Questions & Answers

For Whirlpool Air Diffuser Assembly (Part Number: OEM18047436)

Nhaps for Model Number ED5RHEXNL00

Problem: freezer normal, fridge very warm with ice buildup on the air damper, on the extremities of the vent grid. What I did: removed the big metal lid on the back of the freezer. The bottom part of the coil was all frozen, especially on the lower right side. Under the coil base sheer ice including through the hole that goes to the bottom of the unit. I thawed everything with a rounded object and hair dryer. What I am doing: Its working fine now, but I am on the lookout for any freezing again on the freezer side that will hamper air flow to the fridge. Temperature set to number 3 for both freezer and fridge. What is the cause of this problem? I cleaned throroughly the bottom coil of the unit. If the problem happens again I will check for the timer, heater, thermostat continuity. I have a digital multimeter Newcason model XC6013L, and I am wondering if I can test them with it.

Nhaps, With the issue that you are having, this would have been caused possibly by the door not closing all the way and allowing moisture to build up in the return air duct or maybe a slow drain. Make sure that the drain is flowing properly.

Joe for Model Number ED25TQXEN00

I had a problem with my freezer thawing out the frozen food and then freezing again. I replaced the defrost timer and it didn't fix it. I then replaced the cold control and it fixed the freezer problem. After a few months, we noticed the fridge was freezing food. I had to turn the fridge knob almost to the off position to keep things from freezing. It recently started freezing food in the fridge on the lowest setting. I just looked and the freezer knob was set to B. I put it to A on the lowest setting to see if that helps. The bar going from the knob to the damper control seems to be working fine. Does this appear to be a defective cold control or could it be the damper control? Thank you, Joe.

Hello Joe. Check the damper and make sure it is not broken. If not, you will need to replace the refrigerator cold control.

Hello Nate. It sounds like you may have a defrost problem with the unit. Check and see if there is any frost build up on the back wall of the freezer. If so, you will need to test the defrost heater and the defrost thermostat. They should read closed for continuity when cold. You can test this with a multi-meter TJMA-DMT3. I will include a link at the end to assist you how to use the multi-meter if needed. If both parts are good, you will need to replace the defrost timer. Once the problem is repaired, you will need to thaw out the ice on the coils before the unit will operate properly. http://forum.appliancepartspros.com/oven-repair-including-ranges-cooktops/4810-how-check-continuity-ohmmeter.html

Raymond for Model Number GD2SHAXLB00

My frozen food side is about 18 degrees F, but the fresh foods side has trouble getting below 50 degrees, and even after letting it alone for 24 hours it was only 46 degress. This is with the cold setting at 5 and the freezer setting at the warmest. Changing the freezer setting does open and close the doors in the diffuser. I ran hot water through the air return, and when I plugged in the unit again the defrost kicked on clearing all of the frost on the coils in the freezer side. The fan on the freezer side is running and blowing the air about what I would expect. The air flow through the diffuser doesn't seem effected by having the freezer door open or close. However, the air flow seems less than I would expect. Would this be the diffuser that is bad?

1 Answer

Raymond, If the evaporator coils were completely impacted with ice then it would be a defrost issue and you would want to do a continuity test of the defrost heater and thermostat and if either do not have continuity then it is bad. If there is a even frost pattern then you will want to pull the damper assembly and check to make sure that it is opening and closing.

Mark, You will want to check to make sure that the diffuser is operating properly as the unit does not have a fan behind the diffuser. You will want to check to make sure that there is no ice building in the diffuser area that would cause the unit to not have air flow. Also check to make sure that the fan in the freezer compartment is running.

Hello michaelj. 1. Unplug refrigerator or disconnect power. 2. Remove the mounting screw and wire channel from the top of the refrigerator compartment. 3. Remove the mounting screw and air baffle... more cover.4. Locate the air chute in the top of the freezer compartment. NOTE: For models in which the ice maker is turned for ice in the door, pull the ice maker forward and remove it from the product. 5. Remove the air chute mounting screw and cover. Style 1 - Remove the air chute. Then remove the air scoop from the baffle W10151374. Style 2 - Remove the air chute from the baffle. 6. Release the air baffle retaining clips from the freezer compartment and push the air baffle toward the refrigerator compartment.7. Pull the air baffle assembly into the refrigerator compartment and disconnect the wiring connector from the baffle motor.8. Reinstall the baffle assembly in the reverse order. 9. Plug in refrigerator or reconnect power.

Neil for Model Number Whirlpoo ed5chqxkb05 side by side

Freezer temp is great 0 and below, working fine, making ice etc. Refrigerator side air flow(diffuser) blowing cold air but barely(not enough to cool down that side). Is it stuck or a bad defuser? No frost behind the freezer wall. How do I find the diagram to take that difuser apart and replace it (suspecting thats the problem)? Whats the part # etc? Difuser screwed in there with a foam around it (access from fridge or freezer side?).. Thx

1 Answer

Hi Mario. How are your cavity temperatures ? Use a quality thermometer and put the controls at mid point. The freezer should be no colder then 0 to -2°. The fresh food should be between 37° and 47°. Adjust the controls one step per 24 hrs. Once you have established this, then you can remove the control panel complete assy. Look at all mechanical rods and adjustments for binding or breakage. The air diffuser part # is part # WPW10151374 that is located behind the rear left upper corner where the freezer air enters the cabinet. Thank You.

John for Model Number whirlpool ED5KVEXVB00

My refrig has a problem that it freezes some stuff on the top shelf. Bottles of water are okay but stuff like cream cheese and eggs freeze if put up there. I looked at the diffuser but it looks like it is just a pass through device. I've adjusted the controls but if I use the warmer setting to keep it from freezing that stuff the lower levels are too warm. Is this just a problem of design, food placement or possible defective part? Thanks for any info or ideas.

1 Answer

Hello John. If an item is placed need the damper, it will freeze due to the air coming into the fresh food is from the freezer. However, if it is freezing items at the front of the shelf, then the temperature sensor WP2198202 may be bad and will need to be replaced. Hope this helps.
