My model is different but here are some ideas.
120v has some in line fuses that can be checked. Check the circuit breaker for the fridge also..
For gas listen for the click of the gas valve. If it clicks, gas should flow. Be sure all air is out of line . Turn on stove and light burner,, then try fridge again.
