Viking Sensor Microwave Message "ERROR": vapor not detected or entry out of range

What ERROR means

On Viking sensor microwaves such as the VMOR205SS and RVMHC330SS convection microwave hoods, and the VMDD5306SS and VMOC506SS, ERROR on the display has several meanings. If the sensor does not detect vapor properly during sensor cooking, ERROR appears and the oven turns off. It also appears for an invalid clock entry, or for amounts or weights outside the allowed range. An open or shorted humidity sensor can also cause it.

Common causes of ERROR

Food covered too tightly, too small, or in the wrong sensor category so no vapor is detected
Invalid clock entry or amount or weight outside the allowed range
Door opened during the sensor phase
Humidity sensor open or shorted

✓ One safe check you can try

1. Press Stop/Clear and check the entry you made; re-enter the clock time or food weight within the range the oven accepts. 2. For sensor cooking, use a microwave-safe container, loosen the cover so steam can escape, and choose the right food category. 3. Keep the door closed during the sensor phase. 4. If ERROR returns on every sensor program, call us.

! Why to stop there

Most ERROR messages come from entry or cooking set-up and need no repair
A sensor that fails on every sensor program is a different story

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.

ERRORERROR questions

Does ERROR always mean the microwave is broken?

No. It often just says the sensor did not detect vapor or the entry was out of range. Re-enter the setting and adjust the covering before assuming a repair.

Why does it appear on sensor cooking only?

Sensor cooking relies on detecting steam from the food. If the food is covered too tightly or the portion is too small, no vapor is detected and the oven stops.

When is a service call needed?

If ERROR appears on every sensor program even with the right food, container and entry, the humidity sensor may be open or shorted and needs to be tested.
