Problem Cause and Solution
With Roasting Chamber
clean and empty, auger
does not turn after pressing
START button.
Roasting Chamber not seated correctly. Unplug
roaster from outlet. Open Cover, make sure
Roasting chamber is fully seated on the heat
shield of Roaster Base.
Auger drive mechanism may be damaged.
Return to our factory for servicing (see One
Year Limited Warranty).
When roaster is running,
the keypads do not work.
This is a normal condition when roasting or
cooling. Only two buttons are active while the
roaster is running. These are the ‘UP’ arrow
button (increases roasting time) and COOL
button.
You have already added 5 extra minutes,
so the ‘UP’ and ‘DOWN’ arrows will not
function. Only the COOL button functions at
this time.
The roasted beans are too
dark.
This may be normal. Different varieties
of beans may roast darker than others.
Try grinding some and brew a pot of coffee.
They may taste better than they look.
Roasting time is too long. Decrease roasting
time (press ‘DOWN’ arrow).
Make sure you’ve roasted the recommended
amount of beans per load. Fill Roasting
Chamber up to the FILL LINE (5 oz.).
I want to stop the roasting
process when the beans
change color.
If you are watching the roast cycle and the
color of the beans is correct, press the COOL
button to stop the roasting cycle. The roasting
stage will stop and cooling stage will begin
immediately. The machine will turn off
automatically after the 5-minute cooling
cycle.
