Carrie for Model Number LFX31925ST My refrigerator won’t go below 50 degrees. Freezer works great. I cleaned the coils in the back and made sure none of the vents were blocked. I thought I should feel air flow near the vents but there’s nothing. I tried to listen for the evaporator fan in the freezer but didn’t hear anything. No louder noises or clicks from the compressor. Thank you.
Answer Carrie, the evaporator fan will need to be tested at the main control in the back of the unit. At the connection CON6 of the main control, pin 1 (gray wire with black probe of meter) to pin 2 (blue wire with red probe) will need to be tested for 12VDC. If there is not 12VDC, then the main control has failed. If there is 12VDC, then it will need to be tested from pin 1 (black probe) to pin 3 (yellow and black wire with red probe) and the voltage should read between .1 to 4.9VDC. If the reading is not within this amount, then the fan motor has failed. The refrigerator sensor should also be checked at the main control at connection CON7 with the refrigerator unplugged. At 50°F, the resistance should read 19.5K Ohms when testing the two white wires at pins 15 to 16. The REV number for this model will be necessary when replacing parts as this can change what part is used. Read More... Answered by AppliancePartsPros.com | Tuesday, October 29, 2019
