freezer and refrig not frozen or cold

Last night freezer started dripping water out of ice maker. Realized it was not cold. Neither was the refrigarater side. Pulled front grill off, it was clean from front. Pulled back panel off, there was dust back there. Cleaned out and checked that compressor was running. Don’t know what else to check. Turning down coolness did not help all night. Did not see anything like water, or ice build up in bottom of refrig panel. Any help in what to do next will be appreciated.
