When to call
If the problem comes back, product is above safe temperature, or the fix involves refrigerant, gas or electrical parts, call a technician. Display cases fail from dirty coils, failed fans, lighting and anti-sweat heater problems, defrost faults and refrigerant leaks. Fogged or sweating glass and warm product are the signs customers notice first.
