SCS A/C removal
#3

Hi Forest: Have not pulled the unit out to check yet - have to figure that out first…
I was reading info online and found a Supco slow start capacitor but it says not to get this one - is this GOOD information?
The Supco uses a Positive Temperature Coefficient Relay (as stated on their website) not a Potential Relay. Not Good! Only use Hard Start Kits that use a true Potential Relay. The RectorSeal Kickstart (2 wire) and the 5-2-1 Compressor Saver (3 wire) hard start kits use a Potential Relay. I recommend the Kickstart (it uses 2 wires that connect to the Run Capacitor - HERM and COM). But the Compressor Saver is also good (3 wires with one connecting to the common / ground on the Contactor relay). They both work the same way - the Potential Relay detects the pickup voltage (back EMF). This causes the relay to disconnect the start capacitor when the compressor reaches about 75% speed (usually less than a second). Note: Supco does have hard start kits with a Mechanical Potential Relay (Models 3W1, 3W2, & 3W3) but they are not available on Amazon
