I am preheating and once I reached 75+ degrees the bullet beeps and flashes “CHAF.” I opened Roasttime and I noticed that the coil fan 2 was jumping all over 3,000 to 10,000 to 4,000 to 60 to 0, and then the cycle would repeat. Each time coil fan 2 hit zero, it beeps and flashes CHAF. I had recently cleaned the chaff collector and the impeller fan and did a successful roast afterward, but just to be sure I removed them and cleaned them again, but same result. Any thoughts?
The log shows alternating Error 35: Coil fan 2 blocked and then Error 34: Coil fan 2 low speed. The troubleshoot link takes me to the manual and then addresses neither of these Error codes.

Please take off the motor cover and check that the connections to the small 60x60mm fan in the back are OK. Also check that no wires are being squeezed.
Almost seems like two signals to that fan are shorted together.
