I have the same problem with my CK 1-15 A16 So far I’ve been able to keep it going but often have to do the hot water trick, wait overnight, prey, ect then it will be o.K for a while. After watching David’s video..I suspect I may have something very similar going on with my ok’d girl. One day I fear I’ll not be able to unstick, and I’ll have to send off to David. (I’m Unsticking tonight) I probably need to start thinking of the logistics of how to get it to David from Ca. Hi Stan. It's a shame that you are facing this problem with your CK. It seems to be more common on the CK-1x size machines. Not sure why but I have a hunch that the very short run cycles caused by a full size compressor on a small cabinet might be part of the reason the larger CK machines don't seem to have the same problem. As you can see in the video, Steve built a heavy-duty crate and sent Monty here via a freight carrier. It was held for pickup in a town about 30 minutes from here, where I went to retrieve it. |

Thanks David
I’m going to have to look things over to fashion a crate for shipping and locate shipping station ect
My old girl is running but as you know, I have to periodically use a hot water pan and a hairdryer on a room temp evap. Then wait a while to turn back on. On occasion it doesn’t work and have to shut down wait a few hours and do the process over. Then she’s alright for a couple of mos.
But when she acts up..it’s the same symptoms.. where just the back frosts up, and machine can’t cycle off due to no frost reaching the temp tube.
Somewhere here in the forum I believe there is a building plan for building crate. I need to get busy so the crate is ready.

Very nice work ! Always like watching your videos and I appreciate your time and expertise on the monitor tops.
Was interested in how you restored the contacts on the starter ,did you replace the contacts?

Was interested in how you restored the contacts on the starter ,did you replace the contacts? Thanks! I'm delighted you enjoyed the video. As for the start-relay; yes, I replaced the contacts with new ones. The original were about 90% gone. |

Where did you get the new contacts,old motor starters ,or did you build the old ones back up ?

Where did you get the new contacts,old motor starters ,or did you build the old ones back up ? I look on eBay for cheap salvaged industrial panel bits. Often the relays have been used only for low current signal switching, thus the contacts are like-new. These relays have about the same size contacts as the GE relay. It's easier to deconstruct the relay to salvage the contacts from the thin copper strips inside; versus the heavy bars in a starter contactor. At least that seems to be the case to me! |

That’s interesting I have some old motor starters I salvaged from an old pipe plant . Laying around collecting dust I’ll have to drag them out and take a look at them.

ok, so heres the update on my ck. but before i post the results i wanted to say the work david [turbokinetic] did is some of the finest refrigeration work i have seen. the joints, bends, soldering etc. is absolutely 1st rate. not to mention the most important thing of any repair, the proper diagnosis! " cant fix it if ya don't know what's wrong!" from beginning to end the best refrigeration work I've seen! thank you David! now. after putting "montys" head back on and starting it up here's what i have. after a few minutes of running, the entire area of refrigerant circulation in the evaporator had a light ice/frost coating but hasn't changed since which i believe is due to the insul foam insulation i used when putting the cabinet back together. condenser cooling fins were all equally warm to the touch top to bottom. after a couple hours of running the cooling fins were cool when the compressor was on which is expected when the interior of the cabinet is this cold. cycle on and off times seemed normal [ normal for the last 10 years]. the run times are about 2min 30 sec on. the off times are about 20 to 25 minutes [varies slightly]. this is consistent with the last 10 years EXCEPT the temperature setting which had been at "6" is now at "5" which means the unit is running more efficiently than before the repairs. the evaporator stays at about 5-10 BELOW zero. items on the second and third shelf are at about 34-35 degrees. items on the bottom are at about 40 degrees. slightly cooler than before the repairs. i haven't put anything on the top shelf yet but will in a few days. i may need to lower the temp setting first [ from 5 to 4 ] so items next to the evaporator don't freeze. the start and run relays seem a bit quieter than before when closing and opening and work great. the compressor noise when running is almost undetectable as before. for the last 10 years I defrosted the unit about once every 14 months [ i keep a log ]. as things go on ill post the results or changes but i don't see any coming down the pike. this is just my opinion but this is the finest refrigeration work I've seen. thanks David, ill keep posting results and/or changes.

Thank you so much! I am delighted that you got Monty back and were able to get it going on your cabinet. I hope you see many years of service. I get a lot of satisfaction from repairing these. It's important to me that the repair does justice to those who have engineered, built, and kept these machines throughout the decades. |

another update. its been 10 days now. 1 week ago i completely filled all shelves with cans of beverages and bottled water. after 24 hours of the fridge adjusting to all the new items the run times are: ON 2:45 seconds OFF time 23 minutes. that is fantastic! the relays are still quieter than before dave rebuilt them. the compressor is still as quiet as ever and the condenser fins on the top barely get warm [ very little heat to remove from the refrigerant] when the compressor is running. this has been an incredible journey but well worth it. just as a side note a neighbor visited yesterday and noticed monty was back together. after getting an ice cold can of coke off the bottom shelf offered to buy the fridge. he started at 1k and went to 1500. i assured him monty was not for sale. ill continue to post changes [ or not ] as time goes. once again. thank you dave for a job more than well done.

another update. its been 10 days now.... Time flies when you're having fun! I'm delighted that Monty is working well. Thanks for the update! Your neighbor needs to look around for a good-condition Monitor Top to have refurbished! They pop up from time to time. Might help him look! Sincerely, David |

thanks, David I'll ask him. seems the single largest problem to overcome is location. most people wont ship or deliver due to the size and weight. but you never know. i found mine in the desert town of la quinta ca. about a 300 mile round trip for me. almost forgot to mention the temps. upper shelf items [next to the evaporator] average 34 degrees. second, third and bottom shelf average 34-40 degrees. the evaporator itself goes between 5 above and 10 below zero when cycling on and off. ill continue to monitor monty and post any changes but i think its good for another 100 years!
