Viking Range Error Code 200: Power Limit Exceeded... | appliancefaults.com

Technical Background:

Error Code 200 on a Viking range typically indicates that the control board (MCU) has detected that the total power being drawn by the range's heating elements exceeds the allowable limit. The MCU monitors the current draw of each heating element and will trigger this error to prevent damage to the range's components. The MCU reads voltage from various sensors and controls the relays that switch power to the heating elements.

Symptoms:

The Viking range displays Error Code 200. The oven may not heat properly, or only some burners operate. The range might shut down unexpectedly during use. Homeowner may have tried turning the range off and on without success.

Possible Causes:

Excessive simultaneous usage of range elements.
Faulty Main Control Unit (MCU).
Incorrect oven sensor reading causing prolonged heating.
Damaged or shorted heating elements.
Loose wiring connections in the range.
Incorrect voltage supply to the range (e.g., less than 208V AC).

Solution:

1

Turn off the breaker supplying power to the Viking Range.
2

Use a multimeter to verify the voltage at the range receptacle. It should read between 208V AC and 240V AC.
3

Disconnect power. Inspect all wiring connections at the terminal block. Tighten any loose connections with a screwdriver.
4

Disconnect and inspect the oven sensor. Use a multimeter to check its resistance. Compare the reading to the manufacturer's specifications. A faulty sensor may need replacing.
5

Disconnect and inspect each heating element individually for signs of damage like blistering or breaks. Test each element for continuity with a multimeter.
6

Check the amperage draw of each element with an ammeter while the unit is energized. Compare the readings to the manufacturer's specifications.
7

If all other components are good, the Main Control Unit (MCU) may be faulty and require replacement. This step is best left to a qualified technician.

Safety Warning:

Disconnect power to the range at the breaker panel before performing any troubleshooting or repairs. Lock Out / Tag Out (LOTO) procedures must be followed. High voltage is present when the range is energized.

Prevention:

Avoid using all burners and the oven simultaneously for extended periods. Schedule annual licensed technician maintenance to inspect wiring and heating elements.

Expert Tip:

Some Viking ranges have a service mode accessible by pressing and holding specific buttons during power-up. This mode allows for diagnostics and calibration. Consult the service manual for the correct key sequence for your specific model.

Frequently Asked Questions

•What is the typical resistance range for a Viking range oven sensor at room temperature?

The resistance range for a Viking range oven sensor at room temperature (approximately 70°F) is typically between 1000 and 1100 ohms. Consult the service manual for precise values for your specific model.

•How do I safely measure the amperage draw of a heating element in the range?

Use a clamp meter. Clamp the meter around one of the wires feeding the heating element. Set the meter to measure AC amps. Turn on the element and read the amperage. Ensure you are using a meter rated for the voltage and amperage of the range and follow all safety precautions.

•Where can I find the service manual for my specific Viking range model?

You can typically find the service manual on the Viking website under the 'Support' or 'Resources' section. Alternatively, search online using your model number followed by 'service manual'. Third-party appliance part websites may also offer service manuals for download.
