Hi gentlemen. I'm Dave, and I'm always wrong too. It's been 33 years since I was not wrong.

For your fridge...
You should hear the "snick-snick-snick-snick whoosh" when the pilot lights and the fridge starts. It will turn off on its own when it hits the configured temp, and then snick-snick-snick-snick whoosh when it cycles back on again.
(...unless I'm wrong)
