Here is a series of videos about a 1929 Frigidaire MC-12 Multicold refrigerator. This is one of the first models with a frozen storage compartment and a fresh food compartment in one cabinet.
It is built along the same design as the porcelain AP-series and W-series cabinets. It has a Type AW twin cylinder belt drive compressor and 1/3 HP repulsion-induction Delco-Remy motor.
There aren't many Multicolds left. This one has been well taken care of. It was in use up into the 80's. It had the condensing unit mounted remotely, with only the control located in the cabinet. If I remember, I was told the unit was located in a garage. It was taken out of service and carefully decommissioned and stored away by well-known historian and engineer Bern Nagengast. Bern kept it in his collection for quite a while. I saw it while at his home buying some parts and other smaller cabinets. Fast forward a few years and Travis was able to acquire the Multicold from Bern.
Last visit I made to Travis, we took all the mechanical parts out of the Multicold and I brought them to my shop in Alabama for repair and recommissioning.
The Frigidaire installation and service manual shows a MC-9 (smaller cabinet) and they devote a whole page to it whereas the other cabinets have 4 or more on each page. They were proud of this model!
Notice the MC-12 is wider but similar. This is the one we are working on. Love the two-tone porcelain and heavy-duty hardware!
The Model AW condensing unit in the manual is almost identical, but over its 94 years of existence there have been a few changes made to it during repairs and maintenance.
The unit as it was when Travis got it it:
The evaporator for the Multicold isn't in the manual, but the 60-TF is similar but smaller. It has 3 ice tray slots on the left, whereas the Multicold has the frozen storage compartment plus one tray, and four trays on the right. The manual from which these screenshots came is from 1930, and the MC-12 we are repairing is a year or two older, so there are some things not in the manual.
Note that we have a more-or-less period correct motor, and will be mounting the condensing unit under the cabinet as opposed to remotely at the conclusion of the project.
On to the videos! Hope you enjoy them.
Sincerely,
David
