MRS20H Refrigerator - Instructions

Fridge is a side by side. The freezer is pretty narrow for a guy with wide shoulders.

Pulled plug.

Had to remove bottom drawers then used nut driver to remove screws closest to back wall in drawer runners. Once the back screws were removed the runners could be swung up or down out of way so back cover could be re ... Read more moved.

Once back cover was removed thermostat was located attached to top pipe going into coil using a spring clamp.

Cut the wires just outside the crimp connectors going into thermostat. Released the spring clamp buy squeezing botton together.

Removed old badly corroded thermostat.

I wish I had attached the crimp connectors to the new thermostat wires before mounting it. Reaching way in the back, while turning shoulders verticly and trying to get the wire connectors set from both sides was awkward and uncomfortable...The biggest PIA of the whole task.

Once connected I let the fridge (thermostat) cool for 10 min. Turned the dial defrost timer to get it into defrost mode. Stupidly touched the heating element to see if it was getting warm...it was very hot.

Coils steamed...every looked like it was working. Unplugged, put back cover back on and retattached drawer mounts.

Plugged back in and everying is working great!

My freezer would freeze up and not allow cold air to refrigerator side. First I took off bottom face plate, located the timer on left side bottom, removed the two screws and unpluged the timer.

First - I asked a person familiar in ref/freezer repair for assistance. This was the hardest issue - trying to find someone to offer "free" advise. He stated that when this problem occurs it is usually one of two things: 1) The defrost timer (underneath Refrigerator - Attached w/2 screws and plug-n connector) not functioning or 2) The de ... Read more frost sensor (clipped-on to the coolant line (2-press-on wires) above the main coolant coil in in rear of freezer section behind panel secured w/5 1/4" hex-head screws) not properly sensing need for defrosting. The Tech. also stated that the defrost/heat coil, which surrounds the large coolant coil in the back of the freezer hardly ever goes bad unless it is the glass/clear type coil which often crack. (Mine was the black filament type element like found in an electric oven). I check the element with an ohm meter - 27 ohms of resistance which indicated it was okay). I replaced both defrost timer & defrost sensor at the same time and that fixed the problem. Parts ordered were an exact match to originals (dispite model number changes/upgrades) and everything went very well. NOTE: It is good to have the part numbers off of each original item and know what they are called before placing your order. All fixed for less than $50.00. A service call alone would be more than this. Took about 2 hours to do, due to having to defost the iced-up freezer coil w/a hair blower. Don't use sharp objects to chip away ice, let the blower do the work - Patience and a couple of towels to absorb water is important here. Hope this helps the other do-it-yourselfers.

UNPLUG REFRIGERATOR. Carefully remove relay from the side of the compressor. You shouldn't need a tool to do this, if it is hard you can gently pry the edge with a flat head screw driver just to loosen. Unplug white and red wires from relay, noting that the white wire goes in the hole with a #2 stamped beside it. Shake old relay, if it r ...

My freezer was frozen but my refrigerated side was not cooling, the temp was actually around 60-degrees.

I'm too young to die so I unpluged the refriderator first. The cold control is mounted in a plastic housing at the top of the freezer compartment that is held in place by two screws on the back side.

Plugged in and fridge and freezer are working fine again. Thanks partselect.com.

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.

Used exploded parts view to locate part. Removed old part and replaced with new defrost timer. Piece of cake.
