If the outdoor unit of a central air conditioner fails to start, the air conditioner cannot operate normally, which may disrupt our daily lives. So, what could be the cause of the outdoor unit not starting? Let's find out together.
Why isn't the central air conditioner's outdoor unit starting up?
Reason one: It's a power voltage issue. Simply check if the power source is functioning properly, ensuring that the voltage is either present or reaches the rated voltage. If the voltage is too low, inspect whether the indoor and outdoor units are correctly connected, if the wires are worn, and if the indoor mainboard connections are accurate.
Reason two: Extended lack of air conditioning maintenance can lead to rust and aging, which, in severe cases, can cause the outdoor unit of the air conditioner to malfunction.
Reason three: Being an outdoor environment, both excessively high and low temperatures can affect the outdoor unit's inability to operate. Reason four: The condenser has malfunctioned. Outdoor condensers have a self-protection system; if the central air conditioning is not regularly cleaned, it will activate self-protection, leading to the outdoor unit of the air conditioner not functioning.
