Symptoms
- Repeated beeping continues after a cook cycle ends
- Opening the door usually stops it
- May also happen with no apparent cycle running
- Display may show 'End' or a similar completion message
Likely causes
- CommonNormal end-of-cycle reminder beepingMany microwaves beep repeatedly until the door is opened or a button is pressed to acknowledge completion.
- PossibleStuck start or other buttonA physically stuck button can trigger repeated or continuous beeping.
- Less commonControl board glitchRarely, a glitch causes beeping outside of normal cycle behavior.
What to do
- Open the door briefly or press the button typically used to cancel/clear, which stops the reminder beeping on most models.
- Check your manual to see if there's a setting to reduce or disable the end-of-cycle reminder beep count, which some models allow.
- If beeping happens without a cycle running, check whether a specific button feels stuck compared to the others.
- Unplug the microwave for a minute to reset the control board if beeping seems unrelated to normal cycle completion.
- Test after the reset to see if the beeping was cleared.
- If beeping continues abnormally after a reset and isn't explained by a stuck button, have a technician check the control board.
When to call a pro
If beeping isn't explained by normal cycle-end behavior or a stuck button, an appliance technician can check the control board.
