I noticed on my last roast that exhaust temperatures were low so logged a support request with Behmor who suggested it was the afterburner and provided details on where to buy a replacement part (CoffeeSnobs) and how to replace it, plus also a possible fix if the heating element had snapped.
I got in touch with Andy to buy a new one. He helpfully put one in my shopping cart, but also gave further instructions on possible repairs. It is a simple job to dismantle and check the fault which was fixable, so my machine was back up and running in 15 minutes with no need to buy parts.
Great service again from Andy!
