My Monogram refrigerator model ZIS420D How to get out of showroom mode?
I unplug it from power outlet for 24 hrs. then plug back in it still in showroom mode!
Answer Hello TB,
Push on both freezer and refrigerator up and down keypads simultaneously for 3 seconds. The unit will blink 0's in the display. This means in test mode. Enter freezer display to 0 and ff to 0 then hit any other pad other than up or down keypads to turn off showroom mode.
Hi my name is Victor,I have a GE Monogram refrigerator model #ZIS480D.The problem I am having is that, both the freezer & refrigerator both sides the temperture is warm. The freezer is 12 degrees & the refrigertor is 52 degrees. Every time I unplug it for awhlie & restart it, it starts working ok for a week & then it does the same thing, could it be the main board needs to be changed.
Answer Hello Victor,
It could be the main board that is at fault but you would want to check to see if you are having heavy frost build up in the freezer compartment at the evaporator coil. The evaporator coil is located at the top of the freezer compartment. You want to check continuity of the defrost heater WR51X322 and the defrost bimetal WR50X10088. If they check good then you would want to replace the control board WR55X10560 and the evaporator thermistor WR55X10025 if you are getting impacted coils. Also check your condensor coils to make sure that they are clean. 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
How do you troubleshoot the main control board when the fresh food is freezing
Answer Hello John,
You should check the dampers in the refrigerator compartment. Check to see if they have broken doors. If the doors are broken then you will have freezing in the refrigerator section. You can test the thermistors in the refrigerator at the control board. The J1 connector is the connector where the thermistors are located. You should have 2.8 to 3.5 VDC on each of the thermistor wires pin 1, 2, 3 or 4 to pin 5. Resistance values at 32 degrees would be 16.3kohms and at 50 degrees would be 10Kohms. You have 3 dampers in the unit if you have the custom cool. You have one at the top in the upper left corner of refrigerator compartment. You would also have 2 behind the custom cool section.
