Samsung Microwave Error Code E-02

E-02 on a Samsung microwave means the cooking time you entered is longer than the maximum allowed for standard microwave (MWO) mode. The control board detects the over-limit input and blocks the cook cycle from starting. This is a user input error, not a hardware failure. Pressing Cancel clears the code so you can re-enter a valid time.

No, E-02 is not a safety-related fault. It is an input validation error that prevents the microwave from running an excessively long cook cycle. The unit simply refuses to start until a valid time is entered. No components are overheating or failing when this code appears.

Pressing Cancel resets the input and clears E-02 immediately in normal circumstances. The error will not return as long as the cook time entered stays within the model's maximum limit. If the code keeps coming back without unusually long times being entered, a sticking key or faulty control panel may be the underlying cause and should be inspected.

In most cases, yes. Pressing the Cancel or Stop button clears the E-02 error and returns the microwave to standby. You can then re-enter a cook time within the allowable maximum for your model. If Cancel does not clear the code, try unplugging the unit for 60 seconds and then powering it back on.

If the error is caused by a user input mistake, there is no repair cost at all since pressing Cancel and re-entering the correct time resolves it. If a faulty membrane keypad or control panel is causing phantom inputs that trigger E-02, replacement parts and labor can range from roughly $50 to $200 or more depending on the model and whether a technician is needed.
