I answered the earlier question that you submitted. That answer was based on model number 110.69422800 so it is valid for this actual model (110.69422801) as well. Here is a copy of that answer:
Check the house circuit breaker for the dryer to make sure that it is not tripped.
On this type of dryer, the door switch could be bad or you could have a blown thermal fuse that would prevent the dryer from running. Less frequent possibilities for failures include a bad timer, a failed push-to-start switch, a wiring failure or a bad drive motor.
Check to see if the drum light turns off when you push the door switch in to simulate the door being closed. If the light does not turn off then the door switch is likely causing your problem. You can order a new door switch from the
website. Use the full model number of your Kenmore 400 Series dryer to access the parts listing for your dryer and order the correct part. The first image below shows how to open the cabinet to access the door switch. Be sure that you
unplug the dryer
before accessing internal components.
If the door switch appears to be okay, you can check the thermal fuse by
unplugging the dryer
and removing the back panel. If you have a volt/ohm meter, you can check the continuity through this fuse. Remove one wire and measure the resistance across the leads of the fuse. You should measure near zero ohms of resistance if the fuse is good. If it measures Ol (open load or infinite resistance) then it is bad and will need to be replaced. You could also test it by taping the wires going to this fuse together with electrical tape. Reassemble the dryer and see if it runs with this fuse bypassed. If it does then this fuse will need to be replaced. NOTE: Do not continue to run the dryer with this fuse bypassed. It is an important safety component that must be replaced. Also, check the exhaust vent duct system for a clog or restriction if the thermal fuse was blown. An resolved restriction in the air flow out of the dryer could cause the fuse to blow again shortly after it is replaced.
If the thermal fuse is okay, then you could have one of the less frequent failures listed above. If you need more help, reply with additional details and we will assist you further.
