    its a gas dryer, yes sometimes the heat will work like it should and sometimes its only cool air when it should be heated.



    thanks

    Is this gas or electric? Then you say "most of the time" so, it does work fine some of the time?

Since it works sometimes my first thought is the solenoids.

The gas valve is turned on and off by these solenoids but you will need an OHM meter to check them and even then it can be missed. The OHM meter checks for continuity, to see if there is a break somewhere inside the solenoid coil and if the dryer works "sometimes" this break must be making contact "sometimes". Two wires go to the solenoid so, when the two leads from the meter are connected to these wires then it might show that it is good until you start moving these two wires around.

Hope this helps.

My whirlpool dryer comes on and runs good but it wont get hot can you tell me whats the problem


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.

Help me find my model number


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

Barrel isn't turning.


I believe you will find the belt is broken.
There is a motor which is supposed to turn a belt, which in turn drives the drum.
If you wish to repair ir yourself, a letter to "Fixya" could cause someone to walk you through the steps.
Be blessed.

I have a GE DCVH660GH0BB gas dryer.That doesn't heat or sometimes heats for a short while then stops heating.


You will need to check the thermostats on the blower housing for continuity.

Dryer turns off after short period of time


It can be a lot of things. From the dryer elements getting to hot to the motor getting over heated. Try running it empty load to see if it shuts off. If it doesn't then it is the motor over heating.

Dryer wil not spin


Hope this info helps, ps don't forget to give me a rating thanks!!


For an electric dryer that runs but doesn’t heat, follow this repair roadmap:
Flip the circuit breaker off and then back on. Electric dryers run on a two-pole, 240v breaker. A common problem is for one of the legs to break which cuts the 240v that the elements need to heat up but it still supplies the 120v for the motor. The result is that the dryer runs but doesn’t heat.
If the breaker checks out, then it’s time to do some surgery. Unplug the dryer and open it up.
. Use your ohm meter to test the thermostats. All should show continuity.
Measure the resistance of the heating element with your ohm meter. Normal readings are in the neighborhood of 30 ohms.
In rare cases, the centrifugal switch in the motor can fail which breaks the power circuit for the heating elements. If this is the case, then the entire motor must be replaced since the centrifugal switch is built into the motor.
