I noted that my refrigerator and freezer were getting warm and the appliance was running non stop. I cleaned out the bottom condenser of dust and also noted frost build up on the back freezer wall. I emptied the unit and let it defrost over night. It is now running and all is correct on temps in the freezer and fridge though I noted that it will not stop running. I turned the control knob in the freezer way down and would think I would have heard a clicking sound when the thermostat clicked off but it does not click and the unit continues to run unless I turn the knob to off. I turned the timer to the defrost mode and waited to see if it was working which it is as the unit turned back on after a period of time. I think I need the thermostat control but the guides are telling me it is a defrost control. Could you help me on this so I can get the correct part..it is listed in the guide as 5303300027. Does the freezer walls have to be removed to install this or is all of the unit contained under the panel in the freezer section...in other words...can I replace this with out a tech and/or too much problem. Thank you.
ANSWER Hello Dave. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. You do need to remove the back wall inside the freezer to access the heater and thermostat. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
