Frigidaire LGHK2336TF4 side-by-side refrigerator Parts

Yes. A side-by-side refrigerator like the Frigidaire LGHK2336TF4 has a freezer compartment; the cabinet is split into two full-height sections with the refrigerator on one side and the freezer on the other. For feature and control details, use the LGHK2336TF4 owner’s manual.

How the compartments are typically laid out

Most side-by-side designs use this left-right split so you can access both fresh food and frozen food from standing height.

• One vertical compartment is refrigerator (fresh food)
• The other vertical compartment is freezer
• Both doors open independently
• Many models include in-door ice and water dispensing (if equipped and connected)
• Door bins, shelves, and drawers are arranged to match each side’s temperature zone

Quick comparison: side-by-side vs other common styles

Refrigerator style	Freezer location	What it’s best for
Side-by-side	Full-height compartment on one side	Easy access to both sections; narrow door swing
Top-freezer	Freezer on top	Simple layout; often more usable freezer width
Bottom-freezer	Freezer on bottom	Fresh food at eye level; larger refrigerator shelves

Why it matters

Knowing that your LGHK2336TF4 has a dedicated freezer section helps when you are troubleshooting temperature issues, organizing airflow, or planning installation clearances so both doors can fully open. The installation guidance and door-opening requirements are covered in the LGHK2336TF4 installation guide.

On the Frigidaire LGHK2336TF4 side-by-side refrigerator, “H” or “HI” on the temperature display means the High Temp alarm. It indicates the refrigerator or freezer temperature has been too warm for a period of time, commonly after a door is left open or right after first power-up.

What to do right away

• Make sure both doors are fully closed and not blocked by bins or food packages.
• Check the door gaskets for gaps, tears, or areas not sealing.
• Press MUTE ALARM to silence the alarm after you correct the cause.
• If the unit was just plugged in, allow time for temperatures to stabilize.
• Confirm the temperature settings are at normal targets (typically 37°F fresh food and 0°F freezer).

Normal situations vs. a real cooling problem

When you see “H/HI”	What it usually means	What we recommend
Right after power is turned on	The display can show “HI” during the initial startup period	Wait for the unit to pull down to temperature; avoid frequent door openings
After a door was left open	Warm air entered the cabinet	Close the door, check gasket seal, press MUTE ALARM
Ongoing, even with doors closed	Cooling performance issue	Check airflow, condenser area, and consider diagnosis steps below

If “H/HI” keeps coming back

1. Airflow: Do not block vents inside the refrigerator or freezer.
2. Room temperature: Very hot or very cold rooms can affect cooling performance.
3. Condenser area: Clean dust from the condenser area so heat can dissipate.
4. Fan operation: If you suspect weak airflow in the freezer, review how to fix your evaporator cooling fan.
5. Error indicators: If the display flashes codes or behaves unusually, use Frigidaire refrigerator error codes to identify what the control is reporting.

Why it matters

High temperatures can lead to food safety issues and can also point to a door-seal problem, airflow restriction, or a developing cooling-system fault. Catching the cause early helps your LGHK2336TF4 recover faster and run more efficiently.

For model-specific control behavior and alarm details, follow the temperature and alarm sections in the LGHK2336TF4 owner’s manual.

On the Frigidaire LGHK2336TF4 side-by-side refrigerator, we use the control panel to check for alarms, reset settings, and confirm key functions (cooling, ice maker, filters). This model’s LGHK2336TF4 owner’s manual focuses on control and alarm behavior rather than a step-by-step “diagnostic mode,” so we recommend using the built-in indicators and alarm checks as your primary on-board tests.

Quick on-board checks you can run

• Check the temperature display behavior after power-up; it can show “HI” for a period before showing actual temps.
• Mute and clear alarms using the alarm reset function when a door-ajar or other alarm is active.
• Toggle the ice maker using the ICE MAKER ON-OFF key (press and hold 3 seconds).
• Reset to factory defaults using DEFAULT SETTINGS (press and hold 3 seconds).
• Check filter status screens for AIR FILTER and WATER FILTER; reset the status after replacement.

Control panel “test” actions (what they do)

These are the most useful built-in checks because they confirm the user interface is responding and the feature is enabled.

Control/indicator	How to use it	What it tells you
ICE MAKER ON-OFF	Press and hold 3 seconds	Confirms ice maker enable/disable command works
DEFAULT SETTINGS	Press and hold 3 seconds	Confirms control can reset configuration
AIR FILTER	Press to view status; hold 3 seconds to reset	Confirms filter monitor and reset function
WATER FILTER	Press to view status; reset after replacement	Confirms filter monitor and reset function

If the display is flashing or acting abnormal

A flashing digital temperature display indicates the electronic control has detected a performance problem. Use this approach:

• Write down any letters/numbers shown on the display.
• Power-cycle the refrigerator (turn cooling OFF, wait 3 to 5 minutes, then turn it back ON).
• If the flashing returns, service is typically needed to interpret the code.

For code lookups and what they mean, use our Frigidaire refrigerator error codes resource.

Why it matters

Running these checks helps you separate a simple settings issue (ice maker turned off, alarm condition, filter status) from a true cooling or control problem that needs deeper troubleshooting.

On most Frigidaire side-by-side refrigerators, the defrost function is controlled by the main electronic control rather than a separate, serviceable defrost timer. For the Frigidaire LGHK2336TF4, use the wiring and component location details in the LGHK2336TF4 owner's manual to identify the defrost control components for your exact configuration.

What you will typically find on LGHK2336TF4

Many newer Frigidaire side-by-side models use an adaptive defrost system (control board logic plus sensors) instead of a mechanical timer. That means you usually will not find a small dial-style timer behind the toe grille or inside the control housing.

Common defrost-related components to look for:

• Electronic control board (often in the control housing or rear service area)
• Defrost heater (on/under the evaporator coil in the freezer)
• Defrost thermostat or temperature sensor (thermistor)
• Evaporator fan and airflow path (ice buildup here can mimic a defrost failure)

Quick checks before you go looking for a “timer”

These steps help confirm whether you are dealing with a defrost issue versus an airflow or control setting problem:

• Check for heavy frost on the freezer back wall (classic defrost symptom)
• Confirm doors are sealing and closing fully (warm air causes frost)
• Verify temperature settings are reasonable (freezer near 0°F, fresh food near 37°F)
• Listen for the evaporator fan running (no airflow can cause warm temps)
• Power-cycle the refrigerator for 5 minutes to reset controls (temporary logic lockups)

Parts that commonly relate to defrost symptoms

If you have frost buildup and warming temperatures, these model-matched parts are often involved:

Symptom	Common cause	Example model-matched part
Frost blanket on freezer back wall	Air not moving across coil	Refrigerator evaporator fan blade 5308000010
Temps swing or alarms	Sensor reading off	Refrigerator temperature sensor 240597220
Multiple functions act erratically	Control not managing defrost correctly	Frigidaire refrigerator electronic control board 5304512770

Why it matters

A true defrost failure can block airflow through the evaporator, which warms the fresh food section first and can lead to poor ice production. Finding the correct control method (timer vs. electronic defrost) prevents unnecessary part swaps and speeds up the repair.

On the Frigidaire LGHK2336TF4 side-by-side refrigerator, most “error” messages clear by resetting the active alarm or restoring default settings from the control panel. Start by pressing the correct alarm reset key; if the code returns, use the factory default reset and then troubleshoot the underlying cause.

Quick reset steps (in-door controls)

• Door ajar alarm: press SET (some control versions use MUTE ALARM) to reset the alarm.
• Flapper (ice chute) alarm: remove the jammed ice holding the chute open; then press SET to reset.
• High temp detected: press MUTE ALARM to silence the alarm; the indicator stays on until temperatures drop below the alarm threshold.
• Factory default reset: choose DEFAULT SETTINGS, then press and hold SET for 3 seconds to restore factory settings.
• Power cycle reset (soft reset): unplug the refrigerator (or switch the breaker off) for 5 to 15 minutes, then restore power.

For the exact button names and layout used on your dispenser, follow the control descriptions in the LGHK2336TF4 owner’s manual.

What to do if the code comes back

A repeating code or alarm usually means the refrigerator is still detecting a condition that needs attention.

• Confirm both doors fully close and the gaskets seal
• Clear any ice jam in the dispenser chute
• Verify freezer and fresh food temperature settings are reasonable
• Replace and reset filter indicators when due (water filter and air filter each reset by holding SET for 3 seconds in their menu)
• If cooling performance is off, check airflow and listen for fan operation

Common “cause and next step” guide

What you see	What it usually means	What to do next
Door ajar indicator/alarm	Door left open 5+ minutes	Close door, press SET or MUTE ALARM
Flapper alarm	Ice chute door held open by ice	Remove jam, press SET
High temp detected	Compartment warmed above threshold	Press MUTE ALARM, verify temps and door sealing
Filter status “Order/Replace”	Filter life timer reached	Replace filter, then reset status

Why it matters

Resetting clears the alarm display, but it does not fix the condition that triggered it. Addressing the root cause prevents food temperature swings, nuisance alarms, and dispenser or ice maker interruptions.

On Frigidaire model LGHK2336TF4, the SY EF code points to an evaporator fan or airflow problem. We fix it by power-cycling the refrigerator, checking for ice buildup or obstructions around the fan, and inspecting fan wiring; if the fan circuit tests bad, replace the failed part.

Quick fixes to try first

• Unplug the refrigerator for 5 to 10 minutes, then plug it back in.
• Make sure freezer vents are not blocked by food packages.
• Remove the ice bin and check for ice jams that can restrict airflow.
• If you see heavy frost on the freezer back wall, defrost the unit (doors open, towels down) until airflow returns.
• Confirm the freezer temperature is set in a normal range (many owners use 0°F as a target; your control range is -6°F to +4°F).

What to check if the code comes back

Evaporator fan area

SY EF commonly shows up when the evaporator fan cannot move air.

• Listen for the fan running when the freezer door switch is held in.
• Look for ice contacting the fan blade.
• Inspect the fan blade for cracks or rubbing.

If the blade is damaged or packed with ice, the correct replacement for this model is the refrigerator evaporator fan blade 5308000010.

Wiring and controls

Use the LGHK2336TF4 owner’s manual to locate the fan, door switch, and control panel functions.

• Check harness connections at the fan motor and control.
• Look for pinched wires or corrosion at connectors.
• Reset to factory defaults if your control offers a default reset option.

Symptoms and likely causes

What you notice	Most likely cause	What usually fixes it
Freezer warming, fridge warming	Evaporator fan not moving air	Clear ice, repair wiring, replace fan parts
Loud buzzing or scraping	Ice hitting fan blade	Defrost and clear obstruction
Code returns after reset	Fan circuit or control issue	Diagnose fan motor, wiring, or control

Why it matters

The evaporator fan circulates cold air from the freezer to both compartments. When airflow drops, temperatures rise, frost can build faster, and the refrigerator may run longer and louder.
