Whirlpool WRX735SDBM02 refrigerator Parts

For the Whirlpool WRX735SDBM02 bottom-mount refrigerator, we leave the cardboard-like bottom cover in place. It is a protective air-flow and component shield for the condenser area; removing it can reduce cooling performance and expose wiring and moving parts.

What that “cardboard” piece is

On many Whirlpool refrigerators, the bottom panel is a fiberboard-style or thin composite cover that functions like a service shield.

• Directs airflow across the condenser coil and compressor area
• Helps keep dust, pets, and debris away from electrical components
• Reduces the chance of accidental contact with hot or moving parts
• Lowers noise by acting as a simple sound barrier

When you would remove it (and when you would not)

You typically remove the bottom cover only for service tasks, then reinstall it.

Task	Remove the bottom cover?	Put it back afterward?
Routine operation	No	Not applicable
Cleaning condenser area	Sometimes	Yes
Diagnosing a fan or compressor noise	Sometimes	Yes
Replacing a part in the machine compartment	Yes	Yes

Safe, practical steps if you need access

1. Unplug the refrigerator (or switch off power at the breaker).
2. Pull the unit out carefully to avoid kinking the water line.
3. Vacuum dust from the rear and underneath; avoid bending coils or hitting wiring.
4. Reinstall the cover exactly as it was so airflow stays correct.

Why it matters

That bottom cover is part of how the refrigerator manages heat. If airflow is disrupted, the compressor can run longer, temperatures can drift, and you can see more dust buildup around the condenser.

Whirlpool refrigerators typically last 10 to 20 years, with 12 to 15 years being a solid average for normal household use. For your Whirlpool WRX735SDBM02 bottom-mount refrigerator, consistent maintenance and good airflow around the cabinet are what most often determine whether it lands closer to 10 years or closer to 20.

Typical lifespan and what to expect

Most refrigerators follow a predictable pattern: early years are mostly trouble-free, then wear items start showing up, and later years may bring higher-cost sealed-system or control issues.

Age of refrigerator	What’s common	What we usually recommend
0 to 5 years	Minor adjustments, occasional ice/water issues	Keep coils clean, replace filters on schedule
6 to 10 years	Ice maker, sensors, door seal wear	Repair is usually worthwhile
11 to 20 years	Higher chance of major cooling or electrical issues	Compare repair cost vs. overall condition

Maintenance that extends life (most impact)

These steps reduce compressor run time, prevent frost and moisture problems, and help temperatures stay stable.

• Keep condenser area clean and ensure ventilation space around the refrigerator
• Keep doors closing tightly; fix gaps and torn seals promptly
• Replace the water filter on schedule to protect the water system
• Avoid overpacking; blocked airflow causes warm spots and longer run times
• Keep freezer and fresh food temps in the recommended range (check your WRX735SDBM02 owner's manual)

Parts that commonly affect longevity on this model

If performance drops, these are common “life-extending” repairs because they restore proper temps, sealing, and ice production.

• Refrigerator water filter EDR4RXD1 (water flow, taste, dispenser performance)
• Refrigerator ice maker assembly WPW10300024 (no ice, small cubes, intermittent harvest)
• Refrigerator thermistor W10316760 (temperature sensing and cycling accuracy)
• Whirlpool refrigerator door gasket (gray) W10830274 (warm temps, moisture, frost)

Why it matters

A refrigerator that runs longer than it should (due to dirty coils, air leaks, or bad temperature sensing) puts extra strain on the compressor and control system. Keeping temperatures stable is the simplest way to push lifespan toward the high end of the 10 to 20 year range.

On a Whirlpool WRX735SDBM02 bottom-mount refrigerator, a leak from the bottom is most often caused by a clogged or frozen defrost drain that overflows into the fresh food section and then runs down to the floor. We also see leaks from the water filter or ice maker water supply lines.

Quick checks (start here)

• Unplug the refrigerator or turn off power at the breaker before removing panels.
• Look for a sheet of ice or standing water under the crisper drawers; this points to a defrost drain issue.
• Check the water filter housing area for drips; reseat the filter and inspect the O-rings.
• Inspect the water line connection behind the unit and the line feeding the ice maker.
• Confirm the doors close fully; warm air intrusion increases frost and can worsen drain freezing.

Most common cause: frozen or clogged defrost drain

When the defrost drain is blocked, defrost water cannot flow to the drain pan; it spills into the compartment and leaks out the bottom.

What we do to clear it:

• Remove food and pull out lower bins/drawers.
• Melt visible ice with warm air (hair dryer on low) or warm towels.
• Flush the drain opening with hot water using a turkey baster until it flows freely.
• Clean the drain pan area if accessible and dry any pooled water.

Water system leak points (filter, dispenser, ice maker)

If the leak happens during dispensing or ice production, focus on the water circuit.

Symptom	Most likely area	What to do
Drips near filter compartment	Water filter not seated or damaged seal	Reinstall or replace the refrigerator water filter EDR4RXD1
Puddle appears after ice maker runs	Ice maker fill tube or supply line connection	Inspect tubing and fittings for cracks or looseness
Slow drip at random times	Water line connection behind fridge	Tighten fittings; replace damaged tubing

Why it matters

Bottom leaks can damage flooring and also create ice buildup that restricts airflow, which makes temperature control harder and can lead to warm spots in the refrigerator.

For model-specific access steps and panel locations, follow the owner's manual. If you need to order the correct replacement parts for WRX735SDBM02, use the parts list for this model or search by model on Sears PartsDirect.

The most common Whirlpool refrigerator problem is a cooling complaint: the fresh food section gets warm, the freezer temperature drifts, or the unit runs constantly. On the Whirlpool WRX735SDBM02, the most frequent root causes are airflow and temperature-sensing issues (dirty condenser area, evaporator fan problems, or a failing thermistor).

What we see most often (symptoms)

• Refrigerator section warm but freezer still cold
• Freezer too warm and ice production slows or stops
• Refrigerator runs longer than normal or seems to never shut off
• Unusual fan noise (rattling, buzzing, or a loud hum)
• Frost buildup that blocks airflow to the refrigerator section

Quick checks you can do first

1. Confirm temperatures: set refrigerator to about 37°F and freezer to about 0°F.
2. Check airflow: make sure vents inside the compartments are not blocked by food packages.
3. Clean the condenser area: dust buildup reduces heat removal and causes poor cooling.
4. Listen for the evaporator fan: when the doors are closed, you should typically hear a steady fan sound from the freezer area.
5. Look for frost patterns: heavy frost on the back freezer panel often points to a defrost or airflow problem.

Parts that commonly relate to “not cooling” complaints

If basic checks do not restore normal temperatures, these model-matched parts are common suspects:

Problem pattern	Common cause	Model-matched part to consider
Temps swing, food freezes or warms intermittently	Temperature sensing issue	Refrigerator thermistor W10316760
Warm refrigerator section, weak airflow	Evaporator fan airflow issue (fan/blade)	Refrigerator fan blade WP67006337
Ice maker stops or makes little ice (with correct freezer temp)	Ice maker failure	Refrigerator ice maker assembly WPW10300024
Lights or door-related functions act up	Door switch issue	Refrigerator light switch W11396033

Why it matters

Cooling problems are usually progressive. When airflow is restricted or temperature feedback is inaccurate, the compressor and fans run longer, temperatures drift, and food quality drops faster. Catching the cause early helps prevent bigger failures.

Helpful model resources

• Use the WRX735SDBM02 owner's manual for temperature settings, control features, and operating checks.
• If you see a code or suspect a control issue, use Whirlpool refrigerator error codes to narrow the failure.
• When you are ready to order model-specific replacement parts, start with the parts list for WRX735SDBM02 or search by model on Sears PartsDirect.
