Months ago I made a deal to buy a rough looking DR1 in Ohio. The story was that is had been left by the previous owner of the property in 1969. I got a friend of mine to go fetch and store it. Last weekend I was up that way to pick up the last DR3. It was a complex trip. I met our member Herb, elec573 in Temperance. I gave him a working DR1, got a dead DRB3 from him, loaded the DR3/2 dr and then grabbed this other DR1 in Dayton.
This poor thing had obviously been stored in a semi-open shed. It looks awful. I had recognized it was a form A. I thought it would be good for parts. Upon closer inspection, I found it to have a type D control. I had never seen that one. Lord knows I am a fan of vertical start coils! I grabbed my watt meter and realized the heater was bad. The control wouldn't work right, so I turned it on and plugged the extension cord in. Sadly, it groaned, but nothing. I told my friend that it didn't work and he suggested I let him dump it. No way, I had to try the annie.
So I bring it home with the rest of the haul. Ray got it into the back room. Yesterday I pulled the control off and disconnected the heater leads. I also clipped the old heater and installed a new one on a test cord. I waited a few minutes and heard the gentle sounds of a peculator. I went to bed knowing that at least it had a charge.
This morning armed with the annie and my DR manual, I set out to make it run or part it out. I checked motor resistance and to ground. The windings were there, but there is 15 Mohm to ground. I figured I had nothing to lose so I hooked up the annie and flipped the switches. It fired right up.
It made some odd float noises and barely started to cool. It got louder and at times acted restricted. I then felt some cooling at the rear top of the evaporator. It was rattling like a model T. I filled an ice tray with hot water and let it continue to run. It seemed that more of the evaporator was cooler than room temperature. I grabbed a defrost heater and put that in place of the ice tray. It continued to rattle. I then got sidetracked on the phone. While I was standing there talking, it got so quiet. I wondered if it had quit. No, the condenser was finally warm and the evaporator was fully sweaty. I unplugged the heater, moved it and it frosted.
The control has corrosion and needs a bath in the ultra sonic cleaner. I am so happy to have this weird example.
