LG Front Load Gas Dryer - Short Cycling
« on: March 24, 2013, 12:45:32 PM »
I have a LG front load dryer that is short cycling.  I had a gas odor when I opened the door to the dryer.  I called a tech to check it out, he told me that the vent line was plugged and causing it. I cleaned it out and still experienced a gas smell from time to time.  I thought it might have been the gas valve malfunctioning so I just changed it out.  I am still having a gas smell and the dryer short cycling.  About 5 seconds or so.  I noticed that the lent screen had holes in it like they were burnt this morning.  For some reason it seems whatever is telling the flame to function is malfuntioning.  I snoop checked the gas line behind the dryer and its not the culprit.  Can anyone help me troubleshoot this problem.  Thanks.

What is the dryer doing that makes you think it is short cycling?

honestly its bc thats what the tech told me, he said the burner wasn't staying lit long enough, my quest is if thats true and I'm smelling gas, is it pumping raw gas in my dryer when the burner is suppose to be lit?  How long is the burner suppose to be lit?  Started with me noticing the clothes weren't getting totally dry. then I started smelling gas a short time later.  Thanks for the help.

LG gas dryers have a more radical temp rise versus an electric model. They are VERY sensitive to long vent runs or any blockages. If you have a long vent run, any blockages, or both, when the flame is called upon to ignite the slowed airflow will increase the temp rise causing the unit too run shorter than normal. It may also leave a CO or GAS like smell behind, not having the proper airflow. Shorten your vent.

I wish I could shorten my vent but where my dryer is placed, there is no way to do so.  I don't think its the vent, I took a blower and hooked it to the vent and got very little out, I still get the gas smell with it not hooked to the vent.  My house is also only a year and half old. So don't know if I have much lent build up in it.  Thanks for the suggestion though.

The thing about a gas dryer is that we are trying to make a flame burn sideways. The air being pulled through the burner tube is what does this. If you can't put any air out, you can't pull any air in so the flame starts to burn upward like a flame wants to do. There is a thermostat sitting on top of the burner tube that senses this and cuts the burner off. Thats why it short cycles. One way to check for vent problems is too run the dryer off of the vent and see if there is a difference in burner run time. Don't do this for very long because its not safe to vent a gas appliance into the house.

That makes total sense, I do have a long run with the vent.  There's nothing I can do about it.  How long is the cycle suppose to last?  I can probably find a extension and a brush for my drill and clean the line out.

So if it blows the flame out is it pumping raw gas into dryer?

It doesn't blow the flame out. The thermostat is like a switch and opens the circuit to the coils on the gas valve. I'm not sure why you are smelling gas.Not a problem that happens in dryers usually.

I am not understanding the smell either. It MAY be one of those things you happen to notice when digging around your broken dryer that MAY have always been there.... This is VERY common. Hell I have done it, only to kick myself!
