I have a Maytag MZD2768GE refrigerator. The cold side is not staying cold. I turned the temperature all the way to 9 and still not working right. It's a little cool but my stuff ruins. Please help?

Check the coils under the unit. Most likely they are dirty and blocked. Wash them off with a spray of water from a hose nozzle and vacuum up the dirt and water with a wet-vac. DrTom4444
