Any of you guys/girls had to troubleshoot these core sense modules? I understand what the alert LEDs indicate in conjunction with the fault code list given on a Copeland scroll fitted with this module. However I’m getting a green LED illuminate for 2 seconds (not flashing). Then it’s off for 2 seconds, then followed by both the green and red LEDs illuminating for 2 seconds, then off for 2 seconds, and then repeating the same sequence. Checked all safety’s and windings, and it won’t seem to reset even after a power cycle/reset. Starting to think either a thermistor that’s playing up in the compressor or the module itself is faulty. Any tips? Thanks guys
