Common causes
If the mini-split turns on but the indoor unit fan does not spin, the problem may be related to dirt buildup blocking the blower wheel, a faulty fan motor, a capacitor when the particular model uses one, electrical connections, sensors or a fault in the electronic control board. Some systems may also display an error code related to the fault.
When to request service
Confirm that the system is set to an operating mode that requires the fan to run and check whether an error code is displayed. If the indoor fan remains stopped, you hear a humming sound, notice a burning smell or the system does not distribute air, turn off the mini-split and request professional diagnosis. Do not insert objects into the blower, attempt to spin it while the system has electrical power or handle electrical components.
How much can this repair cost?
Basic air conditioning repairs or initial work typically range from $650–$1,200 MXN. Repairs requiring parts or more extensive work can range from $1,200–$5,500+ MXN.
