Hakan from FL
Problem
Refrigerator will randomly fail to cool and freeze. Compressor randomly fails to start after power up.
Tools
Screwdriver, socket set, voltmeter needle nose pliers
Repair & Advice
Hard to diagnose original board. No visible signs of failure, no signs of damage. Original board obsolete and no documentation. Replaced couple of starter relays with minor temporary success. Once found the successor board it was easy order for $350 that resurrected a $1500 GE refrigerator that resides in hot Florida garage. Delivery was less than 24 hours with standard shipping.
