Liebherr’s older commercial reach-in coolers use a mechanical thermostat dial, numbered 1 through 7, instead of a digital display — there’s no electronic error code to read, so diagnosis relies on checking the dial setting and the cooling parts directly.
A thermostat turned all the way down to 0 switches cooling off while leaving the unit powered, which is easy to mistake for an electrical problem since nothing on the exterior indicates why it’s not cooling. A dial that’s simply drifted from its original setting, and a condenser overdue for its annual cleaning, are the other common calls — neither one comes with any code to flag it ahead of time.
