Why Carrier Fan refrigeration unit does not start from AddVolt system nor power grid?
- EerinharrisAug 15, 2025
If the Carrier Fan refrigeration unit doesn't start from either the AddVolt system or the power grid, a possible cause is a broken fuse in the FUBO (Fuse Box). To resolve this, press the service disconnect and disconnect from the grid, then measure the continuity of all fuses in the FUBO and replace any broken fuses. If this doesn't solve the problem, check the Service Manual of the refrigeration unit.
