My Whirlpool MOD# W4TXNWFWQ03 SER# VS24448883 The freezer ices up, fridge not cold. the freezer coil is build up ice but the fan is running. Where the defrost timer located & the part number for this model? How to test if the defrost timer working or not? Thanks you very much!
Answer Hello Net,
The defrost timer is located in the control area inside the fresh food compartment. The replacement part number is 482493. The loose black wire should be connected to the second terminal which is labeled terminal number 1. To test the old timer, turn the small knob on the bottom which can be seen through the small dime sized opening in the units' ceiling and turn it clockwise until you hear a loud click. The unit should be in defrost from 20 to 30 minutes and start back up. While it is in defrost, you can check for voltage at the defrost heater and/or defrost bi-metal. If voltage is there and the timer cycles back out of defrost on its' own, it is good.
My refrigerator's freezer is freezing up & causing refer to be warm. Should I replace both Defrost timer (#482493) & Bimetal Defrost (#4387503)?
Answer Hello Two4qt. 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
At what location on the tube do you attach the defrost thermostat? Thank you, Dave
Answer Hello Dave,
The defrost thermostat clips onto the large line that comes into the back wall of the freezer compartment about halfway between the back wall and the evaporator coil.
Will defroster #4387490 work for the fridge model # I listed above?
Answer Jeremiah, model ET4WSKXT06 does not pull up in our systems. Please recheck that model number. For the other given model, ET14JKXJN00, the defrost thermostat 4387490 is the correct replacement and will work on that product. Thanks!
What's the difference in the Bi-Metal Defroster element for my frig/freezer?
Answer Hello Jim! I am showing only one heating element and one bi metal. The bi metal 2211224 is the defrost thermostat which senses the temperature within the unit and activates the element when it is time to defrost and the heater is part number 2263749 which turns on and defrosts the appliance. Thanks!
I woould like to know the technncal speficication about AP3108445, I have a 2183073.
Answer Hello Freddy. The limit on the bi-metal is 6.7-14.5C. According to the part number you supplied, 4387490 is the replacement Bi-metal. Hope this helps.
