Gas Dryer does not continue to heat.

did you clean the vent line?THAT COULD MAKE IT RUN HOT THE AIR CAN'T BLOW OUTSIDE,BUT WITH THE DRYER HAVING HEAT WHEN IT STARTS AND THEN AFTER LIKE 10 MINUTES NO HEAT IT SOUNDS LIKE YOU HAVE BAD GAS COILS,WHEN THE COILS ARE STARTING TO FAIL THEY WILL WORK FOR LIKE THE FIRST 10 TO 20 MINUTES AND WHEN THEY HEAT UP NO GAS,WHEN THE COOL THEY WILL WORK AGAIN,I WOULD CHANGE THE COILS AND CLEAN OUT THE DRYER AND VENT LINE,THIS SHOULD BE DONE ONCE A YEAR SO YOU DON'T HAVE A FIRE AND YOUR CLOTHES WILL DRY ON TIME,EVERYONE THINKS SOMETHING IS WRONG WITH THE DRYER AND ALL THAT HAPPENS IS THE VENT LINE AND THE DUCT WHERE THE LINT FILTER SLIDES INTO FILLS WITH LINT AND THE AIR CAN'T BLOW AROUND GOOD ANYMORE,ALSO WITH A SHOP VAC VAC UP THE LINT WHERE THE BURNER AND MOTOR IS AND THEN SET THE VAC UP TO BLOW AND BLOW THE MOTOR AND GAS BURNER OUT,DO THIS AND YOU'LL HARDLY HAVE ANY PROBLEMS WITH THE DRYER

Hello there and welcome to fixya there are several things that could make this dryer not heat up
Here are the most common things

Thermal Fuse

If the dryer doesn\'t heat, but the drum
turns, check the thermal fuse(s). The thermal fuse protects the dryer
from overheating and helps to prevent fires. If the thermal fuse is
blown, it will have to be replaced.

Gas Valve Solenoid

The gas valve has two or more electric
solenoids which open the valve to let the gas flow into the burner
assembly. If the dryer doesn\'t heat one or more of the solenoids may be
defective. If the igniter glows for 90 seconds but the burner flame
doesn\'t light, replace these coils as a set.


Dryer Igniter


If the dryer doesn\'t heat, the igniter might
be burned out. Check the igniter for continuity with an ohm meter. Dryer
igniters burn out over time, similar to a light bulb.

Heating Element

The heating element on an electric dryer can
burn out over time. If the dryer doesn\'t heat, the element should be
checked for continuity. The heating element cannot be repaired and must
be replaced if defective.

Heating Element Assembly

the heating element assembly on an electric
dryer can burn out over time. If the dryer doesn\'t heat, the element
assembly should be checked for continuity. The heating element assembly
cannot be repaired and must be replaced if defective.

Flame Sensor



Gas dryers have a flame sensor to detect the
heat given off by the flame. If the dryer doesn\'t heat, the flame sensor
might be defective. Check the flame sensor for continuity. This is not
as common as a burned out igniter or thermal fuse.


High Limit Thermostat


Although not common, if the dryer doesn\'t
heat the high limit thermostat can be defective. It can be checked for
continuity. If the thermostat is "open" the dryer doesn\'t heat.


Cycling Thermostat




The cycling thermostat regulates the
temperature of the air in the dryer. If the dryer doesn\'t heat it may be
caused by a defective cycling thermostat. This is not common.


Main Control Board

The main control board is normally not at
fault when the dryer doesn\'t heat. Check all of the other components in
this troubleshooting guide before replacing the main control board. The
main control board cannot be tested easily and must be replaced if it is
defective.


Timer
The timer is normally not at fault if the
dryer doesn\'t heat. In many situations where timers are replaced they
end up being returned. Check all of the more common components in this
troubleshooting guide before replacing the timer

check all the thermal fuses with an ohm meter if one of then is not showing any continuity the replace it this should help good luck

Hi, very common problem.

The problem is with the gas coils.
When they get weak, they only come on for about 10 minutes and then the machine will blow cold air. There are 2 of them with one being the booster coil. They come in a pair and run less than $20.

Best of luck. Please e-mail me if you have any other questions.

Check for a blown thermal fuse or a faulty heating element. Both components can be tested using a multimeter or ohmmeter. Check for continuity. A lack of continuity indicates a faulty component. The thermal fuse is about an inch long and is located just inside the rear of the dryer and is usually attached to or near the exhaust duct. Hope this helped and best wishes.

Could be a bad hi limit thermostat. Could be a bad glowbar ignitor. Check the glowbar ignitor at the gas valve, is it glowing bright orange/red? If not. Replace the ignitor.

Did the fuse blow out? If so then the heating element is shorted out. This happens frequently when they fail. If the fuse is blown check the condition of or change out the heating element.

i am sending you all the possibilities for your problem, check either of these causes ----and than let me know if it is solved----

Power from the house
Check to see whether there's power getting to the dryer. Is it plugged in? Check for blown fuses or tripped circuit breakers--your dryer uses two fuses or circuit breakers. The dryer could tumble but not heat if only one of the two fuses is blown. If you have circuit breakers, one of the two circuit breakers can trip, even if the two for the dryer are connected.


Heating element
Often a dryer heating element burns out, but doesn't trip the circuit breaker or blow a fuse. The heating element is simply a long coil of special wire. You can check it for continuity with an ohm meter. No continuity means the element is bad and you need to replace it--electric heating elements aren't repairable.


Thermal fuse
On many dryers, there's a thermal fuse mounted to the exhaust duct inside the back cover panel. The fuse--which is about an inch long--is usually embedded in black resin and mounted in a white plastic housing. If the fuse has blown, you need to replace it. (You can't re-set it.)


Wiring
A common problem is for the main wiring connection from the house, at the dryer, to burn and break its connection. Because the dryer can still tumble with partial power, the connection may be only partially defective. You may need to replace both the power cord to the dryer and the terminal block inside the dryer that the wire is attached to.

I have the same exact problem. Dryer works great....when empty. Put wet clothes in and 3 or 4 hours later they are as wet as when I started. I am going to kick the piece of junk to the curb and go get a GE dryer right now.....I suggest you do the same.
