Hi Fellas,
First time posting on a thread, but I enjoy reading your comments and I am learning a whole lot from you fellas. Thank you all.
I serviced a thermoking smart reefer, model CRR40, year 1998, controler MP3000, uses a 7.5hp copeland discus with R134a. I keep getting error 18 (power supply phase error), and error 36 (current too high). I checked the power supply and it's ok (415v-422v, 10-14 amps @ 50hz). but when I check the up read out it's way out (565.5v and 24.5 amp on 3 leg). The unit does not shutdown and works fine otherwise.
Can someone suggest a fix without changing the relay board?
