A refrigeration appliance has an enclosure that defines an electronics module recess and a detachable electronics module that can be releasably retained in the recess. Tabs and tab receivers can be integrated with the electronics module and enclosure to releasably retain the electronics module in the recess. A trim piece can releasably attach to a display bezel of the electronics module by a snap-fit connection to retain the electronics module in the electronics module recess. In use, the electronics module can be selectively removed and a data acquisition device can be connected to the appliance using a data connector that is exposed by removing the electronics module.
