LG Dryer long dry time

[rego]

Model: DLG2526W
Anyone have a tech sheet or service manual for this model?  They are having long dry times.  Dissasembled and it's very clean, blower good, all components check out, good flame, etc. and venting is clear.  Told them to try using the time dry for awhile and see if it makes a difference.  Could not find tech sheet with the unit so would like to know how to run a diagnostic.  sensor is clean and checks out.  Do these unit's have problems with the coils closing when they get hot like whirlpool's?
Thanks

make sure the dryer is venting properly first.  that said, i have had one that was fixed by changing the valve and coils.  not sure if it was the same model as this, but the coils were not available.  had to by the whole valve.  haven't heard back from the customer and its been a while.

Looks like only the gas valve on this one too. I think he'll let it go for now. Thanks!

Still looking for tech sheet or manual for this model closest I can find is DLG2525...are the test's the same?  Would love to put it into diagnostic mode.  Customer just called and no heat at all now.  Will start with basics but would like to verify the control board as well.
Thanks

The valve resistance is 1995 ohms and the ignitor is 185.

Thanks JW, looks like the thermistor should read normal resistance as most...just bother's me I can't get into diagnostic...I have not worked on many  LG so would love it if there was a tech sheet in the machine...oh well, piece by piece I'll figure it out:)

Fearless leader has a bunch of the manuals. I have 30 or fourty manuals and I have compared many of them. They all seem to be the same:

I haven't read that many but a half dozen or so and figure the spec's are all pretty much the same so I can isolate the components and work from there.  Just love those diagnostic's (when they work).  Thanks JW!

Have been talking with a DIYer tonight about a bad timer on a Fridgedaire washer/stackable...anyway would you double check what I've been telling him is putting him on the right track...been a long couple day's Halloween, and running calls for another company while he is having a grandbaby while his son is out of country (military)  getting a little punchy:)

All LG gas dryers are pretty much the same.  The test modes doesn't do much.  Never used the test mode.  It just comes naturally that if no heat, check the hi limit and work your way from there. 

[rego]

Will do...finally got some sleep so am feeling a little more clear in the head for what that's worth.  I'll let ya know, I'm leaning towards hi limit w/ the reset, thermistor, or coils (new valve $$$)...who wants odds
 
Thanks Folks

I would put a safe bet and recommend you replace the following parts:

The hi limit switch
The gas valve
The drive motor
The control board
The display board
The ignitor

Did I miss anything??

This one is driving me crazy.  Customer finally wanted me to take a look.  It would fire for a couple minutes then stop, would try again, igniter glow's and nothing.
Unhooked vent from wall and cycled well and ran well.  Found a huge clump of lint at the outside vent. customer cleaned out and all was well for awhile.  Then same problem.
Brought my lint eater and cleaned the entire vent system and got a decent amount out.  Ran unit and still same problem.
All component's check within spec's so thought maybe the coils were going bad and not opening when hot.  Replaced gas valve no luck, same issue.
No vent blockage, new gas valve no change, all components check out and within spec.
Ran a diagnostic per dlg2524 manual and the first number's flash between18:98 and 1U:01; second moisture 255 (specs 70-239); drum temp between 30-31 (not sure if this is in celsius) drum was actually at room temp.
The first number's don't make any sense to me for a fault...am I looking at a bad control board or possibly weak high limit thermastats?
I jumpered the resetable therm. and no difference, could it be the automatic reset high limit on the blower?
So lost, could really use some help...must be something simple I'm missing...help!
Gonna try and run a video of the diagnostic I did.
Thanks folks!

Have you tried run it with exhaust off

Yeah, that's how I found the blockage.  Vent is all clear now from connection to outside.  Tried with disconnected again and still having same problem.  Could it have done this long enough to weaken the thermal cut out
