Defrost heater both ends has current. I check it out both leds have currents. suppose one is live side. and other is none.

GE refrigerator defrost heater not working. defrost timer is good, I found out that the current is there, but on both heater wires .

This is a very basic defrost system and very easy to diagnose. Check the defrost heater and defrost thermostat for continuity. If both check good replace the timer. The defrost thermostat needs to be below 40°F to show continuity.

Go to one of the home centers or Walmart and pick up a meter then read my last again.
