Samsung RB1944SL/XAA refrigerator Parts

For the Samsung RB1944SL bottom-mount refrigerator, we recommend setting the fresh food (refrigerator) section to 38°F and the freezer to -2°F for normal everyday use. These targets balance food safety, performance, and energy use (see the owner's manual).

Recommended settings and when to adjust

Use these as your starting point, then fine-tune based on how your refrigerator is loaded and your kitchen conditions:

• Normal use: Refrigerator 38°F, freezer -2°F
• Fast freeze (short-term): Set freezer as cold as -14°F for about an hour, then return to normal
• If food is freezing in the refrigerator: Raise the refrigerator setting 1 to 2 degrees
• If ice cream is too soft: Lower the freezer setting a few degrees
• After big changes (restocking, power outage): Give temperatures time to stabilize before adjusting again

How to change the temperature on RB1944SL

The control panel lets you set each compartment within a defined range.

• Press REFRIGERATOR TEMP to cycle settings from 34°F to 46°F
• Press FREEZER TEMP to cycle settings from -14°F to 8°F
• Wait about 5 seconds after selecting; the display returns to showing the average temperature
• If controls will not change, check Child Lock (press the two lock buttons together for 3 seconds to toggle)

Quick reference table

Compartment	Recommended	Adjustable range
Refrigerator	38°F	34°F to 46°F
Freezer	-2°F	-14°F to 8°F

Why it matters

Correct settings help keep perishables out of the temperature “danger zone,” reduce frost and moisture issues, and prevent the compressor from running longer than necessary.

To reset your Samsung RB1944SL bottom-mount refrigerator, unplug it (or turn off the breaker) for about 5 minutes, then restore power and allow 2 to 3 hours for temperatures to stabilize. For control lock issues, use the Child Lock button combo shown in the owner's manual.

Quick reset options (what to try first)

• Power reset (most common): unplug for 5 minutes, then plug back in.
• Control panel lock reset: press the two Child Lock buttons together for 3 seconds to toggle lock on or off.
• Cooling recovery: use Power Cool (fridge) or Power Freeze (freezer) to help the compartments return to the set temperature after a door was left open.
• After any reset: wait 2 to 3 hours before judging cooling performance.

Step-by-step: power reset

1. Move perishable food to a cooler if the doors will be open.
2. Unplug the refrigerator (or switch the circuit breaker off).
3. Wait 5 minutes.
4. Restore power.
5. Set temperatures and close doors; avoid frequent openings for the next few hours.

What the buttons do on this model

Control	What it affects	When to use it
Freezer temperature	Freezer setpoint	Adjust freezer temp if items are soft or too hard
Refrigerator temperature	Fresh food setpoint	Adjust fridge temp if food is warm or freezing
Power Freeze	Freezer boost	After loading groceries or door left open
Power Cool	Refrigerator boost	After door left open or warm food load
Child Lock combo	Locks/unlocks controls	When buttons do not respond

Why it matters

A “reset” clears minor control glitches and restores normal operation, but the refrigerator still needs time to pull temperatures back down. On RB1944SL, a locked control panel can look like a failure even though cooling is normal.

On the Samsung RB1944SL bottom-mount refrigerator, the bottom glass shelf removes by releasing the shelf from its side supports, then lifting the shelf up and pulling it forward out of the fresh food compartment. For the exact shelf handling and cleaning guidance, follow the steps in the owner's manual.

Steps to remove the bottom shelf

• Remove food items from the shelf and clear the area below it.
• Grip the shelf with both hands near the left and right sides.
• Press inward on the shelf release points (one on each side) to disengage it from the supports.
• Lift the front edge slightly to clear the side rails.
• Pull the shelf straight toward you and out of the refrigerator.
• Set the shelf on a towel or flat surface to avoid chipping the glass edge.

Cleaning and reinstalling tips

The manual recommends cleaning shelves with water and detergent, then drying completely. When you put shelves back, keep them in their original positions.

Task	Best practice
Cleaning	Wash with mild detergent and water; dry fully before reinstalling
Reinstalling	Slide shelf in level, then lower into the supports until it seats
Preventing cracks	Avoid twisting the shelf; lift evenly with two hands

Why it matters

Removing the shelf the right way prevents broken glass, avoids damage to shelf supports, and helps maintain proper airflow. Samsung also recommends keeping space between the shelf and the rear wall (about 1/2 inch) for air circulation.

On Samsung refrigerator model RB1944SL, ice at the bottom of the freezer almost always happens when defrost water cannot drain away, so it refreezes under the bottom drawer. Clearing the drain path and reducing warm, moist air leaks at the door usually stops the repeat icing.

Most common causes (and what to check first)

• Defrost drain partially clogged by ice, food debris, or sludge; water backs up and freezes on the freezer floor.
• Drain tube grommet restricted or hardened, slowing water flow to the drain pan.
• Door not sealing tightly (dirty gasket, warped drawer, or items preventing full closure); moist air increases frost.
• Long door-open time; more humidity enters and later freezes (the manual notes shorter open time reduces ice buildup).
• Heavy frost from a defrost problem (sensor or thermal fuse issue) that creates excess meltwater and overflow.

Step-by-step fix you can do safely

1. Unplug the refrigerator before any cleaning.
2. Remove the freezer drawer(s) and melt the ice at the bottom with towels and a bowl of hot water (avoid sharp tools).
3. Locate the defrost drain opening (typically behind the rear panel area); flush with warm water until it flows freely.
4. Clean the door gasket and grooves with mild detergent; the manual recommends cleaning seals and grooves carefully.
5. Reassemble, restore power, and monitor for 24 to 48 hours.

Parts that commonly solve repeat drain icing

Symptom you see	Likely area	Part to consider for RB1944SL
Ice sheet returns in 1 to 3 days	Drain restriction	Refrigerator drain tube grommet da63-00951c
Heavy frost plus warm temps	Defrost circuit	Refrigerator defrost thermal fuse DA47-00095E

Why it matters

When meltwater cannot drain, it refreezes and can block drawers, reduce airflow, and force longer run times. Keeping doors closed tightly and the drain clear helps the automatic defrost system work as intended.

Helpful reference

• Cleaning drawers, door bins, and rubber seals: see the RB1944SL owner's manual.
