    SAT – Electric Maintenance 3. INVERTER CLEANING AND MAINTENANCE 3.1 Introduction The appearance of the inverter overheated alarm can be caused by the accumulation of dirt and lint at the inverter cooling area, making it difficult to properly ventilate the equipment. For this reason it is essential to periodically clean the inverter to maintain good ventilation and thus avoid the overheating problems.
