My refrigerator is some what old, but in good condition. I have it on the coldest settings, and it does not feel cold enough. The refrigerator started to sound as if it was working harder, this happened in the summer. Now it sounds as if its working correctly What can it be?
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. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html
Norge model NTB1914ARB drips very little from air way in the fridge rear left corner. Temperature in the fridge runs 40-45. Can you please explain how to remove control housing if control should be replaced.
If the temp in the refrigerator is too warm it will cause condensation around the air return in the refrigerator compartment. You will want to check to make sure that the evaporator fan is running at full speed and not running slowly. If the fan is running too slow then you will want to replace the evaporator fan. If the fan checks ok and the coils are not impacted with ice then the issue would be with the temp control in the refrigerator section. Make sure that there is nothing that would be right under where the bulb for the temp section is as it can cause warmer temps but if it is clear then the temp control will need to be replaced by removing 2 screws in the front of the control panel. There may also be 1 screw toward the center that would need to be removed then just roll the panel down and remove.
