I noticed my compressor was not turning on on my 9 year old Bosch B22CS30SNS/01. I tested the three pins on the compressor with a ohm meter and it read 6.7 ohms across any two of the three pins which indicated a good compressor. I then tested that indeed the inverter was getting 120v across the larger set of wires. Then tested the smaller low voltage input wires to the inverter from the control module located at the top of the frig and they read around 2.3v . So process of elimination says the inverter was defective. My defective inverter board is a "embraco vcc3 1156 06 f 13" the OEM replacement is a Bosch AP4397817 which cost around $300.
I purchased this GE inverter board instead of the Bosch one because it has all the same dimensions, specs, pins, etc. You just have to remove the wiring harnesses from the old inverter board and move them over to the new GE one and ground the compressor directly to the frig ground nut. I suspect my old inverter died due to heat, I can see a brown discoloration on my old inverter due to prolong heat contact with the plastic case. This new GE inverter has a big metal heat sink probably because of lessons learned from past heat related failures.
All in all very happy that I saved some money purchasing this GE inverter. I have a feeling this inverter will outlast the old one.
