Is your refrigerator doing one of the following?
- N610, N611, N810, N811
- front light flashing 6 times
- N400, N410, N412, N500, N510, N512, N621, N622, N821, N822
- front display showing "O"
- N641, N642, NX641, NXA641, N841, N842, NX841, NXA841, 1200, 1210, 1211, 2117, 2118

These codes appear when either your high temperature limit switch has been tripped or there has been a break in the connection at LIMIT IN and LIMIT OUT on the rear power board. The first thing we would recommend you do is to take a look at your power board by removing the power board cover. Look at LIMIT IN and LIMIT OUT on that board. If there are wires attached, they should lead you to a thermal switch. This switch is designed to trip power to the refrigerator if the temperature at the flu exceeds safe parameters. This is a safety precaution designed to prevent a fire. We do not recommend resetting the thermal switch until it is clear as to why it went off.
If you have a model refrigerator without a thermal switch, meaning there are no wires connected to the LIMIT IN and LIMIT OUT, you should have a small jumper wire going across that terminal. For those individuals, we recommend paying attention to how level you are when you camp. Cooling unit failures are caused from overheating which is often times just a result of accidentally running it off-level for extended periods of time.
For those of you with a thermal switch that has NOT gone off and yet you're still getting one of the codes above, this could be a problem with either your refrigerator power board or with dirty voltage being supplied to the refrigerator.
