Question about Maytag Neptune MDE4000 Electric Dryer
The dryer turns and cycles but no heat
Q - My electric dryer runs but will not heat, what could stop my dryer from heating?
A - Things that could stop a electric dryer from heating:
- house fuse or breaker ( needs two of them ), heating element, burnt wire, thermostat(s), thermal fuse ( not all models ), motor heat switch, timer, selector switch, burnt power cord/plug.
A ohm meter test for these parts is here.

All you need to do is check the element for continuity with an ohm meter, if it has continuity the element is good. The dryer also will run on 110 volts of power but it needs 220 volts too run the element, so check and make sure all the conections on your cord are secure and that you have 220 at your wall outlet.

Gas dryers utilize a gas valve, ignitor assembly, and a series of coils mounted on the gas valve to provide heat and safety. The gas valve coils are the usual suspect when it comes to a "No Heat" complaint. I have provided a checklist from www.repairclinic.com, for your convenience. They also provide disassembnly diagrams and repair parts.
Firstly, ascertain that you have made an adequate "Heat" selection, then read on:
Warning! To avoid personal injury or even death, always disconnect your appliance from its power source--that is, unplug it or break the connection at the circuit breaker or fuse box--before you do any troubleshooting or repair work on your appliance. Also, because some components may have sharp edges, use caution while working on your appliance.
If your dryer doesn't heat, check these:
Gas valve coils
Igniter Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too.
The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one.
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.
Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing.
If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

SOURCE: dryer does not heat up.
normally on these units if the dryer was working ok and then suyddenly stopped heating your heating element or the ignitor (excitor ) has failed and is need of replacement
so i would start by having these things checked first by contacting a local repair man to do a evaluation on the unit and if kyou still have a valid warranty i would use it ok
I hope that this is very helpful for you
Best regards Richard

You really need a volt / ohm meter to check for Continuity & Volts
Its well worth the investment... $15.00 bucks give or take a few
I would check to see if you have 220v to back of dryer where the cord mounts to dryer,
If dryer is getting only 1 leg 110 volts instead of the 220 will it not heat.
Check themostates & heater for Continuity... Most models, Now have a.. Hi-limit fuses that need to be checked for Continuity
