    Behmor exhaust temp problem

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    I've done 60 roasts in my Behmor, cleaned it as per recommended intervals but just started to get low exhaust temp readings.
    The 'A' button won't read above 110C now, previously it would peak at about 195C. The roast still seems to be completing the same as my previous roasts but I do rely on the exhaust temp as a good approximation to 1st and 2nd crack.
    So would it be a faulty sensor or something else?
    thanks in advance
    Steve

    Yeh, probably faulty sensor or an issue with the control board. Have you had a look in the vent area behind the sensor location?

    May be of use - A/B Temperature Reading FAQs

    Otherwise might be worth contacting Andy or Behmor directly - Contact & Support – Behmor

    Mine did the same thing.

    Turns out the Afterburner had failed.

    Look through the window towards the end of a roast with the light off. You should be able to see the afterburner glowing through the shield on the roof of the roaster.

    The afterburner failing (in itself) shouldn't cause the issue the OP reports, but both could be related to a common fault (e.g. a problem with the control board).

    Thanks guys, according to Behmor tech support and my troubleshooting it does appear to be the afterburners. I've contacted Andy for a replacement set, hopefully its a warranty job

    The offending afterburner, could probably salvage it. New one on its way courtesy of Andy, much appreciated.
    Not so happy with the site sponsor who sold me the Behmor and didn't want to know about it.

    Pity they can't be named and shamed so other members are aware of the lack of back-up support from them.

    I too am experiencing the same issue as Robo1111 in his OP. I purchased my machine via the coffee snobs website and have sent through two emails requesting assistance without any response. It seems too that my after burner is experiencing a problem, so how important is the after burner? I am roasting without it but the machine is not even 6 months old and I would expect it to at least last the warranty period in full working order.

    The afterburner just reduces the smoke as the roast gets cranking. It shouldn’t affect your roasting.

    It’s a very thin wire which would be easy to break if subjected to shock.

    Andy is fantastic with service, so I wouldn’t panic! I am sure you will be looked after.

    In the meantime I would keep on roasting.

    Cheers

    After my post yesterday I Googled the issue and found that it is common for the nichrome wire to break at the connection which is what had happened to mine. After repairing the connection my after burner is working again. I also received a response via email in regards to my query.

    Thanks.

    Yes, posting to a 12 month old thread in the hope I'll see it among the 500,000 posts really isn't ever the best contact method. As you rightly note Mal, using the [Contact Us] on every page of the forum and BeanBay will always get a reply!

    Nearly every case of a broken afterburner I've seen was caused by dropping the roaster or letting the door slam shut, there have been a couple that weren't caused by that but it's pretty rare.

    Also, please be careful following overseas repair guides, the USA afterburner uses a different gauge wire (twice the thickness, half the voltage) and will not work on the AU/NZ roaster.

    Yes Mal, I did use that link (twice). The email I received today was from tech@behmor.com, I shot through an email last night and within hours got a response. I have sent through 2 email this past week to coffee snobs and am yet to receive any response.

    That's weird, I always answer [contact us] and can't see any from you.

    I just tested it and it's working okay, please try again

    Hi Andy, I just sent through another email. I did find it weird not to get a response as I have read on the forum you are very responsive and helpful. When I fill out the "contact us" form and hit the send tab I do not get any form of confirmation that the email has sent.
    Like mentioned I fixed my issue and found your mention about the door slamming to be very helpful as the spring on the door does have some power. Perhaps Behmor could look into a soft closing door as to prevent this problem. I will take note and close the door manually in future and not lose my grip and allow it to slam.

    I hope my last email has arrived, if so could I just get a confirmation.

    Thanks.

    EDIT: got email response, all good. Cheers.
