If you notice the diagram that Jabko has posted you will see the thermistor value chart, this shows the resistance value the thermistor should have at a particular temp.  Having already changed the safety and the heater there is only the thermistor and the board left.  The thermistor is the lkely culprit as already stated, the older ones are prominent for going bad.  I have had them show to be in spec and still not work right, so I change them on every job I do automatically (besides there in-expensive anyway). Trouble is there is no real way (I know of) to test the board. Change the thermistor and keep an eye on it if it does freeze up you will be changing the board,  if not then you GTG......good  luck ....check back

This is the DAY that the LORD has made, REJOICE and be glad in it.....
