Defrost Thermostat Kit Specifications

If you find that there is excessive frost in your freezer, or the freezer will not defrost, you may need to replace the defrost thermostat. The defrost thermostat kit comes with the clip, leads, and heat shrink. To access the defrost thermostat for this repair, you will need to remove your freezer shelves, as well as the back panel of your freezer. To complete this repair, you will need a 1/4-inch nut driver, a set of wire strippers and crimpers, and a heat gun or blow dryer. Before you begin this repair, be sure to disconnect the power source from the appliance.

Does the defrost thermostat testing with an ohm meter have continuity in the non defrost state, or does it test open.
For model number 5303918214
PartSelect logo
Hi Bud, Thank you for the question, when it is cold it should read 0 for ohms, if it is warm, about room temp or warmer it should read infinity. Hope this helps!

Both sides are warm. Comp. Ohm out good,capacitor checks out good,fans work all the lights come on. The only thing I can think of is the defrost thermostat. Can I test that putting it in a glass of water to see if it opens and closes? Thanks for your time
For model number GS23HSZDC4
PartSelect logo
Hi Jose, Thank you for the question. The best way to do this is to remove the thermostat from the refrigerator so you can control the temperature of the sensor. You can let the sensor warm up to room temperature. With the sensor warmed up to room temperature the sensor should read approximately 6.2K Ohms at 68°F. With the thermistor submerged is a glass full of ice water, the sensor should be very close to 32°F which should read approximately 16.3K Ohms. If the values that you are getting are far off from these readings, then the sensor is bad and should be replaced. Hope this helps!

My fans are both working fine, however the coil on the freezer side is freezing up, and after thawing out completely and restarting the refrigerator side works great cooling properly for a few days until it freezes up again. Does this sound like the defrost thermo. Problem? Thanks
For model number FRS26R4CW3

Hello Dean, Thank you for contacting us. I suggest checking the following parts: PS469522 Defrost Thermostat Kit and PS2582247 Adaptive Defrost Control Board. You can test the parts with a multimeter. If you are unfamiliar with how a multimeter functions, we have videos available to assist you.

I only find frost in the fridge side and not the freezer side. Is it the problem with depfrost thermostat? Thanks for the attention.
For model number PLHS269ZCB0
PartSelect logo
Hi Andrew, Thank you for your question. I would suggest testing that part and also the control thermostat for your refrigerator as well. That part may be reading the wrong temperature inside of your refrigerator section. You may also just want to double check that the damper between your fridge and freezer as well. I hope that helps. Good luck with your repair.

For model number FRS23LH5DSR

Hi Terri, Thank you for your question. If both the refrigerator and the freezer section are too warm, there are some parts that you will need to check to see which ones are causing the issue. You will need to check the run capacitor, the evaporator fan motor, the defrost thermostat, the start device, the condenser fan motor kit and the temperature control thermostat. I hope this helps. Thank you and have a great day!

I got a code "high temp" , i replaced a thermostat, but still same faulted after 3 days running. Can you help me out?
For model number LFFU14F5HWC
PartSelect logo
Hi Thuan, Thank you for your question. If the high temp error code is flashing, there may have been a loss of electrical power. Make sure the power cord is plugged in. Check the electrical outlet for power. reset the the house circuit breaker if the outlet does not work. You may have a failed start relay or electronic control board. If this is the case, you may have to replace them. I hope this helps. Thank you and have a great day!

Defrost terminator (Thermostat) Was Stuck Open, Not Allowing Defrost, Heat Gun or Hair Dryer
PURCHASE:
Buy the terminator from the site because they sell the
terminator (thermostat) separately. Other places have it with the
wiring harness for more money. Changing it with the harness attached
is a very, very involved project. It includes removing the entire inner
liner of the freezer. The one the site sells requires only a simple
crimp splice and shrink tube.

TEST- If you have another freezer, ice or a friend's freezer available,
it is highly recommended that the new part be tested:
You will need an Ohm meter or a continuity tester. You can make one
very easily per instructions found on line.
TEST RESULTS-
a) At room temperature. An Ohm meter should show "Open".
b) After being in a freezer or submerged in ice water for at least an
hour, the Ohm meter should show "Closed".

I have installed hundreds of defrost thermostats. Very occasionally
one is defective. This project is a bit involved, so it is wise to pre-test.

HOW TO INSTALL THE DEFROST TERMINATOR (THERMOSTAT):
A) Prep
Remove Food & Be sure the freezer is warm.
Parts need to be pried upon & cold plastic breaks easily.
Tip: Put the screws in separate cups with labels. This will make
re-installing the many components easier.
Gather tools from the attached list.

B) Unplug Unit (Turning it off is not sufficient protection against shock.)

C) Remove Light Bulb (If it gets broken while working, glass may
get in the eyes.)

D) Remove Drawers (This is a bottom freezer unit with 2 drawers)
1) ) Upper Drawer:
a) Locate the 2 rectangular boxes covering the gears. They are
on each side, toward the rear of the drawer.
b) With a nylon spudger, push in the 2 clips on each box and
lift the boxes 1/4". They will stop at 1/4".
c) At the front of each track, remove 2 hex head screws with a
5/15" nut driver or a 1/4" flat bladed screwdriver.
d) Lift the front of the drawer a small amount while pulling drawer.
Lifting allows the 2 stops on the drawer to clear the track tabs.
e) When near the end of the drawer, lift the gear wheels slightly
to clear the track.
f) Put the drawer out of the way.

2) Lower Drawer With Front Door
*Leaving the door attached makes it easier to align the drawer when
reinstalling it later. It must be straight or the gasket will gap.
a) Put a thick towel on the floor, in front of the unit, so the door
can be laid upon in without scratching the handle or the floor.
b) Pull the drawer out and look at each track about 2/3 of the way
to the back of the freezer. You will see two long, white tabs.
c) Push a tab in while pulling the track slightly forward. Firm pulling
is required. Repeat on the other side.
d) Drag the towel and door out of the way

D) Remove the air grill at the top, rear of the freezer.
1) There is a clip in the center to push with a spudger.
It is easy to see in a photo of a replacement fan bracket.
2) On the right side, in the top row of square holes, is another clip
to press with a spudger while pulling that side of the grill out.
3) On the left, there is an air chute blocking the clip. It can not be
removed. With the right side pulled free, gently wiggle & pull the
left side until the clip clears & the grill is free to leave.

E) Remove the Ice Maker (Water does not have to be turned off)
1) Loosen, but do not remove, 2 screws above the ice mold.
2) Remove the one lower screw & put it aside.
3) Lift the ice maker & store it out of the way.
4) Do Not turn any wheels by hand, nor bend the bail wire.

F) Remove the Thermistor Cover (Upper Right Back Wall)
1) Gently squeeze the sides while pulling. Stop as soon as it's free.
2) Note how the thermistor & wires are installed in the cover &
thread the thermistor free.
3) Set the cover aside.

G) Remove The back Wall
1) Remove all visible hex head screws.
2) The back wall can now be removed.
3) Set it aside where it will not scratch any surfaces, as the edges
are a little sharp

H) De-Ice the evaporator with a heat gun or hair dryer.
Don't hold the heat source in one spot for long or wire insulation
or plastic components will be damaged.

I) Note the permanent ice ball in the upper-right corner.
The defrost thermostat is under this ball. Melt it with heat.

J) Install The New Thermostat
Hint- Take the thermostat to a hardware store to buy the
correct size shrink tube and crimp sleeves (butt connectors)

Refridgerator too cold...freezing food,could not turn down
First,read "how to" on the internet because the thermostat comes with no instructions and unplug refer. Second, remove food and lower rear panel. Third, pull off thermostat from tube it clips to, unhook wire harness,and cut wires.Fourth,add heat shrink tubing from store(that supplied is way too big) and connect wires with automotive connectors;shrink-seal tubing with flame.Fifth, re-install everything, and replace food.Sixth,use a thermometer to check temp and adjust controls as needed.

Freezer was cooling, but refrigerator was not cooling all the time. Evaporator fan was running, so decided to try new thermostat.
Followed install instructions on utube. Once freezer was empty, back panel was easily removed, and defrost thermostat was in plain sight, and easy to replace. Hope that solved my problem. Refrigerator has been plugged in for four days now, and is cooling properly so far.

After a power outage my refrigerator went warm & the freezer was cool.
I unplugged the refrigerator and removed the back panel in the freezer. Here the coils were covered in a block of heavy frost. The coils needed to defrost, I allowed this to happen of the course of a few hours. Once this was done I used the wire cutters, cutting the two wires to the thermostat. Doing this I checked the continuity & got no reading. Having ordered the part at a more than reasonable price including 2 day delivery, I was ready to complete the repair. Stripping the thermostat wires connected the the freezer unit, I attached the two wires color to color to the new thermostat. Here I needed to insert both ends into the connector (butt end), crimping both sides. Making sure each end I'd secure. Do this for both sets of wires. Placing the new thermostat back on the the cooper coil (on the same one it was removed from), put the freezer back in place. Here I only screwed in two, in case I need to go back in. I plugged the refrigerator back in turn the settings back to default or factory. Allowed the refrigerator to come back up to temperature for 24-48 hours. I did these and I'm glad to say my 12 year refrigerator is working just like before.
