    You must have either a bad door switch, a bad motor or a bad timer IF you have power going to the unit. these are what I would check next. I made a video of a roper dryer repair. Even though they do not look the same, all dryers work the same. It will give an idea what to look for:

It is dangerous to do but you have to turn dryer on while it is apart and wait for limit to open up, then test. !st make sure all connections are ok. The clips and the nuts all need to be tight. If any look dark or burnt that may be your weak link. If you are sure that everything is else is working ok, a set of high limit switches is not very expensive. The voltage is 220 so if your careful you can test at each junction, but be careful..

MDE5500AYW Maytag Neptune not heating. Heating Element, both high limit thermostats and thermal fuse have been replaced. What could be the problem?

Firstly, you have not mentioned that you have verified the presence of a power source of 240 volts, so make certain of that issue. If you have proper voltage, then the motor centrifugal switch could be at fault
Below is a link for trouble shooting your model.

Neptune dryer proble. The dryer works except no heat. Flame starts, but then turns off. Igniter element was checked and is good. What else should I check in order of probability? - flame sensor? -...


Thanks for using FixYa. Things that could stop an 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.

Please do accept the solution if the issue is resolved or else revert for further assistance.

Heats upon start-up then heat shuts off

This could be caused by a partially burnt heating element or a faulty high limit thermostat. The more likely cause ( I think) would be the high limit thermostat. It is a small round black device mounted on a metal plate. It is usually attached to the internal ductwork with two screws. You can test it with a multimeter for continuity. It should have none. If it has continuity, then it is stuck open and is defective. Hope this helped and best wishes.

Neptune mdg3000aww starts heating and runs fine but stops heating shortly after start up can restart heater starts again and shuts down

If the machine keeps running but just not heating you have a thermostat issue. It could be the operating therm. or the high temp limit therm malfunctioning, shutting off the element.

If the machine stops running completely, check the door switch.

Maytag elec. neptune dryer won't heat

The first thing I would check would be your high limit thermostat. It is located near the heater and is wired in series with the heater. The contacts in a high limit thermostat remain closed at temperatures below 250 degrees. The contacts will open and interrupt the circuit to the heater when the operating thermostat, thermistor or electronic control fails to cycle properly. The most common condition that causes the high limit thermostat to operate are vent restrictions, blower failure or a defective operating thermostat or thermistor.
If those are good, then,

Check your dryer heater. With both heater power terminals disconnected you can check for resistance. The typical dryer heater resistance is around 20 Ohms.
If you can not read resistance on the dryer heater then it is an open circuit and needs replaced. Also if your meter indicated an electrical path between either of the heater terminals to the heater frame (ground) then it’s bad. The heater must be isolated from its mounting frame.

Slow to dry cloths

Remove the vent from the back of the dryer and see what the temps are. The cycling (or operating) thermostat is on the blower housing and opens more than 100* lower than the 266 you are reading. That, combined with the long dry times indicates an airflow issue. Check your lint screen....fabric sheet and lint can combine to coat and restrict air flow through it. Also check down in the blower housing with the lint screen removed. You'll see lint build up by looking down the slot with a flashlight. If it's restricted, so is the blower wheel and the blower housing. Also make sure the flap, or lovers at the vent hood outside are opening fully. Remove any accumilation of lint from there.

The high limit control is just that........If you cycling thermostat has failed, or does not open because there is no airflow, the limit control opens as a safety. On a normally operating dryer, the high limit control will never open.

The neptune dryer is designed to move more air than a regular dryer due to the higher capacity load it get's from the neptune washer. That is the case with most front load laundry pairs.
