I just got my mothers Maytag side by side that she purchased last July. We got it moved and hooked up but the lights inside the Refrigerator or Freezer don't come on. What do I do?

#1. Are they running? That verifies you actually have power to them.

What have you done to verify the bulbs are good. I know it's such a small thing, and anyone would start there with new bulbs but I hate to assume. Then you check the circuit as smoothy says and make sure you have power. This should help.
