LI OP means the high-temperature limit switch on the boiler has opened. That's the safety device the Norcold recall added. The High Temp Switch 637360 is the switch for the 1210 and 2118 (2-3 week lead time). Keep in mind that it trips because the boiler overheated, which usually means the cooling unit is failing. Replacing the switch alone may not fix it. See our LI OP article. For recall questions, contact Norcold directly. The 1210/2118 are discontinued. Norcold's replacement is the N15DCSS for the 1210 and the N20DCSS for the 2118. See our Norcold replacement guide.
