RT179HCD2 Frigidaire Refrigerator - Instructions

According to the information from the parts select website the thermostat and the defrost timer where ranked number 1&2 as likely to fail and cause the condition experienced. To replace the Defrost thermostat just remove the freezer bins and the lower panel covering the evaporator. Remove the old thermostat, measure the wire lengths and install the provided crimp splices. Note: the heat shrink tubing is WAY over-sized and will not shrink to the size needed. You will need another means of sealing the wire connection. Install the thermostat and replace the panel and shelves. The timer is real easy. On my model it is located under the freezer door under the kick panel on the front. Simply remove 2 Phillips head screws, unplug the old unit and install the new one. Be sure to cycle the thermostat past the defrost cycle on the timer (rotate until an audible click is heard once for the beginning of the cycle and one at the end) so that the unit will start up when power is reconnected. This resolved my problem and the unit is working great!

I needed to determine if the heating coil was ok. I bypassed the thermostat, rotated the defrost timer manually with a flat screwdriver until it clicked. The coil heated up and turned a glowing red. So the coil was ok. After looking at the wiring diagram located on the back, the only parts in line was the timer and the thermostat. So I ordered both, replaced them, and everything is working fine. I went online about noon on Thursday, placed the order. The shipping indicated 2-3 business days. To my surprise, they were delivered to my home on Friday, mid morning. Great service from Part Select.

with patience

The temperature was slowing rising in the refrigerator section of a side-by-side. As a precaution, I changed out the defrost timer and defrost thermostat. The parts were not expensive. I then tested the defrost heating element with a multimeter and found the actual culprit was a burned out heater coil. I ordered the part one day and it was delivered by FEDEX the next day. The three parts were much cheaper than a new refrigerator and took little time to install, thanks to the Parts Select website and the how-to-install videos. Now the fridge works great and we saved having to buy a new appliance.

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.

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.

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!!!!

Just followed the online instruction video .It was very easy.

Diagnosis: used wiring diagram attached to frig and determined cause could be wiring, heater element, thermostat or timer. After completely defrosting the frig (turned it off) I removed the rear cover in the freezer and looked for an obvious problem. None seen. Removed temperature select pod from the frig box and looked for obvious problems. None seen but defrost timer appeared poorly made. Repair: Since I had no practical way of checking the defrost cycle in operation, I checked probable failures on the Part Select website and saw defrost timer as most probable. I ordered the timer. Installed it. Waited a few days to make sure the frig went through a few defrost cycles then removed the freezer rear cover. There was no excessive frost buildup so I'm reasonably sure the repair was successful.

I went on partselect put in make and model number, a list showed the probable cause. I watched the how to video. When I received the part in short order I loosened 2 screws disconnected the wiring plug (sprayed it with contact cleaner) pluged it in, removed screws from old part put them in new one. Put timer back in its location and tightened the screws. Very eazy, works fine.

I pick up very fast at these kind of small jobs but because of my very busy schedule I decided to call (2 times) technicians about my problem but none of them had any idea. About my repair, I removed the grill at the bottom of the refrigerator, unscrew a small plate (located on the bottom left side) that's holding the defrost timer. I plug on the new part, screw back the plate with the defrost timer and that was it. Don't forget to turn clockwise with your finger the timer until you hear a "click" and then turn it slightly more to the right. There is also a video on U-tube.

I first thought the defroster heater broke - took the back wall of the freezer off and cooling fins were fine. Then took the defroster timer out and opened it up. The contacts were badly burnt so the compressor and fan ran during only part of the cooling cycle. Replacing the timer took less than 5 minutes - turn off the power, remove one screw to take out the control box, cut the ground wire (new timer housing is plastic and does not have a ground connection), remove two screws to unmount the timer, unplug the old timer, plug in the new timer, fasten with two screws, put the control unit in and fasten with one screw, turn power back on.
