Samsung RF22R7351SG/AA-00 refrigerator Parts

For your Samsung RF22R7351SG refrigerator, the right water filter is the one specified for this exact model and the filter housing it uses. We recommend matching the replacement to the filter cartridge style shown in the RF22R7351SG owner's manual and using only Samsung-provided or Samsung-approved filters to prevent leaks and dispenser problems.

• Check the model number on the rating label inside the fresh food compartment; it must match RF22R7351SG.
• Remove the current filter and match the cartridge style (how it locks in and the knob/handle style).
• Use the manual’s “Water filter” section to confirm the correct replacement type for this model.
• If you use reverse osmosis (RO), confirm your water pressure meets the refrigerator’s requirements before blaming the filter.
• Avoid third-party filters; unapproved filters can leak and cause water flow issues.

Samsung’s guidance for this refrigerator is to use Samsung-provided or Samsung-approved water filters. Using an unapproved filter can lead to leaking, reduced water flow, and dispenser performance problems.

A correct, approved filter protects water quality and helps prevent leaks that can damage components like the water inlet valve and ice maker system.

No. Samsung refrigerator water filters are not universal; the correct filter depends on your specific refrigerator model and the filter housing it uses. For Samsung model RF22R7351SG, match the replacement to the filter type listed in the RF22R7351SG owner's manual or printed on your current filter.

Use one of these reliable checks before you buy:

• Read the filter model printed on the existing cartridge (remove it and look at the label)
• Check the filter section in the RF22R7351SG owner's manual
• Confirm the filter shape and locking style (twist-lock quarter turn is common)
• Verify your water supply setup; low pressure can mimic a “bad filter” symptom
• Avoid off-brand filters; unapproved filters can leak and cause damage

Samsung uses multiple filter families across different refrigerator lines. Even if two filters look similar, the seal design and bypass valve can differ, so the wrong one may not fit, may leak, or may restrict water flow.

A mismatched filter can cause slow dispensing, weak ice production, or water leaks. Samsung also warns against using unapproved third-party filters because they can leak and damage the refrigerator.

After installing the correct filter:

• Shut off the water supply before removal
• Turn the cartridge counterclockwise about a quarter turn to unlock (common Samsung design)
• Turn the water back on and flush several cups of water to clear air and carbon fines
• Reset the filter indicator on the control panel (per the manual)

Cooling problems are the most common issue we see on Samsung refrigerators, including the Samsung RF22R7351SG; symptoms include a warm fresh-food section, temperature swings, or poor airflow caused by frost buildup, blocked vents, or a fan/defrost-related failure. Start with the basic checks and then use the troubleshooting steps in the RF22R7351SG owner’s manual.

• Fresh-food section is warm but the freezer seems OK
• Frost or ice buildup that restricts airflow
• Refrigerator runs a lot or seems louder than normal
• Ice maker stops producing ice or makes small/hollow cubes
• Water dispenser flow is weak or intermittent

• Confirm the power cord is fully plugged in and the outlet works.
• Set the temperature colder and allow 24 hours to stabilize.
• Make sure interior air vents are not blocked by food packages (blocked vents can cause overcooling or poor circulation).
• Verify the refrigerator has adequate clearance from walls and cabinets for airflow.
• If the unit was unplugged, wait at least 5 minutes before plugging it back in.

Cooling and airflow problems can look like a “sealed system” failure when the real cause is simpler, such as blocked vents, incorrect settings, or a failed sensor. Catching it early helps protect food and reduces strain on the compressor.

If your main complaint is ice production, we recommend following the steps in why your Samsung fridge stopped making ice and how to fix it to rule out common causes before replacing parts.

Yes. For the Samsung RF22R7351SG, the built-in filter reminder is designed around about 6 months of use (typically about 300 gallons), because filter media loads up over time and can reduce flow and water quality even if the water still looks clear. See the replacement and reset details in the RF22R7351SG owner's manual.

Replace the filter earlier than 6 months if you notice any of these common signs:

• Water tastes or smells off
• Water flow at the dispenser slows down
• Ice cubes get smaller or hollow
• The filter indicator starts blinking/red (your reminder is based on time and usage)
• You have hard water or high lime scale (filter life is shorter)

A new filter needs flushing, and the indicator needs a reset.

• Shut off the water supply before removing the cartridge
• Install the new cartridge and restore water supply
• Flush about 1 gallon of water through the dispenser (roughly 6 minutes)
• Discard the first 1 to 2 days of ice (or the first 1 to 2 buckets) to clear the line
• Press and hold Filter Reset for 3 seconds to clear the filter light

A saturated filter can restrict water to the dispenser and ice maker, and it can let taste and odor issues creep back in. Replacing on schedule also helps you troubleshoot correctly; if flow is weak after a fresh filter, we focus next on water pressure, the supply line, or the refrigerator water inlet valve DA62-04027A.

The most commonly replaced refrigerator parts are the ones that handle water flow, airflow, temperature sensing, and door sealing. On a Samsung RF22R7351SG, that typically means items like the water inlet valve, ice maker components, fan motors, temperature sensors, and the electronic control board; shelves and bins also get replaced from everyday wear.

• Water filter (and related filter housing components)
• Door gasket (door seal) and door alignment hardware
• Ice maker parts (ice maker assembly, ice room fan)
• Water inlet valve (feeds the dispenser and ice maker)
• Temperature sensors (thermistors) that report cabinet temperature
• Fan motors (condenser fan and evaporator-area fans)
• Electronic control board (when cooling or dispensing functions act erratically)

These are model-matched examples we often see replaced when symptoms point to them:

• Water and ice parts: mineral buildup, restricted filters, low water pressure, or frozen lines
• Fans and sensors: normal wear, frost buildup, or airflow blockage from overpacked shelves
• Door seals and hinges: frequent opening, misalignment, or debris on the gasket sealing surface
• Control boards: power surges or moisture exposure over time

We recommend these quick checks first because they often point to the right system:

• Confirm the unit is on its own dedicated outlet and the plug is seated firmly.
• Unplug power before servicing or replacing any part.
• Check for obvious airflow blockage (packed vents, heavy frost, blocked return vents).
• For water issues, verify the shutoff valve is fully open and the supply line is not kinked.
• For ice issues, inspect the ice bucket for clumps and confirm the ice maker is turned on.

Replacing the correct “system” part (water supply, ice maker, airflow, sensing, or controls) prevents repeat failures and protects food temperatures. For model-specific component locations and safety steps, follow the RF22R7351SG owner's manual.
