The refrigerator lights were on so I know power was present. I have had trouble with GE circuit boards before so I ordered the main board and the panel display board. They came in from Appliance Parts Pros as promised. Installed the panel display, took about 5 minutes. Then removed the back cover and installed the main board. Plugged the unit in and the panel was now flashing 2 0’s. Moved the freezer to 5 and the compressor started and ran. Moved the refrigerator adjustment to 5 also. Everything went back to normal. Fridge is cooling perfectly. Took total of an hour because I vacuumed the condenser coils while the fridge was pulled away from the wall. Very happy, can get another 10 years running hopefully.
