It's been brought back to life.

 

Part of the original haul of vintage appliances from Newport, R.I.. It's back home. After a stay in Beltsville, MD, Jeff_adelphi replaced the compressor, defrost timer, fan and numerous other components for their modern counterparts. It has been converted to R-134 refrigerant. It is running well and consumes less power. Kudos to Jeff for a job expertly done.

 

This is a General Electric Model TCF19DBC Serial # LB631067.

The refrigerator was installed and has been working well. I had to keep the cold control at 8 in order to keep a temperature of 36F. Today I went to grab a can of seltzer and noticed it was not as cold as usual. I checked the thermometer and sure enough it read 55F. 

 

The compressor is cycling normally. Perhaps it's the cold control, the fan in the refrigerator section or the defrost timer.

The fan is working well, a bit noisy but it spins freely. I will add a few drops of Turbine oil since I'm here.

It appears to be the defrost timer. I manually turned it to defrost and was met with a loud "crack" as ice started to melt.

 

I will order a replacement.

The original defrost timer for this General Electric is MOD. WR9X330. However, it was replaced with a Paragon MOD. A-772-00. Other defrost timers for this refrigerator are Gemline MOD. WG-840-1 DT 105 (Paragon clone) and Uni-line 8-805.

 

There is an original, NOS WR9x330 on ebay, but a bit pricey at $80 plus shipping. I ordered a NOS Paragon MOD. A-772-00.

Installed a few days ago and the issue continued. The timer was not advancing. Went back and discovered the black wire (hot) was just hanging by a few threads to the terminal. I switched it out, advanced the timer to defrost and waited.

Still not advancing.

 

 

I should have done this before, I'm going back in with a multimeter to see if there is any current being supplied. Perhaps the wire slipped out of the terminal again. Or perhaps its the neutral.

 

[Ultramatic]

 

 

I checked the contacts, they are fine. Power is being supplied to the defrost timer. The timer does advance to end the defrost cycle and start the cooling cycle, however it seems to get stuck there, just right after. I hear/feel the timer running. I was manually advancing the timer twice every 24 hours to keep the refrigerator running. However, last night I found literally sheets of ice behind the coils. So it wasn't totally defrosting when I manually advanced it. So I put it in defrost mode 3 times. That did the trick. The ice behind the coils melted.

 

Nevertheless, I am pretty certain the timer is defective. If it does not advance this time, I will reinstall the original. Perhaps it was good to begin with but was running intermittently due to the very loose hot wire.

It's certainly not unheard of to get a new/defective timer.

 

[Ultramatic]

 

 

I changed the defroster timer back to the original. It too is working. And I also noticed I haven't seen the evaporator fan working, and sure enough, you can barely turn it with your finger. Seems like the bearing are bad. As I mentioned earlier a great deal of ice forms back there,  I defrosted all the visible ice and removed all the screws, and the black plastic cover won't budge. Perhaps there is still more ice behind it.

I'd like to find one of these...

I have a feeling that the fan motor housing (the black part) is sealed with permagum, which is holding it. You may need to warm everything up a little bit and apply moderate, constant pressure to get it out.

 

[Ultramatic]

 

 

Permagum? Wow, they certainly didn't make it easy to remove the evaporator fan. I'll be removing the aluminum cover to get a better grip. This is going to be a delicate task. Thanks David.

 

[turbokinetic]

Originally the permagum was supposed to stay PERMAnently GUMmy and never turn hard. But over decades it hardens up. Heating gently with a hairdryer etc. can help soften it.

But yeah it has to be done carefully so as not to break the fan motor holder.

 

[Ultramatic]

 

 

So I struggled to remove the evaporator fan housing. As David suggested I used heat to soften the Permagum. Little by little it separated. But it kept hanging on tight. Then I noticed the center of the housing, where the shaft is was exceptionally cold. So I began to suspect there was ice build-up behind the fan, in fact inside the fan itself. After a few more passes using a blow dryer, it finally came free. Low and behold, the interior of the entire housing was a block of ice. Not only that, there was over an inch of ice running the entire width of the freezer. It was so thick, it took me 20 minutes just to begin the see the wires for the fan. No Permagum just a surprising amount of ice. Now, since I applied so much heat to the fan housing the shaft is spinning freely. I will check it for continuity to see if it's OK.

 

Ice



 

More ice



 

And yet more ice

I'm turning off the GE for at least 24 hours so all that ice can finally melt.

 

Fan motor tested at 83 ohms. Which means it's good.

Quite a lot of water got in there to freeze it up like that! There is a chance the electrical connectors for the fan motor are damaged from the ice / water being in them. You might want to verify that they are still capable of making good contact.

Also see if there is any way defrost water can flow behind the fan mount, become trapped, and fill it up like this again. Somehow that water got in there and froze up.
