12. Refrigerator ﬁ ns are attached in different ways, varying by make and model.

a. Norcold refrigerator ﬁ ns will remain in place in the box during the entire removal and installation process.

(The screws will be removed.)

b. Double-door Dometic ﬁ ns will be extracted with the cooling unit (with the exception of the RM 100).

c. Single-door Dometic ﬁ ns will be removed from inside the refrigerator.

d. If you are unsure of the procedure for your unit, remove all ﬁ n screws and determine if the refrigerator ﬁ ns are behind or

in front of the plastic liner. Fins that are in front of the liner can be removed before the unit is taken out.

13. Lay the refrigerator face down on the ﬂ oor, using a blanket or some other protection under the front edge and hinges.

a. Remove all plastic trim to avoid damage to the bottom trim, door locks, etc.

14. Dometic double-door refrigerators have exposed freezer tubes that can be used to help extract the cooling unit. Please place a

piece of 6x6 wood, 10 to 11 inches long, on the ﬂ oor. Lay the refrigerator face down so the freezer tubes rest on the wood before

the refrigerator touches the ﬂ oor. This will help push the cooling unit out after the screws are removed.

15. Remove all cooling unit mounting screws from the back of the refrigerator.

16. Label and disconnect the heating element wires from the terminal junctions.

17. Remove the burner cover and mounting screws.

a. Some Dometic refrigerators have a lever lock burner mount. Remove it now.

b. Some models require the complete removal of the burner line and thermocoupler so the cooling unit will clear.

c. Some models require the complete removal of the circuit board and burner so the cooling unit will clear.

d. Check for a ground wire on the bottom of the cooling unit and remove it.

18. Make sure all cooling unit mounting screws have been removed.

a. Dometic models RM 760, 761, 763, 1300, 1301, 1303, 2800, 2801 and 2803 will usually have hidden screws near the large

tube coming from the foam block. Look closely; you will have to remove some of the foil and foam backing to see them.

19. Pry and pull on the large tube near the middle of the cooling unit only.

a. Avoid prying on any brackets, as they may break away from the cooling unit, causing a spray of ammonia.

b. When using a pry bar, protect the refrigerator box with a block of wood under the pry bar to help prevent punctures.

c. If you’re using a block of wood in the freezer of Dometic models (see step #14 above), push hard and steady on the top

corners of the refrigerator toward the ﬂ oor. When the seal is broken the cooling unit can be removed.

d. All cooling units need a steady lift on the large tube coming out of the foam block to be removed.

20. If the ﬁ ns are still attached, carefully remove them without bending them.

a. If necessary you can chip away some of the foam block of the unit to assist in removal of the ﬁ ns. Do not damage the

foam of the refrigerator box.

21. Remove the sheet metal, insulation, heating element and ﬂ ue tube bafﬂ e from the old cooling unit.

a. Install these items onto your new ATCO America cooling unit.

1. If the insulation is wet it has to be dried or replaced with high-temperature insulation before installing the sheet

metal on the cooling unit.

2. If the insulation is wet, check your RV refrigerator roof vent and repair or replace it if it’s damaged or missing,

to prevent future leaks. Insulation must be dry for the unit to function properly.
