GE Profile Precision Cooking Probe Temperature... | appliancefaults.com

Technical Background:

MCU Logic and Voltage Paths

The GE Profile range utilizes a microcontroller unit (MCU) on the main control board to interpret the resistance value of the temperature probe. This resistance varies with temperature and is converted to a temperature reading displayed on the control panel. A small voltage (typically 5V DC) is supplied to the probe circuit. Any interruptions or deviations in this circuit will cause inaccurate readings.

Symptoms:

US Homeowner Observations

The oven displays inaccurate internal food temperatures. Food is either overcooked or undercooked despite using the precision cooking probe. The temperature reading fluctuates erratically. Error messages related to the temperature probe may appear on the display.

Possible Causes:

Faulty temperature probe
Incorrect probe placement within the food
Calibration issues with the oven's control board
Wiring harness damage or loose connections
Oven temperature sensor malfunction (primary sensor affecting probe reading)
Control board failure

Solution:

1

Disconnect power to the GE Profile range at the breaker panel.
2

Locate the temperature probe receptacle, usually on the front of the range.
3

Visually inspect the probe and receptacle for damage or corrosion.
4

Using a multimeter, test the probe's resistance. Refer to the GE Profile service manual for the correct resistance range at room temperature (typically around 1080 ohms at 77°F). Replace if out of spec.
5

Check the wiring harness connecting the probe receptacle to the main control board for continuity and shorts.
6

If the wiring and probe are good, the control board may require replacement or recalibration. Refer to the service manual.
7

Restore power to the range and test the probe's accuracy.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed. High voltage components are present inside the range; exercise caution.

Prevention:

• Avoid bending or crimping the temperature probe cable.

• Clean the probe after each use with a damp cloth.

• Store the probe in a safe place to prevent damage.

• Periodically check probe accuracy with a known-accurate thermometer.

Expert Tip:

GE Profile ranges often have a service mode that allows you to calibrate the temperature probe. Refer to the service manual or online resources for the specific procedure for your model. Usually it involves pressing a specific sequence of buttons on the control panel.

Frequently Asked Questions

•What resistance value should I expect from a working temperature probe at room temperature?

Typically around 1080 ohms at 77°F, but always consult the specific service manual for your GE Profile model for the precise value.

•How do I access the main control board on my GE Profile range?

Usually, you'll need to remove the back panel of the range. Be sure to disconnect power first. Screws will hold the panel in place, often requiring a 1/4-inch nut driver.

•Where can I find a replacement temperature probe for my GE Profile range?

You can purchase replacement probes from appliance parts retailers, both online and in brick-and-mortar stores. Be sure to have your range's model number handy to ensure you get the correct part.
