HMG2170-47E Admiral Refrigerator - Instructions

evaporator coils were frozen solid and air wasn't flowing across them

read all directions first, then consider which steps you'd like to take

in any case...
- check for blockages in the upper and lower air vents that allow air from freezer side to cool the fridge-side
- inspect that the fan in the freezer side is actually turning and not blocked


- if no blockages and air is flowing between the sides...

- unplug the unit
- remove all goods from freezer and fridge
- remove freezer side racks
- remove rear panel on freezer side using philips screwdriver (note that the ice-cube tray motor housing must be freed by removing its screws. it can be pull out a bit to get to a single screw holding the top of the rear panel in place)
- allow the evaporator coils to evaporate all ice off, checking the drain pan under the fridge frequently - accelerate the process using a hair dryer or paint stripper (heat gun)
- disconnect the white wires from the connection block located about 2/3 of the way up the rear wall and check resistance using an ohmeter (see specs on back of fridge on circuit diagram)
- if you get a very high resistance reading, the heater element is likely broken. if so...
-- remove the 2 metal shields located horizontally across the evaporator coils (behind them are the two series-connected defrost heater elements)
-- visually inspect the elements - if they are discolored green or black, remove and inspect more closely (most likely they are blown, just like a light-bulb filament that shows black on the glass)
-- if you see nothing, remove them anyway (since high reading) and check connectors
-- replace them (likely only $30 to $75, depending on type)

- if coils seem ok, or if not suspect, check the defrost thermostat WHILE IT IS STILL IN A WORKING/COLD FREEZER.
- get the defrost thermostat into a coil chamber (other freezer or bucket of ice?) and check resistance using an ohmeter. It must be WELL-BELOW 40F to test it. When it is truly immersed in cold (as it would be in a working freezer), test the resistance. it should be 0-ohms when <<40F and some much higher resistance (>200KOhms) when > 40F.
- if not, replace it

-lastly, if neither the defrost heater elements are bad nor the defrost thermostat is bad, open up the defrost timer
-- the defrost timer is located in the fridge side, likely with the fridge thermostat knobs/controller
-- it is a 5-pin part that cannot be repaired. If all else is checked, most likely the defrost element is never coming on because the timer is not turning it on

it went good

remove all tray,remove back panel,cut out out old heater adn replace with new heatger,refitted back panel and alll tray.

Removed old water valve on bottom right back side of fridge installed new one which actually took less work

Turned refrigerator and freezer controls to off, removed icemaker bin, unplugged icemaker plug and removed two screws holding icemaker in place and removed icemaker. removed screws holding auger motor and freezer compartment light plate, unplugged and set aside. Remover screws holding freezer coil cover in place and removed cover. Allowed coils to defrost completely and then removed screws that hold the two defrost heater coil mounting plates in place, unplugged the two wires that connect the defrost heater coils to the connector block that is located above the freezer coil. Remove the entire defrost heater by working the connecting wires out from along side the freezer coil. Remove the clips that hold the old defrost heater elements to the mounting plates. Install new heating elements into the two mounting plates with the clips. Reinstall the two mounting plates to brackets on freezer coil and reinstall connecting wiring up to connector block and reconnect them. Reinstall freezer coil cover, icemaker auger motor and freezer compartment light plate, and icemaker and bin to complete job. Due to the confined space in the freezer compartment, reinstalling the freezer coil cover and light plate was difficult as I could only use one arm at a time resulting in many dropped screws.

Replaced the valve and cleaned all the coils at the same time. The ice maker is spewing out ice. Wife is happy again.

Ordered new single outlet water valve, received in less than two days. Removed old one, and the repair pretty much feel in place. Instructions were there as a backup. ........ Just curious if the connection from the water source to the valve outlet connection could b a quick connect just the like the water line going directly to the ice maker. Gregg in PA.

I removed all covers then removed screws from element and disconnected wires and removed it.
when installing the new heater I payed close attention to the routing of thw wires to insure that the terminals were connected properly. I then replaced all covers and turned the frig on and in a couple of hour it was working great again

Turn off water, removed two mounting screws, unplugged solenoid, removed incoming water connection and plastic pipe to ice maker. Installed new valve, connected water lines, reconnected plug, remounted with screws. Turned water back on, over rode power to ice maker and checked for leaks. Total time about 5 minutes. Very easy repair.

Very simple repair. Ice maker was operating, but not receiving water. Once new valve was in place it works like new.

Unplug the Frig and left the freezer side total defrost. Mine was so frozen up, it took about 6 hours with the door open. I had a towel in the botton to catch all the water and ice that fell.

Removed all the shelving units. There are 3 screws that hold the ice maker in place. Loosen the 2 screws above the ice maker about 3 or so turns. Then remove the screw under the ice maker completely. Then lift the ice maker off of the 2 screws that you just loosened. Then with a small flat blade screwdriver, push the plastic clip that holds the connector of wires that plug into the ice maker.

Then remove the screws that hold the back plastic cover that conseals the coil.

Now you should see the coils. There is one heater unit in the middle and one at the botton. There is a screw on each side of the heater unit that you need to take out. They are screwed into a metal bracket that is part of the coil system. Once the screws are removed, you simply remove the heater units. They are plugged in at the top of the coil system on a circuit board. Unplug them from there, (one of the spades connector was slightly bigger then the other, so I new where to plug them back in). Fish all the wire and heater untis out and you are ready to re-oinstall the new units.

Getting the wires back up through the coils was tricky, but I was able to do it.

The hardest thing was working inside the freezer unit. It is not very wide and was sometimes hard to get both hand inside to work.

The hardest part was taking out original light bulb because screws on shield where hard to unscrew after all this years . The old bulb vent out leaving neck in socket. It took narrow electrical pliers to get neck out .The generic appliance bulb did not fit and had aluminum neck ,not recommended for brass sockets in ovens.Putting new light bulb in was not the problem.

The old water valve leak required me to purchase this new complete part. After shutting off the water supply, disconnect the supply line, take out the old water valve by disconnecting the "plug" from the refrigerator, and disconnect the plastic water line going into the ice maker. Then just reconnect the new water valve by plugging it into the 2 pronged receptacle, note to be sure to write down which wire goes into which input when disconnecting the old valve. Then hand tighten the plastic tube into the valve. Next attach your water supply line into the new water valve, tighten this supply line as you would any plumbing supply line with a couple of adjustable wrenches and some teflon tape at the connection. I would also recommend at this point, if the compression fitting on your supply line was like mine a bit old, to spend a couple bucks on a new fitting and put that on the supply line, since you don't want to worry about it being a good seal at the supply line point, once the repair is done. After checking for "no leaks" reattach everything to the rear of the refrigerator (make a note of the attachment before taking out the old valve) and see if your ice maker starts to make some ice. You will hear the valve feeding the water to the icemaker if all is properly setup.

The first issue was to determine if the problem was with the ice maker or the water dispenser / pump. I chose to try to repair the dispenser first since there air bubbles in the plastic line. Also, the ice maker seems to have been working. There just wasn't enough water so the ice cubes were hollow.

I unplugged the power cord, , removed the cardboard backing and two bolts that secured the pump to the refrigerator. I vacumned the area so I could see around. I pulled the valve out and disconnected it from the internal power source. I disconnected the copper water intake and the plastic tubbing to the ice maker. I used a pipe cutter to take the old flanged area off. A new flange was included in the package. I used that and reconnected the copper intake and the plastic tubbing. I replaced the power source and secured the valve to the refrigerator makeing sure the plastic tubbing wasn't twisted. When I plugged the refrigator back up, the ice maker started working within five minutes.

Turned off water supply and electricity. Removed old valve by removing two 1/4 in nut screws and water supply line and the ice maker suppy line. Disconnected the electrical line.Reattached water supply line,the icemaker supply line and the electrical connector. Put valve back into refrigerator and attached the two 1/4 in nut screw. Turned on water supply and electricity. Bled water thru system and now have plenty of ice.
