Viking Beverage Center Ice Maker LED 2 Blinks, Pause, 3 Blinks: Both Thermistors Out of Range

What Diagnostic LED: 2+3 blinks means

On Viking undercounter beverage centers with an ice maker, such as the VURI1401D, DURI140D and DFRI1401D, two blinks, a pause and three blinks on the diagnostic LED mean both the defrost thermistor and the evaporator thermistor are out of range. With both sensors off, the control has little to work with, so cooling and ice making may be unreliable or stop.

Common causes of Diagnostic LED: 2+3 blinks

Both thermistors out of range
Shared wiring or connector problem
Control board input problem

✓ One safe check you can try

1. Check power and the temperature setting. 2. Unplug the unit for one minute and restart it. 3. Keep the door closed. 4. Move ice or drinks you need to keep cold. 5. If the pattern returns, call us. Do not remove the grille cover.

! Why to stop there

Two sensors at once points to wiring or the control
Meter tests are needed
Cooling may stop altogether

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.

Diagnostic LED: 2+3 blinksDiagnostic LED: 2+3 blinks questions

Why do both sensors fail together?

They may share a connector or the control may be reading both wrongly. That is why we test the wiring and the board as well as the sensors.

Is the beverage center still cooling?

It may be erratic. Check drink temperatures and move items you cannot risk. Two blinks, a pause, then three blinks is the pattern, so watch a few cycles to be sure.
