By "not good", do you mean a bad motor? Even if this turns out to be a motor, it's still cheaper than replacing a dryer! ($100 for part #303358)
It would not hurt to have your husband remove the back plate where the power cord is connected and look to see that none of the wires there are burned. Sometimes a loose connection can cause similar symptoms to the one you describe, but if it appears OK, the motor is bad.
There are manuals available
for the older dryers to help with the repair, and repair it you should, since Maytag ain't making the same quality stuff as this one any more!
