Recieved an he code on my amana dryer ned7200tw. No heat is present.

SOURCE: amana dryer NED7200TW quit heating, it appears

Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip.... If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat. check out this electric no heat tip...

HE shows up because there is no heat . Check the fuses in the panel and the heater itself. Also could be the sensor is not working to tell the control to turn the heater on.

Hello, welcome to FixYa.

I'll start by saying your post indicates it is a Amana dryer, (as you may or may not know this model is built by Samsung) and it is displaying a e5 error (actually looks like a e5 error, but it is indeed t5 but that's because of the digital display)...it is actually a "temperature sensor" error, hence the "ts".

As described in the service manual from Maytag...

"tS" Dryer Thermistor Short Sensed - The Thermistor resistance is very low.

Check for:

Clogged lint screen. (remove and wash under hot water & mild soap...a old toothbrush works well for scrubbing)

Restricted vent system.
Check Thermistor resistance...10000 ohms @ 77°F/25°C
If you've replaced the thermistor already, that leaves either poor air flow due to clogged lint screen or clogged exhaust somewhere else along the line. Here's what I would suggest you try. Remove the lint filter (clean it as mentioned above) and unfasten the vent from the back/side of the dryer, whatever the case on your machine. Run it through a cycle without a load and post back with the results.

I can send you the service manual if you think it may help you move forward,(It says Maytag, but those are Amana/Samsung as well) but you'd need to provide an email address for me to attach it to. It is a "pdf" and 9.9mb in size.

I'll watch for your reply.

Regards,

Macmarkus :)

Hi,

There can be many reasons why your dryer will not start or turn...

The most common causes are the belt breaking or jumping off, or the motor goingbad...

Hi abaitschmidt...

Here are a few things to check:
ALWAYS UNPLUG YOUR DRYER BEFORE ATTEMPTING TO DO ANY WORK ON IT.
Check to make sure you are getting full 220 Volt power to the dryer, if you are then:
Check your Wiring
Often the main wiring connection from the house, at the dryer, burns and the connection breaks. If this has happened to your dryer, you need to replace the power cord and the terminal block inside the dryer to which the wire is attached.
Check the Door Switch
If the door switch or the door-switch actuator is defective, the dryer won't work and you need to replace the failed component. The switch is inside the dryer main housing near the door frame. Sometimes you need to raise or open the top or front of the dryer to reach the switch. Check for continuity you should have none with door open, and should have a reading when closed. If not replace the door switch.
Check to make sure you heating problem is not a lint build up in the discharge hose or the dryer,as this condition can cause heater/thermistor problems such as overheating of the heating coil leading to failure of the coil and burnout of the thermostat/thermistor due to overheat.
Remove the back/or front just under the door of the machine and try to locate the air duct going from the blower to the drum. Normally inside/outside the air duct you will find the heating coil and the thermostats/thermistors. Once you have located the heating coil, remove the two wires from it and check the coil with an ohm meter across the two terminals of the coil.
You should read continuity across the terminals, if not you will need to replace the coil as it is faulty.
If the heating coil is ok, then:
You can check the thermostat/thermistor one at a time by removing the two wires and taping them together with electrical tape.
If the coil heats up then replace the thermostat/thermistor/thermal fuse as it is faulty.
If you have an ohm meter then you can test the thermostat/thermistor/thermal fuse,
then you do not have to tape the wires together as described above.
To test your thermostat/thermistor/thermal fuseremove the wires from the thermostat/thermistor/thermal fuse and check for continuity, if you DO NOT have continuity then replace the thermostat/thermistor/thermal fuse.
DO NOT LEAVE THE WIRES TAPED TOGETHER AFTER THE TEST AS THIS COULD CAUSE A FIRE BECAUSE YOU HAVE REMOVED THE SAFETY.
Check your blower wheel to make sure it is secure to the shaft and not plugged with lint,socks,etc.
If the thermal fuse overheats the dryer will not operate. It's located on the blower housing. It cannot be reset.
You can test it with an Ohm meter or continuity checker, remove both wires from the thermal fuse and put the test probes to each of the ends of the thermal fuse, if no continuity then replace the thermal fuse.
A vent clogged with lint can cause it to overheat.
Right after replacing a dryer element, always run the dryer on 'air fluff' / 'no heat', and go outside to verify there's plenty of air coming out your vent system.
If the vent's clogged, that new element can burn out very quickly.
