Here are the run times for my CA1 form A, serial 6003376 (rebuilt tag). Cabinet Temp 30 degrees Room Temp 76 degrees On @ 14 degrees evaporator Off @ -2 degrees evaporator (measured at thermostat capillary clamp, this is the actual temp the control senses) On Time is 14 minutes Off time is 15 minutes Times are always better with a heavily frosted evap like this one!! View AttachmentUnless I did my math wrong, my CA-2-A is running 18 minutes per hour and your CA-1-A is doing 28 minutes per hour? Is your actual on time 14 minutes or is that a typo?

Run times as of this afternoon. The off times are still improving, just under 10 minutes now. Chris, How do you collect run time data? I sit in the kitchen with a stop watch and figure there must be a better way. Thomas Just using the stop watch on my cellphone and hitting the "lap" button each time. Then, I edited the photo in MS paint.

Something is very wrong there. Should be under about 4.5 mins.

Something is very wrong there. Should be under about 4.5 mins. I'm thinking it's either a typo, or his -2F evaporator temp. I recall my CA machine going below zero, but I thought it seemed to be pushing the envelope at the time.

i went back and checked and actual room temp is 81 degrees and box temp was 27 degrees today. it takes a lot of run time for a CA 1 to get that cold. And this one is probably a bit overcharged since the cap tube conversion. Off time is very good for such a cold box.
But soda is just right!!! Full of ice crystals when you pop em open

Full of ice crystals when you pop em open Do you worry about compressor wear? That's my main concern, not the $1 extra in electric to run it super cold. I don't want the poor 82 year old compressor to die on me.

Yes I am always concerned about the long life of my Monitor Tops. But this one is still in testing and the charge still needs adjusting. Once all is finished it will always be in a 73 to 75 degree space and i won't run the box that cold, probably keeping it at 32 degrees. But the 15 minute off time is great and I much prefer long cycles over short cycles that result in more on off starts per day, which has been proven to cause more wear overall. If this one gets selected for full restoration it will get a spray foam insulation job and new soft door gasket.

Allan,
Do you use those icecubes, or is that tray there just for ballast? My evaporator is empty.

Evaporators are designed to make ice and frozen desserts for company. They were proud of their ice making capacity. I would think a full evaporator would improve your run times, if you were concerned.

Running a cold cabinet temp (not sure how cold yet) set to #8 which is likely more like #9 per the original calibration I'm seeing 6:30 on 12:46 off now. For such a cold cabinet temp I'm kinda happy now.

I'm getting a little over 30 mins off time, about 3.5 mins run time and a cabinet temp of 28F in the CA-2. The catch is the kitchen ambient temp is 6C! It's the coldest winter since 1995 they say.

I'm sure the CA is having a hard time dropping that 2 degrees. Don't you have heat or air conditioning!?

Yeah it's almost not worth running the fridge! When I'm not a home I don't have any heating on because of the cost. I have a slow combustion stove I use when I'm at home all day, but it takes a couple of hours to get the temp up, so I freeze in the mornings before I go off to work. Aside from that I use electric heaters but they're no good for whole house heat at only 2.4kw.
