Hi I hope you can help me determine what is going on with my refrigerator. I have an 8 year old GE Café refrigerator model CYE23TSDCSS is not cooling in fresh food or freezer sections. Following instructions in technical service guide, I got the following diagnostic test results:

• 47 FF Fan Test – 3427
• 48 FZ Fan Test – 2499
• 49 Condenser Fan Test – 1663
• 61 Compressor Relay Test – Test Executing
• 95 FF Cooling Test – 75.57
• 96 FZ Cooling Test – 75.52

I replaced the compressor inverter and had the same results.
I then replaced the mother board and it’s still not cooling in in both FF and FZ zones.
Here are my readings:

• Tested 3 leads on compressor and all have 6.8 ohms resistance
• From the main board, J9 jumper connector 7&8, specs say 2-3: New MB 2.69v - PASS
• When I disconnect control wire to inverter specs say 4-5: New MB 4.34v - PASS
• Power to the compressor is 121 VAC
• After reconnecting control wire, I feel compressor start with soft vibration
• Condenser coil is clean and condenser fan working.

Both copper lines in/out of compressor are at room temperature.
Is this indicative of a bad compressor? Or a leak in the copper lines?

Thank you,
Frank

Both copper lines in/out of compressor are at room temperature.
Is this indicative of a bad compressor? Or a leak in the copper lines?

That's a indication of a sealed system problem.

The sealed system consists of the compressor, condenser, evaporator, heat exchanger, filter/drier and refrigerant.

Common problems with a sealed system are bad compressors, refrigerant leaks, and system restrictions.

Check your owners manual warranty, some models have up to a 5 to 10 year limited warranty on the sealed system parts.

I appreciate the information Jake. I will need to contact a technician to troubleshoot and check for leaks since I don't have the proper equipment.
I will keep you posted.
Thank you, Frank
