Frigidaire FRS23H5ASB8 refrigerator Parts

On a Frigidaire FRS23H5ASB8 side-by-side refrigerator, an H or HI code means a high temperature alarm. It indicates the refrigerator or freezer temperature has been too warm for an extended period, most often from a door left ajar or a door seal that is not closing tightly.

What to do right away

• Make sure both doors fully close and nothing inside is blocking them.
• Check the door gaskets for gaps, tears, or sticky spots; clean and dry the sealing surfaces.
• Confirm the temperature controls were not accidentally set warmer.
• Give the refrigerator 24 hours to stabilize after any control change or after loading a lot of warm food.
• If the alarm returns, listen for normal airflow sounds (fans running) and check for heavy frost buildup that can restrict cooling.

Common causes and quick checks

Likely cause	What you will notice	Quick check
Door left open or not sealing	Warm temps, alarm after an hour or more	Inspect gasket contact all the way around
Frequent door openings	Temps rise during busy use	Reduce openings for a few hours
Warm food load	Alarm after grocery load	Allow 24 hours for recovery
Airflow restriction (frost/blocked vents)	Uneven temps, weak airflow	Clear vents; check for excessive frost

Why it matters

High temperatures can lead to food spoilage and can also cause the ice maker to slow down or stop until the freezer temperature recovers. A good door seal and steady airflow help the compressor and fans maintain safe temperatures.

Helpful references for this model

• Use the FRS23H5ASB8 owner's manual for alarm behavior, temperature control guidance, and operating tips.

Food freezes in the fresh food section of your Frigidaire FRS23H5ASB8 when the refrigerator temperature is set too cold or when airflow from the freezer is blowing directly onto items. We fix this by adjusting the fresh food control gradually and keeping the air vents clear (per the owner's manual).

Quick checks that solve most “freezing in the fridge” complaints

• Set the fresh food control slightly toward Cold (warmer), then wait 24 hours before adjusting again.
• Make sure packages are not blocking the cold air vents; blocked vents cause uneven temperatures.
• Avoid overpacking shelves; overcrowding reduces air circulation and creates cold spots.
• Keep liquids and produce away from the back wall and vent areas where air is coldest.
• Confirm doors close tightly so the control system can regulate temperatures normally.

Recommended temperature targets

The manual’s food storage guidance for this style of refrigerator is:

Compartment	Target temperature	What happens if too cold
Fresh food (refrigerator)	34°F to 40°F (optimum 37°F)	Produce and drinks freeze, items near vents freeze first
Freezer	0°F or lower	Ice cream gets rock hard, frost can increase

When it points to a part or airflow control issue

If the controls are set correctly and food still freezes, the most common causes are airflow problems between compartments.

Symptoms and likely causes

• Freezing is worst on the top shelf or near the vent: damper stuck too open or airflow path blocked.
• Freezing happens after loading groceries: items placed in front of vents create a cold blast zone.
• Temperatures swing a lot: control or sensor issues (less common than airflow/packing).

A damper that is stuck open can overfeed freezer air into the refrigerator side; for this model, the related part is the refrigerator damper 241600902.

Why it matters

Freezing in the fresh food compartment is usually an airflow and temperature control problem, not a “more cooling is better” situation. Correct settings and clear vents protect food quality and help the refrigerator run efficiently.

On the Frigidaire FRS23H5ASB8, defrost operation is handled by an automatic defrost control system, not a stand-alone “timer” you adjust regularly. The defrost control is typically accessed from the temperature control area in the fresh food section or the control box area; use the FRS23H5ASB8 owner's manual for the exact access points and panel removal steps.

What you are actually looking for on FRS23H5ASB8

Most side-by-side Frigidaire designs in this series use an automatic defrost control with defrost components in the freezer section.

• Defrost control: located in the control housing/control box area (not in the freezer behind the evaporator cover)
• Defrost heater and wiring: located at the evaporator area behind the freezer rear panel
• Defrost thermostat: clipped to the evaporator tubing; it opens and closes based on temperature

If you are diagnosing a defrost problem, the refrigerator defrost bi-metal thermostat 5303918214 is one of the key parts in the defrost circuit.

Quick access checklist (safe approach)

Before removing any covers:

• Unplug the refrigerator to prevent shock
• Move food away from the control housing area to avoid damage
• Remove the control housing cover screws (commonly Phillips-head)
• Support the housing as you lower it; do not pull on wires
• Label or photograph wire connections before disconnecting anything

“Defrost timer” vs. defrost control: how to tell

What you find	What it is	What it means for location
Dial/advance slot you can turn with a screwdriver	Mechanical defrost timer	Usually mounted in a control housing or behind a small access cover
Small electronic module/board with wiring harness	Automatic defrost control	Usually in the control box/control housing area

Why it matters

Knowing whether you have a mechanical timer or an automatic defrost control prevents unnecessary disassembly and helps you test the right components first (defrost thermostat, heater circuit, airflow). For cooling complaints, also inspect evaporator airflow and frost buildup patterns.
