Question about Dryers

3 Answers

Amana LG8153WN Gas Dryer does not heat. Removed bottom panel and cleaned out area thoroughly. Igniter glows, then shuts off without igniting gas. Gas did ignite once or twice but not regularly. Checked and measured thermal fuse and operating correctly with continuity when measured via meter. Exhaust vent and hose are clean, no blockage. I temp removed exhaust hose and still no ignition. Hose length is les than 2 feet.

    In my request for support I had mentioned that the ignitor did glow (approxiamtely 30 seconds at start up).



    Your response said to jump out wires to see if ignitor glows. I disconnected 2 wires from the flame sensor and then jumped wires together and tried again. The ignitor glowed and stayed on rather than shutting down as previous. I metered the sensor with wires off and reads full continuity and then open after 30 seconds (which I assume during operations shuts off ignotor) at start.



    I reinstalled wires and tried again. This time gas did ignite this time so I reinstalled front panel but took a peak and flame was off again. After a few minutes, ignitor did glow again but no flame/gas ignition or heat. Cycle continued but still no gas ignition or heat



    Your response did NOT help to resolve the problem so seeking more advise.

    Thanks,
    Mike McD

    My spouse could not live without dryer (3 kids, lots of backed up laundry) so before I saw your second response, she brought in a technican to repair the problems. Not sure what was replaced/corrected but she phoned to tell me dryer now working. Because 1st response did not help to resolve the problem and we ended up bringing in a technican for repair before I saw your second response, I plan to forgo acceptance of solution and avoid the associated charge. Please let me know if this is fair/OK.

Step- 1 . First stop is to disconnect your vent and see how it performs,if that did not work. - Move to Step- 2. Step-2 : Sounds like bad coils on your gas valve - the reason it worked after you reconnected was that they had a few minutes to cool down again. Simple and cheap repair.

Here's a picture showing the resistance readings you should be seeing.

Step-3: Check the Resistance with the above picture reference. If it did not work then move forward. Ideally, there should be no difference between a dryers behaviour with the vent connected and disconnected. . This problem will often only manifest itself once the coils have heated up a bit. I'd throw a new set of coils on (about $15-20) and see what happens. Change the coils . Hope this helps.

Hi,

There is a flame sensor on the side of the flame housing. Jump the 2 wires out and see if the ignitor glows then. If so you need a flame sensor.
Check the following to address this issue


1. Gas valve coils
Igniter glows, then shuts off without igniting gas - the problem is probably with defective coils (black, located on top of the gas valve). It is recommended to replace all coils (usually two or three) if found defective.

Note: Sometimes the whole gas valve may be defective, thus not letting the gas out. However, this problem is not common.

2. Thermal fuse
Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.

Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.

3. Igniter
Igniter may burn out or break. Replace the igniter if found defective.

Note: Igniters are very fragile and break easily. It is recommended to handle the igniter only touching the ceramic part of it (usually white in color).

4. Flame sensor (or radiant heat sensor)
Replace the sensor (located near the igniter) if found defective.
Thanks for contacting Fixya

My Amana DLG330RAW gas dryer isn't heating up. The coil glows bright red for a while, but there is no flame. The coils seemed warm to me the last time I tried running it for a while, but I'd like to know...


Hello there:
Gas Dryers are very complex and there are several facttors involved here to make it heat Here is a list of possiable solutions for you to look at ok
Igniter Modern gas dryers use an electric igniter to ignite the gas from the gas valve. When it's working properly, the igniter glows bright orange. When it burns out, the dryer tumbles but there's no heat because the gas can't ignite. When the igniter burns out, you need to replace it. If the igniter is held by a tension bracket, you very well may need to replace the bracket too. The igniter is inside the dryer housing, near the bottom front, usually in a cone-shaped metal tube (the force cone). It's about 2 inches long. It's mounted to the far end of the burner tube, and it has two wires attached to it--or to the tension bracket, if there is one. Gas valve coils Watch the igniter. Does it glow bright orange, then shut off without igniting the gas? (When the gas ignites there's a large blue flame.) If so, there may be defective coils on the gas valve. Mounted on the top of modern gas valves, there are black electrical coils. The coils, when energized, open the gas valve. If one or more of the coils are defective, the valve doesn't open and the gas cannot ignite. Because it's often difficult to properly test the coils, it's usually best to replace both (all) of them at the same time. Thermal fuse On many dryers, there's a thermal fuse (a heat-sensitive fuse that blows if the dryer overheats) mounted to the exhaust duct inside the back cover panel. The fuse is about an inch long. It's usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, it has no continuity. When this happens, your dryer either just stops heating, or it doesn't work at all. Be sure to inspect the venting/heating system before replacing the fuse to put the dryer back into operation. (You can't re-set this type of fuse.)

I have a siemans wtxd5522uc 27" ultrasense gas dryer that the ignitor won't fire. What is the supply voltage to the ignitor? Is it usually the ignitor that goes or some sensor? Every thing else...


hi sir it ignites at the voltage bet 230v-250v.there will be a sensor problem where it cannot try to ignite try to clean ignitor area.. In a gas dryer, heat is provided by a gas heater that is controlled by an air shutter. The gas heater is generally the source of no-heat or drying problems. You can often correct such problems by adjusting the air shutter on the gas burner, which is located along the bottom of the dryer.
To adjust the shutter, take out the screws and remove the panel that covers the gas flame. Turn on the dryer so the flame is burning. If the flame has a deep blue color and you hear air whistling around the burner, the air/gas mixture is receiving too much air. If the flame has a yellow tip, the mixture is not receiving enough air. Turn the thumbscrew or loosen the two screws slightly to increase or decrease the flow of air to the burner. Keep turning until the flame is a light blue color, without any yellow, and the whistling stops.

Gas dryers use an electric ignition device rather than a pilot light to light the gas heater: An element becomes hot and glows like the filament in a lightbulb. Electric ignition systems are always sealed; you can't adjust or repair them. If an electric ignition device fails, call a professional service person for replacement.

I have a gas dryer that the igniter plug glows, but does not light the gas. One time when I had the front panel off the gas ignited and the dryer heated, but only burned for a minute then shut off. Now I...


with front off it will short cycle. If ignitor glows and then goes out without lighting, you have bad burner coils. The 2 black round things on burner assembly. Unplug unit then unplug coils and remove bracket with 2 screws. install coils and test.

I have an Amana Dryer Model # LGD20AW and when the dryer is first turned on the glow plug will heat up and ignite the gas but as the dry cycle continues the glow plug will heat up but no flame will ignite...


The glow coil or glow bar heats up and a sensor on the side reacts to the heat and then sends a signal to a gas valve.(solenoid valve) When the gas doesn't ignite when the coil is glowing... here are some reasons. 1. The sensor on the side of the burner assembly isn't working or sending power to the valve. 2. The valve is getting power but not opening. 3. The ignitor is not glowing hot enough to activate the flame sensor. Usually it is the sensor or the igniter not the valve.
