Bi-Metal Defrost Thermostat

Compressor Start Divice kit, I took off back lower panel with the 1/4 inch nut driver, on the compressor their was a wire hook that held the starter in place used my plyers to unhook, pulled the unit off plug the new unit in reappled the clip it was so easy I had to exame it severl to time to make sure that was all their was to it. put the cover back on and turn the refrigerator on and it has work great, I did not install the Bi-Metal Defrost Thermostat it was not needed.

WARNING: REPLACING THIS PART REQUIRES CUTTING AND SPLICING ELECTRICAL WIRES. RISK OF ELECTRICAL SHOCK OR FIRE. DO NOT ATTEMPT THIS REPAIR IF YOU ARE NOT EXPERIENCED WITH ELECTRICAL WIRING.

Part Info:
The bi-metal strip is clipped onto the evaporator coils and is designed to regulate the defrost coil temperature. If it is not functioning properly you may notice ice buildup preventing air flow (and preventing proper refrigeration), or more rarely the freezer side may get too warm during the defrost cycle.

Materials:
* Replacement bi-metal strip
* Wire cutters
* Wire strippers
* Wire nuts
* Electrical tape
* 10MM socket

Steps:

1: UNPLUG THE FRIDGE! If there is ice buildup, wait until the ice has melted. A box fan blowing at the ice will help melt it more quickly.

2: Remove the panel covering the evaporator coils. It's located inside the fridge, on the freezer side.

3: Un-clip the bi-metal strip from the evaporator coils.

4: Unplug the wires from the evaporator fan, defrost coil and bi-metal strip, then disconnect the main connector that is plugged into the rear wall.

5: Clip both wires to the old ( bad ) bi-metal strip. Cut close to the casing of the bi-metal strip so there are long wires to splice onto.

6: Strip 1/4 to 1/2 inches of insulation off of the ends of the wires ( depending on the size of the wire-nuts you use). Twist the bare wires slightly to prevent fraying.

7: Do the same for the ends of the wires on the (new) bi-metal strip.

8: Take the ends of the wires belonging to the (new) bi-metal strip and the wires coming from the main plug. Take the like-colored wires, and twist the bare metal ends together.

9: Twist on wire nuts, for both sets of wires. Make sure they are snug, with no bare wire showing.

10: Tape over the wire nuts with electrical tape. Tape over the wires nuts in a spiral fashion, completely covering the nut and both wires that are now spliced together. This will prevent accidental shorting.

11: Plug the main plug back into the rear wall of the fridge. Also re-connect the connectors to the evaporator fan and defrost coil. Make sure the clips on the connectors are snug to ensure a good connection.

12: Clip the new bi-metal strip onto the coils, in the same spot as before. ( Usually just after the small incoming copper tubing that connects to the coils, known as the expansion valve. That is usually the coldest spot on the coils during operation).

13: Replace the panel that covers the coils.

14: Plug the fridge back in... Now you fridge should defrost correctly. If it does not, your defrost coil could be burned out, or the control board could be faulty.

Unplug the refrigerator first,then Remove shelves and back inside cover from the freezer. Cut old bi-metal thermostat off and installed a new one. This fixed the problem. Ordered a new timer also which I didn,t need but installed it any way. On the fridge side ,top front, removed the knobs and cover, R&R timer, installed cover and knobs. Pay close attention to the instructions on where to put the black wire on the new timer. My refrigerator works great now. This was easy to repair if you are handy with electrical and mechanical repairs, if not get some help.

DISCONNECT POWER. Removed all shelves/baskets.Popped upper panel off (just clips in) Removed 6 screws in lower back panel ( 3 each side) slid panel in place but down. You can then easily see the defrost thermostat/defrost termination switch. Cut the wire connectors (pink n brown wire) stripped back wire, attached new defrost thermostat. Thermostat clips on. New thermostat ohm's at 5.5, old one was "open". Slid cover back up meeting the upper cover grooves. Screwed lower panel in. Put shelves etc back in. Plugged in. Turns on, put a bottle of water in freezer. Checked a while later, frozen. has been frozen for a week.

I have a side by side so in order to access the bi-metal switch I first had to empty out the freezer. The switch is clipped on to the top of the evaporator coil. I had to remove 8 screws to remove the back panel of the freezer compartment. The bi-metal switch was right there in plain view. There are two colored wires that come out of the switch. I tried pulling them out of the socket they were plugged into but gave up for fear of breaking something. I ended up cutting the wires and splicing them together. I used the plastic twist caps. I made sure when I closed everything back up that the open end of the caps were pointing down so no water can accumulate in them. It has been 3 days now and so far so good

I just removed a few screews and took the cover out of the ice box. Put my voltage meter to the refrigeator and realized the the unit was not defrosting...I then got the part number and entered it in on your web site. A few days later my part arrived. I put the part on and in just about 20 minutes I was up an running again...Thank you Part Select for fast and great service. I own 35 rental properties and having a online appliance parts store really saves me a lot of time and money.

Thank you

First I installed a defrost timer, (the old timer had burnt out contacts in it) It seemed to work for a few days, then went back to not comng out of defrost cycle, I then installed a defrost thermostat. It seems to be working better than before. I found out that maybe I wasn't running it cold enough. So I turned it up colder. Now it works ok for 2 - 3 days, then I check the Temp in the freezer and its up to 6o. So I manually reset the timer and it works for 2 - 3 days. Don't know what to do now to fix it.

I watched several video's on youtube that showed me how to replace the parts. Just Google "how to fix my freezer". I figured the only problem was the freezer Thermistor so I only replaced it. The refrigerator has one to. Instantly the freezer went back to Zero degrees and the defroster works fine after melting all the ice in the bottom. Make sure the drain hole is cleared. I ordered the bi-metal thermostat just in case but I don't need it. Be sure and position the thermistor down in the freezer rail on the right side just to where you can see it in the first opening and pull it back up out of sight and tape it to the wall where it comes through from the air baffle. It's important that it's 7.8 " down from the top of the freezer. Happy now, Freezer 0, refrigerator 37. This thing use to run all the time, I'm saying electricity now.

Removing the panels inside the freezer section was the most difficult ,because it is narrow,hard to fit your body inside compartment, in order to cut wires and to splice Bi-metal Defrost Thermostat wires (2 ) Watch the videos on the web site so you know where to start. First time I ever "repaired " a large appliance, saved me over $ 600.00 (that's what the people I bought the Refrigerator from wanted to charge me.) My parts cost 65.00 !!!!! My younger brother turned me onto the web site... , I'll be returning to the site and telling my friends about it. It's a total "rip off" what service organizations charge the general public these days from Car Dealer ships to the stores we purchase our appliances from. !!! Glad I still have my health and faculties to repair the essentials we have around our homes. !!!!

I followed your instructions , the only thing that was left out was that the freezer has a drain hole that had to be thawed out with a hair dryer,till the water went to the drain pan underneath the ref. your instruction were through enough, that's why I purchased the part from your company, I installed the part 2 days ago and its working like new again 23.00 for the part instead of 1200.00 dollars for another ref. thanks very much. 6 months ago I purchased the relay and compressor starter from your company at that time per your instructions I shook the compressor starter and like a light bulb it had something broke inside,I needed that thanks again oomk
