Topic: Hottop won't work right after repair. (11 msgs / 270 lines)
1) From: Doug Hutson
I have the first Hottop offered by Sweet Marias- analog model. I replaced
the solenoid, which works great, and the control panel. The control panel
was not an upgrade to the newer digital ones. I also had to replace the main
circuit board because I damaged the old one when I was removing the wires
for the motor. Hottop sent a new board free of charge!
Anyway, when I turn it on and start the roast it goes into preheat mode for
about one minute and then goes into eject mode. Has anyone else had this
problem? Note that the circuit board replacement was different from the
original one.
I sent an email to Hottop last night but they have not responded yet. I was
hoping to fix it and have some good coffee soon! I have been having to drink
coffee roasted in a hot air popper which scalds the crap out of the beans.
Thanks for any assistance.

Check the voltage. If the Hot Top is not getting enough voltage it will
eject. Also check that a bean is not lodged in the eject door.

One other thing. In the instructions it tells you about a 2 or three wire
harness attaching the control board. For a 2wire harness you have to remove
a shorting clip on the board. Check the instructions. I bet that is the
problem

Anything to rid the crap from the beans. Some even buy beans that >were<

Thank you for your responses.
I have the very oldest machine- the control panel didn't even have the word
Hottop in red. Model 8828.  I cannot find any instructions concerning 2 or 3
wire harnesses attached to the control board- just 2 wire harnesses- one
small one to the thermal sensor and a large one to the main circuit board,
as illustrated here:http://www.hottopusa.com/cont.html 
This illustration matches my machine. I am not upgrading my machine at all,
except the control panel has the word Hottop in red. There are no additional
functions on the new control panel.
Voltage is fine, and the chute opens and closes completely and normally. It
just goes into eject mode about one minute after starting preheat, and
before the heating elements even have time to get red.

This sounds like behavior that happens when the chaff tray is not in  
place. Make sure it is sitting in the slot, pushed in all the way,  
with no chaff or debris behind it or underneath it.
In any case you should get in touch with Michael at HottopUSA. He  
should be able to tell you if there is any incompatibility in your  
setup. I usually only wait minutes when I send him an email.

The shorting clip is on the upgraded 8828P model. Sorry I couldn't have been
more help. Let us know what you find out from Hot Top.

The chaff tray safety is only on the new machines

You guys have been great in trying to help. Hottop sent a control panel and
circuit board- FREE- and it powered up but I got the problem of premature
ejection. I told the Hottop to think of baseball or England, but it didn't
work. I am embarrassed to admit that I finally traced this problem down to a
loose connection to the heat sensor. DOH! It is now working perfectly and
Tom has lost a sale for a new Hottop, at least for now. The machine is
getting old!
Thanks again.

I just put together the reasons I don't - and won't - have a drum roaster
designed to be used intermittently . Not even rated for Intermittent
Commercial/ Amateur Service, (ICAS) like the vacuum tube power ratings in
tube manuals back in the day.
How often do we hear about the "fire that started while I was roasting?"
While Rex the Roaster was standing there roasting, the machine "melted down
and nearly started a minor conflagration." Still wonder why the commercial
manufacturers won't sell a scaled-down roaster for multi-tasking home users?

Do your reasons con include a tendency to multi-task, an abbreviated
attention span, or an inane fear of cylindrical appliances? I have been
roasting in a home-made drum for a few years and find it quite rewarding.
