Here are some common solutions to help resolve the issue with your appliance. Clicking on the underlined links will take you directly to that page.

If your dryer doesn't heat properly, check this: Venting restriction: Disconnect the dryer temporarily from the vent. If the flame stays on for a longer period, you may have an air flow obstruction to the outside. Gas valve coils Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time. Also, in your case, the coils may work fine initially, but heat build up can cause the coil(s) to malfunction and when they cool down will work again.

a bearing in the back for your drum sounds like what you describe. It needs to be taken apart and the bearing lubricated with high temp grease

This is usually a simple heating coil malfunction. The coil may have breaks in it causing it not to work. It could also have something to do with 1 of several heating sensors that may be broken, telling the dryer's heating coil that the dryer is too hot, in effect turning off the heating coil. If your dryer has a round lint filter in the rear of the drum, it was 1 of 2 models of Dependable care dryers produced in the 1970's. If this is the case, i supose it would be up to you whether you want to try and get it repaired or not. If you have one of the more recent models,,, the lint filter is directly behind the door, at the front of the drum. and in this case it would probably be a good idea to get it looked at it as Maytag is a relatively dependable brand.
