Topic: Decreased Behmor performance (13 msgs / 193 lines)
1) From: Mark Sellers
Hello everyone,
 
Not to beat the Behmor horse again, but I've noticed that mine hasn't been able to roast as well as when I first got it (3/08).  It previously would roast 1/2 pound to Vienna if I needed using either the P1 or P2 settings for 1 pound.  It won't get to that point any longer, and MAY hit 2nd crack using the max time before it enters the cooling cycle.  Many times, 2nd crack hasn't made any appearance before it starts cooling.  I've measured the line voltage and it's running ~117-118v.  Does anybody have any suggestions about what may be happening?  I noticed that you can send your 1st and 2nd crack times to Behmor tech support and they'll help you troubleshoot.
 
Thanks to Tom (& the gang) and everyone else who has helped me start my new 'hobby'.  The information and green coffees available have been fantastic!
 
Mark

Have you been cleaning the machine? Running an empty roast after the
5th roast? Cleaning the inside of chaff and using Formula 401 or
Windex on the inside?

Have you been running your self-clean cycles regularly (1/2 lb.,  
empty drum, every fourth or fifth roast)?

Is the right hand side wall nice and bright shinny in the area between 
the 3 screws?

I have to admit that I haven't been running the 'cleaning' cycle as often as I should.  The right hand side doesn't look too bad.  I suppose I could clean it, but am hesitant to use any cleaners other than a damp terry-cloth towel.  I saw the pics in the coffee library that show taping over the thermocouple and some of the top element of the Behmor.  I carefully tried 2 batches using these mods and it was like a new machine!  Cut the roasting time down by quite a bit and produced excellent batches of Nicaraguan decaf and Sumatra Batak.

Joe says to use Simple Green (cheap at sams club) to clean the machine
inside and out.  He told me that in a situation like this you need to
make sure the sensor on the inside right near the back is kept clean.

7) From: Dave Huddle
I've been using Simple Green on various roasters for several years.
Good Stuff!
I'm glad to know that Joe approves its use too.
After EVERY roast, I vacuum the roaster inside and also around the
various vents on the case, then wipe the interior with a paper towel
dampened with Simple Green, then with a slightly wet paper towel.
No problems so far with about 77 roasts.
I do run it empty after every fifth roast as Joe has instructed.
Now that I''m roasting inside my ALMOST  finished laundry/roasting/dog
 room where the temperature is fairly constant, I've noticed that
roast times are consistent for a given bean.

If the right side is bright and shiny you can skip the  tape.  Blocking 
the smoke incinerator can prove counter productive in the long run.  Use 
something like simple green and then polish that area with Mothers 
Polish.  Run cleaning cycle every 4th roast.

Simple Green, Windex or even Oxi-  Clean will give the same effect.

Joe Behm, the Creator of the Behmor told me that it should be cleaned
(the sensor) and he is the one that suggested simple green.
Joe can be contacted through his web site if you want to ask him directly.

Mark, contact Joe Behmor, he was real good about getting me a new afterburner shipped when mine "died" Other that that, I've worked my BEHMOR pretty hard at times and I haven't had a decreased performance problem so far.

on the inside right side of the roaster is where sensors are located.
in the book or on the web site they mention after many roast it is good 
idea to throughly clean this area.

13) From: Alchemist John
I would agree - since I came up with both those mods.  The air block 
is especially true for a roaster that was performing acceptable.  In 
that case, blocking is just a work around, not a fixing of the 
problem.  That area where the thermistor is located is critical to 
keep clean though.  That is how the Behmor judges it's position in 
the roasting profiles, and anything that gives false or biased data 
(darker area) will affect the profiles.
