Building systems that lasted decades the company was solely focused on putting out appliances that make a name for themselves. Over the past decades, the company has gained a lot of achievements making them one of the few that have created a solid standing around the world.
Settled in more than 106 countries, Carrier is now available in six continents. Offering a wide range of appliances while keeping its main focus on its original air conditioning and heating system. These include air conditioning and heating solutions for residential and commercial buildings. One of the most promising appliances the company offers is its chillers which ensure smooth workings in various conditions.
When facing an error code we suggest you grab a pen and paper to note down the code rather than pressing various buttons on your Carrier Chiller. This way you will not risk damaging your appliance any further and will be able to find out the exact issue using the common error code list for Carrier Chiller error codes listed below. Once you nail down the issue you can easily call in a professional, or fix the issue yourself.

The PRO-DIALOG Plus control system has many fault tracing aid functions. The local interface and its various menus give access to all unit operating conditions. The test function makes it possible to run a quick test of all devices on the unit. If an operating fault is detected, an alarm is activated and an alarm code is stored in the Alarm menu.
Diagnostics and Troubleshooting
Resetting Alarm Codes
When the cause of the alarm has been corrected the alarm can be reset, depending on the type, either automatically on return to normal, or manually when action has been taken on the unit. Alarms can be reset even if the unit is running. This means that an alarm can be reset without stopping the machine. In the event of a power supply interrupt, the unit restarts automatically without the need for an external com- mand. However, any faults active when the supply is inter- rupted are saved and may in certain cases prevent a circuit or a unit from restarting. A manual reset must be run from the main interface using the following procedure:

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?

Re: 30 gh pro dialog plus chiller (Carrier)
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.

Re: 30 gh pro dialog plus chiller (Carrier)
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 cardBrit

Re: 30 gh pro dialog plus chiller (Carrier)
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?

Re: 30 gh pro dialog plus chiller (Carrier)
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 ,

Re: 30 gh pro dialog plus chiller (Carrier)
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.
