Hottop Roaster Model Identification

When ordering parts such as the control panel, eject mechanism, the temperature sensor, main circuit board, and more, it is important to know exactly which model you have.
On the control panel and on the bottom of the roaster you will find a model designation such as, "KN-8828B" or similar.

DO NOT USE THESE TO IDENTIFY YOUR ROASTER!

HOW TO IDENTIFY YOUR ROASTER

All Hottop Coffee Roaster model designations can be broken down into four specific positions in the model number. The color codes here coincide with the rest of this page (ie. yellow will always designate "Position 2" on this page):
 
Position 1Position 2Position 3Position 4
Base ModelControl PanelSafety EjectThermocouple

Pick the correct option from the four Position choices below to verify your model:

POSITION 1

For all our coffee roaster models, the basic designation begins with KN-8828.

POSITION 2 - Control Panel


Original model has
no further designation.
KN-8828
This is a
"D" control panel
KN-8828D
This is a "B"
control panel
KN-8828B
This is a "P"
control panel
KN-8828P
This is a "B"
control panel for the
KN-8828B-2K+

POSITION 3 - Emergency Manual Eject Knob

If your machine has this knob located under the
main fan on the back of the machine then it
will have a "-2" in the model designation.
If it does NOT have the knob, then there is no numeral in that location.

POSITION 4 - Temperature Sensor

Remove the front cover from the machine and look into the roast chamber. On the rear wall you will see one of these three thermocouple placements seen here:

Models with this flat "button" temperature sensor
DO NOT have the "K"
designation in the model name
Models with the above K-style thermocouple
DO HAVE the "K"
designation in the model name
Models with the dual K-style thermocouples have the
"K+"
designation in the model name

Put it all together

of the following:
no designation or

D or B or P

No knob = no numeral

Models with knob

NOTE: "Customized" models which have been partially updated by customers could create roasters such as the KN-8828-2, an original model updated with emergency manual eject, or KN-8828B-K, a machine updated to "K" functionality, or dual thermocouples, a KN-8828B-K+, but the emergency manual eject option was not installed. These are not actual factory models. All factory models are listed above this paragraph.
