Question about Dryers
The dryer runs, the sensor turns bright orange, but i never hear a clicking noise and there is no igniting of the gas. Any ideas? Do i need to replace the coils?
SOURCE: no heat
You may have a weak igniter. Just because the igniter glows, does not mean it is working properly. The glow bar type igniters are supposed to draw a certain amount of current in order for the gas valve to open. If the current potential is never met, the gas valve will not open. This is a safety feature used to prevent gas flow without ignition. The current readings for the igniters are as follows: Round style glow bar: 2.7 to 3.2 amps Square style glow bar: 3.2 to 3.7 amps If it is reading less than the required amperage, replace it. This may just solve your problem. Let me know if this helps you.

Is yours the gas model? If so I need you to look for some things. Open back door panel and see if while trying to light the igniter is glowing orange. Sea Breeze

The thermal fuse is easy to test. Just check continuity using a multimeter or ohmmeter. A lack of continuity means a blown thermal fuse.
The coils are difficult to test. You can use a multimeter or ohmmeter and check for continuity, but the problem is that a coil may be sticking open only after heating up, so you can see the difficulty this would present. If a coil is suspected of being faulty, it is best to replace both (all) at the same time. These coils are what permit the gas valves to open and they can cause a no light or a cycling condition. Really sorry for your trouble and I hope this helped. Best wishes.

check the thermal fuse in the dryer vent duct to be open,then if not the flame eye" radiant sensor" or the high-limit thermostat both on the burner tube if the sensor doesn't see(sense) a flame the gas valve will stay shut,then check the gas valve coils,both the BOOST and SECONDARY coil valves on the gas valve body as these can open up and not gas into the burner

Their is a flame sensor, an ignitor, and a pair of coils all wired together into one assembly.
Here is the heat control and duct fuse:
Check that fuse next to that control. If it is open the dryer gas assembly won't get any power.

From the description you give the most likely cause of this problem are bad gas coils or a bad gas valve.
You say you see the flames for 10 minutes before it stops heating but you don't mention if the igniter is continuing to glow. One thing we need to know is if the igniter continues to cycle on and off when the dryer stops heating.
There is a small square plug on the front panel you can remove to try and visually check if the igniter is glowing.
The problem won't be the thermal fuse or one of the thermostats. Once the fuse is open the dryer won't heat but it won't start to heat after 20 minutes.
After the dryer runs ten minutes and stops heating then check if the igniter is still cycling on and off. This is important because if the igniter is working then the thermostats and igniter are okay.
When the igniter glows at some point you might hear a click and the igniter would stop glowing. The click is from the flame sensor and after the click and the voltage is removed from the igniter at the same instant the voltage is applied to the gas coils and you should get a flame.
You might hear a hum, buzz or vibration from the coils when this happens. If the coils seem to react to the voltage but there is no flame then most likely the gas valve is bad. If the coils don't do anything then most likely the coils are the problem. The gas valve and gas coils can work for 10-15 minutes and then heat up and stop working till everything cools down.
One other thing I must tell you about the gas coils. Here is a link to the gas coils you will need. These are the new style that will last quite a bit longer the the older one. The coils are like the spark plugs in your car. The will need replacing in time due to wear. Below is a video to walk you thru the repair process.
