What causes Frigidaire Microwave SE?

A shorted membrane keypad (touchpad), the cause Frigidaire's support team names for SE. A key that is physically stuck or held down, for example by grease, a sticky spill, or something leaning on the panel. Moisture or steam getting into the keypad, common on over-the-range models above a busy cooktop or after a cleaner is sprayed on the panel. A loose or poorly seated keypad ribbon cable at the control board, which one iFixit owner found caused an intermittent SE. A failed electronic control board, a less common cause technicians name when a new keypad doesn't clear the code. A temporary control glitch after a power surge, which a breaker reset clears.

How do I fix Frigidaire Microwave SE?

Turn off the microwave's circuit breaker or unplug it, wait about ten minutes, then restore power. This is Frigidaire's first step and clears many false codes. Look at the keypad for anything pressing on it or a sticky spot around one key. Wipe the panel with a soft cloth lightly dampened with mild soapy water, then dry it. Don't spray cleaner directly onto the keypad. If you suspect steam or water got into the panel (for example after heavy boiling on the cooktop below), leave the microwave unplugged or the breaker off overnight with the door open so it can dry, then try again. If SE comes right back with nobody touching the panel, stop and plan on a keypad or control panel replacement. Write down the full model and serial number from the label inside the door frame so the right part is ordered. Leave the control panel removal and ribbon cable checks to a technician, or to someone who knows how to work safely around a microwave's high-voltage parts, as Frigidaire recommends.

When should I call a pro for Frigidaire Microwave SE?

SE returns after a ten-minute power reset: book service. Frigidaire's customer line in its current microwave use and care guide is 1-800-374-4432 (Canada 1-800-265-8352). The microwave starts, stops, or beeps on its own: keep it switched off at the breaker until a technician has checked the keypad and control board. A new keypad didn't clear SE: have a technician check the ribbon connection and the electronic control board before buying more parts.

Frigidaire Microwave SE Error Code: Shorted or Stuck Keypad (What to Do)

Q: What does Frigidaire Microwave SE mean?

SE on a Frigidaire microwave means the control thinks a key on the touch keypad is being held down, which almost always means the membrane keypad has shorted or a key is stuck. Frigidaire's support team says to turn the breaker off (or unplug the microwave) for about ten minutes and try again. If SE comes back, the keypad (often sold as part of the control panel assembly) needs replacing, and Frigidaire recommends a technician do it. On some displays SE looks like 5E; it is the same code. Frigidaire's official support team, answering owners on Fixya, has described SE in the same terms several times: the code relates to a shorted keypad, or in another answer, the keypad is stuck. Because the control reads a shorted key exactly as if someone were pressing it nonstop, the microwave may beep repeatedly, ignore other buttons, or refuse to start. Frigidaire's first step is a power reset: switch off the household circuit breaker or unplug the microwave, wait about ten minutes, then restore power, which clears many false error codes. If the code doesn't clear, Frigidaire says the keypad would need to be replaced and that this isn't a simple DIY job. One owner asked about a 5E code, and Frigidaire's answer was that the code is SE, so if your display seems to read 5E, it's this same fault. Technicians on Fixya and iFixit add two more possibilities behind the same code: a loose or poorly seated ribbon cable from the keypad to the control board, and less often a failed electronic control board.
