I have a Vulcan Model # SG36L77R Natural gas 36 in. stove with Snorkel convection oven. My question is? With the blower plugged in, and display power switch turned to on. I get a red power on light but no fan starts. Is this normal? I have no gas line hooked up at all, no pilots lit. Just wondering if the blower needs the oven to be lit and heating up. I just bought and was just seeing if blower would come on
