Check Temperature Probe(s)
4.1.8.
The Probe is Disconnected: Check the position of the probe and the connections.
The Probe Malfunctioned: Disconnect the probe and measure the resistance between the leads.
T he resistance between the leads should be between 2K and 35K Ohms. The resistance between
either lead and the ground should be infinite.
The temperature probe detected a temperature below 32° F (0°C) or above 230°F (110°C). If the
