RT155HCD2 Frigidaire Refrigerator - Instructions

After some troubleshooting to ensure the thermostat and heating element were working, determined that the defrost timer was the problem. With the defective part, I was able to manually advance the timer to activate the defrost cycle, but it wouldn't do so on its own. Unplugged the refrigerator from the wall. Timer is located in the refrigerator compartment at the very top. The compartment houses the cooling thermostat, the light bulb and the defrost timer. Using 1/4" nut driver, remove 4 screws holding compartment cover to top of fridge. Lower a bit to access electrical wiring. Wiring harness can be unplugged to work on the timer away from the fridge which makes it a bit easier. Timer is mounted with 2 phillips head screws. Remove screws and unplug timer from wiring. Install new timer, plug in wiring, secure with the phillips head screws and remount entire compartment.

1. Disconnected electrical. 2. Removed upper console in refrigerator by removing 2 nuts. 3. Disconnected wiring from console. 4. Removed 2 screws from defroster timer part and pulled off from connector. 5. Replaced with new defroster timer and put everything back together. Thank you Steve for the U-Tube step by step video.

dismantled the top rear panel of the freezer and found I had the wrong part. Hand started the fan motor and it has been working fine since.

we removed the food from the freezer, disconnected the fridge , removed the cover, the evaporater fan was running, condeser fan was running, then we checked heater with multimeter and it was ok. next step we replaced the frostimer, and defrost thermostat . and then the refrigarater was working ok, problm was the frost thermastat damaged.

1 went with maj 69% said defrost timer. NO. 2 went with second choice run cap NO. 3 went with my thought, ( PTC Starter ) why not, most exp part. Fixed the problem.

Watched the video once. Removed four 1/4 inch screws with a nut driver unplugged the unit, took out two screws securing the timer. Replaced did all of this in about 10 minutes. It was "exactly" as the video showed and it's worked perfectly since the replacement of the faulty timer. I saved a $75.00 service call minimum and the part was more than likely cheaper from Part Select than from the repair facility. Although I'm a pretty good handy man, you would not need any experience to make this repair. The instructions are precise and the part fit perfectly.

tested the thermostat, cleaned the coils, checked seals all clean. defrost timer did not cycle so replaced it but issue not resolved. even though freezer was working while refrigerator was problematic, proceeded to open freezer panel. discovered that fan was not pushing cold air into refrigerator compartment due to ice build up in connecting tubes. cleaned ice and replaced panels to positive result

replaced the defrosting timer and saved a lot of $ by doing it my self.

Based on the diagnosis on this site I thought the 66% odds of the problem being the Defrost Timer looked pretty good, $30 including shipping versus a Sears tech phone estimate of $250-300. BINGO! Just follow the online installation instructions and don't forget to use the reset switch as described. Works like new! THANK YOU

Followed instruction vedeo from partselect. THANKS!!!!!

unplugged frig,removed bottom front cover and loosend 2 screws at bottom front left and slid defrost timer out from behind metal panel,unplugged the old and plugged in the new.frig works great.

Problem not consistent. OK for 2-3 weeks, then freeze coils. Mark and observe the defrost timers manual rotating adjuster. Timer would stop mid cycle. One revolution equals 8 hours of compressor run time followed by 30 minutes of defrost. Replacing timer took 5 minutes.

I followed the procedure online and found the thermostat was ok, it had continuity when cold, and the heater coil was also ok, it too had continuity, therefore the problem was a bad defrost timer. the refrigerator works great, thanks parts select!

Unplugged the frig. Removed temp control module from frig, 1 screw with nut driver. Activated defrost timer by rotating adjustment until 2 clicks are heard. Removed two timer mounting screws, unpluged timer, plugged in the new timer, mounted it to the control module with 2 mounting screws. Replaced control module with the 1 mounting screw. Closed door and plugged it up.

pulled down the thermostat cover and unpluged the timer control and replaced it with the new part. total time to repair was about 15 min. there was a vidio on how to replace the new part that just informed me that I did it right!!!!very easy site to find what you are looking for!!!!
