Hi bbryant981...

Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor/thermal fuse one at a time by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor/thermal fuse as it is faulty.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,
then you do not have to tape the wires together as described above.
To test your thermostat/thermistor/thermal fuse remove the wires from the thermostat/thermistor/thermal fuse and check for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.

Dryer does not heat correctly code F31

The thermostat which is a round 2 wire control on the blower box on the back of the dryer controls the heat on all dryers. always shut off power when checking any electrical appliance. Clothes dryers are wired with 2 voltages, The 240 volt supply is for the heating element only, while the 120 volt supply gives power to the timer and motor that spins the drum and powers any lights and switches. If the heating element is coming on, try replacing the thermostat. As always unplug the dryer first.

Dryer starts, but stops in a few seconds, display code F 40

The F40 error is a communication error which means the main control W10111616 is not communicating with the motor control part number 8544799.

First - go through the machine and check all harneses 7 plugs. This expensive machine uses the cheapest parts possible. Unplug and re-plug all connections you can find.
Particularly the controller (CCU) and motor.


Most likely neither control is the problem but since the main control was replaced we know it's not the problem.

The key to diagnosing this problem is to check voltage to the motor control. There is a black and white wire going to L1 and neutral.
Refer to the wiring diagram for an image of this.
If there is 120 volts to the control and the blower motor is not running then the 8544799 motor control is most likely at fault.

It is more likely you will not read voltage there.
Use extreme caution checking live voltage and only do so if you're comfortable and confident using a volt/ohm meter.

If there is no voltage to the motor control and the main motor doesn't run the thermal fuse can be at fault or the main control which was replaced and didn't help.

From the description you give I believe the main motor is running when you get the F40 code so the thermal fuse and main control are most likely okay.

If there is no voltage to the motor control then the problem can be a fuse link that may be open preventing voltage from getting to the motor control.

This part is not the thermal fuse and is not listed in the parts diagram or even shown on the wiring diagram. The fuse link is most likely the cause of your troubles.
If the inline fuse link is open you will have to replace the entire wire harness. The inline fuse link is not available as a separate part.

Kenmore Elite Oasis Steam dryer runs but gets a F 40 code and stops. Just plugged it in to do my first load. Tried pulling out and checking lint in vent. It seemed to over heat the first time then sat a...

After just now calling the service center it seems that unplugging the machine for 30 seconds or so will reset the control panel. The F 40 code means the signal wasn't working in the machine and resetting it solved the problem. Kind of like when you have to unplug the computer sometimes.
