Kenmore gas dryer #41793142300 electronic start doesnt heat up


if you first have heat and then like 10 to 20 minutes later no heat you could have bad gas coils,on most gas dryers there's a plastic cap you can pop off on the front panel so you can look in and see the ignitor,if at first the ignitor glows orange and the flame lights then after a few minutes the ignitor glows orange and the flame doesn't light you have bad gas coils,they are located on the top of the gas valve,easy to change.part number 5303931775 go here and look at part 71

My dryer has been working fine until recently. It is not heating up throughout cycles. Is there a pilot light that should be checked? If so, where?

GE Gas Dryer Model #dbvh512gfoww heat problems


Hi, It sounds like the coils on top the gas valve are bad. If the ignitor glows but shuts off before a flame, the coils need changed.
I hope this helps. If I can assist you further, please let me know.

Thanks

No Heat


Hello
Welcome to Fixya


Remove the vent line from the rear and try the dryer.
If it heats then that means there is a clog or kink in the vent line blocking the vent air from exiting which will stop the dryer from getting hot!
If not then it's another one of these problems.

Defective Ignitor (Gas Only)
When heated the ignitor used on your gas dryer must obtain a specific high temperature
in order to activate the flame sensor. This ignitor is fragile and susceptible to cracking.
A hairline fracture that is barely visible to the naked eye is enough to change
the resistance of the ignitor to a point that is will not work properly.
You can test the resistance of your ignitor. You should get a reading of 50-400 ohms of
resistance.

If the ignitor gets hot and then goes off after about 10-15 seconds and there is
no ignition, the problem is probably not the ignitor. It is most likely the gas valve
coils that are defective.

If the ignitor comes on and stays on, it is the flame sensor that is defective.

If the ignitor is not getting hot it could also be one of the thermostats that is defective.
The power for the ignitor is passed from the timer, through all of the thermostats,
limit switches and fuses to the ignitor. So if you are not getting power to the ignitor
during ignition, you should check the continuity of the individual thermostats and fuses.
DRYER DOES NOT HEAT



Defective Gas Valve Coil (Gas Dryer Only)

If the gas dryer will light once but will not relight until it cools down, it is likely the gas valve coils are faulty. These coils loose some strength when subjected to heat. When they become old, the addition of heat may be enough to prevent them from opening the gas valve when hot. However the coils still work when when cool.

An easy way to diagnose the coils when the burner is not lighting, watch the ignitor. If the the ignitor glows for 10 to 15 seconds but no flame is created, then the coils are faulty. If the ignitor is not glowing the problem is elsewhere.

Recent Customer Symptoms:
The dryer burner doesn't always come on when starting. If the burner does come on, once it goes off if won't come on again until the dryer cools down.



Defective Flame Sensor (Gas Dryer Only)
The flame sensor's job is to monitor the ignitor for sufficient heat
to ignite the gas. A properly operating flame sensor will pass a
continuity check under room temperature.

Common Symptoms
If the flame sensor is defective in the open position,
the ignitor will not get hot when the dryer is started.
However, if it is defective in the closed position the ignitor
will get hot, but the flame sensor will not allow the flame to ignite.
In this case, the ignitor will usually stay hot for a long period of
time.



Defective Thermostat
The thermostats are responsible for maintaining the proper temperature
in the dryer. Check the exhaust temperature of the dyer and if the
temperature is above 150 degrees, you will most likely need to change
the operating thermostat.

The thermostat can also fail in the opposite mode.
It can prevent the element from heating at all.
A failed continuity check at room temperature will verify this condition.

There are some special thermostats that are single pole double throw.
These thermostats are often used to control the timer when set to the
Automatic Dry cycle. If the dryer timer will advance in the Timed Dry
cycle but not the Automatic Dry cycle, then the thermostat could be the
problem.


Defective Thermal Fuse
The thermal fuse is in series with one leg of power to the motor.
If the fuse is open (no continuity) the motor will not run.

Location:
The thermal fuse is located in different locations according
to the model and brand of dryer.

Solution:
Check the thermal fuse for continuity with a volt/ohm meter.
If it is open, it will need to be replaced

No heat from Kenmore 110.74642400 model.


Replace the coil packs on the gas valve this fixes 90% of gas dryers lighting intermittently. Of course first thing to verify is gas supply. Dont forget to rate my solution as solved if I accurately answered your question...Thanks!!
