I was trying to replace the drive belt on my dryer but while opening the top by removing the screws from the lint trap opening I accidentally dropped the pocket knife i was using down the lint trap and now it takes a long time to dry things and I'm afraid of what will happen if I dont get the knife out some how. How should I go about getting it out?

Unplug
use a scrapper/puddy knife just under top find clips and push in on clips at same time pulling up on the top

Always unplug the dryer before working on it and watch for sharp corners.

There should be two spring clips between the top and front panels.

Insert a flat object like a putty knife about 6 inches from each side. Push in and top should raise. Once both are done top will hinge back.
The front panel should have two screws, either at the bottom front or inside top. Remove. The inner bulkhead will have four screws. Remove top two and feed belt through the face, then replace the top screws. then remove the lower screws, feeding the belt the rest of the way through. Doing it this way keeps the drum from falling. Complete belt installation. The belt goes completely around the drum , turning the around the motor with the idler arm to keep tension on it.

Unplug, remove the screws at lint trap, do not drop in trap! Press in on the clips at the front edge approximately and inch in from each side, lift top. Remove the screws on the inside of front pane;, unplug door switch, tilt front forward and lift the front off. The idler pulley (what you are calling tensioner ) slips in the slots in front of the motor. This link has a picture of how the belt is installed I wrote this article a while ago How Replace The Belt on Your Whirlpool Dryer

The pen has fallen into the blower housing and is hitting the fan blades.

Unplug the dryer!! Remove the two screws at the top of the lint trap. Remove the rear panel. Remove the four screws at the bottom that attach the lint filter housing to the blower housing. Then, remove the pen from the blower housing.

Unplug the dryer.
Remove the lint filter.
Remove the 2 screws at the lint filter opening.
Use a putty knife between the top lid and the front panel to release the clips.
They are about 2 inches in from right and left sides where the top meets the front panel.
Lift the lid towards the rear of the dryer.
Look inside the top right and left corners of the front panel and remove the screws holding the front to the cabinet. Remove the door switch wires and set the door aside.
Place the new belt over the drum,ribbed side towards the drum.
Look under the drum for the belt tensioner. It is S shaped with a wheel on it.
Place the base of the tensioner in the slots below the motor pulley.
Feed the right side of the belt through the opening under the wheel with the smooth side of the belt touching the wheel.
Place this side of the belt over the motor pulley with the ribbed side touching the pulley.
Replace the front panel.
Hook up the door switch wires.
Replace the panel screws.
Reattach the top lid and lint filter screws. Replace the lint filter.
Plug in the dryer.

its not too hard to get out.
you will need a #2 phillips screwdriver and or a 1/4" socket driver
remove lint trap
remove 2 screws at lint trap
unplug unilt
open the top (2 clips between lid and front panel in the crack, push them with a butter knife or putty knife to release top) opens like a hood
pull out dryer and pull off rear panel
on the left hand side there is a metal duct like thing lol
that leads to the lint trap at the top.
there should be 4 screws at the bottom where it gets round.
remove them, and wiggle the duct open. your pen should be there..

if it is a top mount lint filter remove the 2 screws,then take the back off,remove the screws from the blower box,it is to your left,remove your pencil and your done-mike

2 screws at bottom front, pull out slowly from bottom first. Remove the door switch wiring. Then you will see the rest. Note how the belt rides thru the pulley and onto the motor. Belt # 341241, available for $11.99 at timerking.com. Hope this helps!

Ordered drum from Sears parts. 3045EL1002D
Cost of 85$ + 15 to ship. It came in 5 days.

Here is how to do it on a DLE2514W. Takes about an hour. I only used a phillips screw

driver. Take your time and look over the situation. I hope that I rememberd

everything. Good luck.
