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
Ignitors don't "blow flames". But a defective ignitor can glow but not draw enough current to allow the gas valve to open to the burners. Replace the ignitor. It's the "weakest link" and most likely part to wear out through use in the ignition system.
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...
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.
Well the fuse is not blown because you do get the glow (the dryer will run with the fuse blown). The ignitor is good. The flame sensor is good cause if it was bad the ignitor would not glow. Then what is wrong? It is the solenoid coils OR you ain't paid the gas bill. LOL You will know it is these if you sometimes get it to work once but then it don't work again or all of the above is working and you have the gas turned on.
1. Open the small access door in front of the dryer and start the heat cycle. The ignitor must glow a bright orange so that it is hot enough to light the gas. If there is no orange glow, then the ignior needs replacement.
2. If it glows then cuts off, then glows, again and cuts off, the thermocouple sensor wire is out of position. It needs to be very, very close to the ignitor. This thermocouple sends a temperature signal when it senses that the ignitor is hot enough to ignite the gas. Unplug the dryer. Re-position the thermocouple wire mount so that the thermocouple wire is almost touching the ignitor. You may also "bend" the wire. Plug power back on and heat.
3. If it still does not heat, then the automatic gas valve that is controlled by the thermocouple sending unit is broken. The automatic gas valve cannot be safely "fixed" and must be replaced. Hope it's just the thermocouple wire.
Hi, first thing to check is the venting. If the vent is plugged, it will cause the heat to short cycle. If later in the cycle, the ignitor glows but will not ignite the gas, you will need to change the coils on top the gas valve. This is a common problem. Please let me know if I can assist you further.
