Will not go in to defrost. What control the defrost cycle on this model mbr22566kes serial 10664475je

Lupe R for Model Number maytag mbr22566kes

ANSWER Lupe, There are 3 components to the defrost circuit on this unit, the control board W10503278, the defrost heater 67001794 and the defrost thermostat 67003426. You will want to pull the rear cover off the wall and check the defrost thermostat and defrost heater for continuity. If there is no continuity then you will want to replace the part without continuity. If both have continuity then you will need to replace the control board. You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
