RT177MCF0 Frigidaire Refrigerator - Instructions

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.

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

You guys at Partselect are the best!!! Went to your site, typed in my appliance symptoms, and received possible fixes. Ordered the suggested parts (under $50) on a Sunday night and got em Tuesday am. Installed the easiest one first and Voila!!!! Frig is working great. Thanks Bob S

Remove 4 screws that hold up overhead controls, this is also the part that holds the light. Unplug the timer and replace. Super simple and runs great now. After you plug it in it may take a few minutes to kick on the compressor but it will. Also I was pleased it was a factory Frigidare part. Price was right.

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

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.

After reading other posts, I decided to change the defrost thermostat, so I watched the videos, and did that. It got better, but the problem persisted, and the ice was still building up in the freezer section. So I decided that the problem was with the defrost heater. I ordered a new one, that was here under 24hs (using the Fedex ground). I replaced it, measured the old one and saw that it was not passing any current at all (so it was really burnt). Now the fridge is good as new, maintaining the proper temperatures both at Freezer and Fridge sections. Thank you Parts Select ! With $ 70 in parts I was able to get back my appliance working !!!

I am a 65 year old woman with no mechanical aptitude: I just unplugged the frig. And used a screw driver to pry of the plastic socket from its outside edge. . Then you just unplug two tiny contact plugs that appear when you pull out the socket and replug in those two the same way on the new part. Pop the socket back into the hole . . . . And screw in the new bulb. I knew I needed the socket part cause when the bulb burned out , a new bulb still did not work. . . If I can do it, anyone can!

Removed the timer, installed the new one. Great service from part select

Instructions from partselect were very clear and probable cause made it easy to narrow things down. I have the manual for the refrigerator that shows the location of the defrost timer. Very surprised that it turned out to be a cheap and easy fix.

The repair was straightfoward. The evaporator motor I received from partselect was a different model with different wiring configurations. I cut the wires from the new motor per the instructions I received with the new motor and I did the same with the wires that connect to the fridge. Once I matched the wires and secured them with electrical caps I began to put the evaporator motor to the base and started screwing the screws the way I took them off. Once I connected the wire harness to the back of the freezer and turned it on I noticed a big difference in air flow. I was surprised at how easy it was to fix my refrigirator problem. It's been a few weeks now and the fridge is cold and working like it should. Don't be afraid of this task. it's very easy and will save you a ton of money. Thanks partselect.

Simply replaced the defrost timer located inside the frig just behind the temp dial. Very easy job. Removed the 3 screws holding the temp sw and light assembly. Removed the defrost timer w/ 2 screws and put i all back together. 15 mins at most. Suggest you watch the install video for pointers.

First I replaced the defrost thermostat, then I realized that the evaporator fan would stop turning periodically. I could restart it by spinning the fan with my finger. The fan is behind a cover in the back of the freezer. If you remove the cover and check on the fan when you hear the condenser fan in the back running. (They seem to run at the same time.) It was easy to replace the fan and the new one is more powerful than the original. The refrigerator runs fine now. Thank you for this great site. Saved me a lot of $$.

Followed the instruction video. Removed the old one. Attached the fan blade, ground wire and connected power plug. Reinstalled with 2 screws. Works great.

Unplug the refrigerator unit from wall. I removed freezer rack, plastic light cover, the ice rack shelf on the right side, then removed the plastic back cover panel, (4) retaining screws, gently tilting the panel toward me, unplug the wiring harness by depressing the clips on the side of the plug, removed panel from unit, set aside. If the unit was froze up, so I defrosted the cooling coils carefully with a common hair dryer until it was thawed. Be careful not to touch or bend the coils , since they are very fragile and SHARP! I located the old thermostat unit attached to a straight length of coolant line. The new unit looked like the old one, so it was easy to locate. I cut the two wires of the old unit close to the round base to make sure I would have enough wire to reconnect. Since my new unit did not indicate a polarity(Neg or Pos), I just wired each wire I cut to one of the new unit. I used the shrink tubing provided and heated the shrink till it was fully melted. I double ck'd to see if the wires were basically waterproof and a good connect. Also, before I replaced the rear panel, I made sure that both wires I had spliced had a drip loop to it so water would not drip down into the newly spliced union. Also made sure the wires will not interfere with the colling fan on the back of the rear panel. Reverse the procedure in reassembling. Plug in unit, and wait and listen for the unit coming back on..I kept a regular thermometer in the upper and lower compartments. Allow 24 hrs. for the unit to return to normal operation. It may defrost several times till the whole operation is back in sync.
