my dryer will not start, I can feel the heat in the drum, I have a code F31, the code sheet that came with the dryer only goes to F30,,, what does the F31 mean

I am doing a bit of guessing here but F30 is a air flow problem so odds are that F31 is also related to air flow.

It sounds like you have the tech sheet so you may want to look at the stored error codes.

You should not have heat if the drum is not turning.
There is a centrifugal switch (on the motor), it closes when the motor gets close to operating speed. This ensures that the heater does not come on until there is air flow.
So if you have heat with the motor off the most common cause is a grounded element, see below.

Check the heating coil.
Unplug the unit and both wires to the coil.
Check it with a meter, should be around 10 ohms.
Then check from each side of the coil to the case/frame, both should be infinite ohms (open). If not the coil may have sagged or broken and is touching the case. This can cause it to heat with the motor off giving you an error..

If the motor is on, then
Unplug the unit and disconnect it from the vent system.
Now try a run.
If it now dries OK odds are the vent system needs checking/cleaning.
Be sure to check that the louvers on the outside of the house open correctly.

If you do not want any lint in the house.
Take a pair of pantyhose.
Put one leg into the other and then attach this to the dryer's vent.
Leave enough room so the pantyhose can balloon out like a windsock.

Both the above will let you check the temperature and the air flow.

Note: The above is not recommended for gas dryers due to carbon monoxide concerns.

I found the fuse in the back blew, what caused I don't know,,, I checked for airflow, it was good and clean,, the dryer works ok now however common sense asks me what blew the fuse in the first place,, I gave 1700.00 for the dryer and washer they are but 3 years old so I baby them,, running the codes again I still have the 31 code???

My response is still the same.
If an element is grounded it cannot be controlled so can cause the thermal fuse to blow.
