Topic: Behmor suddenly not getting hot enough? (22 msgs / 719 lines)
1) From: michael brown
Hey guys,
My behmor has suddenly stopped getting as hot as it normally does.  It took=
 me a while to get used to the whole programming thing but once i got a han=
g of it i've never had this problem before and it's happening with all the =
beans across the board.  =
i usually use P3, P4, or P5; i usually subtract down to somewhere around 9-=
11min before starting.  then add back once things get rolling.  now suddenl=
y i'm not even getting close to the 2nd crack.  it seems like i remember so=
me discussion a while back (and i've searched the archives) about the locat=
ion of the heat sensor and keeping it clean.  i think i remember a picture =
someone took??  =
i've done the calibration cycle every five roasts religiously as suggested.
i took off the back, the side, and various other parts and cleaned off a lo=
t of gunk that has accumulated over the past year, not sure if that was som=
ehow interfearing with a sensor of some type.  the timing couldn't have bee=
n worse because i swore i'd have several pounds of coffee for some co-worke=
rs by the week's end and they want good coffee and i'm not comfortable call=
ing this good coffee!  =
any ideas?  something i'm missing?  i sure hope this msg gets on the list s=
ooner than it usally takes my MSN account to get it up there because this i=
s kind of time sensitive.  =
please help!  ~~have i sounded desperate enough yet?  =
thanks, =

Two things come to mind. First Ambient Temperature. Have you moved your
roaster some place new? Someplace cooler than it was before. Have you put it
on a long extension cord? Is the right hand side of the inside of the
roaster dirty? If so clean with Simple Green or Oxy Clean and finish with
Windex.

4) From: michael brown
the roaster has not moved.  it's still on the side porch with no real chang=
es in temp this past week.  but it did have an extension cord.  i got an em=
ail back from tech support at Behmor they strongly urged me to do what your=
 saying.  so i've moved my operation closer to the wall outlet, no more ext=
ension cord, and i'm buying some simple green or oxi clean tonight to polis=
h off the inside.  i'll let you know how it goes after that.
while i'm at it, how about some discussion on "seasoning" a roaster?  my dr=
ums for the behmor have collected a layer on the little directional heads i=
nside the drum (don't know how else to describe what those things are).  is=
 that conisdered seasoning the drums?  or is that gunk that i should clean =
off with the simple green as well?  i know when i first got the machine, th=
e first couple of batches almost tasted metallic.  after a couple of roasts=
 that was gone.  if i clean off the inside of the drum will i get that tast=
e again?  i guess i should clarify, it looks like heat scalds in there, i'v=
e tried scrubbing, but nothing comes off.  maybe the simple green will help?
thanks guys and gals

5) From: Sandy Andina
Because I couldn't find Simple Green in my supermarket or Target store  =
at first, I tried scrubbing the sensor area with Seventh Generation,  =
Formula 409, and even Bon Ami (same thing as Bar Keeper's Friend).  =
None of it really worked, no matter how long I kept it on before  =
scrubbing. Finally found Simple Green at Home Depot--sprayed some on,  =
left it on for an hour, and the brown gunk wiped right off. Took  =
several "rinses" of water on a sponge followed by drying with a paper  =
towel, plus an empty-drum 1/2-lb. cleaning cycle to get rid of the  =
cloying Simple Green scent. But I have had no further problems with  =
under-roasting.

I've called around and found its at Home Depot. I'm going after dinner tonight. And I'll take pictures of before and after and link them somehow. Thanks for all the input.

9) From: james McDougal
Can someone explain a little more about the sensor on the right side of the
Behmor?
What does it sense? Does it control the on/off rate for the heat?
Thanks, Mac

10) From: Alchemist John
It is a thermistor that indirectly detects the =
chamber temperature by actually measuring the =
wall temperature.  When the wall in that area =
gets particularly dirty, the wall absorbs and =
holds more heat than when it is shiny and =
reflective.  The result is that the sensor gets =
hotter faster, so it cycles the heating elements =
off, thus making the roaster cooler and roasts =
longer.  In particular hot weather, the sensor =
does not cool as quickly on the back/interior =
side and again, it falsely thinks the chamber is =
too hot, so cycles the elements more often.
Clear?
Also, the every 5 roast burn is not a calibration =
run, it is meant as a dry burn to burn off build =
up.  I find just a periodic spray and wipe down =
with simple green is much easier and more effective.

11) From: Gregg Talton
Michael,
I've found that my Behmor roasts better in a cooler ambient temperature.  I
too had a problem this past week. If I recall, Mr. Spann the weather
man says you guys are/were having some warm weather in the Magic City (80+
degrees).   I have some Simple Green and have cleaned the interior and it is
better.  I don't know if the weather has anything to do with the changes I
have experienced or if my machine just needed a good cleaning.  But it
worked great when I used it in the garage and the ambient temperature was
about 51.  This week we've had temperatures in the mid 80's in Charlotte.
Good Roasting!  (I'm a native of Shelby County).

12) From: Allon Stern
So, I was curious about Simple Green, and why it works while other  
products don't, and what toxicological effects it may have.
The MSDS for it shows that it is essentially non-toxic, which is good.
It contains 2-Butoxyethanol,http://en.wikipedia.org/wiki/2-
Butoxyethanol which is probably the main solvent responsible for its  
cleaning properties. In any case, the amount of exposure from using  
it to clean your Behmor is vanishingly small.
I may get some to clean up my iRoast2, which is getting a little  
crudded up.

i'm not sure why the simple green works but it does!  just to follow up:
i used the simple green and it worked amazingly!  here's a link to the area=
 i paid the most attention to:http://behmor.com/pdf/Manual%20Update%202-06=-08.pdf
i also get rid of the extension cord.  also one of the things behmor tech s=
upport told me to do was to do a calibration (dry roast) and watch and reco=
rd at what times the heating rods in the back cut off and back on.  after a=
 thorough cleaning, i did another calibration roast and the times were TOTA=
LLY different.  i roasted some Yemen Sana'ani (7oz and 7.3 oz) on P4D then =
P5D and i got my old roaster back!  its truely amazing how much the subtle =
differences over time had eluded me.  then when its working the way its sup=
posed to i'm floored at how great this thing is!

That product uses isopropanol as its solvent - basically rubbing

I doubt it will work very well for this purpose.

Another great product for removing coffee sludge is Oxy Clean. Regular
Windex after each roast works well also. But not as well if there is any

Urnex (Cafiza) and JoeGlo are slightly caustic--you might want to be  
careful with those. (I never had "dishpan hands" until I started using  
Cafiza to clean portafilter parts). When I began homeroasting, I used  
to wear a rubber glove and wet a folded cloth with a mild solution of  
Cafiza to clean the brown gunk off the inside of my iRoast chamber-- 
make sure you wipe it off once the brown stuff is gone and then rinse  
well (several wipedowns with fresh paper towels wet with water, drying  
them in between).

19) From: webviking6
I had a similar problem, I was planning on roasting two 1 pound batches, =
after the first batch, I let the machine cool down for 30 minutes or so =
and threw the 2nd pound in on an 18 minute P2 roast.  After 12 minutes =
or so, I flipped on the light to check the roast and the beans were =
still completely green.
"What-in-the-hell," I thought, "did I burn out the heating element or =
something."
So I went out to the Behmor website and looked through their updated =
online manual and found out that occasionally you need to completely =
unplug the machine to reboot the microprocessor.  Who knew?  LOL
Unplugged it for 10 seconds, plugged it back in and I was back in business.
I had visions of forking out another $300 for a new Behmor, because I am =
far beyond the point where life is possible without my daily fix of =
excellent fresh-roasted coffee.
I'm glad it turned out to be so simple.

Yes, everything for the second roast was completely cold. Put the beans =
in, turned it on, the drum turned, the clock counted down, but the =
heating element apparently never turned on.
That's only ever happened once to me, and I'm still not sure why. That =
was a couple of months ago and it hasn't happened since either. And I =
also haven't unplugged it between roasts since then either. Just one of =
those things, I guess.
