Topic: Problems with Gene Cafe (6 msgs / 319 lines)
1) From: Jeff Broiles
I have been happily roasting using a Gene Cafe for a little over a year now, but I have recently been having some problems. I usually like to run it at 350 -375 for 5-6 minutes, then set the temp to 482 until 10 - 30 seconds into 1st, then back the heat off to 456 - 460 until the end. For my last few roasts though, the thermostat is switching on and off once it reaches 450 degrees. It can still reach 482 when I am preheating, but it takes much longer than before, and it may not get there with larger charges, i.e. 185 grams, which is the most I roast per batch. 
Thanks in advance for any suggestions.
-Jeff
P.S. I'm not considering a new roaster at the moment, only looking to fix Gene.

Jeff,
It sounds like a problem I had.  I've attached a response Eddie Dove gave=
 when I
asked about it.  I just started another thread reporting a successful =
repair,
after calling & later sending in the GC.  BTW, it did take longer to get =
the
unit back than I was told ... but the problem was on the shipping end of =
things.

Dave,
It is certainly possible that the Gene Cafe is failing, but try some
things first that will help you determine the cause and possibly help
Tim Skaling (see below) figure out the problem in the event you need
to contact him for warranty repair.  It sounds as though it may have
an airflow problem and if not, it may be a heater box or thermostat
problem.
If you have not already done so, flip the Gene Cafe over and give the
fine screen underneath a very thorough cleaning.  I use "computer
cleaning" brushes that came as part of a kit that connects to the 1
1/4" hose of mini shop vacs.  Be sure to brush the screen with
something, maybe a toothbrush.
At the other end, make sure the chaff collector is not clogged between
the two metal meshes.  The chaff collector comes apart easily with the
removal of some screws.  Once it is apart, be careful not bump the
"pegs" on anything, as they can snap off rather easily.  Also, make
sure the path along which the chaff travels is clear as well.
Afterward, from a cold start set the Gene Cafe to 482F and 30
minutes, and hit start.  Note its behavior and how long it takes to
get to 482F, or if it even does.  If on the way up, the temperature
starts to drop before it gets to 482F, give Tim Skaling a call and
let him know what the Gene Cafe is doing.  He may be able to diagnose
it over the phone and work something out so you don't have to send the
whole unit back.  Tim is a great guy and has always been very helpful
to me even though he often appears to be overwhelmed with the volume
of work he has.  If he has to send you a part, be sure to ask him for
some spare "rubber bumpers" for the chaff wipe.

Jeff:
You may have a bad thermo and I believe you can swap that out yourself. I had min open
be fix the little rollers on the drum ends. Seems they in fact were not broken but had slipped.
I was sent replacements asap. The machine is very simple to work on...
it could bve a lose connection in there so maybe just taking out the drum and looking will do the trick.

When I sent mine in, I asked for some spare rubber bumpers for the drum, =

OK Dave, I see
After I took mine apart I have never been able to get those two half moon plactic pieces back in!
ginny
the ones that sit under, on each side of the drum? oh well, works fine anyway.

David and Gin,
Thanks for the suggestions. I have not been very good at cleaning the Gene Cafe, and can see that the intake screen has picked up some gunk. I'll clean that and the screens on the chaff collector, and see if that helps. If that does not work, I'll give Tim a call.
Cheers,
-Jeff
