I don't have a service manual for this model of dryer. I have technical information but it is on microfiche. I provided some images of that microfiche information below. The third image shows information about troubleshooting this heating failure in the dryer. I recommend that you check to see if that igniter is glowing on that gas valve assembly when the dryer is running in a heated cycle first. You should find an observation port on the lower left side of the front panel. Pull the plug in that port and run the dryer in a heated cycle. If that igniter is glowing and then fades out but the burner will not ignite, then you probably have a gas supply problem or failed coils on that gas burner assembly. The basic theory of operation for the gas valve assembly is shown in that link for a previous answer posted in the above response. Your gas valve assembly is slightly different than that one but the basic operation is the same. Check the gas supply that you have provided to the dryer. If that gas supply is okay, then you will probably need to replace the gas valve coils. The coils that you need for this dryer contained in kit part number 279058. You can order that kit from the Sears PartsDirect website. Unplug the dryer and shut off the gas supply before accessing and replacing those coils. You will normally be able to access the gas valve assembly by removing the bottom front service panel. If you need more help with accessing that component, reply with additional details and we will assist you further.

If the igniter is not glowing, you could have a bad igniter, a failed flame sensor (radiant sensor), a bad operating thermostat, a failed high-limit thermostat, a bad relay, a failed motor centrifugal switch or a wiring failure in that heating circuit. You may be able to use the troubleshooting information in that third image to diagnose this failure. You can unplug the dryer and check the continuity through the operating thermostat and high-limit thermostat. Remove the back panel to access those components. The location of those thermostats is shown in the first image.

I hope that this information helps. It will be a challenge to diagnose and repair this failure on your older dryer considering the limited technical data.

If you need more assistance, reply with additional details.

Q:

Can you give me instructions on how to replace the belt on Kenmore dryer model 110.77894600?

A:

The procedure for replacing the drive belt in this type of dryer is shown in the image below. Make sure that the dryer is unplugged and the gas is shut off when performing this procedure. The image below shows the routing of the belt through the idler pulley. This should be the information that you need to complete this repair.

NOTE: Your dryer will look slightly different than the one shown below but the basic procedure will be the same. You may already have the front panel off. If not, you will need to remove the bottom front service panel and release the door hinge springs before removing the upper front panel.

If you need more help, resubmit your question with additional details.
