What Flashing ":" or PF in display means

On JennAir over-the-range microwave hoods such as the JMV9196CS, a flashing colon or PF in the display means there has been a power failure or the clock time has been turned off. When power first reaches the microwave, a colon blinks. It is a status message rather than a defect. Touch Cancel/Off, or Cancel, depending on the model, to stop the blinking.

Common causes of Flashing ":" or PF in display

  • Power outage or brief interruption
  • Breaker switched off and on
  • Clock display turned off in the settings
✓ One safe check you can try

1. Touch Cancel/Off or Cancel to stop the blinking. 2. Reset the clock to the correct time. 3. If you had a power outage, wait for power to return before running a cycle. 4. If the colon blinks again without any outage, call us.

! Why to stop there
  • Repeated power losses can mean a loose connection.
  • If the display resets by itself, the control may need a check.
  • We quote in writing.
Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

Flashing ":" or PF in displayFlashing ":" or PF in display questions
Does the blinking colon mean something is wrong?

Not usually. It means power was lost or the clock is off. Touch Cancel and set the time, and the display returns to normal. It needs no repair.

What does PF stand for?

It indicates a power failure. The microwave lost power briefly and is asking you to reset the clock. Touch Cancel and set the time again.

When is this worth a repair call?

If it happens repeatedly with no outage, something in the power supply or control may be intermittent. We can then check the cord, the connection, and the control without guessing.
