I did several roasts in the last two days. I noticed that the beans and the cooling tray were hot on Thursday for one roast, but paid no attention.
Today, it happened for EVERY roast. I watched and listened carefully - it appears that the blower fan below the cooling tray has died. I tried Googling for any suggested fixes, but found nothing. Then I searched within several web sites like coffeegeek and home-barista, but still came up empty.
Any suggestions from you experienced Hottop users out there? If not, I plan to contact Michael at Hottop USA on Monday.
