Hi, :( I have a Maytag Neptune gas dryer that will not heat all the time. I can hear the sound when the heat comes on and then about 2 minutes into the cycle it stops heating. I have cleaned the vent hose from the dryer to the outside so that is not the problem. Just want to know whether to order a thermostat or call a repair man :)

Before you oreder a thermostat, Check it for continuity first. Also open unit up and remove the bolwer housing and clean in out very good. It also cound be the coils in the gas valve. Check components before just replacing or it will cost more than the repair tech would charge

I have a Maytag Neptune GAS Dryer and it is taking a long time for clothes to dry. (long enough that I have two loads of wet clothes waiting to be dried). I checked air flow by checking the outside vent and there is plenty of barely warm air coming out. I also made sure the lint trap was clean as well. Also, I'm getting wisps of gas when I open the dryer door. It's not an overwhelming amount of gas, nor is it constant. Any ideas?

These driers will do that when the lint builds up like concrete on the inside of the air ducts. Halfway doing it will not work. You need to totally tear it down and scrape out and wash all of the parts except the motor, which you vacuum out. You can go to YouTube to see videos on how to take it apart, but do a very good job or it will fail again quickly. I would get a new belt and change it while you have it apart and get some white lithium grease and grease any bearings you find. You need to clean out a drier every two years, at least, according to the manual. You just unplug the wires from the sensors and remove ductwork that they are attached on and clean the entire thing with soap and water. Make sure you go all through the dryer and get all parts like the blower fan and housing, vacuum out motor well and clean exhaust. Mark all wires you unplug so you know where they go. This is an easier job than you would think. Make sure to clean around all of the sensors, too.
