Customer Questions and Answers for Diffuser by Whirlpool

Manufacturer Part Number: W10814173

The Diffuser is an OEM part for Whirlpool refrigerators. It is a part responsible for evenly distributing the air flow within the refrigerator compartment, ensuring consistent and efficient cooling throughout the interior.

Causes of a bad Diffuser can include blockages or obstructions that restrict air flow, physical damage or cracks that compromise the diffuser's ability to distribute air properly, or simply wear and tear over time.

Symptoms of a bad Diffuser include:

  • Uneven cooling, with some areas being warmer than others 
  • Frost buildup or condensation in certain sections of the refrigerator 
  • Increased energy consumption as the compressor works harder to maintain desired temperatures 
  • Potential food spoilage due to inconsistent cooling

This OEM Whirlpool part is also compatible with Maytag, KitchenAid, Jenn-Air, Amana, Magic Chef, Admiral, Norge, Roper and some Kenmore models.

Questions & Answers

For Whirlpool Diffuser (Part Number: OEM17957334)

Mike for Model Number Kitchenaid ksf26c7xyy00

Refrigerator compartment was warm. Freezer compartment was fine. Found that the refrigerator compartment evaporator was frozen up. The bad thermistor was replaced. Now, I notice, the refrig temps bounce between 41 and 31, even during night times when door is closed. In the parts diagram for this model, I see another thermistor on the right side of the refrigerator compartment about half way up. What is its purpose? Does it have anything to do with the temp range? Or should I just not worry about the differences in the temp range?

1 Answer

Mike, it would be recommended that the temperature is checked in a couple of spots of the refrigerator as location can change what temperature is measured. If the temperature measured is in front of the air vent, it will show colder temps. If the refrigerator is set to 37°F, the temperature can increase up to 4°F before the refrigerator calls for cold air again. The thermistor W10316760 on the right wall is going to be the cabin thermistor.

Juli-Anne, unfortunately the model number provided is not matching the manufacturer database. If the model can be verified and posted in a new inquiry, the most accurate information can be provided. Generally speaking, you may want to inspect the temperature sensor to ensure that it is reading the correct resistance compared to the actual temperature. More than likely either the sensor is not registering the proper temperature or the control is not registering the reading from the sensor. Checking for voltage being supplied to the diffuser will also be a good way to verify if the control is sending voltage to the diffuser when needed.

Lori for Model Number GSF26C4EXW02

We have been having the clicking noises and EVERYTHING constantly frozen for months . I stumbled upon your website and am so happy I did. Our repair man said he'd be back in 3 days with the part and that was 2 months ago , he doesn't answer our calls and he was sent to us BY Whirlpool . This is the most frustrating , unbelievable waste of $ we've ever been through . The fridge is only 5 years old and every website says the part is no longer available. The part # is W10251516 , can you give us any advice on where to go next ? Either way we are so grateful to get any info on why this is happening , and also to see we're not alone with our so frustrating issue .

Linda for Model Number Whirlpool side by side I have part number W10251395

I have a Whirlpool side by side fridge. We had a constant loud clacking sound in the upper left side of the fridge side wall. The same thing happen about a year ago and the service guy replaced the Diffuser part number W10251495. Now the same thing is happening. The flap inside is making the clacking sound and you can see sticking, opening, clacking back. Is this the norm to have to replace this every year? Does this part also contain the flap that is causing the sound?

1 Answer

Thanh, When you remove the air filter from the center upper back of the refrigerator section, there will be 1 or 2 screws that hold the damper assembly in place. Remove the screw and pull out the damper.
