    Carrier 30 RBF 130 - Loss of communications failure ( Houston Flood)

    I have a carrier 30 RBF that I am chasing a weird alarm , loss of communication when leaving water temp hits about 49.5 the machine just shuts down . The chiller was in the recent Houston flood . Water level was half way up to the compressor contactors on the picker head of the scroll compressor . The first alarm we got was oil temp . We found all compressor motor protector modules were bad , 6 in all . After we replaced everything good for a few days . We do have a grounded A1 compressor but the barker is turned off . No chasing a losss of communication failure when water gets to about 49.5 the entire machine shuts down .

    Verify all electrical connections are moisture free and no corrosion is present . It maybe necessary to replace / re-splice wire connections . It may be necessary to purge nitrogen through the conduit to verify there is no standing moisture present . ( Place paper towel on opposite end to detect moisture . ) The procedure is tedious and time consuming .

    Thanks . This is going to be a good one especially with the machine being replaced a little over a year / a half ago .

    Any electrical component that got wet needs to be replaced. As stated above, may need to resplice any corroded terminals. On the grounded compressor with the breaker off, do you have the compressor disabled in the controller? If not, the circuit will trip.
