repeatedly — let the internal temperature come down gradually.
Check ventilation
Ensure the microwave's ventilation openings are not blocked. Over-the-range models need clear vent paths. Countertop models need space on all sides.
Check that the exhaust fan is operating (on over-the-range models).
Reset and test
Unplug the microwave for 60 seconds after it has cooled. Plug it back in and try a short, moderate cooking cycle.
If the error occurs again quickly, the temperature sensor or thermostat is likely faulty.
When to call a professional
Overtemperature errors that recur require professional diagnosis of the temperature sensor, thermostat, and control board. Do not continue using the microwave if it repeatedly overheats.
