Gene Café CBR-101 Reed Switch PCB Assembly factory OEM original replacement part.
Gene Café Error Condition
E3 Error: Irregular Rotation, Reed Sensor Failure. This could be caused by the Reed sensor being out of position, or the part itself failing. Check to see that the sensor has not been moved out of position, if the E3 error persists, replace the part.
The switch reeds are usually positioned close to a moving assembly. A magnet fastened to the moving assembly (away from heat) passes the reeds that close because of the magnetic field. These open as soon as the field moves away.
The reed switch is open in the absence of a magnetic field and closes once per revolution when roaster drum passes. If the magnet fell off the reed switch can’t sense rotation. The reed switch itself could have come loose from its mounting or just be out of position to sense the passage of the magnet.
Otherwise, replace the Gene Café CBR-101 Reed Switch PCB Assembly
