MED300VW1 does not pull anything up. MED
E300VW1 does. Do you see a "E' after the "D" in your model number?
If so, I'd ohm test the thermal fuse first.
You will need a
multimeter to ohm your thermal fuse. Its on your blower wheel housing. Unplug your dryer first before accessing it and ohm testing it.
Here's the thermal fuse for your model you can order here, if yours is bad:
Thermal Fuse WP3392519
This video shows how to ohm test it:
This video gives you the general idea of how to access it:
Let us know what you find.
The number 1 cause of a thermal fuse or thermal cut-off to blow out is a vent restriction either in the vent exhaust hose in the back of the dryer or outside where the vent duct vents outside.
Whenever I replace the thermal fuse or thermal cut-off I always pull the dryer out from the wall, then check that vent exhaust hose for lint clogs, and go outside the house and do the same where it vents outside.
