Wolf Range Error Code 800: Meat Probe Jack Shorted... | appliancefaults.com

Technical Background:

The MCU monitors the meat probe jack circuit. When a meat probe is inserted, the MCU expects a specific resistance value. Error 800 indicates the MCU detects a short circuit (very low resistance) in the meat probe jack circuit. This could be due to a faulty probe, a shorted jack, or a problem with the wiring harness.

Symptoms:

The homeowner observes an error code 800 displayed on the Wolf range control panel. The meat probe may not function correctly, or the range may not operate at all.

Possible Causes:

Shorted meat probe
Damaged meat probe jack
Wiring harness issue between the jack and the MCU
Faulty MCU (Main Control Unit)
Moisture or debris in the jack
Loose connection at the jack or MCU

Solution:

1

Disconnect power to the Wolf range at the breaker panel.
2

Locate the meat probe jack on the range. It is usually on the control panel or side panel.
3

Visually inspect the meat probe jack for any signs of damage, corrosion, or debris.
4

Disconnect the wiring harness from the meat probe jack. Use a multimeter set to ohms to check for a short circuit between the two terminals of the jack. A normal reading should be open circuit (infinite resistance).
5

Inspect the wiring harness for any signs of damage, such as frayed wires or loose connections.
6

If the jack is shorted (reading close to 0 ohms), replace the meat probe jack. If the wiring harness is damaged, repair or replace it.
7

Reconnect the wiring harness to the jack and then restore power at the breaker panel and test for proper operation.

Safety Warning:

Disconnect power to the range at the breaker panel before performing any troubleshooting. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental energization of the circuit. High voltage is present within the range; exercise extreme caution.

Prevention:

Regularly inspect the meat probe jack for debris or corrosion. Ensure the meat probe is in good condition and not damaged. Avoid using excessive force when inserting or removing the meat probe.

Expert Tip:

Some Wolf ranges have a service mode. Entering this mode may allow you to clear the error code after addressing the underlying issue, although this doesn't fix the problem it may allow you to get the range running until the parts arrive. Consult the service manual for the proper service mode entry sequence.

Frequently Asked Questions

•What is the resistance value I should expect when a properly functioning meat probe is inserted?

The resistance value will vary depending on the specific meat probe and model of Wolf range. Consult the service manual for the correct value. However, it is usually in the range of a few thousand ohms (kilo-ohms).

•Where can I purchase a replacement meat probe jack for my Wolf range?

Replacement meat probe jacks can be purchased from authorized Wolf appliance parts dealers or online retailers specializing in appliance parts. Make sure to have your model number ready to ensure you get the correct part.

•How do I access the wiring harness connected to the meat probe jack?

Access to the wiring harness usually requires removing the control panel or a side panel of the range. Consult the service manual for specific instructions on disassembling your model. Be careful not to damage any other components during disassembly.
