When an air compressor overheats, the problem is typically related to factors involving irregular suction or discharge pressure. Alternately, the problem could stem from insufficient ventilation, eroded oil or any given number of issues related to the wear and tear of machine parts. The older a compressor, the more likely it is to break. In general, there are two devices that can “trip” (shut off power) on a portable generator – the Ground Fault Circuit Interrupter (GFCI) receptacles and the circuit breaker. cube with a 2-1/2 ton Concorde. My air compressor has oil coming from the pump? The outdoor unit blows air over the refrigerant coils, and if there is an obstruction or malfunction with the fan motor, it will lock up. Imagine forcing a pillow over your face. Hi!
