Amana furnace will not light. The ignitor comes on but that is all, the gas valve doesn't open.

Check gas pressure. If no gas, new valve doesn't help.

If your getting 24 Volts to the gas Valve and the gas Valve is not opening replace your gas valve If your not getting a full 24 volts check your Transformer and the ground to the gas valve.If the gas valve still does not open change the Gas valve.

Try blowing out the jet Burners with compressed air especially the one nearest the Ignitor. Right through where the gas comes in. These can get dusty and cause ignition failures. Also check to see if the Ignitor is in the path of the burner and has not somehow gotten bent. 100 or so ohms on the Ignitor should be good.

Hello, it is possible that even tnough the ignitor is glowing it might be too weak to ignite the burners. I would cneck the resistance of the ignitor with a multmeter, should be between 40-90 ohms typically

most likely it will be the ignitor,even though it glows it doesn't mean the ignitor is good.it works on amps.a flat ignitor takes 3.2 amps to open the gas valve and a round ignitor takes 2.5 amps to open the valve,the only way to check it is to replace it and i would or if you have an amp meter with a clamp on it you just stick one of the wires going to the ignitor inside the clamp and it will tell you how many amps are coming out of the ignitor.buy a new ignitor and you should be fine.it calls for ignitor part number 31940001 and it's around 50 dollars.

Hello
The click is either the gas valve opening or the ignitor trying to ignite.

From what you decribe,im going to say you have a bad ignitor.

If the gas valve is indeed opening,then you need igniton to light the gas,
which leads me to say bad ignitor.

Hope this helps.

The sequence is Igniter comes on, valve comes on, flame sensor senses flame. If no flame is sensed after 3 tries, a lockout occurs. If you have a volt meter, check for 24-27 Volts AC coming to the gas valve, if your getting voltage to the valve but no gas, your gas valve is defective. It could be a intermittent problem, no matter, still a bad valve. if no voltage to valve, defective circuit board. 

The ignitor has to be hot enough to open the gas valve. It is glowing some but not enough to open the valve. Replace the ignitor.

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!

Please remember to leave a solved rating before you leave!

Buy a new ignitor here; The Ignitor Store. Or talk an Amana dealer/Contractor to sell you one. They can range from 15 to 35 bucks! Depending on their mark-up. Give them your model number, and or ignitor part number. Their simple to change out, good luck, please contact if you have any questions.
