Dryer ignitor lights and then goes out no heat changed coils

Ignitor lights and then goes out. i changed coils and still same problem. i have a noise coming from the gas vavle as the ignitor lights the noise goes away then as ignitor goes out the noise from the gas valve is back. im thinking i must have a problem with the gas valve? i unplugged the coil with the two wires while in service and the noise stops. could it be the gas valve itself is bad if not what is the problem.

Whirlpool dryer heating sporadically?


Remove the lower front panel and turn dryer on. The ignitor should glow bright orange first. After Ignitor glows brightly the next thing will be the flame lighting as the gas valve opens with a click. All this should happen within about a minute or so.

If flame comes on but goes off quickly It's likely one of the Gas valve coils is opening a break in the coil as the coil heats up. This coil will shrink when cool and be able to run again. The coils are purchased as a kit.

If ignitor goes off and no flame comes on the coil kit is likely needed because one coil is fully broken inside its case. If flame goes on but shuts off shortly the problem is as described above and the kit is needed.

There is a flame safety assembly on the can above the burner. If the airflow is poor. the flame tip may activate that safety and turn the flame off. Or the flame switch may be open and not allow the flame to come on at all.

The Flame switch can be tested for continuity with an ohmeter but the valves may ONLY show bad with power applied and can not be tested with a meter as they will test good.. Good Luck

Ignitor works, lights the gas, then when the ignitor goes off, so does the flame.


Hi Stanley,
the problem with the dryer flame going out is caused by defective coils on the gas valve and the gas valve coils should be replaced

No Heat- Dryer will not dry clothes, the pilot light will light for a few seconds with a glow. I have changed the coils and the thermal fuse. Don't know what else to try.


Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip.... If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat. check outthis electric no heat tip...

First cycle dryer will fire as normal. each time after it will not light. glow plug is working but no gas allowed to turn on. i'm feeling it may need coils for gas valve?


Hi,

I would change the ignitor first...

Will not light


First check for a blown duct fuse Number 6.
themobilian_47.jpg
If that turns out to be good I am going to look at the flame sensing device mounted on the side of the burner housing

If that turns out to be ok I look at the ignitor
themobilian_49.jpg
themobilian_50.jpg
When the control thermostat calls for heat power goes through that fuse and to the gas assembly. All of the components are powered up at once. The coils however will not release the gas untill the resistance changes in the circuit. To do that the flame sensor and ignitor must drop out of the circuit. That gives enough energy to yank open the spring loaded gas valve and raw gas flows out onto the screaming hot ignitor. Whoosh!!! Houston we have ignition!. So if it heat a little bit but quits heating them coils are bad. themobilian_51.jpgthemobilian_52.jpg
I am including a video that shows how to access and replace them

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
