Hi! Looking for a legacy inlet temp sensor on 13 yr old Gene Cafe. It seems they've changed it and now you need new mother board and new sensor. Any ideas where I can find compatibile old one? Mark

peveleth, It is better if you start a post in the forum with your question. These shouts go away in time.

Gene Cafe is DEAD!
Army Coffee
After 3-years, my Gene Café decided it was done. I went to start my roast yesterday and while everything turned on, the Drum did not rotate! Hot air was blowing through the Chamber, but no sound of the motor even trying to rotate the drum.

Should I assume it is the motor that needs to be replaced?

What other possibilities are there?

Gene Café Support is non-existent in my eyes. Does anyone have a phone number where I can talk to someone and order parts?

The Silver Lining in all of this was the fact that I found a guy who has a Hottop 28B that he is not using and last night he took my offer to buy it. One thing for certain is the fact that Hottop has great customer support.

I want to repair my Gene Café and any and all your suggestions would be greatly appreciated.

Hi, Drew.

If I remember correctly, everything in the GC seems to have been commercially available. Open your up and get the number from the motor and see what you can find.

I'm afraid we're on our own out here for now until someone decides to get into the GC repair business.

Drew, perhaps it's a bit early to jump to conclusions just yet... unless you found/heard signs of wear and tear on the drum assembly and motor earlier. Is there any evidence that the plastic gears might be failing because of their exposure to heat? Perhaps, it might be something relatively simple like a bad connection, a faulty switch, a failing wire, etc... A volt-ohm meter, would be helpful here.

On the other hand, after all those years of experience on the GC, I'm sure that you would very much enjoy discovering the new challenges of roasting of a Hottop.

The Genecafe is being supported now and parts are available:
contact http://www.batchcoffee.com/
I believe it likely is worth fixing if for no other reason than to pass the good deal along to get someone else started in home roasting. Pay it Forward!

And I agree that Hottop has great customer service. Grin

Ciel;
I took it apart last night and all waires appeared to be connected and nothing on the motor is indicating power. Will explore more today and I do want to fix it because it is nice to have one in "Stand By" mode

Randy;

Thanks! I was tracking that and now just need to ensure I get the right parts. That said, I have the Hottop ready to go for my first roast TONIGHT!

Have we talked on the phone before about converting a 8828b into a 28b-K or 28b-2K???

Hottop Team was super friendly and very responsive! Still don't know if I will convert it to a 2K or just a K...thoughts?

Drew, in my experience, the single most important first mod to consider would be a permanent BMT probe.

Based on your comment, I am assuming you are making the statement that replacing the button with the thermocouple in not important compared to a BMT Probe?

Drew,
We (I) have completely updated the upgrade page on the Hottop website. It is now far more detailed than it was before. The "-2" conversion is nice, and the "K" conversion is OK but if the straight "B" is working well it probably is not worth it. The reason is that while the "K" responds a bit faster, the "old style" system is consistent from roast to roast. If you have a control panel fail then the "K" upgrade makes sense and then you can do the "-2" at the same time since you will have the machine most all the way apart anyway.

Glad to see these full upgrade kits listed now!!!!

I just finished a -2 (manual bean dump) upgrade of my standard 8828-B with the button style roasting chamber probe.

I can say that the switch over to the manual bean dump parts was not difficult but it did take a little time as everything down to and inducing the main machine chassis needed to be revolved and replaced.

Well worth the time and effort to get the rear lever that opens the bean dump door. It has been installed for the past 4 roasts and for 2 of them I needed to use the manual bean dump as the other mods I made froze the machine and I needed to power off then power on (pull and reinsert the AC plug) to get it started again then I just pulled the manual eject to remove the beans while the machine ran the cool down cycle.

I decided to not update to the K type machine thermocouple as I was getting good results with the older type probe but it is up to the individual whether they go with a more accurate type of probe or stick with the older type.

Somewhere I read that there was an updated CPU/PROM for the main board (or the control panel board) should I contact you directly about this or can you provide the info about it in here?

In another thread (http://forum.homeroasters.org/forum/v...post_51146) there was talk that the B and K2 models had different max temp (safety dump temp) settings (428º & 435º). Is this correct? Would an updated chip move an older style roaster to the higher safety temp setting?

Not planing on doing a charcoal roast but a few degrees headroom can't hurt

Drew, you might first like to take a quick look at a 5 Part Series entitled "Enhancing My Hottop". Once you have done that, perhaps you might post specific questions in the relevant threads.

In regards to the eject max temp, it is now 435. It use to be 428. Whatever programming has changed, replacement chips are not available at least as far as I have heard.

I found the page on the Hotpot site that is the procedure to replace the chip

http://www.hottopusa.com/chip.html

could you find out if this would change the dump temp setting and what else might be different (if anything) between a replacement and the existing one on the older B models?

Thanks Randy.
That's a good example of an important yet inconspicuous change in Hottop roasters over time. Do you think that it might be possible for the website to consider providing a table summarizing these inconspicuous changes by model year?
