Probelm mit Abluftventilator ( Problem with Exhaust Motor Replacement)

Guten Tag

Ich habe ein Problem mit meinem Bullet und zwar habe ich den Motor des Abluftventilators ersetzt und jetzt dreht dieser anscheinend langsamer. Das heisst ich muss auf F9 schalten wo ich vorher auf F2 war.

Kann mir da jemand helfen?

Freundliche Grüsse

good day

I have a problem with my Bullet and I have replaced the exhaust fan motor and it now spins slower. That means I have to switch to F9 where I was previously on F2.

Can someone help me?

With kind regards

Did you run calibration again ?

Wie kalibriere ich das?

Google Translate:
How do I calibrate this?

Hab ich gemacht! Ist etwas besser geworden musste bei der Röstung aber so ab 5min den Fan Speed immer mehr hochstellen weil er zu schwach war den Chaff nach hinten zu transportieren.

Google Translate:
I did! Has gotten a little better during the roasting but had to increase the fan speed more and more from 5 minutes because it was too weak to transport the chaff backwards.

The Bullet has 2 calibration routines. Are you certain you used the one for a V2 Bullet?

Also, check the connector for the exhaust fan motor. As I recall it’s easy to mis-connect that connector.


Google translate:

Der Bullet verfügt über 2 Kalibrierungsroutinen. Sind Sie sicher, dass Sie den für eine V2-Kugel verwendet haben?

Überprüfen Sie auch den Stecker für den Abluftventilatormotor. Soweit ich mich erinnere, ist es leicht, diesen Stecker falsch anzuschließen.

To clarify Bruce’s reply - there is one calibration routine and you need to make sure the chaff collector housing is NOT attached. The benefit is you can see and hear the fan ramping up to full in stages so you can verify the fan is actually running, and whether the speed is increasing. Either of those failures could be a bad motor (it happens) or a bad connection to the motor board.

Once the calibration is completed successfully you can then select bl16 or bl26 in the setting (or off). You should choose bl26 for the newer motor.


Well Stuart you’re right of course… my bad. I had a relapse of foot-in-mouth disease brought on by typing a reply before checking the procedure.

The Online Manual has the procedure for exhaust fan calibration. The procedure starts on Page 14. And there are separate procedures for the 120VAC Bullet and the CE-Approved 220VAC Bullet. Not anything new here except that this time I read it. Twice. To make up for last time!



And I forgot about the CE version Bruce so technically there ARE two calibration routines :wink:

So I get a pass on a technicality? All right! I’ll take what I can get! :rofl:
