Fixing a couple of screw holes on a dryer
Based on the comment thread, your screws are not damaged excessively. This means you can take the good screws to a local hardware store and ask for a matching tap to clean or re-tap the threads in the door. The hardware store person should find a nut to fit the screw, identifying the thread as metric or SAE and then match the tap tool accordingly.

For a one-off task such as this, you can get away without a tap handle. Use an adjustable wrench set to match the flats on the tap, place the tap in the hole and attempt to start the cutting threads to match the probably-damaged threads in the dryer wall. Because the threads were there previously, you won't have to use the forward half-turn, backwards quarter-turn practice used for tapping a drilled hole. A bit of lubricant would be useful, a light oil or even motor oil.  The image below is an arbitrary selection from Amazon.



Once the tap spins with minimal effort, back it out and your screws will fit again.
