What does F24 error code indicate?
If the troubleshooting tips regarding water fill in the above previous answer do not help you resolve this problem, then it is likely that you will need to check the wiring connections between the temperature sensor and the control board. To access the temperature sensor at the back of the tub, you will need to
unplug the washer
and remove the back panel. You can view the location of the temperature sensor (also called negative thermistor control) on the parts list diagram at the Sears PartsDirect website
. This sensor is Key 24 on the TUB AND BASKET PARTS subcomponent page. To access the control board (with the washer still unplugged), you will need to remove the top washer panel. Screws at the very back of the top panel secure it to the washer cabinet. Remove these screws and pull the top panel backward slightly and then up and off of the washer. If the wiring connections are okay, then you can test the resistance of the temperature sensor as indicated the previous answer provided above. If the resistance is significantly out of range, then the sensor will need to be replaced. NOTE: You should only access these internal components if you are completely confident in your technical ability to safely complete the procedures. Internal metal edges in the washer can be sharp. Protective gloves are recommended.
This technical information should help you diagnose and repair the cause of your F24 fault code. If you need more help, resubmit your question with additional details.
