This is valid for a Maytag Neptune MDG3000AWW Gas Dryer (I am responding to a problem which was mis-identified as a MDG5500AW Gas Dryer)
NOTE: Motor problems begin intermittantly. They can be temporarilly fixed by blowing out the motor with compressed air. Eventually ALL motors fail. In my case, with six kids it took 10 years for our Maytag motor to fail. YMMV.
Confirm where the burn smell is coming from. This will require you to disassemble the dryer. This is not hard - it will require the following tools:
crosstip medium screwdriver 1/4 inch socket 5/15 inch socket
TURN OFF GAS
Disassemble by taking apart the FRONT of the dryer:
a. Remove the door and opposite side door plugs (crosstip screws)
b. Remove the front panel - this exposes sheet metal bolts (5/16 inch) some with crosstip on left and right of unit. Set panel aside (right side) WITHOUT unplugging wires
c. Unscrew all the exposed bolts.
d. Top bolts left and right secure the unpainted metal hooks which secures the top of dryer. Unscrew these bolts and wiggle the metal retainer hooks off. Lift top and support to create 6 inch gap in the front (top unit hinges in back and has electrical connections - do NOT disconnect wires)
e. Release belt from pulley by reaching left and under drum (this is out of sight)
f. gently lift out drum and belt and set aside
This has exposed the interior.
IF your motor still made sounds when pressing the start button, THEN plug the dryer back in and have an assistant press and hold the start button. You press the dryer close door button (on front panel which you set aside) and observe and listen. IF the glow plug in the gas ignition chamber glows bright, it is fine. You may see a slight curl of smoke or smell some smoke from the glow plug. THIS IS NORMAL and indicates your ignition circuit is fine.
Observe the motor. Listen and smell. IF you see smoke from the motor, or IF you hear a "starting sound" but the motor itself doesn't spin, is very slow to start spinning, or makes racket, or it made a noise and then stopped... THEN your motor is burned out. Confirm by sniffing the motor. IF the motor smells burned, THEN your motor is burned out.
IF you determined your motor has burned out, THEN you can replace the motor for around $100. OR you can replace your dryer for > $700. Your choice. It is slightly tricky getting the motor out. Instructions Below.
NOTE: If your motor is burned out it CANNOT be fixed because it is a "double wound motor." The motor must be replaced.
MOTOR REMOVAL INSTRUCTIONS
TURN OFF GAS
Expose the dryer interior by following instructions above
With the drum out do the following:
Remove the blower cover by unscrewing the 8 screws
Remove the cotter clip securing the front of the blower to the motor spindle (Try using two screwdrivers... You'll need to replace this cotter clip because it will deform)
Remove the wiring harness on the back of the motor
Remove the two motor securing clips holding the motor to the motor support frame (this is tricky - I got them off by leaning on the top of the clip with a heavy screwdriver and a large channel-loc wrench)
Remove the cotter clip between the motor and the blower housing
Remove the two 5/16 inch bolts securing the motor support frame from the motor
Lift out the motor and blower housing
Have an assistant support the plastic blower barrel tines with the motor hanging down and the blower up
Using a hammer and a punch tap the motor spindle (axel) until the blower is free of the motor
Take this motor to your appliance repair center for replacement.
To replace simply reverse these instructions. GOOD LUCK!
Its possible the start button or the door switch is trying to go out, try bypassing the door switch and start it, if that doesn't help try bypassing the start button but be careful theres 115 volts there! Use a jumper wire to start it.

Re: maytag gas dryer
The most likely cause for this situation is the ignitor for this unit is known to burn out, it is an element that uses 115 vac to glow red hot and ignite the gas it is very easy to change and are normally cheap.

I had the same problem. Here's a quick test you need to do. It will take two individuals (unless you're extremely talented) Open the dryer door and push in the door switch... and hold it in. Have the other person push on (and hold) the start button on the console. At that same time everyone is pushing the switches take a free hand and reach into the dryer and try to spin it. Sometimes just a little push (assistance) is all it takes and..... bingo the dryer starts up! If that's the case... your motor is on its way out or it's gone. Usually due to the bearings on the motor being badly worn.
