Kenmore portable dryer 89722

Dryer runs then shuts down wont start up for an hour:
Bad motor windings

check the micro switch on the door . worn door hinges/broken door hinges will not activate the micro switch and so the unit will not turn on as it thinks that the door is still open

Sometimes the venting in the dryer needs ton be cleaned out as it plugs up and the high limit thermostat makes it short cycle on the heat cycle.

Sounds like the belt has broken. You could probably also use new drum support rollers. Check out this site which shows how to change a dryer belt:

It's not a difficult job if you're comfortable working with hand tools.

my kenmore dryer 80 series wont start the start switch just buzzes and the drum does not turn i put a new switch today vacuum it and check all belts they seem fine dont know what else to do

Bad thermal fuse

This sounds like you may have blown the thermal fuse.  If you turn the dryer around facing the back, remove the screws holding the back panel on (be sure to unplug the pigtail from the wall!!!).  When you remove the back panel, down towards the bottom, you will see a plastic piece (could be long and square, or rounded type.  Do believe it will be the long type) with 2 wires going to it.  It has a screw that holds it it.  This fuse protecs the unit and motor from excess heat and electrical issues.
