You have to remove oil and refrigerant.

If your machine has isolation valves, You can transfer refrigerent to the condenser to change this sensor.

Why don't they put that thing in a well?

You can put the charge in the condensor with an isolation valve on the dicharge of the compressor and liquid lines, you should have flow through the cooler while you are doing this also.{ to keep from freezing a tube. Drain the oil and good to go, also make sure the oil heater is disconnected before oil is drained. Good luck!

we decide with the owner remove complete charge of refrigerant also change the oil put new sensor and filters and again put the unit on service.
thanks all for the support opinions and thoughs

Oil sump temp sensor shows code 267. Fail sensor. -40*f.
When I compare my resistance and voltage drop readings against the Carrier manual it tells me all is good. I've measured at the sensor and at the pic 2 panel. Reset the alarm. A few hours later the alarm comes back. Anyone have this experience?

pump the charge over to about 1/2 psi and drain the oil level below the sensor and be PDQ
