I just finished installing an ERR Hot Box reefer Kit Upgrade but cannot get the board to power up or reprogram. I have ac power at the mini commander's green terminal power port but I don"t think the mini commander is powering up. I followed the installation instructions and connected both roller pickups to the hot side of the green power terminal. I then connected the remaining red wires to the white wire terminal HC-1 port and the black ground wire to the power ground connector. I also added an LED with the ERR recommended 1000 ohm 1/4 watt resistor on the positive LED terminal side to the LC-1 connector on the mini commander board.What am I missing or is it possible that I just got a bad ERR board? Any assistance would be most appreciated.

Just a thought my HC-1 port did not work, try HC-2 but most of all recheck all your wiring......sometimes we all need a second pair of eyes to recheck our work or sometimes walk away and come back later.

First things first, can you get the LC-1 LED to light, and can you control it using the "1" and "4" keys on the remote? Also, I use the jumper to configure instead of the soft-set feature, much easier and more positive.
Note that the LED's are polarity sensitive and REQUIRE a dropping resistor or you'll cook them. The diode is strongly recommended as well, though some people dispute my use of them.

Wm swen, anyway you can post a picture of your wiring, i will check it against my hot box reefer ERR install

I'd suggest connecting a 12V incandescent bulb on that LC1 output and then trying to program it. If you can't get the light to go on, you need to get that working before you proceed.
Did you use a meter to check if you have voltage coming in? Also, are you SURE you have the center and outside rails connected to the proper connections?
