A transport refrigeration system, the transport refrigeration system including a container defining an enclosed volume and a refrigeration module coupled to the container. The refrigeration module is disposed to regulate the temperature of the enclosed volume and includes a compressor having a discharge port and a suction port, a condenser heat exchanger unit operatively coupled to the discharge port, an evaporator heat exchanger unit operatively coupled to the suction port, a condenser fan disposed proximate to the condenser heat exchanger unit, an evaporator fan disposed proximate to the evaporator heat exchanger unit; and a suction modulation valve coupled to the suction port. The transport refrigeration system further includes a bypass module coupled to the refrigeration module. The bypass module includes: a bypass mode switch having a normal operation position and bypass operation position; and an operational mode switch having a full cool position and fan only position. The transport refrigeration system also includes an electronic controller coupled to the bypass module. When the bypass mode switch is in the normal operation position the electronic controller regulates the operation of the refrigeration module. When the bypass mode switch is in the bypass operation position, the compressor, the condenser fan, the evaporator fan and the suction modulation valve are selectively operated by the position of the operational mode switch.
