Montgomery Wards Frostless 18 HMG1879-4 warm refrigerator

12 posts in this topic

I checked out some of the forum posts but nothing quite like this. I'm guessing it's a typical refrigerator problem for you all so I appreciate any help on this. My refer is about 25+ years old so I don't expect miracles. However it is the basement beer refrigerator and while the freezer seems to freeze...the temp in the refrigerator has gone to 50º. The first time it did, I unplugged for a day and then plugged back in and it was okay for about 3 weeks. Visible symptoms are drain hose in back is icing up, inside back panel of freezer is getting a layer of ice, and after a couple of weeks the fan/compressor/whatever that sound is that comes out of the freezer and is normally quiet...is now like a hackety-hackety-hackety LOUD sound when you open the door. Oh, and you can't adjust the temp knob inside the freezer on the back panel, as it is stuck like it's frozen. I only feel a slight hint of a whisper of a breeze coming out of the refrigerator column where presumably the cold air comes in from the freezer. I'm not that mechanical but I might have a male friend that I can instruct... if you can direct me to what the problem might be and where I could get the part. If it can't be fixed I guess it means I'll have to stop drinking beer. Ughhh...that doesn't sound right.

... drain hose in back is icing up, inside back panel of freezer is getting a layer of ice,

... the fan .. is now like a hackety-hackety-hackety LOUD sound when you open the door.

I can't find any info on that unit, but

it sounds like the Freezer Evaporator is not being Defrosted ... and the Evaporator Fan Blades are hitting the "frost'

Can you post pictures of the Freezer Evaporator Coils ?

Again...sorry I'm no repairman...but if you mean the coils behind the freezer panel...I haven't taken that off. Can you be specific as to where those are?

At this point, It's been unplugged for a day and a half and it's hopefully defrosted. But sadly since it's defrosted I won't be able to get a look at the coils to see if your thoughts are correct. Once it's plugged back in i can probably take off the panel and take a look. Was hoping to do that when it was down but I guess some diagnosis require the "what's going on at the time" so you can see the excess freezing, etc. I'll plug back in but may take some time to get to that point again. Meanwhile, i'll research the freezer evaporator.

since it's now completely defrosted,

the Fridge may cool fine for a few days or maybe a full week

The evaporator coils in this unit are under the freezer floor panel. The glass defrost heater may be bad. A common failure sooner or later on these.

Also clogged drain hole in the center of the freezer.

You have to remove the door,hinges,mullion panel to get the freeser floor panel out.

Be sure to use a sponge to remove all water from the fan motor comparment.

The defrost thermostat is on the left rear corner or front center behind the toe kick plate.

Another potentially failed part.

These old Montgomery Wards HMG models are usually made by Admiral and to access the evaporator coils is not the easiest of jobs.

You have to remove the doors and then remove the center divider strip between the freezer and refrigerator, (the mullion strip which has a heater on it, should have plugs to unplug it).

Once that divider strip is removed you have to pry the plastic floor out at each side and slide the complete freezer floor out.

There will then be a syrofoam sheet with a thin aluminum shield on the bottom of it. If you haven't let it thaw out real good you can very easily break this cover, so be careful when removing it.

The defrost heater should be a glass tube heater running down the center of the evaporator coils covered by a metal shield. When the defrost goes out in these it will break the glass tube lots of times because of all the ice buildup around the glass tube.

I think you mean the defrost timer is behind the toe kick plate, NOT the defrost thermostat.
