Gas ignitor how to change gas ignitor

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

The ignitor needs to get up to a predetermined temperature prior to opening up the gas valve, you could have a weak ignitor. You need to see if the PC board is sending 24 volts to gas valve. If it is but no gas, bad gas valve. If not, bad ignitor or bad PC board. I would change out the ignitor first since it is a wear item as well as the cheapest component.

you have a bad gas valve or the ignitor is bad,just because it glows doesn't mean it's good,it opens the valve by amps.you need an amp meter with a clamp on attachment,stick one of the ignitor wires in the clamp and read it out,it should be 3.5 amps but if the ignitor is new i would change out the gas valve,also check the wires on the valve and read out the valve with a meter.also if the ignitor is glowing but the flame isn't liting you're having problems with the gas coming in,when the ignitor reaches 3.5 amps it opens the gas valve and the flame ignites,check the burner tube to make sure the old ignitor didn't burn a hole through it,you can check the orifice to make sure it's open,read the valve out and if all are good change out the gas valve.let me know what you find

IF MOTOR RUNIN AND NOT HEAT YOU NEED CHEK:

1-THERMAL FUSE.
2-SENSOR FLAME.
3-IGNITOR.
4-GAS VALVE.

IN THIS ORDER.

jumptrout51 is correct with the the round ignitor. Using a clamp on digital ampmeter, you should see the amperage use go from zero to at least 2.5 amps after you turn on the broil, then gas valve should open. (the flat ignitors actually require at least a 3.2 amp minimum) Very unlikely the electronic control has anything to do with your problem. Low voltage is not real likely if the oven ignitor is working. Most likely you have a bad ignitor or a poor electrical connection.

HI, Remove the front lower panel. Start the dryer and see if the ignitor glows. If it glows but the gas valve does not open, Change the coils on top of the gas valve.
If the ignitor does not glow, test the ignitor for 120V. If there is voltage to the ignitor but no glow, change the ignitor.
If there is no viltage to the ignitor, check continuity on the thermostats and the fuse that are located on the blower housing. Also test the sensor located on the burner.
I hope this helps. Please let me know if I can assist you further.

I think you are talking about the oven safety valve or thermal valve. before you change you oven safety valve, I would check the Amperage on the oven ignitor first, install AMP meter on one of the ignitor wire, it should draw above 3AMPs, if not then you have problem with the oven ignitor and not the safety valve. we hardly change the safety valve, I'll try to change the ignitor first. Have fun.

Could be a bad regulator.

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!

According to the model number you supplied it looks like your oven use a glow bar ignitor not a pilot light. In that case there is no place to hold a fire. what happens with these when you turn the oven on 120 volts goes to the ignitor causing it to heat up ,the amp draw across the ignitor causes the gas safety valve to open, and then lights the gas. So if you turn your oven on you should see a bright red glow if not probably the the ignitor, to check it you would have to verify you actually have power going to it. If the ignitor glows but the gas valve does not open you will still need to replace the ignitor has to pull about 3.2 amps across ignitor to open safety valve. Your broil burner works the same way. And most of the ovens the floor of the oven comes out to allow easier acess to the ignitor. also if you have to change the ignitor put just a dab of dish detergent on the screws to help from stripping them
