When it comes to overheating in a motor air cooler, one of the initial diagnostic methods is to check the air intake. If the air intake is blocked by dust, debris, or other obstructions, the amount of air flowing through the cooler will be reduced, causing overheating. For example, in an industrial environment where there is a lot of dust, the filters of the motor air cooler may get clogged quickly. To solve this problem, cleaning the air intake and filters regularly is necessary. Another possible cause of overheating could be a malfunctioning fan. If the fan is not rotating at the correct speed or has stopped working altogether, the heat dissipation will be affected. In such a case, checking the fan motor and its electrical connections is crucial. If the fan motor is faulty, it may need to be repaired or replaced.
