Are you referring to the compressor not shutting off down below or the evaporator fan inside the cooling area not shutting off? Evaporator fan always runs the compressor is controlled by the thermostat you could have a bad thermostat if the compressor never shuts off.

Did you fit a manufacturers original or an after market model?

You should clean them condenser coils and check the fan motor. That is something that is fairly easy to do. Get some coil cleaner from ace hardware and go by directions. Check that fan motor. If it ain't going while the compressor is going that is your problem. If you need further help, reach me via phone at https://www.6ya.com/expert/dan_73bbd84fe1d95b61

Jeremy, after the line and new filter drier is put in the high pressure side and silver soldered make sure the unit is placed in absolute vacuum for 30 to 60 minutes. It's critical that all air and moisture is remove and the charge applied on low side with out a single air bubble put back in. You may need some on hands help on this solution to get the cooler working properly, Thanks Sea Breeze 

Question edited for clarity. The Service Manual says that the wiring diagram is hidden in various parts of the unit. https://www.manualslib.com/manual/1177583/True-Gdm-Series.html?page=43&term=wiring+diagram&selected=1#manual It doesn't appear to be all in one place, but you could contact their Customer Service, or Technical Service Department? https://www.google.com/search?q=true+gdm-35em+wiring+diagram ..

If the left-hand door of your True TBB-3G fridge is sagging and creating an air gap at the bottom of the frame where it meets the cooler, here are some steps you can take to fix the issue:

1. Check the door hinges: Inspect the hinges on the door and the frame of the fridge. Look for any damage or wear that may be causing the door to sag. If the hinges are damaged, they may need to be replaced.
2. Adjust the door hinges: If the hinges are in good condition, try adjusting them to see if this resolves the issue. Use a wrench to loosen the screws that hold the hinges in place, and then adjust the hinges up or down as needed to align the door with the frame. Tighten the screws back in place when you are finished.
3. Check the door gasket: If the door gasket is worn or damaged, it may not be sealing properly and causing air gaps. Check the gasket for any damage or signs of wear, and replace it if necessary.
4. Check the door closer: The door closer on the left-hand side may be damaged or worn, causing the door to sag. Inspect the closer and look for any signs of damage. If it is damaged, it may need to be replaced.

If none of these steps resolves the issue, you may need to contact a professional repair service to help diagnose and fix the problem.
