GE Side by Side

I have a GE side-by-side.
Don’t know the age, bought it used. I keep it in garage. Last night I opened it and the lights work, but no noise and it is warm. Also the temp. display inside fridge is blank and only flashes "HRS" or "HR6" on one display. Also, the displays on freezer door; water, ice, light, etc. do not work.
Can someone help me with an inexpensive repair?
Thanks

Randy
