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.)
Hello there: Gas Dryers are very complex and there are several facttors involved here to make it heat Here is a list of possiable solutions for you to look at ok IgniterModern
gas dryers use an electric igniter to ignite the gas from the gas
valve. When it's working properly, the igniter glows bright orange. When
it burns out, the dryer tumbles but there's no heat because the gas
can't ignite. When the igniter burns out, you need to replace it. If the
igniter is held by a tension bracket, you very well may need to replace
the bracket too. The
igniter is inside the dryer housing, near the bottom front, usually in a
cone-shaped metal tube (the force cone). It's about 2 inches long. It's
mounted to the far end of the burner tube, and it has two wires
attached to it--or to the tension bracket, if there is one.Gas valve coilsWatch
the igniter. Does it glow bright orange, then shut off without igniting
the gas? (When the gas ignites there's a large blue flame.) If so,
there may be defective coils on the gas valve. Mounted on the top of
modern gas valves, there are black electrical coils. The coils, when
energized, open the gas valve. If one or more of the coils are
defective, the valve doesn't open and the gas cannot ignite. Because
it's often difficult to properly test the coils, it's usually best to
replace both (all) of them at the same time. Thermal fuseOn
many dryers, there's a thermal fuse (a heat-sensitive fuse that blows
if the dryer overheats) mounted to the exhaust duct inside the back
cover panel. The fuse is about an inch long. It's usually embedded in
black resin and mounted in a white plastic housing. If
the fuse has blown, it has no continuity. When this happens, your dryer
either just stops heating, or it doesn't work at all. Be sure to
inspect the venting/heating system before replacing the fuse to put the
dryer back into operation. (You can't re-set this type of fuse.)

If you are having problems with your gas dryer not heating
the most common problem is that the ignitor goes bad. Even though it glows
sometimes it is still not working properly.
If the ignitor comes on and after a period of time shuts down, waits, and repeats the cycle, then forget trying to read the coils.
Just replace them. Works 99% of the time.
If the ignitor stays on, and will not shut off at all, then the sensor mounted on the side of the heat tube is bad, and needs replaced. It looks like this.
It's likely one of the 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. In your machine, it appears Amana doesn't sell the coils as a separate item and the whole valve needs to be replaced. The part number is Y504091.
Disconnect power and turn off gas before working on this dryer. Working on gas dryers is not recommended for people who are not professionals.
Service on gas appliances should be undertaken by professionals only due to the danger of gas leakage which can cause fires or death by asphyxiation.
At front, remove 2 screws near floor at the bottom of the lower front panel. Pull bottom of panel toward you and down. The gas valve should now be accessible on the left. Take care not to touch or hit the ignitor or you will be replacing it also. It is VERY brittle.
When you say "starter" I assume you are talking about the "ignitor" and it is glowing.If the ignitor stays glowing continuously then the radiant heat sensor, normally closed, is not opening OR if the ignitor lights up than turns off after about 10 seconds but no flame, then the coils (doesn't matter which one of the two) are bad. The coils are located on top of the gas valve and the radiant sensor is located on the side of the burner chute....Good Luck The Squirrel
