Paul for Model Number PSH25PSTASV My refrigerator and freezer temps fluctuates as much as 5 degrees. I have replaced the main board and it still is doing the same thing. What can this be?
Answer Hello Paul. You will need to test the thermisters WR55X10025 and see if they are good. ThermistorTemperature Resistance77°F..................10,000 ohms36°F..................29,500 ohms0°F....................86,300 ohms You can test this with a multi-meter TJMA-DMT3. Here is a link on how to use a multi-meter. Hope this helps.http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html Read More...
