got warm refrigerator section and ice buildup on back at the freezer on my Jenn Air Refrigerator Model/Serial JFC2087HRS/10208490EX , replaced the control board Dec 2020.
using the part was ordered from Amazon
amazon.com/gp/product/B07CWG3T5Y
found refrigerator section not cold anymore since last week. and ice buildup on back at the freezer, but not too much yet.
let freezer and refrigerator door open for a day, all ice melt/drained,
then run service test at room temperature
Service Test 1: Defrost Thermostat & Defrost Circuit Test
freezer indicator= 1; Refrigerator indicator either blank or "O", at toggling Refrigerator Up button, i.e, the defrost thermostat Open
Service Test 2: Compressor/Condenser Fan Test
freezer indicator= 2; Refrigerator indicator either "O" or "F", at toggling Refrigerator
Up button, but no effect on Compressor/Condenser Fan, no sure about compressor
but the fan is keeping running at the toggle between "O"/"F".
Service Test 3: Evaporator/Freezer Fan Test
freezer indicator= 3; Refrigerator indicator either "O" or "F", at toggling Refrigerator
Up button, and I can hear the fan is on and off accordingly, i.e. the test passed
Service Test 4:Fresh Food thermistor Test
freezer indicator= 4; Refrigerator indicator either "blank" or "P", at toggling Refrigerator Up button,
Service Test 5:Freezer thermistor Test
freezer indicator= 5; Refrigerator indicator either "blank" or "P", at toggling Refrigerator Up button,
Service Test 6:Open Damper Test
freezer indicator= 6; Refrigerator indicator either "O" or "C", at toggling Refrigerator Up button, I can hear the noise sound at the toggling.
after set Damper open, go back to Service Test 3: Evaporator/Freezer Fan Test, air blows into refrigerator section.
afterwards, closed all the doors and let it run overnight w/ default setting 4 for both freezer and refrigerator
then run service test at cold temperature
Service Test 1: Defrost Thermostat & Defrost Circuit Test
freezer indicator= 1; Refrigerator indicator either blank or "S", at toggling Refrigerator Up button, i.e, the defrost thermostat shorted (closed)
...
Service Test 6:Open Damper Test
freezer indicator= 6; Refrigerator indicator either "O" or "C", at toggling Refrigerator Up button, I can hear the noise sound at the toggling.
after set Damper open, go back to Service Test 3: Evaporator/Freezer Fan Test, air blows into refrigerator section.
look like all hard-ware test ok, Should I go ahead to change the control board ?
Thanks
