Control Display Panel Fault Table

The refrigerator's electronic control provides "fault codes" for a variety of fault conditions.

For example, if the thermal switch located on the canister just above the burner box reaches an

abnormally high temperature, the thermal switch "opens" and the control display panel lights up the

following indicators: CHECK, AUTO, GAS, AC, DC and they remain ON when the control is powered ON.

In addition, all the power source outputs (the AC relay and the GAS valve relay output) are all disabled.

Another example, if the refrigerator is in GAS mode and the burner fails to ignite in the 45 seconds

allowed, the control display panel turns on the GAS indicator, it flashes the CHECK indicator, and the

beeper sounds a beep lasting 240ms.

A third example, if the door is left open for longer than 2 minutes, the CHECK indicator flashes and the

beeper sounds a very short beep approximately every 2 seconds.

The table below provides a complete listing of all of these fault codes.
