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. Most walk-in calls come down to a few causes: a dirty or blocked condenser coil, a failed evaporator or condenser fan motor, a refrigerant leak, an iced-over evaporator from a defrost fault, or a door that no longer seals. We test each one instead of guessing, so you pay for the repair the box actually needs.
