Viking Range Code DSI No LED: Ignition Module Shows No Power

What DSI No LED means

The Direct Spark Ignition module on Viking Professional gas and dual-fuel ranges, plus the 3 Series RVGR3305B and Designer DCCG130, has a small status LED that technicians read. DSI No LED means the LED is dark, so the module is getting no power. The burners usually will not click or light because the ignition board is not running. Wiring to the module is the first place to look. Models such as the VGSC536-6B are included.

Common causes of DSI No LED

No supply reaching the DSI module
Loose or burned wiring plug at the module
Range power cord or breaker problem
DSI module itself not powering up

✓ One safe check you can try

1. Turn every burner knob to off. 2. Check that the range is plugged in and the breaker has not tripped. 3. Reset the breaker for one minute. 4. Try one burner for a few seconds. 5. If nothing clicks, stop and call us. The module sits behind the panels. Should you smell gas at any point, get everyone out and phone the gas utility from outside.

! Why to stop there

The module is inside the range body, behind panels
Checking power on the module needs a meter on live circuits
A burner that will not light should not be forced with matches while the cause is unknown

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.

DSI No LEDDSI No LED questions

Where is the LED on my range?

It is on the ignition module inside the range, not on the front panel, so you will not see it without removing panels. We read it during a visit to learn what the module is reporting.

Can I light burners with a match?

If the burners are not lighting, that is unsafe to try on your own. If you smell gas, leave the house and call the gas utility from outside. Otherwise leave the range off until we check it.

Is the cost known before work starts?

Yes. Before we touch the range we tell you the price in writing, and once the work is done our repairs come with a 30-day workmanship warranty, so you know the cost and the cover up front.
