Is it beeping?

It sounds like you are referring to the drum baffles when you say "beater bar". If that is so, you need to remove the front panel then raise the top cover to access the baffles mounting screws outside the drum. Below is the link to the procedure I posted previously.

Maytag Neptune Dryer Front Panel and Top Cover Removal

first take the door out from the hinges then the frame around the door the you can open the top or the front of your machine...

Remove the top and front of the machine. (Look for up to two screws them pop the top.) Remove the drum (be careful of the belt) Reattach the paddle - it should be self evident once you have the drum out. You might need to add a screw of two. While it is apart, Id be changing the belt.

Reassemble

Simple.

remove door screws and screws on opposite side. pull front forward and down. remove two brackets at top corners to raise top (unplug machine of course). screws are on outside of drum.

I had a similar problem, My washer spun but the clothes were still soaked with water. We replaced the inertia switch. That solved it.

Take the four screws, out of the door and remove it. The front of the dryer will fold down and lift off, you will be able to see in side the dryer. If you want to lift the top remove the screws that are now exposed. Along with the brackets the top will now lift up.

This should allow you to access the tumbler.

I'm trying to remove the top cover in order to relace one of the fins inside the drum. The screws came loose and let go. I'm struggling to get the top off. Which screws in the from need removed to release the front? Thanks.
