Dometic to Norcold RV Fridge Size & Replacement Guide

Replacing a Dometic or Norcold RV refrigerator starts with the cabinet opening—not the cubic-foot label. This size chart brings together published Dometic enclosure dimensions, Norcold Polar installation ranges and selected new 12V alternatives from NewRVParts, so you can see where a replacement might require framing, ventilation or electrical changes.

Compare enclosure dimensionsUse height × width × depth. These are manufacturer installation openings, not the exterior size of the doors or hinges.
Choose the cooling systemAbsorption refrigerators use AC/LP gas; compressor refrigerators use 12V DC. Connections and installation requirements are different.
Find the exact new modelShop by the complete refrigerator model and door configuration. A similarly sized unit is not automatically a drop-in replacement.

Measure the space that the refrigerator actually fits

  1. Identify the original model: read the full nameplate model, product number and (where applicable) serial number, not just the front-door badge.
  2. Measure the cabinet: height, width and clear depth at multiple points. Note trim and any sloped base.
  3. Measure the travel path: RV entry door, turns, interior doorway and refrigerator face width. A model can fit the cutout but not pass through the RV entry.
  4. Check more than dimensions: hinge side, door swing, rear ventilation, gas and electric connections, 12V wiring and secure anchoring.

Dometic RV refrigerator enclosure size chart

These are the manufacturer's enclosure (rough-in) dimensions for specific DM, RM and DMA absorption refrigerator models, in inches, in height × width × depth order. They are not the outer refrigerator measurements. The model suffix and appliance installation instructions must also be checked.

Dometic models Enclosure H Enclosure W Enclosure D Reference
RM2351 / RM2354 29¾ in 20½ in 21½ in Compact single-door absorption
RM2451 / RM2454 36½ in 23 11/16 in 24 in Compact single-door absorption

RM1350SL 63 3/16 in 32¾ in 24 1/16 in Wide, shallower RM1350SL
Dometic specifies one additional inch of enclosure depth for models marked with optional ventilator-fan requirements in its DM/RM installation table. The cabinet depth and exterior door projection are different measurements; keep the original manufacturer's installation drawing with the model.

Norcold Polar & Furrion 12V opening dimensions

These are model-specific manufacturer installation openings, not outside dimensions. Norcold N7X/N8X are absorption refrigerators; N8DC/N10DC, NV8DC, Dometic DMC4081/DMC4101 and Furrion Arctic models are 12V compressor units. The Polar Value NV8DC has a 21.65-in minimum depth, whereas the older N8DC requires 24 in; Dometic DMC4081/DMC4101 need a wider 24-in opening.

Manufacturer model System Opening H Opening W Opening D
Norcold N7X / N7V / N7LX AC/LP absorption 52.88–53.01 in 23.50–23.63 in 24.00 in
Norcold N8DC 12V compressor 52.88–53.01 in 23.50–23.63 in 24.00 in
Norcold NV8DC 12V compressor 52.88–53.01 in 23.50–23.63 in 21.65 in minimum
Furrion FCR08DCGTA-BL/BR 12V compressor 52¾–53 in 23⅜–24 in 24 minimum in
Norcold N8X / N8V / N8LX AC/LP absorption 59.88–60.01 in 23.50–23.63 in 24.00 in
Norcold N10DC 12V compressor 59.88–60.01 in 23.50–23.63 in 24.00 in
Furrion FCR10DCGTA-BL/BR 12V compressor 59¾–60 in 23⅜–24 in 24 minimum in
Norcold N15DC 12V compressor 63.25–63.38 in 32.69–32.82 in 24.00 in
Dometic DMC4081 12V compressor 53.9 in 24 in 24 in
Dometic DMC4101 12V compressor 59.9 in 24 in 24 in

Keep these width and depth tolerances separate. For the NV8DC, Norcold specifies framing or shimming to 23.50–23.63 in at the breaker mounting points and correct placement in deeper cavities. Dometic DMC4081/DMC4101 need a 24-in-wide opening. Compare each manual before altering the cabinet.

Dometic model-to-replacement opening size chart

Find your existing Dometic model in the left column, then compare the replacement refrigerator's required opening alongside it. A matching number of inches is only a dimensional starting point, not an approved drop-in replacement: door swing, power, support, ventilation and mounting must all meet the new manufacturer's instructions.

Original Dometic model Original enclosure (H × W × D) New refrigerator opening to compare Dimensional fit assessment
RM2351 / RM2354 29¾ × 20½ × 21½ in Dometic RM2351 or Dometic RM2354 — 29¾ × 20½ × 21½ in Same nominal Dometic opening. Two-way versus three-way power, door swing and approved gas ventilation still require verification. No Norcold direct-size match is established here.
RM2451 / RM2454 36½ × 23 11/16 × 24 in RM2451 / RM2454 family — 36½ × 23 11/16 × 24 in Same-sized Dometic family is the reference. No verified current Norcold/12V cutout match is listed for this compact opening; see the compact replacement guide.
RM2551 / RM2554 42⅝ × 23 11/16 × 24 in RM2551 / RM2554 family — 42⅝ × 23 11/16 × 24 in Same-sized Dometic family is the reference. No verified current Norcold/12V direct-fit opening has been established for this group.
DM2652 / DM2662 / DM2663 53¾ × 23 11/16 × 24 in Same-opening Dometic: Dometic DM2672 — 53¾ × 23 11/16 × 24 in
Norcold: Norcold N7X (AC/LP) or Norcold N8DC (12V) — 52.88–53.01 × 23.50–23.63 × 24 in
Furrion: Furrion FCR08DCGTA (12V) — 52¾–53 × 23⅜–24 × 24 in 		Dometic shares the nominal opening. Norcold and Furrion have different height or width tolerances; support, fitting trim and electrical/venting changes must be reviewed.
DM2672 / DM2682 / DM2683 53¾ × 23 11/16 × 24 in Same-opening Dometic: Dometic DM2672 — 53¾ × 23 11/16 × 24 in
Norcold: Norcold N7X (AC/LP) or Norcold N8DC (12V) — 52.88–53.01 × 23.50–23.63 × 24 in
Furrion: Furrion FCR08DCGTA (12V) — 52¾–53 × 23⅜–24 × 24 in 		Dometic shares the original opening. The shorter Norcold/Furrion candidates are not approved drop-in replacements without the required framing and systems review.
DMA4061 / DMA4064 / DMA4067 / DMA4068 53¾ × 23 11/16 × 22¼ in Same-depth DMA406 family: 53¾ × 23 11/16 × 22¼ in
Norcold N8DC / Furrion FCR08DCGTA: required depth approximately 24 in 		The 12V candidates require about 1¾ in more cabinet depth than the listed DMA enclosure. Do not treat these as fitting without modification and full installation clearance.
RM3762 53¾ × 23 11/16 × 24 in Same-opening Dometic: Dometic DM2672 — 53¾ × 23 11/16 × 24 in
Norcold: Norcold N7X (AC/LP) or Norcold N8DC (12V) — 52.88–53.01 × 23.50–23.63 × 24 in
Furrion: Furrion FCR08DCGTA (12V) — 52¾–53 × 23⅜–24 × 24 in 		Similar Dometic opening; Norcold/Furrion options are shorter. Confirm LP-gas ventilation when retaining absorption cooling or rework power and venting for 12V.
DM2852 / DM2862 59 15/16 × 23 11/16 × 24 in Same-opening Dometic: Dometic DM2872 — 59 15/16 × 23 11/16 × 24 in
Norcold: Norcold N8X (AC/LP) or Norcold N10DC (12V) — 59.88–60.01 × 23.50–23.63 × 24 in
Furrion: Furrion FCR10DCGTA (12V) — 59¾–60 × 23⅜–24 × 24 in 		The Dometic option has the same nominal opening. The Norcold/Furrion size ranges overlap, but width tolerances, door projection and mounting require checking.
DM2872 / DM2882 59 15/16 × 23 11/16 × 24 in Same-opening Dometic: Dometic DM2872 — 59 15/16 × 23 11/16 × 24 in
Norcold: Norcold N8X (AC/LP) or Norcold N10DC (12V) — 59.88–60.01 × 23.50–23.63 × 24 in
Furrion: Furrion FCR10DCGTA (12V) — 59¾–60 × 23⅜–24 × 24 in 		The Dometic option shares the original nominal opening; the other models are size candidates, not confirmed no-modification replacements.
DMA4081 / DMA4084 / DMA4087 59 15/16 × 23 11/16 × 22¼ in Same-depth DMA408 family: 59 15/16 × 23 11/16 × 22¼ in
Norcold N10DC / Furrion FCR10DCGTA: required depth approximately 24 in 		These 12V candidates require roughly 1¾ in additional depth. Confirm that cabinet construction and surrounding clearances permit a compliant alteration.
RM3962 62 15/16 × 23 11/16 × 24 in Norcold N10DC (12V) — 59.88–60.01 × 23.50–23.63 × 24 in
Dometic DM2872 (AC/LP) — 59 15/16 × 23 11/16 × 24 in 		These alternatives are about 3 in shorter than the old opening. A sound support base and finished upper infill are required; check the complete installation and power supply.
RM1350 63 3/16 × 32¾ × 26 1/16 in Norcold N15DC (12V compressor) — 63.25–63.38 × 32.69–32.82 × 24 in Original opening is 1/16 in shorter than N15DC minimum. Height must be increased and the deeper recess handled per Norcold's depth and rear-baffle instructions.
RM1350SL 63 3/16 × 32¾ × 24 1/16 in Norcold N15DC (12V compressor) — 63.25–63.38 × 32.69–32.82 × 24 in Original opening is 1/16 in shorter than N15DC minimum. Verify a safe height alteration, required framing, door clearance and conversion to 12V.

Keep the refrigerator type and power supply in mind

If you are retaining propane/electric absorption cooling, the rear LP-gas ventilation and flue arrangement must follow the selected manufacturer's instructions. A 12V compressor conversion needs an adequate DC electrical supply, wire sizing, fusing and cabinet ventilation appropriate to that appliance; decommissioning the old LP gas connection must be handled properly.

Door swing, ventilation trim, shelf clearance and whether a model requires separately purchased door panels matter just as much as the nominal enclosure size. For example, Furrion's black-framed Arctic models may require decorative door panels purchased separately.
