    thank you for responding.

    i had a service tech come out and that is what he said.where is the thermal fuse located at in the dryer?

    what it did before it finally quit is, it would work properly for

    about 4-5 loads then no heat. on the display panel it would say "sensing" the dryer would keep running but no heat.

    also, is this something i can myself..i.e.thermal fuse or blower motor?

    thanks again

  • mylilsaab Jun 16, 2008

    thanks again,

    the drum does turn....but no heat...so..would i be better off taking the back off the dryer and seeing if the wheel is broken? and yes saving some dollars is a must.

    i do have the diagram printed out.

    thanks for your help

  • mylilsaab Jun 17, 2008

    back again, it is a gas dryer...no air flow coming out of the vent...before when the dryer was working properly you could hear the igniter light up.....now nothing. drum does turn..but no air flow.

    thanks again

  • mylilsaab Jun 17, 2008

    i can do that....there is a round cap on the side of the dryer on the bottom near the gas line...not sure if that will let me see if the ignitor is lite up...if not i will have to take the back off....a faulty igniter makes sense



    thanks

  • mylilsaab Jun 18, 2008

    ok i had to take off the front panel of the dryer to see the igniter along with taking of the top part with the controls. help me here as to how to check the igniter with the dryer apart..i dont want to blow up.

  • mylilsaab Jun 18, 2008

    ok i ran the dryer with the front panel off and the igniter did not light up..i ran it for ten minutes...could anything else cause this not to work properly?

  • mylilsaab Jun 20, 2008

    ok back again, i replaced the igniter and still nothing...the model number is DPGT750GC



    gas dryer.....

  • mylilsaab Jul 04, 2008

    after two weeks of finding time to replace the blower motor and the ignitor. i put most of it back together and did aa test run and nothing....the control panel does not light up..the light on the door does work .i check the circuit breaker. it has power.

    frustrated.

  • mylilsaab Jul 04, 2008

    ok i am back once again,,,i replaced the blower motor and the ignitor...the flame comes on for about ten seconds and then shuts off...is this common or is it suppose to stay on longer to get the inside of the dryer warm?

  • mylilsaab Jul 04, 2008

    i ran the dryer for 30 minutes..the ignitor would light up and the gas would come on for 2 seconds(the flame)..it should stay longer ....i have the front panel off and actually see it come on..i think i am just spinning my wheels into something that is a money pit....

    I'm not trying to second guess a tech that has already
    diagnosed this problem, but it just doesn't make sense to me. If the blower motor
    isn't working, the drum would not be rotating. The blower motor is also the main drive motor and it is used to drive the belt that spins the drum. The symptom that you would
    get is a dryer that just would not start, but the heating circuit may still function. Basically, a hot dryer that doesn't rotate. Normally a problem associated
    with a dryer that runs, but does not heat, is a heating circuit problem or the
    blower fan has broken off the drive shaft. The blower motor lists for about $216 at searspartsdirect.com, while the blower wheel only lists for about $63. That's why I asked the question in order for you to make sure you aren't spending money on any unnecessary parts. You need to double check the symptoms see if the drum is actually turning. Refer to the website I mentioned and type in your complete model number. Look under the "Drum Motor and Blower" heading to see what I am talking about. The drive motor is item number 450. The blower wheel is item number 481. Let me know what you find.

    Are you sure its the blower motor? A blown thermal fuse will cause the same symptoms.

On this dryer the blower motor and drive motor are seperate motors. If the blower motor is not running there will be no activation of the gas ignitor circuit. Probably it is the blower motor but could be in the electronics module.

Okay, I think we need to back up a bit here. I need to know, first, if the dryer ignites. This is a GAS dryer, correct? I need to know if the igniter is glowing, and if you can hear the gas start flowing when you have ignition. If not, this could be a simple igniter or gas coil problem. If there is ignition and the drum is turning, do you have air flow coming out of the dryer vent exhaust? If there is air flow, you cannot possibly have a blower wheel problem. We need to rule out some possibilities before we start disassembling the dryer. I'm a bit miffed as to why someone would tell you that the motor was the problem. Since I was not there, I need to know as many symptoms that you can provide, so I can give you with a correct assessment.

    If the igniter does not function, you will not get any gas flow. That may be why you aren't hearing any gas flow. In order for gas flow and ignition to occur, the igniter must reach a certain current potential before the gas safety valve will open. My guess is that you have an igniter problem. Can you please let me know if you can access the igniter and see if it is glowing? It will be located under the dryer drum.



    PS Keep in mind, a glowing igniter STILL does not neccessarily mean it is good. A weak igniter will cause the same problem.

  • Jeff Rockwell
    Jeff Rockwell Jun 18, 2008

    Replace your igniter if it is not glowing. In order for the dryer to ignite, the igniter should come on and begin to glow. It takes 30-90 seconds (depending on the age of the igniter) for the proper current potential to be reached. The gas valve opens, you hear gas flow and "phooom!", you have ignition. I tried looking up the pat using the model number you have this question posted under, but found nothing. Double check your model and number again, please. It will be located around the door opening, or on the back of the control panel.

    I found your model number listed at repairclinic.com. It lists a thermistor, but I do not have a wiring diagram to look at. I looked for a tech sheet, but couldn't find one, either. A thermistor acts much like a fuse. I would also be suspicious of the control board too, but (again) I do not have a schematic to see how this dryer is configured. There should be a wiring diagram under the control panel, along with troubleshooting advice. I'm sorry I have led you on a lengthy trail here, but it is difficult to make assessments without actually seeing the appliance. Normally, a burner assembly also has safety coils too, but I don't think this would fail to provide power to the igniter, and I did not see this part listed anywhere. So...I'm afraid I'm leading you on a wild goose chase here. If you can refer to any technical documentation or provide me with a wiring diagram, I may be able to assist you further.

    Thank you "papabutler", for your input. I did not know there was a separate motor. I could not find any drawings with this information. I'm sorry I have led "mylilsaab" in circles here.

  • Jeff Rockwell
    Jeff Rockwell Jul 04, 2008

    Mylilsaab,

    I don't know if you want any more feedback from me since I led you in circles the first time. From my experience with gas dryers, the flame is not continuous. The dryer will ignite and heat and periodically re-ignite as the dryer cools and reheats. 10 seconds seems like a short time interval, though. Have you tried lettting it run for a while to see if the dryer stays warm and cycles? The only other item that can cause ignition problems that I know of are the gas valve coils. Most gas dryers have two of them and they are often sold as a set. It is recommended that you replace both at the same time. I'm not telling you to buy more parts. Test the dryer, first. And, again I do apologize for all the troubles you've had. I hope something goes right for you.

GE Profile Harmony Gas Dryer not heating/drying clothes.


let me ask you this does the ignitor glow orange but no flame when you have no heat?usually on a gas dryer if at first you have heat and then after 10 to 30 minutes no heat it's usually the gas coils located on top of the gas valve,common problem,after the coils cool down they will work again,that dryer is kind of complicated to work on seeing how it does have two motors in it but you should be able to get at the gas coils,if you send the model number i can look it up for you.but it sounds like you have bad gas coils,the only way to tell is run the dryer,when the heat stops working look at the ignitor,if it glows orange and the flame doesn't ignite you have bad gas coils.

Dryer functioning but air not getting hot. this is a Maytag gas dryer


Hi,
Things that could stop a gas dryer from heating:
Glow bar igniter, thermal fuse (not all models), coils on the gas valve, gas valve, thermostats, motor heat switch, timer, selector switch, sensor.
On the back of the dryer near the fan blower housing is a thermal fuse, if this opens up (no continuity) the gas burner often quits but the motor will still run. If the thermal fuse is open/bad, always clean, change, adjust the venting system and vent hood first and clean out the dryer’s air ducts. Sometimes it is a good idea to replace the operating thermostat at the same time.
Thermal fuse parts help link...on blower housing cover, cannot be re-set, must be replaced if is open (no continuity between pins).
Thank you for contacting Fixya.com

No heat blower motor no working


The only sure way is to connect a good motor and see if it runs. In the last year I have replaced a few of those motors and no control boards. All the tests are electrical and the normal failure for that motor is mechanical.
