The bin switch is a magnetically operated reed switch.
The magnet is attached to the lower right corner of the

The bin switch is connected to a varying D.C. voltage
circuit. (Voltage does not remain constant.)
NOTE: Because of a wide variation in D.C. voltage, it
is not recommended that a voltmeter be used to check
bin switch operation.Diagnostics
