Description
A refrigerator door-light switch can be a small component with an outsized effect: it tells the cabinet-light circuit when the door is open or closed. Dometic number 3851000012 appears in service drawings for selected RM3962 and RM1350 configurations. This is a door-operated interior-light switch, not the refrigerator power selector or thermostat.
The drawings show the older 3851000012 switch with a service direction to 3851000020, described as a short-arm switch. That number relationship is useful when tracing a repair, but it does not establish that every used switch has the same physical arm, connector or mounting. Compare the switch on the refrigerator before ordering.
