Norcold N842IM 'No CO' Error Fix - Complete Propane Troubleshooting Guide
Apparently everyone has a different theory about my Norcold N842IM's 'No CO' error—my neighbor swears the propane tank's empty, the RV dealer blames the thermocouple, and YouTube insists it's just dirty burners. The fridge works absolutely perfectly when we're plugged into shore power and running on AC - no problems whatsoever with cooling performance or any error codes.
The real problem starts when we disconnect from shore power and head out on the road. The refrigerator switches over to propane mode without any issues initially, and everything seems to be working normally for the first several hours. However, after approximately 8-9 hours of running on propane, I consistently get an alarm and a 'no CO' error code displayed. I've been turning the refrigerator off for about an hour (though I'm not sure if that's the right amount of time), and when I restart it, it runs fine for another 8-9 hour cycle before the same error occurs again.
I'm wondering what could be causing this specific 'no CO' error to appear after this consistent timeframe when running on propane. Is this related to combustion problems, ventilation issues, or something with the propane system components? I'd really appreciate some guidance on what I should be checking and how to properly troubleshoot this recurring problem. …more
