Limit activations serve as a persistent, protective interruption of heating in the oven chamber.
Always identify and correct
the cause of an oven limit activation before restoring heating.
The red Alarm Light on the Control Panel illuminates steadily during an oven limit cutoff.
Note:
The oven chamber
is not heating
in the example above. The power bar (PWR) indicates the
oven controller is calling for power to the heating elements. However, the active Oven Limit system is
routing power away from the elements.
Possible Limit Activation Causes
•
Launching a heating profile with a temperature setpoint near to or exceeding the current
Oven Limit setting.
•
An external temperature source or a heat source in the oven chamber is pushing
the oven temperature to or above the Limit setting.
•
The temperature controller circuitry or sensor probe has failed, allowing
uncontrolled heating in the chamber to meet or exceed the Oven Limit setting.
If you suspect a hardware failure or an ignition even in the chamber,
turn off the oven and wait for the
oven to cool to room temperature before backfilling the chamber.

Oven Limit Heating Cutoff Active
In this example, the chamber temperature
exceeds both the Oven Limit Setting and the
Temperature Setpoint.
Note: Tapping Clear or Dismiss on the Alert
Window does not end the Oven Limit. It only
closes the window.
