MRT18BSCW7 Frigidaire Refrigerator - Instructions

removed screws with from the back panel of the freezer; located defrost thermostat attached to coil with a metal clip; unplugged thermostat and replaced with the new one. Put every thing back together and it works perfectly.

Removed old gasket and installed new one

Parts Select is an excellent source for help and parts identification. I highly recomend them.
My first option was to replace the defrost timer.
After still getting ice and frost buildup in freezer I decided to replace the defrost thermostat.
Remove all shelves. Losen icemaker if applicable. Remove light cover and bulb. Remove all screws securing rear vertical cover. Carefully move back panel, disconnect icemaker and bulb assembly. carefully remove styrofoam cover at upper left and remove defrost thermostat. I tested the thermostat and found it was defective. It would not close circuit after being placed in a working freezer. Reverse procedure to replace thermostat.
This solved the problem

just like the video showed...it was excellent!!!

took 4 screws out of the discharge vent on top of the refrigerator section and unpluged the wiring harness and put the section on the counter and unscrewed the timer and put the new one in and reinstalled the assembly and plugged the Jack and put the 4 screws back in, and rotated the timer and put it on defrost removed the back and check the heaters and drain .

I original tried to repair the motor but was not able to. I remove the screws on the back plate and removed the the back plate. Removed the shroud for the motor and screws, unplug the power connection and removed the fan motor. Installed the new fan motor and reassembled everything. The refrigerator is working great.

The old drain pan had a 1 ½” tall bushing attached to the center of the pan. The new pan did not have this bushing which was great. I had to cut about 1 inch off the bushing to remove the old pan. Also after cutting the bushing I had to screw the bushing off after cutting the old pan from the bushing. I installed new pan onto the ½” of threads that was left on the top of the compressor. Checked repair two days later all was great.

I took the freezer door off took center hinge out , took frig door off , unscrewed inside panel took off old gasket , put the new one on , put inside panel back on , (be sure the flange on the gasket stay's in the groove when you screw it back together) replace doors and anything else that needs replaced ! check the seal !

I did not remove the door from the unit! put the seals out in the sun for a couple of hours to soften and straighten. open door, loosen screws around inner liner(they are under the seal lip) DO NOT REMOVE SCREWS!. gently pull old seal out from under the edge of the liner. starting at one corner, gently ease the retaining lip under the retaining edge of the liner. after completing this, tighten screws from the middle of the door to the outer edge starting with the top of the door. do the sides next, then the bottom. next, apply silicone sealant to the corners as per the instructions supplied with the seals. apply Petro-Gel, close the door, YOU ARE DONE!

The instructions given to me by part Select were very good.I replaced the Timer- checked the heater with oham meter it was good- checked the door weather striping it was good and replaced the thermostat with new .So at this point I may need to call a professional unless some one has another solution.

Ordered the new part-Unplugged the refrigerator - took off the cover over the defective timer - put in the new part put the cover back on - plugged the refrigerator back in - so far, so good!~

Watched video on Part Select which shows you how to replace the thermostat with several good pointers. Very easily done and now the freezer works great.

I'm not knowledgeable on Refrigerators or A/Cs, so when our Frigidaire stop working,I told my wife that there was nothing I could do to fix it. We had friends that had a spare in their garage so we offered them $500.The only thing wrong it was the ice maker. When looking at the manual and parts I came across this site and didn't realize that the air went through the freezer first. After putting my model number in,it showed the common problems with that fridge, then I watched the videos and realized how simple it really was.I Just had to remove the freezer panel in the back to replace the thermostat and the defroster was easily at the bottom front to the left corner, it cost me about $46 and about 30 minutes of my time. I'm a handyman and I do almost all my repair work and almost gave this fridge away. I can't thank this website enough. Yes, we spent $500 on another fridge but, it was one that my wife was wanting anyway. Thanks again

Emptied freezer, removed fan motor cover (2 screws), removed fan and motor (2 screws), removed old motor from bracket and reassembled with new motor, transferred fan blade from old motor to new), re-installed new fan/motor (2 screws) and reinstalled cover...

Removed the lower trim panel from front of fridg. and loosened two screws enough to turn it about 1/4 inch so the screw heads were in the larger holes. Pulled it out disconnected the wire connector and transfered the heat shield and screws to the new clock, connected the wire connector and aligned the screws. tightened them and job done. Has worked like new sense. Thanks Roger
