(behind the 3” plug button).
The ONNA uses timed-off defrost as its primary defrost method. Access to the termination control probe can be gained 
by simply removing the plastic plug in the flu-panel.
The temperature control probe is located behind the 3” plug button in the top flue panel (see diagram). Both of these 
probes are wired to the case controller that is mounted on the top of the case.
