If the door's closed how do you know the light is out?
Bob
I put a power-meter on the refrigerator, and found that the power consumption
would go up 30W when the door was open vs closed. I then temporarily removed
the light and observed the same 30W power consumption difference. I concluded
that the light is the sole source of power consumption change and that it was
clearly not powered when the door was closed.
Examination of the refrigerator wiring diagram further supported this
conclusion;
a door-switch is wired in series with the light bulb. Once I discovered this, I
experimentally
pressed on the door switch when the door was open and I directly observed the
light going out. Given the door mechanically depresses the switch when closed,
I am comfortable with the conclusion.
