GE gas dryer, no heat, new ignitor

My gas dryer stopped heating so we took the burner assembly out, had continuity tested and everything but the ignitor checked out. Believe the ignitor burned up when a charcoaled mouse was discovered in the burner tube. Have installed the new ignitor and it still won't glow. Dryer works away flawlessly, just no heat from the ignitor.

    My brother in law took the whole burner assembly to his appliance repair shop, they tested all the parts and pronounced them working except for a new ignitor I had purchased. They replaced that with one of their own (functional), but when it fired up it shattered. Long story short, 3 ignitors later, I have one installed and it just won't glow. This is getting very irritating, so I had a vodka & pomegranate juice. Now everything is better...the ignitor still isn't glowing but it is much less irritating.

    My ignitor is great--since all the burner assembly parts tested out okay, I decided to snoop under the top to look for a thermal fuse that might have tripped when the mouse (R.I.P.) burned up the original ignitor. Didn't have to get that far because my bro-in-law hadn't reconnected the control panel with the rest of the dryer. Plugged it in, fired it up and the glow bar is glowing an eerie orange. Thanks for the suggestions, I have mucho laundry to do!!

Hi!! make sure that you have 120 volts going to the glow ignitor.the gas valve will not turn on the gas if the ignitoe wont glow..if it glows the check yout coil boosters they are round and are located by the gas valve.then if not you have a bad timer.they are usually round and are black..good luck..

A whirlpool gas dryer will not heat up


If your dryer is not getting any heat, you need to make sure there is nothing blocking the vent. IE: LINT. Air flow is key to efficient drying. Make sure the dryer settings are appropriate for the clothes you want to dry. The timer selection, fabric selection, and the temperature selection all play important roles in proper dryer operation.
Check the heating element, burner operation, ignitor, thermal fuse, and the wiring (power cord).
• Heating element (For Electric Models)
• Burner operation (For Gas Models)
• Ignitor (For Gas Models)
• Thermal fuse
I WOULD START WITH:
To protect from over-heating, many dryers use what's commonly called a thermal fuse. If the thermal fuse gets too hot, it will blow, and completely shut down your dryer until it is replaced. This fuse is often mounted within the exhaust duct in the back panel. It's about an inch long, and is usually found within a white plastic housing. When fuses blow, it means they have no continuity and no power will flow through it. A bad thermal fuse needs to be replaced. When replacing this fuse, check the dryer vents to make sure there is no lint buildup which can cause the heat to stay trapped and blow the fuse again.
Visually inspect your heating element for any broken or burned areas.Check the coil for continuity with a Volt Ohm Meter. If there's no continuity, it means that the element is bad and you need to replace it.
If the ignitor is cycling without the burner lighting, you probably have defective electrical coils in the gas valve. These coils look like black cylinders with wires coming out the top of them, and are located near the burner valve assembly. When they get power, they open up and allow the gas to get through to the burner. If this is a new installation, make sure the gas valve is turned on.

Flame goes out within a minute


Hello. You likely need to replace the gas valve safety coils. You can do one of 2 things. You can purchase a voltohm meter for under 20 dollars, or you can start replacing components within the burner assembly until you find the problem. The valve is very reliable and rarely fails. One of the most common parts that need replacing in the burner assembly is the valve solenoids.
If you choose to purchase one for testing purposes, I'm posting a link now that will show you exactly how to use it. Dont be intimidated by it (you might already know how to use one, but I dont know that). Here is the helpful video. It's easier to see than explain in words.

Here is a helpful link on disassembling your dryer.
http://applianceassistant.com/videos/appliance_repair/whirlpool_dryer/index.php


Your dryer will have a cap on the lower left side of the front cabinet. This is a viewing port for observing the burner assembly. I also did a parts search with that model number and found 2 close matches. You will need to look at these links, and then decide with your model number which one is yours. They will help you determing where all of the parts are located within your dryer and burner assembly.

IF THE IGNITOR GLOWS, you know that it's okay, you also know that the thermal fuse in the back of the dryer is okay.
NEXT, you'll want to see if it turns OFF. If it didnt I'll cover that later. If the ignitor clicks off after a few seconds of glowing bright orange, You know that the flame switch mounted to the left of the burner tube is OKAY as well.
At the moment the click of the flame switch is observed, the burner valve should release gas for burner ignition. If the ignitor turns off with no ignition, and you are positive you're getting gas supply to the dryer, you likely will have to replace the two coil valve solenoids on the top of the burner.
The two safety coils may gradually fail over weeks, or even months giving longer dry times and only partial heating. As safety coils are failing, they'll work fine for only a short amount of time, and then after about 30 minutes of cycling on and off to maintain the drum's temperature, they will break down and cease to open the valve leaving you with cool or wet clothing at the end of the cycle.

IF THE IGNITOR GLOWS, BUT NEVER CLICKS OFF you likely have a bad flame switch (flame sensor).

Here are some helpful links for part replacement in the burner assembly; You will unplug the dryer before any continuity testing or unit disassembly. If you test for continuity on a live circuit, that poses a big risk to you and it will fry your meter.
http://www.youtube.com/user/RepairClinic#p/search/1/tMqublMvau0 Flame sensor replacement. To test the flame sensor (located on the burner tube), unplug the wire connector, and put the voltohm meter test leads to the 2 prongs and test for continuity. If it has continuity, it's okay.

http://www.youtube.com/user/RepairClinic#p/search/0/Mj7Q-SexmGQ Gas valve solenoid replacement video.

http://www.youtube.com/watch?v=iK9q6K7iIrQ&feature=mfu_in_order&list=UL Ignitor replacement video. You test the ignitor the same way as the flame switch. Disconnect the plug, and test for continuity on the 2 prongs (the ignitor side of the connector). Continuity means it's good.

I hope that you found this helpful, and that you can solve your problem with it. I will be happy to help you further if you need any assistance. Let me know if you need help, or you get your problem solved. It really makes my day to help someone out.

Thanks,

Mike

I have a whirlpool gas dryer that will spin but not generate any heat? maybe the ignitor or the burner?


it could be:
1. thermal fuse (check continuity ~0 Ohm)
2. gas valve coils (check continuity with Ohmmeter set to x100 or x1000)
3. Ignitor (check continuity, can be up to 80 Ohm)

Much less likely:
4. radiant heat sensor (should open when heated by ignitor).
5.cycling or high limit thermostat (check continuity, ~0 Ohm)

Drum turns but does not heat the air. I replaced the ignitor, but no help there. Whirlpool gas dryer model 63003W0


If the ignitor glows but does not light the burner you need to replace the gas valve coils.
If there is no glow you must check all the thermostat safeties and thermal cutout fuses for continuity with a ohm meter. No continuity is a bad component. Remove at least one wire from each component before testing.
Unplug the dryer before any test.

Gas dryer quit heating


Hi there,

Well if your dryer tumbles, but there is no heat then you may please check out the following -
1. First of all you can check out for proper air flow - Check the vent for proper air flow by placing your hand over the exterior vent while the dryer is running. You should feel a strong flow of air. If not then check the lint trap. It is located either on top of the dryer or possibly just inside the door. Remove any lint that has built up in the lint trap. Cleaning the lint trap should be done regularly, even as often as after every load. Do not operate the dryer without a lint trap in place.
2. Secondly you can check out the Ignitor - gas dryer blows air through a burner assembly to heat the air. The burner assembly consists essentially of a gas valve, ignitor and a flame sensor. If any part of the burner assembly malfunctions, the result will be low or no heat and slow drying of the clothes. Post comments for further help or information.....

Good Luck!!

Thanks for using FixYa!!

Dryer doesnt blow hot air.


I find that quite often the ignitor is out of alignment or the glass window is covered with lint.
a gas dryer blows air through a burner assembly to heat the air. The burner assembly consists essentially of a gas valve, ignitor and a flame sensor. If any part of the burner assembly malfunctions, the result will be low or no heat and slow drying of the clothes.
There are two common styles of ignitors, glow ignitors and spark ignitors. The ignitor ignites the gas either by heating up and glowing, or by sparking. If the ignitor fails, the dryer will not heat.

The easiest way to check the ignitor is to observe it. Remove the small access panel in front, select a high temperature setting and start the dryer. Watch the burner assembly, shortly after starting the dryer the ignitor should begin to glow or spark. If you see it glow or spark, then the ignitor is working.

No Heat


Hello
Welcome to Fixya


Remove the vent line from the rear and try the dryer.
If it heats then that means there is a clog or kink in the vent line blocking the vent air from exiting which will stop the dryer from getting hot!
If not then it's another one of these problems.

Defective Ignitor (Gas Only)
When heated the ignitor used on your gas dryer must obtain a specific high temperature
in order to activate the flame sensor. This ignitor is fragile and susceptible to cracking.
A hairline fracture that is barely visible to the naked eye is enough to change
the resistance of the ignitor to a point that is will not work properly.
You can test the resistance of your ignitor. You should get a reading of 50-400 ohms of
resistance.

If the ignitor gets hot and then goes off after about 10-15 seconds and there is
no ignition, the problem is probably not the ignitor. It is most likely the gas valve
coils that are defective.

If the ignitor comes on and stays on, it is the flame sensor that is defective.

If the ignitor is not getting hot it could also be one of the thermostats that is defective.
The power for the ignitor is passed from the timer, through all of the thermostats,
limit switches and fuses to the ignitor. So if you are not getting power to the ignitor
during ignition, you should check the continuity of the individual thermostats and fuses.
DRYER DOES NOT HEAT



Defective Gas Valve Coil (Gas Dryer Only)

If the gas dryer will light once but will not relight until it cools down, it is likely the gas valve coils are faulty. These coils loose some strength when subjected to heat. When they become old, the addition of heat may be enough to prevent them from opening the gas valve when hot. However the coils still work when when cool.

An easy way to diagnose the coils when the burner is not lighting, watch the ignitor. If the the ignitor glows for 10 to 15 seconds but no flame is created, then the coils are faulty. If the ignitor is not glowing the problem is elsewhere.

Recent Customer Symptoms:
The dryer burner doesn't always come on when starting. If the burner does come on, once it goes off if won't come on again until the dryer cools down.



Defective Flame Sensor (Gas Dryer Only)
The flame sensor's job is to monitor the ignitor for sufficient heat
to ignite the gas. A properly operating flame sensor will pass a
continuity check under room temperature.

Common Symptoms
If the flame sensor is defective in the open position,
the ignitor will not get hot when the dryer is started.
However, if it is defective in the closed position the ignitor
will get hot, but the flame sensor will not allow the flame to ignite.
In this case, the ignitor will usually stay hot for a long period of
time.



Defective Thermostat
The thermostats are responsible for maintaining the proper temperature
in the dryer. Check the exhaust temperature of the dyer and if the
temperature is above 150 degrees, you will most likely need to change
the operating thermostat.

The thermostat can also fail in the opposite mode.
It can prevent the element from heating at all.
A failed continuity check at room temperature will verify this condition.

There are some special thermostats that are single pole double throw.
These thermostats are often used to control the timer when set to the
Automatic Dry cycle. If the dryer timer will advance in the Timed Dry
cycle but not the Automatic Dry cycle, then the thermostat could be the
problem.


Defective Thermal Fuse
The thermal fuse is in series with one leg of power to the motor.
If the fuse is open (no continuity) the motor will not run.

Location:
The thermal fuse is located in different locations according
to the model and brand of dryer.

Solution:
Check the thermal fuse for continuity with a volt/ohm meter.
If it is open, it will need to be replaced

Maytag Gas Dryer SDG515DAWW - heating stopped


The heat is regulated with a Klixon mounted next to the blower housing near the vent pipe so it can judge the temperature of the air coming out of the drum.Right next to it is a melting type fuse. If the dryer runs and gets too hot the fuse will melt.But the dryer will still run. So if the fuse is good(continuity) and the dryer control(cycle) thermostat is also good then you should have power going to the gas valve assembly when the machine is running unless the timer is in the no heat or wrinkle free/cool down mode. When the gas valve assembly is energized the flame sensor a%20flame%20sensor%202.bmp flame sensor mounted outside the burner chamber detects the heat from the ignitor. When the heat is very intense then the sensor shuts down the igniter
a%20igniter.jpg Igniter and that frees up the power so that the coils can be fully energised and open the gas gates. The gas comes out and hits the red hot igniter and you have ignition. It stays on for maybe 2 or 3 minutes or until the control thermostat is satisfied and shuts down power to the gas valve assembly.
