Have you ever replaced a Sentronic off a Copeland semi-hermetic compressor with a CoreSense?

It's a common issue, but there's a key difference:Sentronic is a two-wire oil failure control, whereas CoreSense Protection is a three-wire device that needs constant power.Here's what to check:Verify if the CoreSense Protection is wired correctly with three wires.Ensure it’s receiving power at all times.This simple wiring check could resolve the tripping issue and save you a lot of headaches.

I just replaced the sentronic to a coresense and have no LED at the module. Do I need a wire on terminal 2 as a neutral? 115 vac

@@LibertyMurph check the coresense manual and find the wiring schematic. You have to add a 3rd wire to power it at all times. And if you have demand cooling or a digital compressor connected you will have different wiring again. Check the manual.
