1Nolaguy I have two Whirlpool MBR2258XES4 refrigerator on top freezer on bottom that were purchased at the same time. They have both stopped cooling in the refrigerator but the freezers work fine. I took down one unit finding the evaporator coil frozen over. After defrosting all appears to be working fine. On the second unit I decided to check the CB diagnostics first to see if It will tell me more specifically what the issue(s) are. I held in the light switch and pressed the freezer + button three times. Instead of the displays reading "S" and "E" it reads "S" and "H" respectively. Pressing the refrigerator + button does not display the software version, just the "H". Please advise what the "H" means and what further steps are recommended to diagnose the cause of my problem. Strange the two identical units, purchased at the same time would exhibit the same problem at the same time.
Answer 1nolaguy, This issue may be shorted defrost heater and will want to test the heater for being faulty. Read More... Answered by AppliancePartsPros.com | Friday, January 4, 2019
