How a burner works:
When the motor begins to turn, the motor switch closes allowing a current to reach the flame sensor. The flame sensor allows electricity to reach the igniter. The igniter then heats up to a temperature high enough to ignite the gas. Once the igniter is hot enough the flame sensor releases the igniter circuit which allows the current to run through the coils that open the gas valve. Gas then releases out past the igniter and lites fire and the heat is drawn into the dryer.



How to troubleshoot: Observation is key to troubleshooting a gas dryer.

If your dryer is hot at the beginning of the cycle but finishes cool then it is likely you have bad solenoid coils on the gas valve itself. As the coils age, they lose the ability to keep the gas valves open. This will sometimes cause the valves to open and close rapidly, resulting in a chattering sound. Unfortunately, the coils can’t be tested to verify the failure so replacing them is a decision based on the above.

Holding coil term 1 and 2, 1365 ohms ±25 ohms.
Booster coil term 1 and 3, 560 ohms ±25 ohms.
Secondary coil term 4 and 5, 1220 ohms ±25 ohms.


If the dryer never gets hot, there are more items to check and test. The first item is the Igniter. There is a clear plastic connector attaching the igniter to the burner. Disconnect this and place your probes onto the two contacts of the igniter. The meter should read under 100 Ohms of resistance. Any reading above this means that the igniter needs replacing.


If the igniter passes the test then you need to test continuity on the flame sensor. You should have continuity between the two contacts. If not, then you need to replace the flame sensor.

There are thermal fuses and cutoffs that will open if the dryer gets overheated. These will not allow the dryer to heat if they have an open circuit.

This manual will explain how to diagnose and correct burner problems in most dryers, ranges and ovens. Learn how the burner is supposed to work in order to find your problem faster.

Hi,
I have a Kenmore 11072702101 that won't heat. If I have ruled out the ignitor, then I can move on to check the flame sensor, but I can't find that part on the exploded view of the burner assembly or the bulkhead, is it called a radiant sensor? I found a part with that description. Anyway if you can help me out I would greatly appreciate it. Thanks

Radiant sensor=flame sensor

Using the OHM meter, the 2 contacts on the radiant sensor must show continuity. (0 Ohms.)



Don't forget the thermal fuses in back must all show continuity.
