Norcold Refrigerator Error Code CHECK

The CHECK lamp on the eyebrow board indicates that the Ignition Module attempted to light the LP gas burner but failed to establish or maintain a flame within the allowed trial for ignition period. The module then locks out and illuminates the red CHECK lamp as a safety response. The refrigerator will not attempt to relight the burner until the fault is cleared and the unit is reset. Common triggers include a closed gas valve, low propane, insufficient 12V supply voltage, or a faulty igniter or flame sensor.

When the CHECK lamp is active, the Ignition Module has shut down the LP gas burner and locked out further ignition attempts, so there is no active burner operation. The safety lockout is working as intended by preventing repeated unlit gas release. However, the refrigerator will not be cooling properly in LP mode while the fault is present, and the underlying cause should be diagnosed and corrected before continued use.

Repair cost depends entirely on the cause. If the fix is simply opening a gas valve or refilling a propane tank, there may be no parts cost at all. Igniter electrode replacement parts typically fall in the range of $15 to $50. A replacement Ignition Module is a more significant expense, generally in the $100 to $250 range for parts alone, with additional labor costs if a technician performs the work.

Several causes of the CHECK error are DIY-accessible. Start by verifying that the LP tank has fuel, all gas valves are fully open, and the 12V DC voltage at Power Supply terminals J-4 and J-5 is at least 10.5V. If those check out, inspecting and cleaning the igniter electrode is also within reach for a careful DIYer. Replacing the Ignition Module or flame sensor involves LP gas components and should be handled by a qualified technician if you are not comfortable working on gas appliances.

A reset clears the lockout condition and allows the Ignition Module to attempt another ignition trial, but it does not fix the underlying problem. If the root cause, such as a closed gas valve, low voltage, or defective igniter, is not corrected first, the module will fail the trial again and re-illuminate the CHECK lamp. Always diagnose and correct the fault before resetting.
