Question about GE Monogram ZISS420NRSS 42" Built-In Side-By-Side Refrigerator (ZIS-S420NRSS, ZIS S420NRSS)
Refrigerator not cooling or freezing. We do have power. Unplugged for 1 minute and replugged. Now the display is blinking and dancing 0"s. Please advise
In most cases it is the Defrost timer circuit. One of three things the Defrost time (most likely) it allows the cooling for a 6 to 10 hour period and the defrosting for 10 to 30 minutes to remove ice buildup, ICE BUILDUP is the main problem as it restrict air flow, the cooling air circulation through the system. You see cool air only comes in the freezer side and passes through vents (pass ways) to the refrigerator side. Ice buildup in the freezer side inhibits cooling air to the refrigerator side. You think the freezer is working, but it is only cooler because there is ice in there that you can't see. The Terminator (a LIMIT switch) opens the defrost circuit if the defrost heater gets too hot (second likely) the next is the Heater which heats for those 10 to 30 minutes to melt the ice buildup (least likely) no matter the Unit you have they all have this circuit... Hope this helps, I'm Tango
