Anyone have suggestions on the next step in debugging an original (BN4?) heater?

Here's a video of what it does: https://drive.google.com/file/d/1Ec2Q04 ... sp=sharing

Pull control out to first stop:
- blower starts running, dash light comes on

Pull control out to second stop:
- blower stops, there are a few slowing tick-tick-ticks in the back
- dash light initially goes dim, gets brighter, then goes dark

Would a lack of fuel cause the fan to turn off?
