Christine H Glassboro , NJ April 01, 2020 Appliance: Model MAYTAG MBF2953YBF4 Freezer was too cold, 18 degrees. Ice building up in freezer (freezer on bottom) then defrosting and leaking water into the floor. Replaced electronic control board which did not change anything. Replaced freezer temperature sensor which solved the problem. Freezer stays within 0 to -5 and no more ice buildup and leaking drain pan. Horray! 1 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
