The controller (current relay) burned up

1. Unhooked a retaining wire that secures the controller to the compressor terminal box. 2. removed destroyed part. 3. Got the model and serial numbers and got online. 4. Ordered part 5. Waited a couple of weeks to get part 6. Found that the manufacturer had daisy chained a bunch of components together with some funny deep socket plugs that by themselves are not routinely found so rather than buy a laundry list of unnecessary parts to get the aforementioned plus and make my customer wait a couple of more weeks I chose to connect the wires to a couple of high temperature female stainless steel quick connectors and feed the wires directly into the controller. Fortunately the controller had the polarity marked on the housing. (L for Line was the hot lead and C was for common the neutral lead) Failure to follow proper polarity will damage the part and could kill the compressors's start wimding.
