Most likely the gas won't come on if the igniter is bad.

Our Maytag model dg410 quit ingniting. Is it ignitor or something else?


Power from the control Klixon mounted on the blower housing energizes the gas valve assembly when the temp is below 105f and the dryer is set for heat. If that control is open then no power is applied and no heat. If a restriction causes the dryer to exceed 350 for some reason then the fuse next to the control Klixon melts. No power will get to the gas assembly but the dryer will run. On that gas assembly is an ignitor/flame detect sensor, an ignitor, and a pair of solenoids that open the gas valve. The flame sensor must have continuity. If it is open then no power will get to the ignitor. If the ignitor is broken you will also have nothing. The coils will not open the valve without a change in the resistance of the circuit. One of them coils has 3 wires and the other has 2. The sequence of gas valve operation is the flame sensor bi-metal has to open when the temp exceeds 1800f. this kills the power to the ignitor and flips the 3 wire coil so that the ignitor is now a thermocouple and the coils will yank open the gas valve. As long as that ignitor stays hot then the gas will continue to flow out the valve. If for some off reason the gas were not to ignite the ignitor would coold down and shut off the gas and that is your builtin safety. So what goes wrong? Blown thermal fuse, open control Klixon, open flame detect/sensor, open ignitor, or Intermittent coils,(the coils will get hot and quit with age.

Dryer is not heating up it runs does the ignitor heat up before gas valve opens because the ignitor never heats up


On my gas appliances, either there is a pilot light or the ignitor sparks (like a car spark plug) or glows after the gas valve opens. The ignitor does not heat up.

I've had some gas appliances that have had the valve stick. (On an oven, we tested this by tapping on the valve when the unit should have called for gas. This confirmed that the valve was bad and not the thermostat.)

I hope this helps.

Not heating up Gas Dryer


Modern gas dryers do not have a pilot light. They have an electronic ignitor (glow or spark). A glow ignitor turns on several seconds before the gas turns on and should get orange hot. A spark ignitor should make a clicking or buzzing noise.

Most likely the ignitor is bad but you can check it fairly easily to make certain. The best instructions I have found are at

http://www.acmehowto.com/howto/appliance/dryer/gdryer/check/ignitor.php

If it is the ignitor it can be replaced with a few hand tools. Remove the bad ignitor. Write down the make, model, and serial # of your dryer. Call your local appliance parts store to see if they have one it stock before driving over there.

Dryer is not heating, where is the ignitor and flame located


most models the ignitor and flame are located on the bottom of the cabinet, below the drum,
start the dryer and wait for a few minutes, see if you can here the gas valve turning on,,, if you do not hear a discernable click about 3 mins into a heated cycle, I would start with your ignitor,
since you did not suypply the model i canot tell you how to get into the unit, but most models , you can take off the front panel to gain acess to both the ignitor, t-stats, and gas valve coils
i could help you much better with maufacturer and model

but i do hope this helps

Have a Whirlpool Gas Dryer - model # lgr7646a spins but no heat


Thre is no pilot light. This dryer uses an ignitor (glow bar or coil).
Open the lower front "door" (small access door) and turn on dryer.
If the ignitor does not glow (bright orange), then the ignitor needs to be replaced ($60).
If it does glow, then the gas valve needs replacement ($60).
If it isd the valve, the internal spring is stuck. Do not try to repair it, you must replace it.

Gas dryer wont heat up, blows only cold air.what would cause this


Could be a bad hi limit thermostat. Could be a bad glowbar ignitor. Check the glowbar ignitor at the gas valve, is it glowing bright orange/red? If not. Replace the ignitor.

Roper gas dryer does not heat.


If the ignitor is not powering , go to the switch. That has to send power to the ignitor, then on to the gas valve.

Oven not lighting on Amana model agds902ss


Helloemauldin Welcome to Fixya
My name is Huum,

When you turn the thermostat on your range on it sends 120 volts to the bake valve and ignitor. The bake valve and ignitor are wired in series and the ignitor draws all the current and heats up. As the ignitor heats its resistance changes and when it is cherry red the current switches to the gas valve and it opens. The amp draw on the ignitor needs to be 3.2-3.6 amps for the gas valve to open. The gas valve has gas to it at all times. The gas valve should open within 40 seconds after the ignitor starts to glow.
If the ignitor is glowing red and the gas valve doesn’t open the ignitor is usually the problem. Sometimes the ignitor will glow red but the resistance doesn’t change and the gas valve doesn’t draw the current.

This is not a do it your selfer!

Whirlpool gas dryer won't ignite -no heat


Try replacing the ignitor. The ignitor has to glow red and draw enough current to open the gas valve. When the gas valve opens then the ignitor lights the burner. Replace ignitor.
