    So I have a Utility 53’ Reefer trailer with roll up door & I was wondering if anyone knows how I can disable the sensor that shuts the unit off when the door is open. That way the unit keeps running when the door is open as well. Any input is highly appreciated. Thank you.

    The ECM needs to be plugged into and have that changed. I had a low idle switch installed on my old trailer, so I could have it run on low idle when my doors were opened. This was programmed in the ECM, and a toggle switch was installed

    Google it. There is a advanced user screen that will pull up a menu,then turn it off in there. @reeferwrencher may be able to help. It’s been a couple years since I’ve had to do it.

    Just cut the power wire and tape it off.IT sends power back to the micro to trigger the door open mode.IF you interrupt the circuit it wont come on. Good luck
