LG DLG7188WM gas dryer is not igniting

Checked all the normal stuff (vent, gas valve, coil/igniter, ohm'd solenoids). not getting power to the solenoid, so checked circuit board and not getting power to the plug/wiring harness that sends signal to relay. Anyone know how to ohm this out within circuit board?

    Hi Houcop,

  • houcop May 08, 2014

    Check the outlet and power cordtoo for voltage.

  • houcop May 08, 2014

    With power DISCONNECTED, the selonoid should show restance. All valves are Closed until power opens them.

  • houcop May 08, 2014

    Be sure to check the thermoststs. There is usually 2 one that turns the heat on and off (Expensive one) and the High limit that shuts down the dryer when it overheats.

  • houcop May 08, 2014

    There are videos on YOUTUBE that will walk you through it.

    Think i found the problem. One solenoid checks out, other seems to have a broken circuit, so guessing it isn't opening to allow LP Gas flow to igniter coil. Will get a new valve assembly and see if that fixes the problem. Thanks so much again. Really appreciate it!!!

There are 3 things that will make a gas dryer not ignite. 1. the main controller 2. high limit thermostat, which disconnects power to the igniter if the dryer overheats 3. the electronic or electric igniter. There are 2 types of igniters static that sounds like a ticking noise before it lights and a thermal that glows red hot to ignite the burner. Most dryers will attempt to ignite 3 times and will shut down if the burner does Not ignite to keep unburned gasses from being expelled.
With the front cover off also called the kick pan, look at the burner assembly and you will either see the spark igniter (like a giant spark plug) or the thermal igniter glow red hot. If the igniter does not activate, and the drum is turning, it is either the igniter, or the high limit thermostat stuck in the open position and needs to be replaced.
Both can be purchased from EBAY and will save you lots of money.

    Ohmed out both solenoids, one seemed to have proper connection, other didn't. Not sure how to interpret since could be NO/NC valve.

  • Weston Neiman
    Weston Neiman May 08, 2014

    Turned dryer on and check for voltage at back of circuit board where it sends signal to solenoids. Nothing, guess my problem is the main circuit board. Wiring diagram doesn't really show where positive feeds to that plug so couldn't ohm that to check if the circuit is broken. Don't know if I should purchase solenoid to replace or main circuit board. Both are about $125 apiece. was hoping someone might now how to test to verify which one of those two is the problem? Thanks!

SOURCE: dryer wont heat

About all that is left to replace is the flame sensor mounted at 9o'clock on burner flame tube, but I would double check your airflow, This is CRUCIAL to the normal operation of the dryer.
Also, a lint filter with an invisible coating from fabric sheets can cause an airflow disruption, try running without clothes and the filter removed.
Tip: Always provide the complete information provided on the manufacturers product information data tag, located on the unit, and not in the user’s manual. This will help you acquire a more accurate and expeditious response to your complaint.

SOURCE: LG DRYER DLE2532W DISASSEMBLY INSTRUCTIONS

DLE2532W is an electric heat model. (a gas model would be a DLG......) To get a rear control LG dryer apart: Open door and remove two phillips head screws at the 5 and 7 o'clock positions. Use a putty knife to release the clips holding the top panel to the dryer front by pushing the clips in at the seam of the dryer top and front, a couple inches in from each side. Swing top back. Remove two phillips head screws at the top, allowing front panel to pull forward. Unplug drum light and door switch and drum sensor plugs, allowing front panel to be completely removed and set aside. Now, look at the burner area at the lower right. Behind the gas valve you will find a small (about dime sized) high limit thermostat on the left side of the burner cone. It has two wires attached and has a small pin in the center of it. (Only on gas models) Push the pin in.
Now, if that get's you ignition again, CORRECT VENTING ! Get rid of flexible vent material. (use only rigid aluminum vent pipe and elbows) Clean out vent pipes and outside vent hood. Outside vent hood should be the kind with a four inch flap for the opening, not a two inch flap. Tripping of the high limit thermo is almost always caused by inadequate air flow.

My lg gas dryer will run alright just will not dry clothes.The flame will ignite for maybe 10 seconds or so and then shuts off.It keeps repeating. I know it sounds like my flame sensor needs cleaned.


I would check the vent and be sure it is open and free of lint. That would be the easiest thing to check. If you have the flexible white duct replace it, it is a lint trap.

What part provides power to coils to ignite gas, and what would cause the igniter to suddenly shut off after five minutes?


Coil is probably bad, they get a crack in them and will not work. If you have a an ohm meter you can disconnect power and check it

Gas Dryer no heat: or shuts down soon after heating CHECK:

Thermal Fuse
If the air flow in the dryer is restricted, the temperature in the heating chamber can get hot enough to blow the thermal fuse. If the fuse blows, it cuts power to the coils that control the gas valve. The fuse is usually mounted to the exhaust duct just inside the back panel. You can check its continuity with an ohmmeter. If, after disconnecting the fuse, you get any reading other than 0 when you touch the leads of the meter to its terminals, it has blown. There's no way to restore it -- you'll have to install a replacement.
Igniter and Gas Valve Coils
TEST with a multi meter: The igniter is an electric conductor that works like the element in an electric heater, glowing hot enough to ignite gas when you turn on the dryer. This conductor can burn out, and when it does, it may glow, but it won't get hot enough to ignite the gas. At times it may give a reading of continuity yet fail mechanically and not get hot enough to ignite flame though it gets hot and glows and even may show Ohms or continuity ( close circuit) ?
Occasionally, the Gas safety valve and the electric coils that control the gas valve are defective -- they can wear out when the dryer gets old. When this happens, the igniter glows, but gas never enters the heating chamber or does not stay consistant.
Performing a continuity test on either part will help you determine whether or not you need to replace it. But the coils should also be tested for amount of resistance as well as Ohms. As they may be showing ohms yet not putting out enough resistance to keep proper gas pressure flowing. Most coils should show at least 1300 ohms ( GIVE OR TAKE 150 OHMS). Anything significantly less Thus u get an ignition but then it soon goes back out. The flame does not stay lit.
Air Flow and Heat
The motor that drives the tumbler also drives a fan that circulates air through the heating chamber and the tumbler and expels it through the vent. If the air can't circulate, perhaps because of lint blockage, the heating chamber overheats, which prompts the cycling thermostat to turn off the gas. The thermostat resets when the chamber cools, but the chamber heats up quickly and the thermostat again shuts off the gas. The result is that the temperature in the tumbler doesn't stay hot, and your clothes take longer to dry, if they get dry at all.
Warning
There's a big difference between a dryer that doesn't heat up at all and one that just doesn't get hot enough to dry your clothes. In the first instance, the problem is usually a defective part, and things should be back to normal after you replace it. In the second instance, the problem is caused by restricted air flow, and you need to clear the lint filter and vents and take steps to prevent lint build-up. If you don't, you'll use more energy for drying than you need and the dryer may continue to malfunction. Worse, you may have a dryer fire.

My lg gas dryer model no dlg3744w will not heat


There are three high limit thermostats. Check all three for continuity. They should read closed (0 ohms). Check the flame sensor. They're cheap so you could just replace. It needs to close before the first solenoid opens and then open before the second solenoid opens. Again, easier to replace. Check continuity on the solenoid coils. They should read 1.5 K ohms. I replaced two gas valves before I recognized a "new" gas valve might not be really new.

No heat


Check the following:
  1. Power. Make sure there's power going into the unit from the outlet. Check fuses or breakers of the branch circuit where the the outlet is connected.
  2. Igniter. The igniter glows bright orange when working. If it burns out, the dryer tumbles but there's no heat because the gas can't ignite. Replace the igniter and the bracket holding it. It is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube. It's about 2 inches long and mounted to the far end of the burner tube, withtwo wires attached to it.
  3. Gas valve solenoid coils. If the igniter glows bright orange then shuts off without igniting the gas, there's a defective solenoid coil om the gas valve . It is a black electrical coil mounted on the top of the gas valves. When it is energized, a clicking sound can be heard and it opens the gas valves allowing gas to flow and be ignited. If defective, the gas valves cannot open not allowing the gas to be ignited and heat up the dryer. If that is the case, replace the solenoid coils.
  4. Thermal fuse. Mounted to the exhaust duct inside the back cover panel about an inch long. It is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, it has no continuity. Your dryer either just stops heating, or it doesn't work at all. If it is the case then replacing it is the only viable solution since it cannot be reset.

Whirlpool Gas Dryer


Yes, that is most likely the problem. Once the glow bar igniter glows so hot, the switch opens & drops power to the igniter.(The radiant sensor has continuity while cold & open when a flame is present.) At the same time, by opening it redirects power to the valve coils allowing them to open & gas flow to the burner assembly. The dying glow of the igniter fires the gas. However, if your igniter glows, the radiant sensor is good. In this case, you'd need to replace the gas valve solenoids.
