Maytag Atlantis Dryer (Mod: MDG7400AWW)

[lep]

Was getting no heat during run-time, so disassembled dryer to perform ohms tests with one wire unhooked. Results:

Heating element: thermostat-->passed
Heating element: fuse-->passed
Heating element: ground check-->passed
Blower housing: fuse-->passed
Door frame: Moisture Sensor Bar-->Failed

With the dryer disassembled, and electrical power and gas turned on and when depressing the open-door limit switch, pulling out the start button (intellisense, and timed heat as well as gentle, normal temp), there is no flame.

Question is: would a failed moisture sensor bar prevent needed feedback to the system that's required to ignite a flame?

If you are not getting heat during run-time it is very possible the sensor is bad. But before you swap it out, I would try cleaning the bars at the door frame with a brillo pad and test the sensor again. Sometimes dryer sheet lint and crud can cause the moisture in the clothes that are in the drum not to be detected by the sensor.
