The control method for an air conditioner electronic expansion valve comprises the following steps: acquiring the exhaust temperature of a compressor after an air conditioner operates for a first preset duration and the exhaust temperature of the compressor after the air conditioner operates for a second preset duration; calculating a temperature difference between the exhaust temperature of a compressor after an air conditioner operates for a first preset duration and the exhaust temperature of the compressor after the air conditioner operates for a second preset duration; and when the temperature difference is greater than a preset temperature difference, controlling an increase in the current degree of opening of the electronic expansion valve of the air conditioner. The present application solves the problem that the electronic expansion valve is improperly controlled, and the air conditioner still controlling the electronic expansion valve according to an original control method, which results in abnormal exhaust temperature of the compressor and even abnormal operation of the entire air conditioner.
