Good morning everyone, I am working on this carrier chiller . Keep getting a code 61( no cooler flow) the chiller uses glycol for the condenser side and building water for the evaporator side. Both the glycol and domestic water pumps are running, and the pressure looks good on them. I thought it was an issue in the glycol section, but I noticed out of the four compressors the chiller will stay running with one compressor if a second compressor decides to come on it will go into the alarm a minute after it started. Sidenote, when my guys arrive to this site it was only running on one compressor in circuit A. circuit B compressors 1&2 were off because that circuit was flat due to a leak. Once the repair was complete it was started up and that’s when we noticed the alarm and issues. But if you disable circuit B compressors 1 and 2, it will only operate compressor one in circuit A you had to disable compressor in circuit A for it to stay running. Any help is much appreciated.
