Whirlpool WRX735SDHZ Refrigerator: Freezer Door Seal... | appliancefaults.com

Technical Background:

The Main Control Unit (MCU) manages the defrost cycle and door heater (if equipped) based on temperature sensor readings. Voltage paths from the MCU supply power to the defrost heater, defrost thermostat, and door heater. A faulty seal allows warm, moist air to enter, causing the compressor to run longer and generating excess frost.

Symptoms:

The homeowner observes gaps in the freezer door seal of their Whirlpool WRX735SDHZ refrigerator, accompanied by frost buildup inside the freezer compartment.

Possible Causes:

Damaged or Deteriorated Door Seal
Door Misalignment
Excessive Frost Buildup
Freezer Overloading
Improper Door Closing
Faulty Door Heater (if equipped)

Solution:

1

Visually inspect the freezer door seal for tears, cracks, or hardening. Replace if damaged. A new seal costs approximately $50-$100.
2

Clean the door seal with warm water and mild detergent. Dry thoroughly. Use a soft cloth to avoid damaging the seal.
3

Check the door alignment using a level. Adjust the hinges if needed to ensure the door is flush with the refrigerator cabinet. A 5/16-inch nut driver is typically used for hinge adjustments.
4

Manually defrost the freezer to remove any excessive frost buildup. Ensure the defrost drain is clear. Use a turkey baster and warm water to clear any ice blockage in the drain.
5

Test the door heater (if equipped) for continuity using a multimeter. It should typically measure between 100-300 ohms. Replace if open or shorted. Disconnect power before testing.
6

Ensure the refrigerator is level. Use a level on the top surface and adjust the leveling feet as necessary. An adjustable wrench may be required.
7

Confirm the door closes and seals properly. Place a dollar bill between the seal and the cabinet and try to pull it out. The seal should hold it firmly.

Safety Warning:

Disconnect power to the refrigerator at the breaker panel before performing any repairs. Use proper Lock-Out/Tag-Out (LOTO) procedures to prevent accidental power restoration. High voltage components are present in this appliance; exercise caution.

Prevention:

Clean the door seals regularly (every 3-6 months) with warm water and mild detergent. Avoid overloading the freezer, which can prevent the door from closing properly. Inspect the door seal for damage annually and replace as needed.

Expert Tip:

Some Whirlpool refrigerators have a diagnostic mode. To enter service mode on some models, press and hold the 'Door Alarm' and 'Temp Down' buttons simultaneously for 3 seconds. This can allow you to force a defrost cycle to test its components.
