CAPILLARY TUBE REPLACEMENT INSTRUCTIONS
Refrigerators and Freezers
Depending on what model; cabinet you may have you will always have a couple of options when it comes
to replacing the capillary tube.
Some model cabinets for example GDM slide door cabinets have capillary tube/suction line assembly behind
the rear center shelf standard. These are easy to access and change. On refrigerator cabinets that do not have
a rear center shelf standard, here are you options.
1. You can run a new suction line/capillary tube assembly up the rear of the cabinet and drill a hole above
the evaporator housing to bring the tubing inside the cabinet to pipe back to the evaporator.
2. Cut the suction line a couple of inches below where it enters the cabinet also cut it a couple of inches
from the evaporator coil. Install new capillary tube inside of the existing suction line. Now use Tee's to
reconnect suction line while feeding capillary tube out of the other side of the Tee.
The above methods of replacing capillary tubes on refrigerators can also be used on freezers. There is also
one other option that is used only on freezers.
1. Drill a hole in the rear left hand corner through the floor on the inside of the cabinet, run the new
assembly up the rear left hand corner and reconnect to the evaporator. After re-piping cover the
assembly up with a corner cover that can be ordered from True's parts department.
Remember that P.O.E. oil is now being used and it is very hygroscopic. You should only have the system
open for no more than 15 minutes and then replace drier and pull a 200-micron vacuum through both sides
of the system.
