Now have a similar gas type Kenmore with the same problem This is a Model 110.73954101 with s/n MP0204055. The unit will start and run If I hold the push to start button but as soon as I release the button the unit stops. There is no problem evident in the control panel area or anywhere else. When this unit was given to no schematic was inside the console. The door start switch was not working and the belt was broken. Bothe of these items were replaced. Any suggestions as to what direction I should go ? The push to start switch appears OK.
