Dometic 3311236 Refrigerator Roof Vent: Caps, Bases & Parts Diagram
A Dometic absorption refrigerator with a roof-exhaust installation uses a vent above the refrigerator cabinet to let heated air escape. The 3311236 roof vent family has two main pieces: a lower roof-mounted base and an upper protective cap. If only one piece is damaged, the individual replacement may be all you need. If both are damaged, the matching complete kit contains both parts.

This simplified component guide shows how the parts relate. The manufacturer's dimensioned roof-cutout drawing is included further down the page.
Complete refrigerator roof vent kits
Choose a complete kit when both the rooftop vent cap and the underlying base need replacement. The two kits below are the same manufacturer-listed vent family in different colours. Fasteners are not included in the specified Dometic installation procedure.

Replacement roof vent bases
The base is the lower section secured to the roof around the vent opening. If the mounting flange is cracked or damaged, compare your installed base and roof opening with the replacement rather than ordering only a cap.

Dometic refrigerator roof-vent installation drawing
Dometic's original DM, RM and DMA refrigerator installation manual illustrates roof-vent part family 3311236.xxx and specifies a 23¾ × 6½-inch roof cutout. This is the opening in the roof, not the outside dimension of the cap or base. The drawing appears on page 19 of the manufacturer's manual.

Before replacing a refrigerator roof vent
- Check the part family. Identify the original cap/base design or the manufacturer's installed vent number. A Dometic refrigerator does not automatically use a 3311236 roof vent.
- Determine which piece is damaged. A cap-only replacement cannot repair a cracked base or roof flange. Choose a complete kit if both components require replacement.
- Match the colour and companion part. The white cap 3312695.004 pairs with base 3312694.007; the black cap 3312695.020 pairs with base 3312694.023.
- Check the installation opening and ventilation plan. Dometic's 3311236 installation drawing specifies a 23¾ × 6½-inch roof cutout, along with refrigerator-specific ventilation-height requirements. Do not rely on the roof opening alone to confirm refrigerator compatibility.
- Follow the manufacturer's installation procedure. Dometic specifies separate fasteners for base and cap and sealing over screws. Roof work and propane-refrigerator ventilation should be carried out according to the refrigerator and RV manufacturer's requirements.
These components relate to refrigerator cooling-unit exhaust ventilation, not the RV's plumbing vent or a 14 × 14-inch roof fan opening. See the roof vent lid selection guide when replacing a general-purpose RV roof fan or lid.
