RT193MCD3 Frigidaire Refrigerator - Instructions

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.

real easy with the help of the video , made the difference

I snapped the brackets into the ends of the shelf bar, then inserted them into the holes in the door and pulled down each end until it snapped in place.

inserted shelf caps into rack strip then into openings and hit them with my fist (gently) till they 'seated' and locked

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.

open freezer door two screws just below unscrew slide piece to side unplug reinstall very simple.

Previously I glued them on with epoxy and Taped them. Often redoing. So I needed to clean the surface with goo gone. And to clean out the slots I used a utility knife. I had a small bump on the new end cap so I removed it with the utility knife. Simply put the end caps on the rail on each end. Then put the hooks in the slots and slide downward until it is secure. I should have thought of parts before! When the rail broke off I had cherries in a jar on that shelf. It crashed to the floor. I had a sticky mess every where.

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.

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

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

The repair was very easy. I had to squeeze the ends of the door shelf in a bit with pliers since the shape of the new end caps was slightly smaller than the shelf bar. BUT - here is the most important part. I had gone to a parts replacement store where I was quoted the price of $18.00 EACH for the end caps. Yes, $18.00 each!! With PartSelect, I paid less than that for the 2 caps including shipping - $15.42 total. Thank you, PartSelect.

You just slide off the broken part and replace it with a new part. I had to make a slight adjustment to the end of the shelf rail to allow the new piece to properly mate with the old shelf rail.

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.

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.
