Viking Induction Rangetop Code 5 Flashes: power device temperature sensor malfunction

What 5 flashes (with brief interval) means

A five-flash pattern with a brief interval on Viking induction rangetops such as the VIRT301 and VCRT301 means the temperature sensor on the power device is malfunctioning. The sensor lets the unit watch how hot the electronics get. Without a good reading the unit cannot protect itself, so it may limit or stop heating. The pattern tells us to look at the sensor and its connection first.

Common causes of 5 flashes (with brief interval)

A power device temperature sensor that reads wrong or has failed
A loose or damaged sensor wire or plug
A control board input that no longer reads the sensor

✓ One safe check you can try

1. Switch all zones off and let the rangetop cool for 30 minutes. 2. Turn the breaker off for a full minute, then restore power. 3. Try a zone at medium power with a flat, magnetic pan. 4. If five flashes return, stop using the rangetop. 5. Call us and give us the full model number.

! Why to stop there

The sensor sits on the power device inside the unit, out of reach for owners
The sensor and the board need testing to tell which one is wrong
Running without a working sensor removes a safety check

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.

What does the sensor do?

It watches the temperature of the power electronics so the unit can reduce power before heat becomes a problem. When it malfunctions, the unit cannot judge safely.

Is five flashes the same as overheating?

No. One flash is the overheating pattern. Five flashes means the sensor that measures that heat is not reporting correctly, so the cause is the sensor path.

How is it repaired?

We test the sensor and its wiring, replace only the part that fails, and quote the price in writing first. Repairs carry a 30-day workmanship warranty from the day of the visit.
