I would like to ask the resistance of sensor when we pull it out from the unit.
Answer Hello Dan. At room temperature(75 dgrs F.), your thermistor should read 5.1k ohms.
A few days ago our refrigerator started making a humming noise.. And noticed some ice build up.. Would like to know the cause... Thank you
It sounds like you may have some type of defrost failure. You will want to pull the rear cover of the section where you are seeing ice build up and check to make sure that the evaporator is not impacted with ice. If it is then you will need to check the defrost sensors and heater to ensure them being good. If they are bad then replace them. If they are good then you w ill need to replace the control board.
The freezer is working and the fridge is not. The coils are frozen in the fridge. Please help.
Answer Hello Sayed. Based on the information you provided, you will need to order and replace the evaporator DA96-00020Q on the unit.
Hello, I have replaced the main control board, both temperature sensors in the freezer and I'm having the same issue. The unit will get to the proper temp an will not start back up without being unplugged and plugged back in. We notice that there was ice on the coils in he freezer ad had to use a hair dryer to thaw the ice. It will run fine until the ice forms again! What could this be?
Thank You in advance for your help.
Answer Hello Quincy. 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
