Why your Master-Bilt refrigerated display case is interior light out
Here's how interior light out typically presents on a Master-Bilt refrigerated display case: cabin or oven light failed. Bulb, socket, or door switch. Nine times out of ten it comes down to a wiring or control-board problem. Left unaddressed, food or stock can spoil within hours.
Most likely causes

- A worn or failed internal component
Known Master-Bilt refrigerated display case weak points

Quick check — and when it's not DIY
Before booking a repair, confirm the refrigerated display case has power and rule out anything obvious — a tripped breaker, an unlatched door, a blocked vent. If that doesn't fix it, if the basics check out, the fault is inside the control system or a sealed component, and diagnosing that safely takes a technician's tools and training.
