Viking Built-In Refrigerator Display Shr: Sensor Circuit Shorted

What Shr means

On Viking Professional 7 Series and Designer built-in refrigerators, second generation, and current 5 Series built-ins such as the VCBB5363E, VCSB5423 and VCFB5303, the temperature sensor alarm sounds and the display shows Shr. Shr means the sensor circuit is shorted. ALARM OFF silences the alarm, but if the temperature does not return to the display, you should call a technician.

Common causes of Shr

Temperature sensor shorted
Damaged sensor wire
Control input problem

✓ One safe check you can try

1. Press ALARM OFF. 2. Wait a few minutes to see whether the temperature returns. 3. Unplug for two minutes, plug in and let the unit restart. 4. Check the temperature with a thermometer. 5. If Shr stays, move perishables to a cooler and call us.

! Why to stop there

A shorted sensor cannot be seen from outside
The control may cool wrongly while Shr shows
Sensor wiring is behind the liner

Opening a panel yourself does not automatically cancel a manufacturer warranty, but it can cause accidental damage, and some manufacturers set their own service conditions. Check your warranty terms, or ask us, before deciding.

ShrShr questions

Does Shr mean the compressor failed?

No. It points to the temperature sensor, not the cooling system. But because the control cannot read the cabinet, cooling may be off, so check the temperature yourself.

Why did the alarm sound?

The control detected an invalid sensor reading and raised a sensor alarm. ALARM OFF silences it, but the cause remains until the sensor circuit is fixed.

How do you repair it?

We test the sensor, replace it if it has shorted, and confirm the display returns to a temperature. Price is written first, with a 30-day workmanship warranty.
