I was wondering if someone can point me in the correct direction. I am receiving 1500 alarms onoccassion. The unit never seems to lockout on this alarm but it will show up consistently. I tried replacing discharge thermistor with known to be good thermistor and the problem persisted. The literature only states that unit is overcharged or there is a problem with thermistor or input circuit on board. I set up maintenance tool for several hours and monitored discharge temperature and saturated high side temperature but was unable to catch the problem occurring. Tech support unavailable, I am awaiting training. Would the next step be leave computer on monitor mode for a day? Could it be solenoids or lev? Thank you.
