Topic: iRoast2 temp (?) issues (was voltage issues) (36 lines)
1) From: kevin creason
Since 114v isn't sucky,  I did some more testing with no beans and have been
changing one-thing at a time.
Used the preset #1 for all tests below, alternating between two power bases
and pots that behaved the same and allowing for cooldown time (it was a very
long, tedious weekend). All tests were indoors and the AC was set to keep it
around 76:
1. held down the pot button (so obviously sans pot) and ran a complete
roast. Temps were in the 180 F range, but it completed.
2. Pot on w/out lid-- completed-- but forgot to write down the temps, I
think it was under 350 F.
3. Pot w/ half lid but no chaff collector or screen-piece of lid-- completed
350-400 F.
4. Pot w/ lid and no chaff collector-- completed ~ 430 F.
5. Pot w/ lid & chaff collector (but no beans) 430-450, failed. (countdown
timer continues but it stops blowing and heater element is no longer
glowing). Stuck a big box fan to blow over unit once it failed and when it
cooled to 250 it started up again. When it reach 430-450 it stopped again
(about :30 to go before cool down). Put box fan back on it and it started
again, but was in cool-down and couldn't see the temps anymore.
I scrubbed and scrubbed on the screen and chaff collector. didn't make a
noticeable difference.
6. Ran 5/8 cup of decaf beans (I don't have my notes, I think it was 4.8 oz
by weight) and still using preset #1 I had too-dark beans with 3:00 to go so
I put it in cool-down.
I think it is just running too #!$\n$${@}%#$ hot here in Houston. The
problem did start in March when outdoors started getting into the upper
70's.... Looking back I also had started running smaller batches because
they weren't circulating well.
Ideas? IRunoutofem2....
