FIn inside neptune md55 dryer came loose need to remove side pane
I had the same problem but it's the FRONT Panel you need to remove. Before you start, unplug the thing first. BTW I did the whole proceedure in 10 minutes using an electric screwdiver / philips bit and a socket set with an 8mm socket with my leg in a cast. You can do better, I'm confident!
Two 8mm hex head bolts hold each fin on the drum. They can be tightened. You need to open the dryer front since they bolt from the outside of the drum. To open the dryer front you first take the door off by removing the two philips head screws, then slightly lift the door and pull toward you (the door hinges have little hooks on the end that inserts into the slots (this little design keeps the door from falling off during removal and install-nice). Then remove the two philips screws on the other side of the door opening (opposite the door hinges). These screws hold two plastic brackets (be sure to see how they are aligned before you remove them so you know how they go back on.
Now the front frame panel looks like an "H" . Grab the top two arms of the 'H" and give a quick ****. The top arms of the 'H" will come loose. The bottom part is held by a couple of clips, just pull up and the front panel comes off.
You will be able to spin the drum until the hex bolts for the fin(s) in question are visable / reachable from the right side (just above the heater unit-hope you unplugged the dryer earlier). I tightened it using an 8 mm socket.
Now reverse your steps: put the front panel back on the bottom clips and snap the top "H" arms back in place. Reinstall the plastic clips / screws and then put the door back on.
