Kenmore Gas Dryer Runs but Does not Heat. Thermal Fuse is OK

I have a Kenmore Gas Dryer, model # 110.97572120 I have it fully taken apart and have checked the thermal fuse. It is OK (at least I think it is.... the black strip connecting the two metal prongs is still intact). I don't want to just be guessing at what part/s I might need to fix. Any help is greatly appreciated. Thank you!

For Ordonte: The thermal fuse is described in the video that I provided below. On a gas dryer, it will prevent the unit from heating if it is blown. The first image below shows the location of that fuse if you have the type of Kenmore dryer with a lint screen that pulls out of the top panel. That fuse is also shown in the photograph that Jason provided above. It is the one with the red and blue wire attached to it. If you have a dryer with the lint screen that pulls out of a housing just inside the opening to the drum, then you can usually refer to the second image to find the thermal fuse. There are many different models of Kenmore dryers. If your dryer is different than the ones shown below, reply with the full model number. Once you locate the fuse, check it as shown in the video below. If it is blown, you can order a replacement fuse from the Sears PartsDirect.com website. Be sure that you clean your exhaust vent duct system as shown in the video below if that fuse was blown. If you need more help, reply with additional details (and that model number).

According to your photographs, it looks like the wires are attached properly. I compared your connections to the wiring diagram (even though it is difficult to read). The wires appear to be connected properly according to that diagram. I recommend that you reassemble the dryer and see if it runs and heats properly. If you have any problems, unplug the dryer and reply with additional details.

Thank you so much Lyle.... It turns out my thermal fuse was bad. I know have another issue. The problem would have been easy to fix in the first place, but I made it difficult on myself by tearing the whole thing apart. Now I'm not sure if I have two pieces wired back in correctly. I have uploaded images. Thank you.

Visual inspection of the thermal fuse in this dryer will not normally indicate that it is good. Here is a link for a Repair Clinic.com video that shows how to check that component using a volt/ohm meter:

Thermal Fuse Testing

. You can also tape the wires together that go to the thermal fuse (with the dryer still unplugged) to bypass it. Reassemble the dryer and see if the dryer will heat with this fuse bypassed. (Be sure that you open the gas supply shut-off valve.) If it does then replacing the thermal fuse will fix your dryer heating problem. You can order a thermal fuse (part number 3392519) from the

Sears PartsDirect

website. NOTE: Check the exhaust vent duct system for a clog or restriction as recommended in the above video if the thermal fuse was blown. Also, do not continue to run the dryer with this fuse bypassed. It is an important safety component that must be replaced to operate the dryer.

If the thermal fuse is okay, you could have a problem with one of the thermostats in the dryer circuit. I provided a wiring diagram for your dryer in the image below. The heating circuit is traced in red. This wiring diagram shows that the operating thermostat or the high limit thermostat could also prevent the dryer from heating. I recommend that you check those components the same way that the thermal fuse was tested.

If those components are okay, you could have a problem with the gas valve assembly. The theory of operation for the gas valve assembly is shown in the second image below. I recommend that you reassemble the dryer and pull the observation plug in the lower front panel of the dryer. Make sure that you open the gas supply cut-off valve. Start the dryer in a heated cycle and see if the igniter glows to begin the ignition process. If the igniter glows and then fades out to light the burner but it does not ignite, then you could have bad gas valve coils (kit part 279834).

The timer not running in the auto cycle is not unusual since the dryer is not heating. See if the timer advances in the timed cycle. If it does, then that component is likely okay.

These tips should help you properly diagnose and repair your dryer. If you need more assistance, reply with additional details.

If you do not feel confident repairing this problem yourself, then you can have it repaired at your home by a Sears technician. Here is a link for the website:

Dryer diagnosis can keep you guessing. I located a previous expert post with some additional things you may check. The model is a bit different, but may help while you wait for the expert to review your model. I attached the link below. Hope this helps!

I should also add that the dryer turns on fine, but the timer does not work. I'm not sure if that could be affecting a setting of heat / no heat? Just one more piece of information.... Thank you!
