When you press the Popcorn button and then Start on the Salton MW-2047 microwave, the 2 beeps you hear are normal audible confirmation signals from the microwave. They simply indicate that the device has successfully registered your command and that the popcorn function has been activated.
This is completely normal behavior and does not indicate a problem. These confirmation beeps are designed to assure you that your action has been acknowledged before cooking begins.
If cooking starts normally after the 2 beeps: everything is functioning correctly; it’s just the device confirming the start of the program.
If the microwave does not start after the beeps: check that the door is properly closed, as the microwave cannot cook if the door is not completely latched.
