What if your core sense has no lights? 12 units outside 7 of them have no power to the core sense module or rephrase 7 of them have no lights to indicate what the problem is
Yes this will help all of us in the future as this is installed more and more equipment, and we as an industry have the right training to use it to diagnose quickly. Thanks for your comment.
I have one of these on my a/c unit and there is no lights flashing or coming on this module I have that exact one. I’ve trouble shooted everything and my unit is not working. I’m thinking it has to do with this module because there’s no light of any kind coming on the device and my a/c unit will not come on
My AMANA air conditioner uses this controller, the yellow LED light is always on, but the heat pump just doesn’t work. Why? By the way，The outdoor temperature is -15 degrees Celsius now.
Has me confused as a long time designer of diagnostic systems, automotive is dirt cheap, no secondary references to compare to, more like guesswork, least military spends a couple of extra bucks with references. Now for the Coresense, downloaded the manual and studied it. Not that outside units are that complicated. Just have a 24VAC thermostat input to a contactor that switched on 240VAC to both the fan and compressor, but each instead of two wires has a third through an AC capacitor that gives a leading edge extra waveform like a two phase motor. By adding the Coresense the only difference, is that the thermostat output instead of going directly in the contactor is going into the input of the Coresense unit. So no matter how you look at it, it is only looking at the contacts of the thermostat and that is it. The output of the Coresense goes to the contactor, so what is going beyond that is any ones guess, no 240V, burnt contactor contacts, low or hi pressure sensor shot or out of tolerance, capacitor shorted, or jammed fan or compressor. Looking at just to thermostat cooling contacts, will tell the duty cycle of the compressor, but very indirectly. Any arguments against this? And since it is in series with the solenoid of the contactor it can easily be the problem of no compressor operation. Can have 24VAC in but zero VAC out.
hey dave i am just gettin into hvac and am concerned this will hurt diagnostics of hvac can you give me some feedback if all new units will employ this then we will have customers telling us what codes its pulling, this will be annoying and will this ruin the diagnostics fee we are able to charge now?

Thank you for this video. It's still very helpful 10 years later.
Thanks Jones
Thanks Daniel I will look for that, I really appreciate your ideas.
Great Video Dave would like to see more on those core sense thanks.
Thanks for the suggestion.
How do you reset it?
Great info

Just wanted to break the ice, new technology on air conditioning equipment all of will get use to seeing. Thanks for watching.

@@cjbake3238 mine also has no power either with the AC is on. Will take the multimeter to it tomorrow.
@@cjbake3238I am having this exact same issue. Were you able to troubleshoot the problem and get your AC working? Did you need a replacement Coresense
The red light of my core sense is on (no flashing) what possible can be? Gime an advise please
To reset it just remove 24V wire then put it back on ... we had power go out for 1 second which tripped device ... fixed
Great Info. Thank you.
great job.a little datalogger for current.
I will look for more info.
Is it normal for the red light to light up for a bit after a call for cooling and turn off after the compressor kicks on. Does it everytime on mine.
My Core since shows no lights on, do you think it is bad and needs to be replaced ?
Thanks, David!

Hey Dave there's also a relay Emerson Sureswitch if you have any info on that would be great Thanks. "Daniel"

DOES COME FACTORY INSTALLED ON AMANA AIR COMMAND SXC16GUC OR IS THIS AN OPTIONAL FEATURE?
My coresendor has 4 flashi g yellow lights. I have reset it, but it still doesn't work. I have sparks coming out of my contactor in the 24v connector.
bahaha wtf...shut it all off
It come installed from the factory.
Corsense are more of a headache than their worth. 😂

David Thibodeaux hahaha
Reset
Didn't help much at all.
