Dryer indicated error codeF23 after 1 minute of operation

I followed the test guidance on the tech sheet (located behind the front lower cover). According to it, F23 was a short in the outlet thermistor. The thermistor tested good along with all the other replaceable temp related devices.
I then started a general diagnostic following the steps in the tech guide. The dryer failed a motor control step which indicated a bad control board. Replacing the board (after it arrived) took less than 5 minutes and was 100% plug and play.
The most difficult part was ensuring that the test leads for the multimeter were on the correct test points. If you are not confident in using a multimeter, I would not recommend you perform this level of repair.
