Re: My Whirpool dryer model LXE 7400 WO doesn't
Unplug the dryer.
Remove the back panel.
Inspect the wires at the terminal block where the cord connects.
With a volt meter set for continuity check the thermal fuse on the heater canister(up high). No continuity , replace it.
Check the hi limit thermostat at the heater terminals, no continuity , replace it.
Check the heater terminals for continuity. If none replace the heater.
Remember to remove at least one wire from each part before testing.

Ain't no moisture sensor. This is is not an electronic sensing machine. It uses another method to determine dryness. An orange wire connects to the base of the heating element. The timer motor is driven by power from it in auto dry. The timer motor is VERY slow. Slower than most dryer timer motors.As the clothes get dryer the heat is not needed so the element is turned off by the control thermostat which is mounted next to the skinny white fuse on the blower housing. This allows for the turtle like motor on the timer to advance. Once the clothes get to the point of dryness the heater stays off way longer and the timer motor advances on over to the cool down and carry on over to the end of cycle. So the clothes won't always be dry due to factors like lint buildup in the blower housing, venting to outside and so forth. having said that my mom bought a brand new Kenmore dryer and I set it on 55 minutes timed drying. At the end of that them clothes is still damp. I then set it to auto dry high heat and that usually gets em dry. I think the main probo with this dryer is the thermostat ain't set as high as older models to keep the heat at a moderate temp so that the limits won't blow on models in apts and such. Just a theory.
You will first need to determine where the problem is, I would disconnect the dryer vent from the dryer. Now if the drying improves, problem is not the dryer, its the vent system. If no change, does the unit heat at first then slowly fail to heat? Does it produce any heat? I need more information to direct you in the correct direction.
Please get back to me
Your Sensor that senses the clothes are wet or dry is shorted out. The dryer works likes this so the dryer heaters dont stay on while the clothes are dry. When the sensor senses the clothes are damp or wet, the heater stays on, when they start drying the sensor senses it and starts to turn down the heaters
When the dryer wont heat up and dry clothes it means that the thermostat/thermal fuse is bad and needs replacement. This part is located on the blower wheel housing inside the duct, please get back to me if you have any other questions.
You are correct. Pull the dryer out and disconnect your venting from the back of the dryer. Turn your dryer on and check to make sure your dryer is blowing air out of the dryer duct. If it is then leave your dryer out at least 2 ft from the wall and run a load of clothes through the dryer. If it dries your clothes normally then you have a venting restriction. Check to make sure your venting is clean, not kinked or smashed, make sure your outside vent is opening an doesn.t have something blocking it. Check your lint screen filter by running water through it. If water is not flowing through it, you have a build up of fabric softener on your screen, blocking air flow. Scrub your screen off and test again. Good Luck, Appliance Specialists
Sounds like the problem is the solenoid coils on your gas valve. easy to replace and inexpensive + common. their are 2 coils on the valve that have 2 wires each going to them. Let me know if you have any other questions,
