Samsung Microwave Error Code E-05

E-05 indicates that the cooking time entered for combination mode exceeds the maximum allowed limit of 45 minutes. Combination mode is the setting that runs two cooking functions simultaneously, such as microwave and convection. The control board rejects any time input beyond 45 minutes and displays this code. Press Cancel to clear it, then re-enter a time of 45 minutes or less.

No, E-05 is not a safety-related error. It is a user-input validation alert that prevents the microwave from running a combination cycle beyond its programmed time limit. The appliance is not damaged and poses no hazard when this code appears.

In most cases, E-05 requires no repair and therefore no cost, since it is resolved by re-entering a valid cook time. If the error is being caused by a faulty membrane keypad or control board, keypad replacements typically range from $20 to $60 in parts, while a control board can range from $80 to $200 or more depending on the model. Professional labor will add to those estimates.

Press the Cancel or Stop button to clear the error and reset the control panel. Then re-enter your combination mode cooking time, making sure it does not exceed 45 minutes. If the error clears and the microwave operates normally, no further action is needed.

Yes, pressing the Cancel button will clear the E-05 error in most cases. You can also unplug the microwave for about 60 seconds to perform a full power reset. After clearing the error, simply re-enter a valid combination mode time of 45 minutes or less.
