David H Colorado Springs , CO September 19, 2014 Appliance: Model MAYTAG MZD2766GEB Cooling dropped off in the fridge but the freezer was still working then freezer temps dropped Thawed out the evap/heat exchanger assembly, replaced the overload/relay kit as well as the defrost control board and the fridge was back in business, everything working fine. I'm kicking myself for not ordering these parts earlier. there was a clicking sound coming from the compressor that I ignored which was a huge mistake. 26 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
