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 a whirlpool gold gas dryer model#GGQ8858JT1. When I push the start button the dryer starts and spins but the heat does not come o


does the igniter glow? If not check for 110 volts at igniter .
Check for 110 volts at gas valve if no volts check hi limit thermostat , operating thermostat, safety switch on motor,
the coils on the valve & the timer contacts that feed the voltage to the burner.

Non Glowing Igniter


What solenoids are you referring to?

When you set the timer and heat selector switches on your dryer and press the button [switch] to turn it on, the direction of 120VAC passes through the heat selector switch through the timer switch through the cycling thermostat through the hi-limit switch, through the thermal cut-off fuse to the burner assembly's gas valve.

Simultaneously, as the current is traveling through a path to the 1st gas valve coil, current is also traveling through a path to the flame sensor- and then to the igniter.

The igniter will begin to glow and when it gets hot enough, the flame sensor will detect the heat and switch off. which then diverts current to the second gas valve coils.

The second gas valve coils activate plungers in the gas valve which allows gas to flow out into the burner housing. The igniter still being hot, ignites the gas to a long blue flame.

To maintain the proper air temperature, the heat in the blower housing is monitored by the cycling thermostat. During normal operation, air temperature should be between 120 degrees Fahrenheit and 160 degrees Fahrenheit.

When the air reaches the proper temperature specific to your dryer model, the cycling thermostat will switch off the voltage to the burner assembly.

The hi-limit thermostat and thermal cut-off fuse monitor the drum air temperature. If there is an air flow problem [restriction or total blockage], the hi-limit thermostat may switch off the voltage to prevent damage to the dryer.

Eventually, if the air flow problem [restriction or total blockage] is not corrected, the thermal cut-off fuse will fail (blow) and the dryer won't heat at all.

Check continuity to the following components, thermal cut-off fuse, hi-limit thermostat, igniter, flame sensor, and cycling thermostat. Of course you will take your readings with the power cord of the dryer unplugged from the wall outlet.

You will either disconnect [isolate] any of the wire leads going to their respective components during the test [using a multimeter (analog or digital)]; OR remove each of the components entirely from the dryer to test them.

1.) A good thermal cut-off fuse will have 0 Ohms of resistance. On the other hand, if the needle [on a an analog tester] does not move OR the digital display [on a digital meter] has not changed significantly, there is NO continuity - which means the fuse has burned out and needs to be replaced

2.) A dryer's Hi-Limit Thermostat is activated by hi-temperature changes (between 250 degrees Fahrenheit and 300 degrees Fahrenheit.

A good hi-limit thermostat will have 0 Ohms of resistance at room temperature.

To test the thermostat's response to temperature change, place the component on an electric griddle or skillet. Set the heat on the skillet or griddle to the appropriate temperature according to the temperature rating stamped on the hi-limit thermostat you are testing. If the hi-limit thermostat switches off within 5% of that temperature, the part is functioning properly. However, if the hi-limit thermostat does not switch off OR switches off prematurely, the hi-limit thermostat is faulty and will have to be replaced. [Remember, when the switch turns off at the appropriate temperature level- you should get a high resistance reading to show that the circuit is "open")

3.) Perform the same procedure as step 2 to test the Cycling Thermostat: First at room temperature and then its response to temperature change. The only difference is, the test temperature range will be somewhere between 120-160 degrees Fahrenheit Once again, refer to the temperature rating stamped on the component you are testing- and the 5% tolerance remains the same, too.

4.) The resistance reading for the igniter is between 50 and 400 Ohms of resistance; anything else, it's faulty- toss it and replace it.

5.) You should get a resistance reading of 0 Ohms at the flame sensor-

Flame sensors are tricky though. Flame sensors could still short out and
allow the igniter to glow- but would prevent voltage from reaching the gas coil. For example, the igniter will glow and not turn off and a flame will not be established because there was no voltage at the gas coil to open up and release gas for ignition.

Hope this info helps...I would appreciate a follow-up from you when you resolve this problem- to gain more knowledge and skill.

Thank-you and best wishes on your project

Hi, If you are having problems with your gas dryer not heatingthe most common problem is that the ignitor goes bad. Even though it glowssometimes it is still not working properly. if you dryer is gas check out this gas no heat tip.... If you have an electric dryer, you can have many differentthings that can go wrong causing the dryer not to heat. check outthis electric no heat tip...

Gas dryer runs but gas does not heat up. How do I know if it's a thermostat or something else?


it can be the ignitor bar or the flame sensor eye on the burner tube,the hi limit thermostat on the burner tube,the cycling switch/thermostat on the blower housing,the gas valve coils on the gas valve body all components can be checked with a multi-meter or ohm-meter

Starts up and runs but there is no heat ,have gas supply but burner does not fire ,looks like i ahve voltage to all componets except to the hi heat thermostat


check the thermal fuse in the dryer vent conduit near the exhaust vent,then the cycling and high-limit switches/thermostats,your radiant sensor on the burner tube,your glow coil that ignites the gas,and finally your boost and secondary solenoids on the gas valve for continuity

GE Gas Dryer DVL223GB1ww will only heat a little. Drum is ok, I opened it up and lint is not the problem. I get it to heat to maybe 120'F and that's it. Any body know what's wrong with the thing? Thanks!


Several possibilities. Operating thermostat cutting out early Cycling on the Hi Limit thermostat Burner coils dropping out and not allowing it to come up to temp. "Lint not the problem" I will assume it has been completely checked for blockage from the fan to the exit.....

The unit runs but no heat.


Your limit switch has tripped. You will find this small switch near the burner that is the size of a dime. Press the small button between the wires firmly to reset it.

No heat


Hi

First check and see if you have 110 volts coming to the gas valve at the connector. If you have voltage, then unplug the dryer and check the parts like coil.

If you do not have voltage coming to the burner, then you will need to check the timer contacts that feed the gas burner, hi limit thermostat, operating thermostats, the safety switch on the motor, and any other point.

Also check for a open circuit on one of the gas coils, replace them all = less problems later on. If the glow coil does not work ( get red ), check it with a ohm meter for continuity.

Please ask for further clarifications.

Please rate this solution as fixya if found useful.

Thanks

I HAVE A 13 YR OLD GE GAS DRYER THAT WILL NOT HEAT.


Look up a WE4X800 and get one. The fuse is mounted near the blower housing and monitors the heat. Most likely a blocked vent pipe blew it so clear the vent and change the fuse.If you get a pix of a WE4X800 then you can find that puppy on your dryer. If it is blown the dryer will run but there will be no power to the burner assembly.If you have more questions just comment on this answer and I will get back to you.
