What is the biggest problem in a Whirlpool refrigerator?
The most common “big” problem we see in Whirlpool refrigerators like model WRX735SDBH00 is a cooling issue: the fridge warms up, temperatures swing, or food freezes in the fresh food section. These symptoms usually trace back to airflow, defrost, or temperature-sensing problems rather than the sealed system.
Cooling complaints typically come from a few repeat offenders:
- Dirty condenser coils causing poor heat release and warm temps
- Evaporator fan problems causing weak airflow and uneven cooling
- Defrost system trouble leading to frost buildup and blocked airflow
- Temperature sensor (thermistor) issues causing overcooling or warming
- Water/ice system faults (clogs or valve issues) that look like “no ice” or “slow water”
These steps solve a lot of “not cooling” calls without parts:
- Confirm the controls are set correctly (fridge about 37°F, freezer about 0°F)
- Make sure vents inside the refrigerator are not blocked by food packages
- Clean condenser coils and verify the condenser fan is running (if equipped)
- Listen for the evaporator fan in the freezer; it should run when the compressor runs
- Check door seals for gaps that let warm, moist air in
If basic checks point to a component problem, these model-matched parts are common solutions:
| Symptom | Likely area | Example model-matched part |
|---|---|---|
| Temps swing, food freezes, or fridge warms | Temperature sensing/control | Refrigerator temperature sensor kit W10316760 |
| Lights do not respond consistently to door opening | Door switch circuit | Refrigerator light switch W11396033 |
| Water dispenser slow, ice maker weak fill | Water supply/valve | Refrigerator water inlet valve WPW10498990 |
For model-specific control settings, diagnostics, and operating tips, use the WRX735SDBH00 manual.
A refrigerator that cannot move air correctly or read temperature accurately will run longer, waste energy, and either warm food into the unsafe zone or freeze items in the fresh food compartment. Fixing the root cause protects food quality and reduces strain on the compressor.

Why is my Whirlpool WRX735SDBH00 ice maker not filling with water?
If your Whirlpool WRX735SDBH00 ice maker is not filling, the most common causes are a restricted water supply (shutoff not fully open, kinked line, low pressure), a clogged or frozen fill path, or a failing inlet valve. Start with the water supply checks, then move to the valve and ice maker fill tube.
- Confirm the household shutoff valve is fully open.
- Check the water line behind the refrigerator for kinks, crushing, or leaks.
- Dispense water at the door (if equipped); weak or no flow points to a supply or valve issue.
- If you recently changed the filter, reseat it and purge air by dispensing several cups of water.
- Make sure the freezer temperature is cold enough for ice making (typically near 0°F).
A restriction or failure at the inlet valve is one of the most frequent reasons an ice maker will not refill.
| Symptom | Most likely cause | What to do next |
|---|---|---|
| No water at dispenser and no ice | Supply issue or inlet valve not opening | Check shutoff, line, then test/replace valve |
| Dispenser works but ice maker won’t fill | Frozen fill tube or ice maker fill circuit issue | Thaw fill tube; inspect for recurring freeze-up |
| Slow fill, hollow cubes, small batches | Filter restriction or low pressure | Reseat/replace filter; verify pressure |
If the valve is suspected, the correct replacement for this model is the refrigerator water inlet valve WPW10498990.
- Check for a frozen fill tube: Look where the ice maker fill tube enters the freezer; if it is iced over, thaw it with warm air (no open flame).
- Verify water pressure: Most refrigerators need steady household pressure; low pressure can prevent the valve from opening fully.
- Rule out filter-related restriction: A mis-seated filter can reduce flow; the correct filter for this model is the refrigerator water filter EDR4RXD1.
- Inspect for air in the line after service: Purging the dispenser helps clear trapped air that can delay ice maker refills.
When the ice maker cannot refill, it usually means the refrigerator is protecting itself from a poor water supply or the fill system is blocked. Fixing the restriction early helps prevent valve strain, slow ice production, and recurring freeze-ups.

What's the average lifespan of a Whirlpool refrigerator?
Most Whirlpool refrigerators last 10 to 15 years with normal household use. For your Whirlpool WRX735SDBH00, consistent maintenance (clean airflow, good door sealing, and on-time filter changes) is what most directly extends service life and helps prevent cooling and ice-maker issues.
A refrigerator’s life depends less on the badge and more on how hard the sealed system and fans have to work.
- Door seal condition (air leaks make the compressor run longer)
- Condenser airflow and cleanliness (dust and pet hair raise operating temps)
- Ice maker and dispenser use (more cycling means more wear)
- Water quality and filter maintenance (reduces clogs and valve strain)
- Room temperature and ventilation (tight cabinets trap heat)
Use these habits to keep WRX735SDBH00 running efficiently:
- Keep doors closing tightly; replace worn gaskets when they no longer seal.
- Change the water filter on schedule; a restricted filter can reduce dispenser flow and affect ice production.
- Keep vents inside the fresh food and freezer sections unblocked.
- Maintain stable temperature settings (avoid frequent large adjustments).
- Follow the care and cleaning guidance in the WRX735SDBH00 owner's manual.
| What you notice | What it often points to | Example part on this model page |
|---|---|---|
| Warm fridge or temp swings | Sensor/control or airflow issue | Refrigerator temperature sensor kit W10316760 |
| Water tastes off or slow dispenser | Filter restriction | Refrigerator water filter EDR4RXD1 |
| Frost, sweating, or poor door closure | Door gasket leak | Whirlpool refrigerator door gasket (gray) W10830274 |
| No water to dispenser/ice maker | Water supply or inlet valve issue | Refrigerator water inlet valve WPW10498990 |
Once a refrigerator starts running longer cycles to maintain temperature, energy use rises and key components (compressor, fans, controls) wear faster. Preventive maintenance keeps temperatures stable, protects food, and reduces the chance of expensive repairs.
