Z18SSB Frigidaire Refrigerator - Instructions

After silencing the alarm, it seemed to be running as normal without any unusual noises, but food was starting to thaw from the top shelf on down and condensation was dripping from the roof. We were able to place most of the food in 2 large ice chests and then the rest in the freezer compartments of 2 fridges we have in the house. I then turned down the temp dial to the coldest setting and let it run for an hour or so; no change.

After researching on the internet, it sounded like our symptoms could be pointing to a defrost timer issue. I pulled the freezer away from the wall, located the timer and used a large screwdriver to slowly advance it. While doing this, at one point I could hear the compressor kick in. I pushed the quick freeze button and let it run for a while. When I checked it in a few hours, the alarm light had gone out and water that I had placed inside was frozen. We took a chance and put the food we placed in the ice chests back in the freezer. Everything was fine several hours later.

I ordered a new defrost timer, it arrived in a couple of days, and replaced the old one with it in a matter of minutes by disconnecting the wire harness from the old timer, removing the 2 screws holding it onto the bracket, screwing the new timer to the bracket, reconnecting the wires harness, and done. It's been a week or so and no problems.

slid freezer away from wall - - bottom left hand corner was the frost timer - - removed two philip head screws - - unpluged timer and installed new timer - - turned timer past first click to a little past second click (freeze cycle) - - slid freezer back FINISHED - - YOU GUYS ARE THE BEST WITH YOUR WEB PAGE AND HELP!!!!! Next day freezer was at 0

Bought a new
capacitor.

Watched the defrost timer to see that it wasnt moving, looked the part number up on your site and it even had a picture of it so I knew I was getting what I needed, ordered it when it came I took out the screws holding it in place unplugged old one and plugged in the new one, freezer works like new... :))

One day my freezer's overtemp light/warning came on. I knew the compressor was working properly (as it was still running) and that there were no leaks.

I was able to research about how this freezer worked and learned of this mechanical timer on the back of the freezer. It turns on/off the defrost mode of the freezer.

I manually turned the knob on the back to see if I could get the freezer to defrost. Turns out the timer was no longer working and when I manually ran the defrost, the freezer started to freeze again.

I just replaced this part and my freezer is working like norma.. Simple as all it takes is a few screws and you are done.

I knew that the problem had to do with the timer so I went online and looked at the schematic diagrams on Partselect and identified the part that should handle the problem. I ordered it and it arrived fairly quickly. It took a Phillips screw driver and about fifteen minutes to remove the old part and replace it with the new one. Very easy repair. It is working as it should now.

This was a simple job. Raised the flap in the back that houses the compressor, removed the wire that holds the relay, pulled out the old relay and pushed the new one on. Replaced wire holder and that was it. Plugged it frig and freezer is at zero and lower compartment at 35. As easy as brushing your teeth!

I located the part that was the culprit as it had buzzed very much before quitting. This is an easy removal as the part is in a two prong jack and just needs to be carefully removed with the new part inserted back in the jack provided. The refrigerator works fine now, but the run capacitor will still buzz on start up of the compressor. I do hope this is normal in this model? anyway it runs fine mow. Thank you.

Removed two screws and wire harness from old motor. Put in new motor and connected wire harness.

First, I unplugged the appliance. Safety, first.
Than I removed the shield which was held in by screws. This covered the fan, thermometer.
The defrost thermostat was taken out, with a little extra force. The wires on the defective part were no longer attached to the part. The instructions were easy to follow in replacing the defrost thermostat. I stripped the coating on the wire, attached it with the enclosed electical bugs. The assy was able to follow, and the part went back on. The refrigerator is working perfectly. I couldn't have done it without the help in diagnosing the problem and with the speedy delivery of the new part. Thanks for all your help and the ease of the installing the new part!

Looking on-line at your diagnostic for this problem, I saw the most common part to cause this problem was the start capacitor, so I purchased one & installed it with no positive outcome. I then purchased the next recommended part which was a defrost timer & installed it with no run again. Frustrated, I looked at another diagnostic web site that claimed 90% of the time the problem is caused by the cold control thermostat. I tested mine and it tested bad, so I bought a control elsewhere, since your site did not list a PN for that device. I installed the new control and the freezer started up correctly. Looking at the wiring diagram for these parts, I see the start capacitor and defrost control are downstream of the cold control thermostat, and to my mind should have been the first part recommended for testing versus the parts I bought, so I am somewhat disappointed in the diagnostics on your site, where I spent about $80 for parts that were functional.

The site offers a video for this part which worked perfectly. In addition to replacing the part, since the cardboard panel was off, we also cleaned all the dust off of the coils which someone recommended to do annually.

Replaced defrost thermostat and defrost timer on my commercial Kelvinator freezer. Took out screws inside freezer compartment that hold panel at top inside freezer.Once the screws were removed I pulled out the thermostat dial so the panel was free to drop down and expose coils to the freezer that were located in the top rear of the inside freezer compartment.The defrost thermostat was located on the top of the coil to the top left as you face the inside of the Kelvinator KFS220RHY1 freezer. Very easy unplug old and plug in new defrost thermostat. Also replaced timer located in the back side of the freezer down near the middle of the bottom of the freezer near the compressor. There were two nuts holding the timer in the back of the freezer once I took those out I just unplugged the old timer and plugged the new timer in ....very simple fix. I have only run my freezer for a week since I replaced both parts but so far all is working well.

Removed old thermostat and replaced. really easy.

Removed the old defrost timer by removing 4 screws on the holding bracket. Disconnected the wire harness. Reconnected the wire harness to the new part. Installed the new part with 2 screws on the top of the molded bracket. I am a 67 year old woman... easy-peasy. (the defost timer is located in the bottom left rear of the freezer.
