DLG2102W Samsung Gas Dryer

12 posts in this topic

This dryer will not ignite.  The igniter comes on and then goes out but the valves do not open and release the gas, therefore there is no ignition.  The gas valves have been replaced and the control board was also replaced.  There are only 2 components left and I would like a definitive way to determine the problem.  Any ideas.

Did you check the radiant sensor on the gas burner funnel? It should be closed (continuity) at room temperature and open when it senses heat from the ignitor.

The igniter comes on and then goes out. My assumption is that the flame sensor sees the igniter and turns it off by opening the contacts.  What else would be turning off the igniter?

Dryer acts like it has a gas valve problem.  The igniter comes on then goes out but the gas valve does not release gas so it does not dry.  The gas valve was replaced (including the solenoids) and the control board.  It still has the same symptoms. I would ike a definitve way to determine the problem so I don't continue to just swap parts

I Have found foreign objects in in the gas lines causing this problem in LG dryers.

 

Take the gas valve assembly off while the gas is turned off and the unit unplugged. I then have someone turn the gas on for a short blast to make sure there is a good flow of gas to the gas valve.   

 

Or you can visually inspect it, 

 

Also check continuity of wires to valve, look for broken or burnt wires,

<<<The gas valve was replaced (including the solenoids)>>>

 

**********

 

On an LG gas dryer---the Gas Valve Assy---is of a one-piece-design (gas valve & solenoids are a single component).

 

For example---on a Samsung dryer---it's possible to replace the Gas Valve---without replacing the Solenoids (and vice-versa).

 

In any event---if the Main Board and Gas Valve Assy have been replaced---and the Igniter glows & shuts-off without gas ignition---I'd start looking at the Gas Supply to dryer (valve turned on?)

 

It is very/very/very rare---but on at least 2 occasions I've had a gas shut-off valve (on the wall/ceiling etc) fail.

In other words---in the "on" position---the gas valve was still "off".

 

Next---would be to verify correct gas pressure to the dryer (owner's manual specifies correct pressure).

 

If those prove "good"---then it will be necessary to begin looking into the various components within the dryer itself...

Never assume;

 

Uhmmmm, you just did :rolleyes:

 

This is an LG, (I'm pretty sure the Samsungs use this same style valve), doesn't use the standard coils - bad coils you need to replace the complete valve

No, I searched APP and that's what they pulled up for this model.  Error in their database.  

 

My comment about assuming was directed at his conjecture about about how the system works.  Hence the link posted to a more detailed explanation.

 

And can we please dispense with the smarmy "gotcha" comments?
