My Samsung electric dryer, model DV337AEG is showing an error code of hE, please help! No matter which cycle you try to run, the same thing happens: it will start up and run for approximately 20 seconds then it beeps and shows the above error code as well as flashing the word "Drying". Please help! Thank you!

Nothing you can do. The dryer is not suitable for the power source in your country. The AC cycles are not fast enough. Ask Samsung direct. They may be able to sell you a suitable motor.

Frequency errors (FC, FE, 1 FC)

These codes mean that there is an invalid power source frequency. To fix this, try restarting the cycle.
If the error code remains, visit the Support Center to request service.

timed cycle mean dryer not on sensor dry mode. check wire connection on moisture sensor bars (i think you forget to put 2 wire connector put together). when you use other cycle dryer use moisture sensor to dry cloths so sensor not working dryer will stop in 5 minutes or so because dryer think there are no wet cloths to dry. hope this help you.

Google your model number and how to retrieve the error codes. It sounds like either the heating coil or control board is bad. I have a different model that does the very same thing...they run until the cycle tried to turn the heat on then it causes an error. In my case it is the control panel and I decided since mine is old and we are a family 6 (lots of use in it) not to repair it.

Hi,

If you are having problems with your gas dryer not heating the most common problem is that the ignitor goes bad. Even though it glows sometimes 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 different things that can go wrong causing the dryer not to heat.

check out this electric no heat tip...

This one isn't going to be easy, you've already replaced the major things. I'm guessing there's a crack in some connector, or other defect, that heats up like the element and opens up- giving the same symptoms. It could be a faulty connection in the power feed to the element connector, or any other connection en route to it. You might see something suspicious. If you have some electronic skills, you might run the dryer until it happens, then quickly disconnect it, and while it's still hot, ohm out all power connections and wiring that could affect the element. You might get lucky and find the open line, being able to hone in on the bad connection, etc. Good luck!

not sure of the fault caode never seen it before but i would check he belt and drive motor and make sure there is nothing seized up

F03 MEAN SENSOR DEFAULTPUMP OR LENT

yes

you may need to replace both thermal fuses and or the heating element itself but check to make sure you have the proper temp rating for the thermal fuses
