I am looking for any information I can use to replace this compressor,
I have included a picture of the label on the compressor for reference.

It is installed in a top-loader style chest freezer,
additional information provide below to help as well.

Freezer Sticker:
Rheem Manufacturing Company
Refrigeration Products Division
Williston, S.C.
Listed Household Freezer 234A
Model No. C 15 AAJWN (MAYBE !)
Serial No. 537585 (MAYBE !)
(Numbers stamped, no ink used...)
R-12 @ 7.75-Oz Charge
235 High Side
140 Low Side
(NOTE: Sticker# C-45755)

Compressor Sticker:
Comapny Logo: N
MK7 (Model?)
R-12 2.6-FLA 24-LRA
Single Phase
Thermally Protected
2061 (Date Code Maybe ?)

NOTE:
Above entries marked "MAYBE" are only my
best guesses with a jewelers eye loupe.
The frezzer label was embossed without ink,
and was not done very well, so was iffy...



I am (now...) a retired marine electronic's technician,
but I have installed my share of land and mobile AC's.

I have never seen both of the lines from the condensor,
and also from the evaporator go through the compressor.

Why does this compressor have four ports, not two please ?
(Five, if you include the vac/fill/pinch service port stub...)



I would need the capacity for this compressor as a minimum of course,
but a recommendation for a 12/24/48-VDC compressor make & model,
or full inverter-style replacement recommendation if possible please.

This is a back-burner project, not a fast repair, so I have time for research.

Collected Info So Far:
1 - R12 based, capilary metered system
2 - 2.6-Amp @ 115-VAC rated usage
3 - 24-Amp @ 115-VAC locked rotor
4 - "2061" may be a date code
5 - Company logo is an "N", lol...



Thank you all in advance for any information on this compressor.

I contacted Rhhem, and received confirmation Magic Chef may be
the only personal that may still have information on this appliance,
I haven't contacted them yet though, thought I'd tap your experience.

here is some of the information I've found while researching this appliance,
and the specific manufacturing location this exact unit was manufactured in:



In May 1966, Chill Chest, a current division of Revco,
constructed and began operating a refrigerator/freezer
manufacturing plant at the current location of the current
Dixie-Narco plant on County Road 65 (Dixie-Narco Boulevard).

Several acquisitions involving the manufacturing plant
took place during the period from years 1968 to 1981.

In 1968 Guerdon Industries acquired Revco.

In 1969, City Investing Company acquired
Revco, and Guerdon Industries.

In 1979, Revco became the Refrigeration Products
Division of the Rheem Manufacturing Company.

In 1981 the Williston plant site was acquired by Magic Chef,
of which Admiral Home Appliances was a division thereof.

In 1986, Maytag Corporation acquired Magic Chef,
and all of its companies, including Dixie-Narco.

In 1989, Dixie-Narco moved production of vending machines
from Ranson, West Virginia, to the Admiral Home Appliances
freezer factory in Williston, South Carolina.

In September 1989, Dixie-Narco began manufacturing
soft drink vending machines at the plant.

Between approximately 1971 and 1989,
the facility operated a fork lift repair shop and paint booth.

These structures were located on the north central side of the plant.

Between 1971 and the early 1990s, the plant underwent
a series of renovations and expansions.

In the early 1990s, the fork lift repair shop
and paint building were dismantled.

The plant was expanded to the north and an access road
for to the rear parking lot was installed over the former
locations of the paint booth and forklift repair shop.

From review of historical documents, and discussion with
plant personnel, the pre-1982 manufacturing process at this plant
consisted of forming and stamping of steel into freezers.

The processes included conversion coating and spray- booth painting.

The conversion coating process used an alkali solution to clean the metal,
a zinc-phosphate spray to prepare the surface next,
and a chromic acid cleaner to enhance paint retention.

It was reported that the zinc-phosphate spray also contained nickel.

It was also reported that the spray booths and paint spray nozzles
were cleaned with solvents including toluene, xylene,
methyl ethyl ketone, and diethylene glycol monobutyl ether.

Rheem Manufacturing Company conducted a removal action
in January and February of 2005 to remove the Imhoff system.

Necchi would be my guess.. 7 would be the cc.no longer in business so use a danfoss.

if there are two parallel stubs near the bottom of the pot then they are an oil cooling loop.

Necchi would be my guess

N (Logo) = "Necchi", gotcha



7 would be the cc

M7K = 7 Cubic Centimeters (Volume) / Minute ?



no longer in business

Heheh, yeah that figures...



so use a danfoss.

Was my thinking,
but the variable speed inverter market has exploded,
everyone from Hitachi to matsu****a have nice sets,
and they easily take low voltage DC and houshold AC.



if there are two parallel stubs near the bottom of the pot then they are an oil cooling loop.

Thats the ticket, thanks, they are at the absolute bottom of the unit, and side-by-side...

This makes sense, the condensor loop, and it is just that (not a finned array),
is tubing ran around the whole chest, over and over, using the outer (metal) skin
as It's radiator of the excess thermals harvested during the refrigeration cycle.

An oil cooler loop for longevity of the compressor makes some sense now. :)

Thanks R. Bartlett,
Paul

Heheh,
Mat-su-shi-ta, the company, apparantly,
looks like S H I T to the explicative filter,
who says computers don't run the world...

Found it, Richard is right, it is a necchi.

Thank you also Chemi-Cool,
The naming conventions agree,
but they only list the M7KJ model.

I feel I basically have enough information now
to source an equivalent DC/PWM compressor.



Wow, Google's WebBot's sure are very fast at crawling the web,
I posted last night in two forums, and today both were indexed.

As PDF's and website's disappear almost daily it seems,
I have copied any relevant text for future Googler's...
