MRT18G Frigidaire Refrigerator - Instructions

First, unplug the refrigerator since you're working with live wires.

Remove the 4 Philips sheet metal screws holding the plastic housing that holds the temperature control to the top of the refrigerator compartment. Pull the housing down then out since there is a tube on the housing where the water flows out the back of the re ... Read more frigerator during the defrost cycle.

Remove the 2 Philips screws holding the defrost timer on the plastic housing. Pull the connectors off the old timer and attach them in exactly the same positions on the new defrost timer.

Attach the new defrost timer to the plastic housing with the 2 screws.

Reinstall the plastic housing, making sure the water tube is inserted into the back of the refrigerator wall.

Plug the refrigerator back in and you're done.

I ordered a defrost timer and defrost thermostat from partselect.com. Parts arrived in 2 days (earlier than expected). Unplugged appliance, removed bottom cover, unscrewed 2 screws holding timer in place, unplugged timer and replaced with new part. Fastened back into place. Next removed back cover of freezer (5 screws using nut driver ... Read more ). Disconnected old thermostat and removed. Wires already had connectors installed. cut off the connectors with some wire left on and reconnected them to the new thermostat with the included blue wire crimps. Tried to use the shrink tube to insulate but couldn't get it snug enough. Just used electrical tape instead. Reinstalled thermostat. Reassembled cover. Plugged in and fridge and freezer are working fine again. Thanks partselect.com.

Removed the temperature control dial,took out the 3 screws that hold the cover for the thermostat and defrost timer, disconnected both the defrost timer and thermostat and replaced with new items. The refrigerator temperature has now been staple for one week.

remove all freezer items and remove back panel covering the coils - about 8-10 nuts using a nut driver. The coils in my refridgerator were covered with a heavy frost - thermostat was also frozen over. Manually turn the defrost timer so the fan turns off to observe if the heating element is working (defrost timer is on the bottom front o ... Read more f the refrigerator on the left side). My heating element did work so I decided to replace the thermostat and defrost timer. Unplug the refrigerator. Disconnect 2 wires connecting the thermostat and unhook. Replacing with new thermostat - red and white wires that have male/female connectors and hook onto coil as before. Note that two parts with similar names were offered by PartsSelect and you really couldn't tell which was the right one - I got both but returning the unused one was very easy but cost a couple of bucks in shipping. Next, take out two screws and the bracket that holds the defrost timer in place and unplug it. Plug in the new one and screw it back in. Reinstall the back panel - throw out all that stuff in the freezer that you've had in there for 10 years and turn it back on - very simple and it worked perfectly. Very good experience with returning parts - excellent customer service.

unplugged, removed old parts, replaced with new

This was a simple job. Raised the flap in the back that houses the compressor, removed the wire that holds the relay, pulled out the old relay and pushed the new one on. Replaced wire holder and that was it. Plugged it frig and freezer is at zero and lower compartment at 35. As easy as brushing your teeth!

The Roper part was no longer available and a substitute was not recommended. But because of the excellant descriptions and photos on Part Select I was able to find a Fridgedaire part that looked exactly like the one I needed to replace. I it fit perfectly... I am impressed and have bookmarked your site for later purchases.
The thermo ... Read more stat is located at the top of the refridgerator compartmennt under the freezer. Remove light bulb to access the screw at the back of the thermostat/defrost timer housing. Remove screw and slide the assembly to the back to release the 2 tabs holding the front. Remove the temperature control knob on the thermostat, remove the 3 wires connected to the thermostat noting where which wire goes for re-assembly. Using a philips #2 screwdriver, remove the 2 screws under the temperature control knob and remove the thermostat. Do not lose the screws, the new thermostat does not have mounting hardware. Piece of cake, Ice cream cake if you get the freezer working again.

I located the part that was the culprit as it had buzzed very much before quitting. This is an easy removal as the part is in a two prong jack and just needs to be carefully removed with the new part inserted back in the jack provided. The refrigerator works fine now, but the run capacitor will still buzz on start up of the compressor. I ... Read more do hope this is normal in this model? anyway it runs fine mow. Thank you.
