30 gh pro dialog plus chiller (Carrier)

Hi;

30 GH chiller showing fault code 40,41,47,46,103,203.

Replaced the exv motor ,pressure transaduser,sensor of both circute.
still the chilller is tripping . somebody can help please?

Hi vinod
Are you still getting the same fault codes after changing all the listed parts.
103 and 203 are HP trips on circuit 1 and 2. Have you checked the driers and are all the condenser fans running.
Blocked driers can bring up 46 & 47.

Not sure if they are right for the 30GH but for the 30GX the codes are as follows.

103 - Compressor A1 current imbalance >10%
203 - Compressor A2 current imbalance >10%
46 - Oil solenoid failure compressor A1. oil pd > 17kPa
47 - Oil solenoid failure compressor A1. oil pd > 17kPa
41 - loss of communications with analogue card
40 - loss of communications with fan card

Hello,

30GH's codes are not the same with 30 GX because the softs are different.
For help me, Your display PRO DIALOG is Black or Grey?

Hi Vinod, alarm # 46 & 47 indicate a need to check the oil solanoid valves. Sometimes they remain partly open due to some dirt.

hi did you try change the exv board ,

is it possible to take some note's of the temps and pressure wile its working???
mabey couse of an unbalance in current the comps are not functioning like they should, and therefore give an unbalanced refrig isue, whitch cause an constand tripping on security's.

just some loud thingking.
