Topic: Help! I think I ruined my Gene Cafe! (4 msgs / 139 lines)
1) From: John A C Despres
Hi, Ken.
If the temperatures are rising at all, you may not have ruined the sensor.
The Gene Cafe is full of safety shutoffs.
Was the heater cycling on and off at about 440-450? If so, you may be OK.
Take the chaff collector off, disassemble it and scrub it clean. The reduced
airflow out the exhaust port may make a huge difference. There are 6
Phillips screws on the bottom of the collector and once removed, it will
split into 2 pieces. Now remove the 4 screws holding the inner screen in
place and pop it out. The inside of the outer screen may be coated with
"micro" chaff. Clean it all out with a good dish washing detergent or Simple
Green, let it dry, re-assemble, and give it a try.
If that doesn't work, call Tim Skaling at FreshRoast. His new number is
805-501-7731
Good luck! I hope this is helpful and the cleaning solves the problem for
you.

Ken,
Proper airflow through the Gene Cafe is very important for it to function as
intended.
If you have not already done so, the first thing to do is to completely
disassemble the chaff collector and clean it thoroughly, especially the two
screens and in between them.  There can be build up within the little holes
that can restrict airflow; I use orange hand cleaner without pumice.
Second, flip the Gene Cafe over and make sure that intake screen on the
bottom is clean; a vacuum and a toothbrush (not yours) should suffice.
While the unit is cool, also check the pathway to the chaff collector and
make sure it is clear.
Try again and let us know how it works and we'll take it from there.
Respectfully,
Eddie

Another thing to keep in mind, is the environmental temperature is high
enough to drag the beans into first and second crack... I once roasted a
batch as an experiment with the high set at 430 and the beans did reach 2nd
at about 20 minutes. It was not a very good roast, but you can still reach
the cracks at lower emps.

I did a few more batches and it did seem to improve.  However, I also clean=
ed the chaff collector as you described afterward.  So the true test will b=
e my next roast day in two weeks...
Thanks for the advice and help,
Ken
