Whirlpool F3

Oven/Range/Cooktop Repair
,

My Whirlpool oven often displays F3, beeps loudly and turns off. Sometimes it will shut down without the F3 and beeping. Checking the error codes on the internet led me to believe I needed a new oven sensor. I replaced the oven sensor and still have the same problem.

Here are your parts

See the attachment for the tech sheet.

I would check the oven sensor with a mter, just to ensure you do not have a defective sensor.

If OK.
Disconnect it from the clock (control board) and check it from that end, to make sure you do not have a bad wiring harness,
If OK
Check that the connector on the clock is clean.
Remove the clock and check for a bad connection or cold solder joint on the board.
Cold solder joints are often a duller gray and/or have pinholes.
Also wiggle the components to see if the the component legs on the solder side of the board move.

If all OK then your clock is toast, unfortunately it looks to be obsolete.
There are companies that fix boards, Google " appliance timer repair".

If you do not own a meter, I would suggest you purchase a one. You can get a decent digital multimeter for under $20.00. You do not need fancy though it is nice if the leads are a couple feet long.
If it saves ordering one unnecessary part it has paid for itself and you end up owning a useful tool.
Most places will not let you return electrical parts so if you order it, you own it.
A couple things to watch when measuring ohms and continuity

  1. Always remove power from the machine otherwise you could blow your meter.
  2. Always disconnect at least one side of any device you are checking. This eliminates the possibility of measuring an alternate/parallel circuit path.
  3. When checking for closed contacts and continuity use the lowest scale (Usually 200 ohms). Then try higher scales. This scale is 0 to 200 ohms so if the device you are measuring is 300 ohms this scale would show an open circuit which it is not, you are just measuring outside the scale’s dynamic range.

There is a good STICKY at the start of this forum about it’s use.
