Refrigerator section was getting warm, due to frosted coil in freezer section.
I actully did two replacements at one time. I replaced the defrost heater and thermostat plus the adaptive defrost. I chose to replace both as I had no way of diagnosing which was the problem (excecept for the heater of course). Firstly make sure you keep track of where the screws come from when you disassemble the plastic and metal panels. Once the coil is defrosted in the freezer, it is easy to remove the panel covering the coil, then it is very easy to remove and replace the thermostat and heater. Just be careful to route the wires the same way as the origional configuration and do not force anything near the coil evaporator coil as it is only aluminum. The adaptive defrost component is simple to change out, the hard part is to CAREFULLY remove the plastic panels under which is located the adaptive defrost. Again, remember where the screws go and how the parts go together. The video for changing out the adaptive defrost is extremely helpful. Patience, patience and more patience is required when fooling with the bits of plastic. Allow plenty of time to do the project and do not rush. All of the parts go together like a jig saw puzzle but are very logically assembeled. Good Luck, I saved about $300 in doing these fixes my self.
I pulled down the wire around the glass cover. . . Released on end of the wire from its holder being careful to not let the glass cover drop. Unscrewed the bulb and replaced with replacement. Easy, easy.
Internal light did not come on each time the door was opened.
After disconnecting the electricity. I followed the instructions as indicated in the "HOW TO" article on the website. I used a steel putty knife and pried the light switch out of its retaining hole. I worked the right side the most since this is the side with the retaining clip. After I removed the switch I transferred the two electrical outlets to the new switch and easily snapped it into place. Engaged the electric power and tested the switch.
Verified the Freezer was coils behind the back inside panel were frozen. Read where this is typucally the ADC pcb in this model. Ordered the ADC through Part Select at a discount. About $65. Manually defrosted refridge for 2 days until part arrived. Replace ADC in the upper back right side of the frig. Turned power back on. Placed a thermometer in the Freezer and Fridge. Allowed a full day for temps to settle in -5F FZ, 38F FG. Restocked fridge. Caution - Drip pan is not big enough when manually defrosting. Suggestion - Always have a back up fridge in the garage or basement. JennAir has been the best looking and worst refridge I have ever had. Qty 2 ADC's and Qty 1 compressor start modules in the first 9 years of its life. I have $500 garage refridge that is 15 years and never had a single issue. Last Jenn Air for me. Wanna buy one?
Freezer coils completely ice up monthly, Refrigerator side gets warm
After having to defrost the coils monothly about 4 times with a hairdryer, i decided to buy this part. Success so far!
First you have to remove the top plastic panel which is difficult to figure out, there are clasps holding it towards the back, so make sure you get those taken care of. The you have to unscrew much of the top components as one whole unit. you don't have to completely remove and i didn't see how it could be done. You just need enough room to get over the top of it and to the back of the fridge. The adaptive defrost assembly is in the back right and you have to take it out by going over the top of this entire top fridge component (hence the parital removal of it.) You take it out of it's sqaure little box (it may be screwed in through the bottom of it's tray, so remove the screw first) then "Unclip" the wire harness. The mounting screw configuration didn't match on mine, nor did the screw themselves, so i just reclipped the new defrost control assembly into the harness, set it into the tray, and screwed everything back together.
It's a little difficult the first time because parts don't remove as easily as you would think, but doing it again, which may be required, will be much easier.
In refrigerator comparment removed control cover. Simply pull it forward and it drops down. Remove four screws holding controls to inside top of refrigerator. Remove two screws holding circuit board unit (adaptive defrost timer). Unplug electrical connector and removed the part. Put new part in by removing top cover and part so the electrical plug could be installed easier. Install top part cover and screwes back into contols panel. Reinstall tyhe control panel and cover.
removed top panelwith three srews and disconnected wire horness brought down complete panel and replaced adaptive defrost timer,I learn this going on magtag web site on trouble shooting chart
Looked up model number online. Ordered part from Part Select.com. Removed 5 screws from top of inside of fridge. Removed old Adaptive Defrost Timer. Plugged new part in and reinstalled the other parts. Local appliance company quoted me $250.00 to repair my fridge. I had less than $70.00 bucks in doing the repair myself.
removed the 2 screws that held the panel in place, had to reach up and push on locking tabs to lower trhe front of the panel. was able to then push on the locking tab of the switch to release it. removed the wires, replaced them onto the new switch, and snapped the switch into place. the rest was reverse of the uninstall process.
Freezer side frozen while refrigerator not cooling at all
The Jenn-Air Refrigerator is approximately 8 years old and this is the 2nd time I have replaced the defrost assembly board. The first time, it cost me $250 - but this time was much cheaper using partselect.com.
The most difficult part of the repair was removing the overhead light assembly in the refrigerator compartment. The defrost assembly board is in the back right hand side of the refrigerator compartment -above the light assembly. First, you must remove all the screws which light assembly cover, then remove the screws in the back right corner which hold the defrost assembly board in place.
Once the screws and housing were removed, I unplugged the old board from the wire harness and removed it from the refrigerator. I then plugged in the new board and put all screws back in to hold it in place. I then put the light assembly cover back in place. Total repair time was approximately 45 minutes because I had to figure out how to remove the light assembly. However, it was well worth it to save the money and know how to repair it in the future. Given the track record with this Jenn-Air, I'm sure it will have to be repaired again.
Thanks to partselect.com for a great site and parts description.
