Where is the manufacture date code on a CR453CB3HBAFG (B1360321) contactor for Goodman Air Conditioning part? The part is manufactured by GE

You will probably have to get that from a parts house that sells them,, most contactors are interchangeable,, about all the same except for single pole or a double pole

wmproop hit it on the head. A contactor is a contactor. If yours is a 30va single pole contactor with a 24v coil any contactor with the same rating will work, the same for a 2 pole contactor. Get them from any hvac supply company it may run from $12 to $20.
