The dryer was working great until a week ago.  It is doing the exact same thing.  The burner only stays on for like 8 seconds.  Is there any reason the coils would go bad in only 8 months?  Could something be causing it.

It might be an air flow problem, them dryers are notorious for a stripped out blower wheel causing incorrect air flow conditions

How can I check for a stripped out blower wheel.  How do you get to the blower.  What's the easiest way without taking too much apart.

You gotta break it down to clean it out. This is a newer model and I have not worked on one but most of these newer ones have to remove some screws on the back side and slide the top off and then the front can come off from there the dryer is exactly like that of a DOT dryer with the removable filter bladder and heater element to the right hand side on the bottom and the blower wheel to the left on the bottom.

I have it apart right now.  The blower wheel looks ok.  When you spin it the drum turns.  The airflow coming out the exhaust  when it was together seemed pretty good.

Everything looks fine there.  Nothing broken, cracked.

Maybe you need to change the coils or check the connections or both.

I changed the coils 6 months ago.  Worked fine for 6 months.  I just changed the coils tonight and still the same problem.

A Samsung built dryer.

If the dryer vent from the rear of the dryer to the outside vent hood of the home is absolutely/positively clear & not obstructed--replace this thermostat on the burner housing...

I even tried running the dryer with the exhaust vent disconnected and just blowing into the room and still taking hours to dry.  The air flow coming out seems pretty strong.

Other possible causes of erratic gas flame function:

1) Main Board (faulty relay)

2) Failing Centrifugal switch on the motor/burnt contacts (New Motor needed)

3) Failed Flame Sensor (intermittent function/burnt contacts)

4) Failing Thermistor (Ohms too low at room temperature)

This can be a *very* difficult fault to diagnose.
On some Samsung dryers that I've serviced---if the symptom was:

"Poor Heating/Long Time To Dry"

or

"Igniter Glows-but-No Flame"

(The exhaust vent system is checked & okay and the gas valve coils were verified to be good)

Test Thermistor ohms at room temperature (listed as 77F) Located on blower housing.

I check the voltage from the Main Board-to-the-Gas-Valve-Coils (115 volts)

Test the Flame Sensor Switch (ohm & voltage)

Test the motor Centrifugal Switch (ohm & voltage)

In most cases--the relay on the Main Board was either erratic or failed to send voltage to the gas valve coils.

This dryer is a bit technical for the average DIYer. It may be wise to contact an authorized Samsung Service Center in your area for an out-of-warranty repair. A zip code service locator is available on Samsung's website (click "Support" first):
