Dan Hirst for Model Number ZISB420DMA I have an older GE Monogram ZISB420DMA fridge that is not meeting temps. The technical sheet that came with the fridge says there are 4 temp sensors in the unit. 2 in the FF, 1 in Freezer, and one on Evap coil. I have found and replaced 3 of the 4, but cannot find access to the 4th on the evap cooler. I watched the video attached for this unit, but the evap cooler is within the freezer. On my unit there is a section above the fridge that has the compressor coil on one side and evap coil on the other side (I think), but that section is fully enclosed in a metal housing and does not look accessible at all. Seems like replacing this 4th temp sensor is my missing link, but can't seem to find it or access it. Please help.
Answer Dan, The evaporator is in the ceiling of the freezer compartment. You will need to remove the screws holding the panel in place where the evaporator fand motor is in order to access the evaporator. Read More... Answered by AppliancePartsPros.com | Friday, March 24, 2023
