Take it apart and clean (brush and vacuum) it thoroughly.  If we are 
talking about the Alpenrost, mine quit several years ago in mid roast 
because it had accumulated enough chaff inside the housing to block 
the cooling airflow, overheat and trip a resettable thermal 
sensor.  Mine came back to life once I let it cool and vacuumed it 
out, but I would bet there is also a one time thermal fuse somewhere 
that could have tripped in her case if it is totally dead.

It reverses the drum rotation to dump the beans but not the fan.  The 
simply fan runs continuously at the same speed.  There is a motorized 
damper at the fan end that closes to direct most of the airflow 
through the interior of the machine (to cool the housing) during 
roasting and then opens at the end of the roast to cool the beans.  I 
don't remember if there is any sort of sensor on the damper, but make 
sure it operates freely.... it can get gunked up with chaff and debris.

Mine is close to 20 years old now and still works great when I use 
it.  But I do have to clean it out once in a while.

Does the display light up or is it totally dead?
