Mark Y Chesaning , MI February 02, 2020 Appliance: Maytag Refrigerator MBF1956KEQ11 Maytag Refrigerator Mbf1956keq11: Fridge was warm and freezer too cold. How to replace Thermistor Kit. Replaced the Control Board for the 2nd time, but also replaced the fridge thermistor, just to be safe. The 1st time was less than a year ago, but was not an OEM part. This time we replaced it with the OEM part, so hopefully will last longer. Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
