Some models feature a meat probe that is used to monitor the internal temperature of the food during

cooking. The meat probe is a RTD (Resistance Temperature Device) similar to the oven temperature

sensor found in ranges with electronic oven controls. As the temperature of the meat probe increases

the resistance decreases. The E O C monitors this resistance whenever the probe is inserted into the

receptacle and uses this information to determine when the food has reached the target temperature.

The components of the meat probe

feature are: Probe assembly (Fig 1 )

and the receptacle assembly which

includes the wire harness (Fig 2 ).

Possible failures of the meat probe feature are:

• Loose wire or harness connection.

• Defective receptacle and wiring harness.

To troubleshoot the meat probe feature first test the probe itself

by using an ohm meter to measure resistance. Place one of the

meter leads on the very tip of the probe plug and the other lead

on the adjacent short segment as indicated in the photo.

The resistance will vary depending on the actual temperature of

the probe. At a room temperature of 77 degrees the resistance

will measure approximately 46,000 ohms.

To test the accuracy of the probe place the metal wand end into a container of water that has a

temperature of 120 degrees Fahrenheit and measure the resistance. At 120 degrees the resistance

should be between 17,860 ohms and 19,740 ohms. If the resistance is incorrect replace the probe.

If the probe resistance is correct plug the probe into the receptacle inside the oven and disconnect the

probe harness connector from the E O C connection P 18.

Measure the resistance between the two

wires in the harness plug. If the resistance is

approximately equal to the resistance of the

probe then the harness and receptacle circuit

are good.

If the resistance is significantly higher or lower than that of the probe then the receptacle and wiring

harness should be replaced. The receptacle and wiring harness are replaced as an assembly.

If the probe, receptacle and harness are good but the probe feature does not work the failure is in the

E O C and it must be replaced.
