DRUM LAMP

The drum lamp is an LED array. It comes on when the POWER button is presses and goes
off when the door is locked at the beginning of a cycle. It can be turned on during washer
operation by pressing and holding the RINSE+SPIN button for three seconds; it will turn
itself off again after 4 minutes. It also turns on at the end of any cycle and extinguishes
four minutes later.
Testing between pin 1 or pin 3 and chassis ground at the lamp connector when the lamp
should read approximately 16.5 V whether the lamp is on of off. When the
DC
microprocessor switches the lamp on, the current is passed to ground through a resistor,
effectively dropping the voltage at the lamp to 6.5 V .
