Dear Group,
I recently purchased a D-2-A16 machine on Craigslist, and it arrived yesterday. I followed the video advice here and checked the ohm reading across the heater unit with the machine plugged in and control off before i tried to fire-up the machine which had been sitting in a basement unused for many years. I got no reading across the control terminals, so I guess the original is shorted. I did want to see if the machine would even run, so I turned it on after some cleaning, and on the second attempt it started! It was pretty loud at first but sounded okay, and I figured this was from the cold oil. I ran the machine about 20 minutes and it quieted down noticeably (but still not really quiet) and the entire freezer was already quite cold.
I read the posts about replacement heaters, but I wonder if there is any advice about which is the best for this machine? The previous owner also seems to have lost the power cord, so I wonder what fitting best adapts to that plug? Finally, it needs a new door gasket. Any advice about the best type for this unit? I can see it has a pop-in style gasket, so I am guessing a replacement will have to be glued on.
Finally, should I keep running the machine without the heater or will I be doing damage?
Thanks to all for being so helpful on this form. I am so thankful that this almost 90-year-old machine got saved and that it still works!
Rex

You got lucky. I would use an 18-20 watt heater. I seem to recall 12mm being the diameter. I’ve encountered machines where 1/2” was too big. 2.5 inches long.
The gasket many use is a D type self stick type from McMaster-Carr. It’s black and reasonably priced.

Dear Travis,
Thanks for this help. Where does one acquire the correct heater? I did see the gasket reference under the "suppliers" tab. I appreciate your help!

Rex,
I believe there’s a thread under suppliers. Look around. It’s all been discussed again and again. I don’t recall who I ordered from.

Dear Travis,
Thank you for writing. I know there are a number of thread about these heaters, but it is still difficult to determine which one and from whom is appropriate for the D machines. The oldest thread gave a part number from a defunct supplier, but after that there was no sure course of action. I really don't want to pull the original out until I have a replacement, but I remain unsure which one is best for the D machines.
Have a good weekend! Rex

All of the suppliers can make a heater. It’s the same type. The only difference is that some suppliers have been great to deal with and others not as much. The problem is that most are inconsistent. I use 12mm to avoid some manufacturing differences in the heater tube.
I’ve used Nordic more than once, while others have sworn they’re difficult. I’m not opposed to trying a new supplier. You’ll also find some disagreement about wattage. I’ve found DR1s and DR2s with old working heaters pulling 15 watts. The bigger DR3s had 18 I believe.
Nordic said the wattage is approximate. I have some 15watts pulling 17. It doesn’t matter really. I would stay between 15-20 on a 1 or 2 size and 20-30 on a 3.

Fabulous help, Travis, thanks! I'll let you all know what transpires with this machine. Now I have something to go on when I talk to these suppliers!
Best,
Rex

Hello and welcome to the forum always interested in seeing new people join ! I would not recommend running with out a heater , for reasons I won’t go into it’s not a good idea . I bought mine from Nordic sencers (may be different spelling) from Canada . But they are listed in the suppler section ray has a diagram of the proper size
and length /diameter if it’s not there maybe he we’ll post it . As far as wattage for a heater 12 to 15 watts seems to be the original heater . We have found out they preform
better with a little higher wattage heater like 20 watts. (Maybe other members we’ll give there opinions)

Thanks so much Elec! I appreciate the advice and help. I am not going to run the machine again until I have a heater. I cannot find anything about how long the heater needs to be, but the 12mm diameter and 20 watts seem to be the consensus for a D2 machine. Thanks again! Rex

Can anyone tell me what a D-2-A16 is?

I also have a D-2-A16 that I am presently working on. I have had it running in my dusty shop for about 2 years. So I decided to build an office to put all my toys in to try to keep them clean and dust free. So I got the office built and trimmed out, cleaned off the GE and blew out the dust. Plugged it in and promptly the overload protection wire got red and fryed. So I decided to check all the wiring and heater. First in pulling the heater, I noticed a loose wire while I was pulling it out, so obviously that needs replaced.(I don't know if I broke it while pulling or if it was already loose) I also tested the winding's, and I will list them.
Red to ground 10.2
White to ground 8.9
Black to ground 4.5
Red to Black 14.1
Black to White 4.7
White to Red 18.0
Is the overload wire available, or do you just remake your own? I have contacted several vendors about heaters. So far 3 no response, 1 for $129 and 1 for $89. Too much$.
Can anyone tell me if the readings on the wiring looks correct. It was measured at the end of the wire, not at the posts of the motor, if that makes a difference.

Jan,
You’re unit appears very grounded. The overload burned because of this. I suspect the damage is internal, but you can insulate the motor leads and hope to get better readings.
I have other units that are also failed. In the future when you find a unit that’s more viable a heater will cost you between $25 and $40. There are numerous threads here about heater suppliers.

I checked one of my spare heaters I bought from Nordic Sensors . They are located in Canada and you have to fill out some paperwork to get them . The barrel is 2and 9/16 long
the diameter is just under 1/2 inch . The leads are 15 inches long , you can get them different lengths that’s up to you. But you want a heat resistant wiring.
Some others have used a company in the states with good luck. So I think I’d try them , there listed in the suppler section.
