Samsung RF18 Counter-Depth French Door Fridge

The RF18 is a compact, counter-depth French-door refrigerator, so its recurring faults cluster around the ice and cooling systems rather than the cabinet. Below are the covered models, the common problems, the codes, the wear parts, and a repair-or-replace line.

Models covered#

Three variants built from 2021 to 2024 share one platform:

Error codes#

• Error 5E — tap through for the full diagnosis

For an unlisted code, unplug or trip the breaker for 60 seconds and restore power; a returning code needs a diagnosis.

Recall status#

There are no active recalls on the Samsung RF18 series as of 2026-05-28. Check your model against the Consumer Product Safety Commission list at cpsc.gov from time to time.

Repair or replace?#

Refrigerators earn a longer age window than most appliances. For the RF18: under 12 years old with a fix below 50% of a comparable new unit, repair. After 12 years, weigh recent costs — once repairs over the last 2-3 years exceed 40% of replacement, replace. Ice-maker and defrost repairs are inexpensive, but a compressor failure past 12 years usually favors replacement.

Maintenance#

Give the ice maker at least 20 psi of supply pressure — a weak line is the top cause of the number-one complaint. Replace the HAF-QIN water filter every 6 months and clean the condenser coils once a year. Hold the fresh-food compartment near 37 degrees F and the freezer at 0 degrees F, and if frost builds up, run a forced defrost by holding Energy Saver and Fridge together for 8 seconds.

FAQ#

Why is my Samsung RF18 ice maker not making ice?#

The RF18 has a smaller ice maker than full-size models and is sensitive to supply pressure, so confirm at least 20 psi and check for a clogged water filter first. If both are fine, the water inlet valve (DA62-04027A) is the next suspect.

How much space does an RF18 counter-depth need?#

It is built to sit flush with standard 24-inch-deep cabinets, needing about 1 inch of clearance on each side and 1 inch at the rear for airflow. Choking that airflow makes the compressor overwork and short-cycle.

The freezer keeps frosting over — what causes that?#

Frost buildup usually points to the defrost heater (DA47-00244U) or a defrost cycle that is not completing. Running a forced defrost clears the ice, but repeated frosting means the heater needs attention.
