Why does my microwave says PF?

If a power failure should occur, a microwave, depending on the model, may display a “PF”, “888” or “8888” code. It is possible to see this display upon initial installation or after power was restored due to a power failure. Both display codes can be cancelled and normal operation resumed by touching the CLEAR pad.Click to see full answer. Hereof, how do I reset my microwave? Power surges like nearby lightening can cause the oven to stop working as a safety measure, but you can reset it easily. Press the “Off/Clear’ button to cancel anything on the display, and reset the microwave. Press the “Off/Clear’ button for three seconds to turn the “Control Locked” child lock off. One may also ask, why is my microwave shutting off? If the microwave runs for a few seconds and then shuts off, the door switch might be defective or loose. Sometimes arching or overheating of door switches stops microwave from running efficiently. Some microwaves have a seal or gasket around the door. If the seal or gasket is broken, microwave shuts down. Additionally, what does it mean when a microwave says f3? The F3 means you have a shorting membrane keypad.
