Reading the microwave display

On a microwave the code replaces the clock on the display. Unplug the unit for a minute to see if it clears, and note the code before you do. KitchenAid pairs the number with a letter group in the manual, so match the exact characters.

KitchenAid is Whirlpool Corporation's premium appliance line. Its dishwashers, ranges, microwaves and refrigerators share Whirlpool boards but use their own panel layouts and numbering in the manuals. The codes apply to model numbers such as KUDS24SEWH1, KUDS01DJSS0 and KHMS155LSS4; check the label on your unit to confirm yours.

What causes F2 E3

How to fix it

  1. Cycle the power: unplug the microwave (or switch off its breaker) for one minute, restore power and test it briefly with a cup of water.
  2. Before opening any panel, switch off the breaker or unplug the appliance; this circuit can carry line voltage.
  3. Disconnect power for the recommended time, then restart and press each key to see if one sticks.
  4. Clean the panel with a barely damp cloth and check around the keys for spills or swelling.
  5. With power off, reseat the ribbon cable or harness between the panel and the main control.
  6. Replace the user interface or touchpad if the code returns, then confirm every key responds.
  7. Run a full short cycle or function again and confirm the code stays gone before putting the appliance back into normal use.

Questions

What does F2 E3 mean on a KitchenAid microwave?

It is a fault code from the KitchenAid control. It indicates a problem with the control panel. A power reset is the first thing to try.

Can I keep using the microwave while it shows F2 E3?

You can try it after a power reset. If the code returns, the affected function may not run properly, so it is worth fixing soon before it causes a bigger failure.

Do I need a technician to clear F2 E3?

Many owners can fix it themselves. Start with the reset and the inspection steps, and only call a technician if the part tests bad and you do not want to replace it.
