Viking Range Error Code F32: Meat Probe Short Circuit... | appliancefaults.com

Technical Background:

The MCU monitors the resistance of the meat probe circuit. If the resistance drops below a certain threshold, indicating a short circuit, the MCU triggers the F32 error code. This is a safety feature to prevent damage to the MCU and ensure accurate temperature readings.

Symptoms:

The Viking range displays an F32 error code. The oven may not function correctly, and the meat probe function will be disabled. The error code might appear intermittently or constantly.

Possible Causes:

Faulty meat probe.
Shorted wiring harness to the meat probe receptacle.
Moisture or debris in the meat probe receptacle.
Damaged MCU (Main Control Unit).
Loose connection at the meat probe receptacle.

Solution:

1

Disconnect power to the range at the breaker panel. Verify with a multimeter that there is 0V AC at the range outlet.
2

Locate the meat probe receptacle, usually on the control panel or oven cavity wall.
3

Inspect the receptacle for visible damage, moisture, or debris. Clean with a dry cloth if necessary.
4

Using a multimeter set to ohms, test the meat probe resistance. A shorted probe will read near zero ohms. A typical good probe reads around 100-1000 ohms at room temperature.
5

If the probe is shorted, replace it with a new Viking meat probe (check the model number for compatibility).
6

If the probe tests good, inspect the wiring harness connected to the receptacle. Look for pinched, frayed, or burned wires. Use a 1/4-inch nut driver to access the wiring.
7

If the wiring is damaged, repair or replace the harness. If everything checks out, consider replacing the MCU, but only as a last resort.

Safety Warning:

Disconnect power to the range at the breaker panel before performing any troubleshooting or repairs. Lock Out / Tag Out (LOTO) procedures should always be followed. Some components may retain a high voltage even after the power is disconnected. Wear appropriate safety gear, including insulated gloves and eye protection.

Prevention:

Regularly clean the meat probe receptacle to prevent moisture and debris buildup. Avoid using excessive force when inserting or removing the meat probe. Store the meat probe properly when not in use.

Expert Tip:

Some Viking ranges have a service mode that allows you to monitor the meat probe circuit in real-time. Consult the service manual for instructions on accessing the service mode for your specific model. This can help pinpoint intermittent problems.

Frequently Asked Questions

•How do I access the Viking range service mode?

The service mode access varies depending on the model. Typically it involves a sequence of button presses on the control panel. Refer to your specific model's service manual for instructions.

•Where can I find a replacement meat probe for my Viking range?

Replacement meat probes can be purchased from authorized Viking appliance parts dealers or online retailers. Make sure to verify the part number for your specific range model to ensure compatibility.

•What is the voltage on the meat probe circuit?

The meat probe circuit is a low-voltage DC circuit, typically around 5V DC. However, always disconnect power before testing to avoid electrical shock.
