"no CO" means the fridge has detected that it isn't cooling properly. It usually points to the cooling unit, the heat source (the burner on LP), or poor ventilation, and a new board rarely fixes it. If it only happens on LP, check the burner, flue and baffle, and the LP pressure first. Read our post on Norcold no CO and our guide on RV refrigerator not cooling. Our tech support service can help you pin it down. If you have any questions, just reach out at info@rvfridgeguys.com or call us at 800-712-8822.
