lg dlg7188wm gas dryer not heating.
« on: May 23, 2012, 12:56:39 PM »

It went through the test sequence with all lights on the panel lit, and it alternated some code three times(which I believe is correct)--it was U:02 then 8:98, or something like that. Then it displayed nE after that sequence. I stepped through with the pause button as described, and got temps that were accuate (~20 C on both readings). The motor and igniter did what they were supposed to.

Any idea what could be wrong?  I changed thermostat, nd safety thermostat and also igniter and flame sensor...

I don't think that is a option with LG.


You would need to change the gas valve, part # 5221EL2002A

Ok, that's good to know. Don't see much for gas or LG dryers around here.
Seems any LG gas dryer I look up parts for does not show the coil separate, such as this model.


Good to know some models you can get just the coils for, thanks.

I was going to post an issue like this, but decided to bump the old thread instead.

   I just had one like this.  Same model and all. 

   The unit heated and then cooled and didn't heat again. 

This unit uses an odd valve/solenoid combo.  See at first I didn't catch that, and went to take a solenoid off and got that wonderful smell of gas .  So yeah, first time with this issue on this solenoid type. 

    I figured it was the operating limiter on the Flame tunnel.   These buggers will have flaky bi-metal that works and is in continutiy at room temperature but open quicly and take longer than normal to reset. 
  Since for LG and Samsung these limiters are so cheap, I went ahead and swapped it. 
The dryer heated up and ran just fine, for one load.
    Realized the issue was the coils.  I have seen this same issue in Whirlpool dryers caused by coils.  Hell we all probably change coils once a week. 

   Yet these coils were different.  Had to cut gas off in the back, a lot of unscrewing pipes and such.   

   After Iswapped it out, there were no issues.

So if you have an LG gas dryer, with the issue of unsustainable heat after initial heat-up I would look into the coils.
