See if there is something blocking the vent. This will cause it not to heat. Are you sure the gas orifices are clean and moreover, is the gas pilot on.

Dryer is not blowing heat


ELECTRIC Dryer no heat or little heat:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.

Gas dryer 11076832500 no heat


ELECTRIC Dryer no heat or little heat, or shuts down to fast:

Check your venting and lint basket. Check blower for lint build up and blower wheel obstruction., test by trying to turn the wheel manually by hand (should be easy) May have to remove cabinet or front/back plate to get to it)

Next check the heating element itself with a meter for continuity OHMS CLOSED CIRCUIT. If not its defective or has a short if its grounding out? Which in turns causes blown fuses or thermostats or overheating.

Check dryer Terminal block prongs both outside prongs should give combined 220, and 110 each if u check 1 outside & 1 center (ground) prong. Also check house electrical outlet for full voltage. 220 because if u only get half or 110 volts you will be able to run the machine which uses only 110 to run motor but not the heater which uses a full 220,

Check the thermal cut off, the cycling and the hi limit thermostats.
For continuity or OHMS. If no ohms or resistance they need replacement.

In some dryer's the control panel relies on a thermistor rather than a CYCLING thermostat to regulate the drum's air temperature by monitoring the component's resistance changes; resistance goes down as temperature increases and up when temperature decreases. Once the drum's air temperature reaches a certain level required to dry clothes, the control panel shuts off the heater. The panel will turn the heater on again and begin another heating cycle when the thermistor indicates that more heat is needed to keep the air temperature constant inside the drum

Lastly check your moister sensor. ( located inside the dryer door usually) Especially if machine seems to shut down early and clothes are still wet.
Test with a meter at room temperature and it should show continuity.
A failed moisture sensor will affect the dryer run time in the automatic moisture sensing cycle but it will not affect the heating of the dryer or the timed cycle. Which are reflected by the thermostats.

Gas dryer, runs fine for maybe 10 minutes than the heat goes off and doesn't come back on...change the thermal kit and no fix


Hello,
The reason your gas heated dryer starts off heating ok,but a part way through the cycle it is no longer heating as it did when it started,is beacuse the coils that open the gas valve are getting hot and breaking down when they are warm. At start up of cycle the coils are cool,but when the dryer heats up as it runs the coils that are weak can not handle the heat and do not open the gas valve. Replacing the gas valve coils with fresh,strong ones will open the gas valve the entire duration of the drying cycle. All appliance manufactures use the same exact gas valve coils and label them with their unique part number. Having been in the service business i know they are all the same and the part number for the least expensive gas valve coils is 279834
They can be purchased at your local appliance parts store on online at
searspartsdirect.com
repairclinic.com
apwagner.com
apdepot.com
midwestapplianceparts.com

To replace the coils,remove bracket over them(dont worry about where it says dont grip thats for when dryer is plugged in) unplug them and install new ones,that bracket has notches in it and the coils have tabs that inter lock so they position them self exactly where they fit.

This is what the coils looks like

Dry will not blow heat


Check the entire exhaust vent tubing before buying anything for this dryer to repair.. Most dryers only need a good cleaning to get the heat back running correctly. A moister sensor is working if the lint build up is more than just dust in the vents tubes. Any build up the sensor detects and keeps the heat off. Sometrime you will get heat for awhile although it will shut the burner down quit soon

My dryer is not getting my clothing dry. what could be the issue of not drying my clothing?


Blocked air vent. Check where the vent exits to the outside, as usually condensation builds up on the "bird blocker" which attracts dust, which attracts condensation, which attracts dust... etc.

Gas valve coils. The gas valve is opened by two electromagnetic coils. When they start go go bad, they will open the gas valve in the beginning of the cycle, then as the current heats them up, they will quit working, and you will lose heat partway through the cycle.

Igniter. The gas is lit by an electrical lighter similar to the cigarette lighters cars used to have. If the igniter breaks, then the gas valve coils don't turn on, and you get no heat at all.

Dryer is slow dryng takes two cycles compared to regular dryer


As the model number you provided indicates this is a gas dryer, you need to open up the access panel, above the washer compartment, to clean out the dryer compartment.

It is likely that either the gas burner components have been covered in lint and dust and are getting shut off sooner than they should because of overheating of the thermocouple safety device, etc.

First, make sure that the power is turned off to the washer/dryer unit and turn off the gas supply valve, so you don't have any issues with getting a electric shock or getting a gas leak/build up.

Once you've done that, you can remove the two (2) access screws that will let you get into the lower dryer compartment where the gas burner and control devices are located (this is the panel just above the washer lid, the angled section).

Now vaccum out all the lint and dust buildup you can see and check that everything is free of dust and lint inside this area. Pay special attention to the gas burner and gas inlet orifices, as anything in there can and will cause the dryer to shut off and thus, not operate properly in getting your clothes dry in a normal drying cycle.

Also, check to see that the dryness sensors inside the dryer drum (silver bars up near the top left or right of the dryer drum) are clean and don't have any residue or buildup on them. This can also cause the dryer to register erraticly when using the automatic drying cycles versus the timed drying cycle. Use a good glass cleaner and wipe these sensors with a clean cloth rubbing them briskly to remove any residue or contaminent that might be deposited on the sensors.

Now completely clean out the exhaust vent all the way from the dryer to the outside location of the vent. Having any blockage of the vent can and will cause the thermal overload protective device to function and turn off the gas burner that provides the heat to dry your clothes. So be absolutely certain that the entire vent exhaust is clean and free of any lint buildup from the dryer all the way to the outside vent (yes I mean't to repeat that!) You'll have to remove the outside vent grate/cover to check for any buildup/obstructions there.

Now you can run a load to see if you've gotten the problem solved, if not, it could be a control module, but 80% of the time, it is nothing more than a "housekeeping" issue that causes loads not to completely dry on the first cycle. So please do some cleaning and checking and you should be back getting your clothes dry on the first cycle!

Hope you find this Very Helpful and best regards!
