Re: Kenmore Dryer fuses
Don't worry about the thermostats they wont stop the drier from running set your meter to continuity should have a wave symbol on it touch the leads of the meter together to make sure its working should read zero then touch the leads to each end of the component and if it reads ol or open its bad any time you take a component reading you must make sure at least one side of the component is unplugged to prevent getting a false reading

1. No power to the dryerMake sure there's power getting to the dryer. Check for a tripped circuit breaker or a blown fuse. Check the wall socket for power with a voltmeter or by plugging something else in.
2. Door switch / Door switch actuator lever The dryer would not start with a broken door switch. Replace the door switch if found defective.
Most dryers have a door switch actuator lever - when you close a dryer door, it presses against the lever, which actuates the door switch. If the lever is broken, the switch would not activate and the dryer would not start. Replace the lever, if broken.
Note: Door switch actuator lever usually comes with the door switch assembly and it is recommended to get the whole assembly since there is almost no price difference between the door switch assembly and just the lever. Check your model for more details.
3. Thermal fuse Most dryers have a thermal fuse, which burns out when the dryer overheats, in which case the dryer will either not run at all or stop heating. The fuse is usually located on the vent duct, inside the dryer. A blown fuse will show no continuity when measured with a meter. Before replacing the fuse, make sure the blower wheel is not broken or clogged, and there is nothing blocking the venting.
Note: It is recommended by most dryer manufacturers to replace a hi-limit thermostat when replacing a thermal fuse.
4. Timer Replace if defective (note: uncommon problem).
with power disconnected
if any wire disconnected before any test, reconnect & test dryer, reconnect wires after each test
disconnect wires from start button and test, conduct when pushed, no conduct when release
if fail replace start button test dryer
disconnect wires from door switch and test, conduct when pushed, no conduct when release
if fail replace door switch test dryer
follow leads from start button to relay(relay is first device connected to start button), and make sure all wires connected at both ends. If any wires disconnected, test dryer
locate thermostats and thermal fuses on fan housing and ducts
individually disconnect wires from each and test. conduct good, no conduct fail
replace any failed thermal fuse or thermostat test dryer
if all prior test OK
replace relay, test dryer
