It's an older Maytag and I just replaced a broken belt when this problem appeared. The dryer starts making noise as it heats up. It will run on cool cycle forever. Help

Motor malfunctions usually call for service by a professional. There are three main causes of motor failure: lack of lubrication, a defective motor switch, or worn or frozen bearings. A humming sound can be related to a burned-out motor or a defective switch. Check these trouble spots before you call a professional service person or take the motor to a repair shop. Here's how to check a dryer motor:
Step 1: Remove the back access panel. Then reach behind the drum, motor pulley, and idler arm pulley. If these areas are clogged with dirt and lint, undue strain on the motor may be causing the humming noise. Worn or broken belts can also cause a humming noise. Check the belts for wear and damage. If the belts look all right, you may be able to stop the noise by spraying them with fan belt dressing, available at automotive and hardware stores and home centers.
Step 2: Turn the dryer on. The noise you hear may be the whirl of the spinning drum, not the motor. Some noise is normal.
Step 3: Force a little 20-weight nondetergent motor oil (not all-purpose oil) around the ends of the motor shaft. This lubrication may stop the humming noise. If this doesn't solve the problem, remove the motor and take it to a professional service person.The centrifugal switch on the dryer motor may be located on top of the motor. Humming, no motor power, and no heat can be caused by a faulty centrifugal switch. If the switch is externally mounted, check the terminals of the switch to make sure they are tight and not burned. If you spot trouble, remove the switch and take it to a professional service person for testing. A faulty switch will probably have to be replaced. Some centrifugal switches are located inside the motor housing; you won't be able to remove the switch in this case. Remove the entire motor and take it to a professional for repairs.
If the motor hums, but won't run the pulley on the end of the motor shaft, try turning the pulley by hand.Caution: Before turning the pulley, make sure the power to the dryer is turned off.

the humming noise is most likely your motor. does it overheat or shut down on you? do you smell anykind of burning? Joe

I had a similar problem years back. It was the ignitor. The ignitor is a ceramic like piece that heats up (glows red) that ignites the gas. Typically when that goes, you will see some white residue build up where it cracked, thus breaking the electrical connection. This thing works like a heating element on an electric stove, but rougher looking.
The part was about $30 at my local parts store. I bought an extra one just in case so I have it on hand. I installed it with common tools.
You can check it to see if you lost connection by using a volt meter.
Good luck.

UNPLUG the dryer. This model you need to remove the two screws under the lint screen. Now use a flat blade screw drive and insert it in the gap between the top and the front panel and pry the top up. Now locate and remove the screws on the inside of the front panel in upper corners. The front should lift off. You will see the two black coils on the gas valve. When you remove the three wire coil, make sure the sleeve inside it gets put back on the post the coils slides onto.
If I can assist you further, please let me know.
Thanks
