How do you install a 5303918475 adaptive defrost control?

Hello;

My name is Peter. I am a retired field service refrigeration technician.

There are no fuses in refrigerators. Individual component failure acts a fuse.

You are locked into defrost.


PART NUMBER: 67004704 - Cost: $116.00
This is located in the upper right inside your control box.
This replacement adaptive defrost control board (part number 67004704) fits several models of side-by-side refrigerators. The adaptive defrost control board starts and stops defrost cycles as the temperature of the evaporator rises and falls instead of on a set schedule.
Shut off the circuit breaker for the refrigerator before beginning this repair. Also make sure you're well grounded (Rub hands on bare metal), because electronic components can be damaged by discharges of static electricity. The board installs behind the digital display in the control panel. Procedures for removing the existing adaptive defrost control board and installing the new one vary among models.

21.3 ohms is just fine for a defrost heater. this heater is low wattage since it is an adaptive defrost. you could have problem with temperature sensor since you have replaced the board already.

tnx for using fixya,

You most likely have a defrost problem. Put the unit into defrost. Unit uses an Adaptive Defrost Control

to put this adaptive defrost style of fridge into defrost, short with a small screwdriver between L1 and test on the adaptive defrost board, wait 3 seconds and you should hear a "click" noise from the relay and the fridge will shut off and go through a defrost cycle.

The newest defrost feature in modern fridges is the electronic adaptive defrost control board.

Hi and welcome to FixYa, I am Kelly. Not defrosting can be caused by component failure.
Those components being:
1. The adaptive defrost control (Item 13 this link) http://www.appliancepartspros.com/partsearch/model.aspx?model_id=48135&diagram_id=665424#d665424
You can manually initiate a defrost cycle by shorting L1 to test on the adaptive defrost control board for 3 seconds. You should hear a relay click, the compressor and evaporator fan will shut off and the defrost cycle will start. If after about 45 minutes the defrost cycle does NOT terminate then there are other problems. See adaptive picture here for terminal locations: http://www.applianceaid.com/image/mayadaptive-defrost2.jpg
2. The defrost element is open. ( Item 12 this link)
http://www.appliancepartspros.com/partsearch/model.aspx?model_id=48135&diagram_id=628782#d628782
You can check this by reading resistance between the yellow and the White / Black wires on the adaptive defrost connector. No resistance = open element.
3. The defrost thermostat. (Part of Item 12 assy above)
With power off this is checked for 340K ohms or less reading between White Black and Red wires on the adaptive defrost control wires.
4. A slow or NOT running evaporator fan. Resistance of the motor winding is checked from the BLUE wire on the temp control to the orange wire on the adaptive defrost control. It will read around 180 Ohms.
SCHEMATIC: http://www.applianceaid.com/images/mayadaptive-defrost.JPG
The only other thing that can cause problems is a clogged evaporator drain. If it is defrosting though it will cause water to leak out the door of the freezer compartment at the bottom left.

It is going to take a meter to sort out which of the 3 components has failed. Let me know if you need anything more.

Thanks for choosing FixYa,

Kelly

I really believe your adaptive defrost located inside the fresh food compartment and inside the control panel is defective. It puts your refrigerator on a timely defrost and if defective this problem you listed in your post happens. Yes we may need to also check the defrost heater and defrost thermostat but with my experience with that type of Adaptive Defrost Control is famous for its failure.
ADAPTIVE DEFROST CONTROL Part Number 61005988 You can find it located on two of my websites. Some models like yours came with a Defrost Timer. We will need just look inside the control panel and see for sure. Here is a photo of the Adaptive defrost. If you should need to contact me please send an email or try to answer here. Problem is I don't get notifications when someone comments. [email protected]

Please rate and ask me as much as you like. Thank You, Sea Breeze

pulse and adaptive def actuall work in tandem with one another. what happens is the computer will put the refrig into a short def cycle and test how long it takes the termination switch to open this determines when it is time for the unit to go into a full term def the next time. adaptive defrost looks for the number of door openings and how long it takes for the def termination switch to open during a regular defrost. most units will go into def every -12 hours with adaptive if the conditions are right it can go as long as 2 or 3 days between def cycles. both systems are very relaible and trouble free. the pulse defrost is available on higer end electronic control refrig and is also adaptive defrost system as well. whirlpool also has adaptive defrost only available on their midline units as well as some higher end manual control units.\\
sorry for the defrost class peyton..

two things to check, defrost heater, defrost limit switch, if ok, install new adaptive defrost control.

you cannot do this
just check the defrost heater and the bi metal, if they check good then the adaptive defrost control is bad
