How to replace maytag mde7400ayw intellidry sensor

could be your drying sensor .. that failed

you could have bad gas coils.if the timer doesn't advance in auto dry most likely you're having heat problems,when the dryer heats and then the heat shuts off then the timer will advance,when the heat comes back on the timer stops,it does this until the clothes are dry.gas coils when starting to fail will work normally until they get hot and then no heat until the coils cool down then they will work again,on time dry the timer just keeps counting down until the time runs out no matter what's happening to the dryer.i've seen the coils fail after the first 10 minutes and other times for 20 to 30 minutes but usually if the load is big and in time dry the clothes will feel warm and you'll need to dry them a second time to get them fully dry,also while you're in ther you should clean out the dryer at least once a year,clean out the duct that the lint filter slides into,vacuum out the cabinet where the motor is and blow out the vent line,if it's a long run i use a leaf blower to blow out the line,remove it from the back of the dryer,stick the leaf blower into the vent line and blow it out,i've blown out birds nest out of some lines, your clothes will dry on time,you won't go through so many parts and you won't have to worry about a dryer fire,the gas coils are on top of the gas valve,remove the two phillips screws,lift off the cover and change out the coils.next time you use the dryer keep an eye on it,after it runs for 20 minutws start checking it,you'll hear a click,then another click and the flame will lite,look into the gas tube and if the flame isn't liting then you have bad gas coils.

Howdy: It seems the "smart switch settings" has died. It is in the switching circuit. It all comes in one unit. Take it out and have it tested at an appliance store. Good luck - Doug

The wire connections to the timer may have not been made correctly when it was replaced bypassing the OFF contact in the control circuit.  There should be a wiring diagram inside the front or back panel that you can check.

Clean the lint filter(s) and verify unobstructed dryer exhaust. 99% of the time the dryer exhaust is clogged.

it's probably your sensor assembly. go to www.repairclinic.com/Appliance-Parts?s=t-MDE7400AY-%3d%3d&z=100 . That is the best possible solution and not too expensive. Good luck.

Most likely.  More likely the timer motor

Our Kenmore dryer had the same sort of problem (different catchy names.

Problem was that in "smart" modes (by what ever name, the timer motor runs in series with a "dampness" sensor (thermostat, actually, I think) and A RESISTOR.

Resistor burns out--this is the symptom set.

Can anyone help me? I have a Maytag Atlantis that my parents just gave me and my wife. Unfortunately, they accidently removed the model number sticker in the door area. I need to buy a new timer but no one can find which timer to get without the model number. Via the internet, I think I narrowed it down to either the MDE7400AYQ or the MDE7400AYW....but they both look identical to me. Can anyone tell me what the difference between the two is so I can go get the part?
