Question about Maytag Atlantis MDE7400AY Electric Dryer
My dryer (~6 years old) runs, tumbles clothes, but does not heat. It worked fine until yesterday when I cleaned the vent. When I put it back in place it did not heat.
PSUinNC The first thing you have to do is to check in what position is the temperature switch . If the temperature switch is in the "air fluff" position, then the heater will stay "off". If this is not an issue, reset the circuit breaker. The motor needs only 120V to run, but the heater needs 240V and if one of legs is missing, the dryer would not heat. If it did not solve the problem, you have to perform full diagnosis. You will need some simple hand tools and a meter to check a continuity. If you are fillng you can handle it, let me know and I'll give you the step by step instructions. Gendos...post back

Image sample may not be identical but will be close
The most common cause for no heat is a blown thermal fuse. If you cleaned a lot of lint out there may have been sufficient air restriction to overheat and pop the fuse. It is not resettable, but in NS costs around $8.00.
Remove the plug from the socket
remove the rear cover
trace the exhaust air lines untill you find something that looks like the image above, its about the diameter of a quarter. There are often 2
remove the two wires,
test- with a multimeter 0 resisttance=good infinity resistance = bad
- with a battery and bulb, lights = good, dark = bad
If fails test, unscrew two retaining screws, take the thermal fuse to your local dealer and buy one of the same type,
Dealer will have them there are only about 5 kinds for every dryer made.
screw in, reinstall wires, reinstall back, plug in, Dry

The Igniter is the most replaced part for "no heat" followed by vent blocked 2nd. Thermal fuse / Split coils dead heat for 3rd.Thats a So.Cal. Trifecta.

i am sending you all the possibilities for your problem, check either of these causes ----and than let me know if it is solved----
Power from the house
Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.
Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.
On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.
