We picked up a used Kenmore Elite. All of a sudden, no heat. Got the element housing checked, all continuity good. Was suggested to change thermal fuse and/or thermoster along with cleaning out all lint vents and such. All was replaced, now no power. Any suggests

I'm assuming you have power to the outlet? I would use a voltmeter and start from the terminal block on the back of the unit and start testing wiring to see where the power is lost at. Could be the start switch, door switch ar many other places. Testing is required though
