Kenmore 74812 Gas Dryer. Was told it ignites, clicks, but no 'whoosh'...hence no heat. The rods that go up inside the coils won't come down ..was told they should. Would need to replace whole burner assembly..but found I could get the Valve assembly with pipe and the repairman could reinstall. Was also told by a parts order man that I could replace the coils and that would fix it. However possibility gas could leak if I didn't know what I was doing. What do you suggest?

check igniter, flame sensor and gas valve and coils? if no gas from valve you will have no flame ignition. hence no heat, bad igniter will not ignite flame either, bad sensor will not detect flame hence no signal to ignite check all with multi meter
If your dryer is not heating assuming is a gas dryer. It could be due to
The electrical fuse igniter is not working or no gas is going in.
Need to remove the front bottom cover and check that the fuse is igniting when you turn on the dryer. You should hear a clicking noise just before the igniter turns red ( glowing) to receive the gas and create the flame to then produce the heat. If you are not able to see the fuse/igniter conduct this process, you might need to replace it.
You would not hear the click if the ignitor was bad. It won't click until the flame sensor get heated up by the ignitor. So that tells me the thermal fuse ain't melted. I would say them coils on the gas valve are the problem.
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 Sensor for heating element cut-off is bad. It wrongly detects the unit is overheated so it signals to inhibit the gas valve not to open. Since it is not opened, gas is not burnt through the manifold hence not heat why the machine is tumbling. Good luck.
Hello, your problem is going to be the flame sensor, this is located on the side of the tube where the flames are. if you have an ohms meter check it for condinity..you should find you don't get any reading on your meter, this will tell you it's bad..you should replace it. If you have any other questions or concerns please feel free to comment again. Good Luck!!! Mike
The most likely cause is a bad ignitor part number 279311. It has to glow to open the valve and ignite the gas. You should hear a loud click when you first start the dryer. That tells us there is voltage to the gas valve.
