Check Valve - Cabin Condenser (Heat Pump) (Remove and Replace)
Correction code 18400902 0.42 NOTE: Unless otherwise explicitly stated in the procedure, the above correction code and FRT reflect all of the work required to perform this procedure, including the linked procedures. Do not stack correction codes unless explicitly told to do so.NOTE: See Flat Rate Times to learn more about FRTs and how they are created. To provide feedback on FRT values, email LaborTimeFeedback@tesla.com. NOTE: See Personal Protection to make sure wearing proper PPE when performing the below procedure.
- 2023-04-04: Updated A/C oil type to be used with reference to Fluids and Capacities for A/C oil specifications.
- 2024-01-23: Updated the way of performing the routines from using Toolbox to using the touchscreen.
Note
This procedure requires the A/C
Refrigerant (Recovery and Recharge) procedure to be performed. If not already
automatically added to the Service Visit, add correction code 18200102 as a
separate activity to the Service Visit.

- Position the thermal sub harness assembly away from the supermanifold.
- Remove and discard the check valve cabin condenser snap ring from the supermanifold.
-
Remove the check valve cabin condenser
from the supermanifold.
CAUTIONIf the check valve separates from the aluminum cap during removal, DO NOT use metal tools. Metal tools may scrape the supermanifold housing causing internal damage. Use fingers or wrap electrical tape around a 90 degree pick instead.
Install
- Use the appropriate oil to lubricate the O-rings on the check valve cabin condenser. Fluids and Capacities for A/C oil specifications. Then install the check valve cabin condenser into the supermanifold.
-
Install a new check valve cabin
condenser snap ring into the supermanifold.
NoteVerify the snap ring is properly seated inside the groove on the supermanifold.
