If your refrigerator works on gas but it does not work on 110v AC then there is something wrong with your electrical power supply. First, check that you are getting the energy to your refrigerator. Check your circuit breakers/ fuses. If all seems well there then you will want to test the outlet your fridge is being plugged into. Using a multimeter is the best option, you are looking for a reading between 110 and 120 volts, but if a multimeter isn’t available then you can plug a fan, lamp, or another small device into the plug to test if the appliance is getting energy.
