30GX carrier chiller

[Hamzeh jarwan]

Good afternoon every body..
I have problem with 30Gx carrier chiller
It have two circuit B & A1, A2.
There's one alarm coming..
The code number is 19, it's refer to oil transducer for circuit A2 but we changed new one,
still the same alarm coming.
Please can you help me urgently.

Thanks

I thought code 19 referred to oil temperature.

Have you checked the crankcase heater is working?
Unit will not start with cold oil.

I checked the code alarm..
19 referred to oil transducer
Also crankcase heater working..

Assuming you changed the right transducer.Check your plug connection at the board make sure wires are tight in plug also check 5vdc output at plug.
Could be cable , plug at board or maybe board but I would go for loose connection at plug at the board.
