Topic: heat gun bread machine (12 msgs / 271 lines)
1) From: jay hobaugh
Well I went out and got an  bread machine at goodwill. the loaf pan is only 5" sqaure and only has an on off button.(Mister Loaf) but when I got it home and let it go it ran for a 20 minute inital mix cycle, I thought awesome, cool, I can go for as long as I need to, no problem. buzzzz wrong answer. I have done about 5 roasts with it over the last week. two have been good. the other 3 I tried to take the bean to the second crack and apparently got the bread machine too hot cause it simply stopped. one stopped at 10 one at 9 and the last one at 6 minutes. the last two were just today. So I guess my question is this- how easy would it be for a guy like me with little knowledge of the inner workings of any given appliance to take this sucker apart and make it just spin without worrying about the heat, like disable the cook cycle or something? I saw a couple of people who do the HG/BM method on the archive. but I guess this would be a more general electrical parts
 question. maybe trying to fix this would help me to mod one of my 4 air poppers. cause winter is comming soon.
  Thanks for any respones.

I've been using the Heat Gun/Bread Machine set-up for a couple of
months now having only replaced the original turning paddle. I myself
have been curious about how easy it would be to control the motor by
overriding the computer programmed functions. I've taken the whole
thing apart, but have been unable to figure it out. I haven't had any
troubles with overheating or shutting off. The churning cycle on my
breadmachine lasts for 15 minutes which works fine for me and the one
time I preheated the bowl with the motor running, I had to restart the
cycle but there were no issues with it stopping all together.
My vote is that you can figure out how to fix it if you take it apart.
What's there to lose if you are currently working with a bread machine
that is not working properly for you? I'll continue to modify my
breadmachine if need be because the nice thing is, if it breaks, I can
find plenty more at the thrift store...

My two cents.
the motor has two leads for power to make it run to turn the paddle
the heating coil has two leads for power to make it run.
disconect all the computer crap, circuit boards etc etc..
run the electric directly to them,  get a few two dollar switches at 
home depot etc that can handle about 10 amps.  (should be a few bucks 
each if that)  and use them to control the juice to the heater / motor....
id say if you are putting heat into it, you want the motor running to 
turn them........ very crude simple setup. hook the motor leads and the 
heater leads directly to the plug in the wall... plug it in to heat and 
stir,  unplug when they are done... end of story...
granted this can be refined greatly, but for control of the electric, it 
should work fine for your purposes.... 
P.S.  Id put a fuse in it or throw it on a circuit of 15 amp max,   in 
case something were to go wrong, short circuit, heater grounding out. 
yadda. whatever... it burns the fuse / cuts power......  just a safety 
note..

  For some reason once my machine is hot thats it it wont restart again till it cools usually 30 min.unplugging wont work either I stirred and hit it with the gun till I thought maybe it was done. I'll taste tomorrow morning. (classic sumatra)

Point well taken...I will try to tear it down on friday, yay, my next day off.

8 roasts in, I'm as pleased as I could be with my oldish (1999) model 
5820 Sunbeam 2 pound bread machine. I set it on the dough cycle, which 
will knead bread/stir beans for 20 minutes. No mods. I picked up a spare 
the other day for $3 at a thrift store.

This is a multi-part message in MIME format.
I'd go the route of re-wiring for manual control of the heater already
there. Split out to a variac for good variable potentially boosted heat
control if needed of course :-)

Steve, the motor in bread machines must develop substantial starting and
running torque. It has to mix and knead the dough and dough ball.
They make pretty good use of a permanent split capacitor (PSC) motor. To
bake a loaf, the motor wouldn't run continuously. Especially during the Rise
and Bake cycles.
It sounds like you're hitting the run times flashed into the firmware for
the different bread cycles. You could power the motor directly instead of
letting the internal program cycle it. Just remember- you'll have a good
home roaster, not a Diedrich.
Neither the heat gun nor the bread maker paddle motor should be run
continuously. Under no load, the bread machine motor actually gets as hot as
it will with full load.

Hi Branden,
Here's what I have gleaned in rigging four of these things so far:
1) The heating element can be disconnected with no problem.
2) There is a safety thermocouple (usually a white wire with a woven 
sleeve around it that touches against the loaf pan.  It can be 
removed from the loaf pan, but cannot be disconnected, as it will cut 
out the power to all the circuitry.
3) This one is harder - by trial and error I have been able to find 
the place on the circuit board to put a simple toggle switch to turn 
the motor on and off.
I think it is better, safer to go through the electronics than to 
skip them altogether.
Caveat:  If you don't know about fundamental electrical safety, put 
down the diagonal cutters and step away from the wires.  Stop reading 
immediately!   ;^)
Still here, eh?  OK.  Check on the circuit board and see if there is 
a transformer and/or a start/run capacitor for the motor.  Look also 
for connecting plugs.  There is probably one that has red, white, and 
black wires coming in.  Tracing these wires will likely lead you to 
the incoming juice from the mains.  There is probably another plug 
with several much smaller wires.  These smaller ones are the low 
voltage side that go up to the control panel.  These are the ones to 
check for installing your switch(es).
I hope that helps.  If you get shocked, you can try to call me.
I'll be in Argentina.  (He-heh.)

  I want to thank you for this information. it is exaclty what I was
  wanting to know. my bread machine kept turning itslef off because
  of the safety thermocouple. It was pretty simple to do once I got into 
  there. had to use liquid wrench on some stubborn screws that wouldnt
  turn. now my 6-9 minute bread machine roasts can be as long as
  I need them to be !!!!!!
  Thank you very much.

Cheap, simple, hands-on and probably responsible for the best roast I've
ever done.
