Whirlpool WRX735SDHB00 bottom-mount refrigerator Parts

On Whirlpool refrigerators like model WRX735SDHB00, the most common service issue we see is cooling trouble caused by frost buildup (a defrost problem), which can make the fresh food section warm while the freezer seems closer to normal. Use the WRX735SDHB00 owner's manual to confirm the exact defrost and temperature checks for your unit.

What you’ll usually notice

• Refrigerator section warming up or fluctuating temperatures
• Frost or ice buildup on the freezer back wall
• Fan noise changes (fan hitting ice) or reduced airflow from vents
• Longer run times, or the compressor seems to run often
• Ice maker output drops because airflow and temps are off

Quick checks we recommend first

1. Check the door seal: A leaking gasket lets humid air in and accelerates frost.
2. Verify airflow: Make sure vents are not blocked by food packages.
3. Set temps correctly: Give changes 24 hours to stabilize.
4. Look for heavy frost: If the freezer back panel is iced over, defrost system troubleshooting is next.
5. Rule out sensor issues: A bad temperature sensor can cause erratic cooling.

Parts that commonly relate to these symptoms

If your symptoms match, these model-specific parts are often involved:

Symptom	Common area to check	Example part for WRX735SDHB00
Frost buildup, warm fridge	Defrost control and sensing	Refrigerator thermistor W10316760
Warm temps, inconsistent operation	Main control logic	Refrigerator electronic control W11043763
Poor ice production with cooling issues	Ice maker system (secondary symptom)	Refrigerator ice maker assembly WPW10300024

Why it matters

Defrost-related frost buildup restricts airflow across the evaporator, so the refrigerator compartment cannot get enough cold air. Catching it early helps prevent food spoilage and reduces strain on the compressor.

To put the bottom grille (base grille) back on your Whirlpool WRX735SDHB00 bottom-mount refrigerator, line up the grille’s end tabs with the openings near the front leveling legs, then press along the ends until it snaps fully into place. Use any retaining screws if your grille has them.

Before you start

• Unplug the refrigerator or switch off power at the breaker (recommended if you will be working near wiring).
• Pull the refrigerator forward a few inches for easier access.
• Remove the toe-kick area debris so the grille can seat flat.
• Confirm the grille is not warped or cracked.

Steps to reinstall the bottom grille

1. Position the grille: Hold it in front of the refrigerator base with the finished side facing out.
2. Align the ends: Match the grille’s end tabs/clips to the slots by the leveling assemblies.
3. Snap it in: Push inward at the left and right ends first, then press across the length until it sits flush.
4. Secure (if applicable): If your grille uses screws, install and tighten them snugly (do not overtighten).
5. Verify fit: Tug gently on the grille; it should stay locked and not rattle.

Quick troubleshooting if it will not stay on

• Grille won’t snap in: The tabs are misaligned with the leveling leg brackets; re-center and try the ends first.
• Grille pops off: A clip is broken or the grille is warped; replace the grille if the locking tabs are damaged.
• Rattling noise: The grille is not fully seated; press along the corners and center until flush.
• Door rubs the grille: The refrigerator may be out of level; adjust the front leveling legs per the owner's manual.

Why it matters

A properly installed base grille helps protect components at the bottom of the refrigerator and supports correct airflow around the machine compartment, which helps cooling performance and reduces noise.

What you see	Most likely cause	What to do
Grille sits crooked	One end not clipped in	Reinstall, snapping ends first
Grille falls off	Broken tabs/clips	Replace the grille
Grille vibrates	Not fully seated	Press until flush

Whirlpool refrigerators typically last 10 to 15 years on average, and many run closer to 20 years with good maintenance. For your Whirlpool WRX735SDHB00 bottom-mount refrigerator, steady temperatures, clean airflow, and timely part replacement are the biggest factors that extend service life (see the owner's manual).

Typical lifespan and what changes it

Most bottom-mount refrigerators fall into a similar life range, but real-world lifespan depends on usage and care.

• 10 to 15 years: common average for many households
• 15 to 20 years: common with consistent cleaning and stable conditions
• Shorter lifespan happens when the unit runs hot (dirty coils, poor ventilation) or has frequent door-opening and warm loads

Quick lifespan factors

Factor	Shortens lifespan	Extends lifespan
Airflow/heat	Dusty condenser area, tight cabinet clearance	Clean condenser area, good ventilation
Door sealing	Torn/warped gasket, doors not closing	Strong seal, doors aligned
Water/ice system	Old filter, low water flow, leaks	Regular filter changes, leak checks
Temperature habits	Warm food loads, frequent long door openings	Stable settings, quick door openings

Maintenance that most improves longevity

These steps reduce compressor run time, prevent icing, and protect the ice maker and water system.

• Vacuum dust from the condenser area and surrounding vents regularly
• Keep doors closing fully; avoid overloading door bins
• Replace the water filter on schedule; use the correct refrigerator water filter EDR4RXD1
• Watch for slow water dispensing or hollow ice cubes; those are early flow restriction signs
• Keep the freezer drawer sealing evenly; frost buildup often points to an air leak

Why it matters

A refrigerator that runs hotter or leaks air works harder; that increases wear on the compressor, fans, and controls. Simple upkeep helps your WRX735SDHB00 cool more efficiently and reduces the chance of expensive failures.

Yes. A bottom-mount refrigerator like the Whirlpool WRX735SDHB00 is a great choice when you want everyday convenience; the fresh-food section sits at eye level, so you reach the most-used items without bending as much as you do with a top-freezer design.

What you’ll like about a bottom-mount design

• Easier access to fresh foods (less bending for milk, produce, leftovers)
• Wider refrigerator compartment layout that’s easy to organize
• Freezer drawer can hold bulky items (pizza boxes, bags of frozen food)
• Often includes features like in-door ice and water on many models

Trade-offs to consider

Bottom-mount refrigerators are “good” for most kitchens, but they do come with a few common compromises.

• Freezer access can take more bending and pulling out the drawer
• Freezer organization depends on baskets and dividers (items can stack)
• They typically cost more than basic top-freezer models
• Door seals and drawer alignment matter more; small gaps can cause frost or warm spots

Quick comparison

Feature	Bottom-mount (WRX735SDHB00 style)	Top-freezer
Fresh-food access	Best	Good
Freezer access	Good (drawer)	Best
Organization	Strong in fridge	Strong in freezer
Typical price	Higher	Lower

Why it matters

Most households use the refrigerator section far more than the freezer. With a bottom-mount layout, the items you grab all day stay in the most comfortable reach zone, which improves usability and can reduce door-open time.

Tips to keep performance strong

• Keep doors closing tightly; replace worn gaskets if you feel air leaks (for example, Whirlpool refrigerator door gasket (gray) W10830274 or refrigerator freezer door gasket (gray) WPW10714545)
• Change the water filter on schedule to protect water flow and taste (see refrigerator water filter EDR4RXD1)
• Use the cleaning and temperature recommendations in the owner's manual
