What is a clixon
Clixon is an overload device designed to shut off current when too much juice is flowing within circuit. When it cools it resets itself but if condition is still present it will go out again.
On freezer True T-23, the compressor works around 5 minutes and turn off for around 5-6 minutes and start again for another 5 minutes. I need help
That is what it is supposed to do. It is called cycling and switches off when the set temperature is reached. It is a commercial freezer, so if the door opened and closed often, that is normal?Commercial freezers and fridges have an item called a 'Clixon' that cuts power in the case of the compressor overheating. When was the last time the fins on the compressor coils were cleaned? Could also be a bad door seal letting cold air escape. When you close a freezer door on a unit like that, it should be really hard to open straight afterward due to the suction. Could be a faulty thermostat. Turn the temperature to the warmest setting and see if it still does it? If it does, you need a new thermostat.I just retired after 52 years in catering.https://www.katom.com/598-T23F.html?gclid=CjwKCAiArbv_BRA8EiwAYGs23PKtEzF60_OMVNpHXBlGjHQNdpp0pDZsu0G0lFLqVy2p4qIybG9n8xoCwEMQAvD_BwE..

I have a True Freezer Model T-49. It works fine but every 3 or 4
This sounds like a stuck relay to me. I have seen this problem before. The defrost clock kills power to the compressor relay coil during defrost. If the contacts in the relay are welded together the compressor runs while unit is trying to defrost. On newer units this relay is mounted in base of unit on the side or back of the electrical box near center bottom of unit. The compressor relay is a small rectangular box with 4 wires attached. It can be replaced with a single pole 20 amp contactor with a 120 volt coil/ or 240 volt. Check the units name plate voltage rating and ratings on old relay! ;)
Why is jenn air jcd2389ge hot around front freezer door frame?
The heat at the opening of refrigerator is usually a sign the condenser coils are dirty. Check the condenser coils for a restriction underneath the unit. Dirty condenser coils will cause poor air flow over the coils and compressor. Poor air flow will cause a lot of problems, including overheating the compressor, the refrigerant and the copper lines. This will destroy your sealed system. The coils need cleaning at least once a year, more often if you have pets.
I couldn’t determine if your unit has an “energy saver” setting. If so, turn it on. Not all refrigerators have energy saver. This is on units with emilion heaters in the wall around the door gaskets. The heaters are to eliminate condensation around the door. Turning ON energy saver turns OFF those heaters. You should notice a change quickly if it’s the heater causing the heat, that is, if you have that model.
Cleaning the coils will need a day or two to allow things to cool down before you notice a change in the heat around the door.

True 49f fans stopped running.
Compressor still runs. Fixes? Troubleshooting steps?
I am assuming you are relating to the evaporator fan(s) not running. If this is the case, some units have a 'Klixon" type thermostat in the evaporator so when the evaporator coil temp reaches a predetermined temperature, the fans come on. You may have a bad "Fan Delay" (Klixon) or the coil is not reaching the proper temp to activate it to turn on the fans. I would check the wiring diagram on the unit for this part to see if this unit has it in the system.

True Fridge Running Hard
I would try this: unplug unit and use a vacuum cleaner and vacuum out the entire area. Not sure what you mean by "running really hard"? If you mean noisy, then see if you can see source after cleaning. Try this and let me know if I can be of any further help.
We have a True TS-49F freezer that the interior
Most all commercial freezers like yours have, what is called, a fan delay. It is located in the evaporator case and is usually attached on or very close to the actual cooling coil. It may also be a combination switch known as a defrost terminator/ fan delay. It's purpose is to keep from circulating warm air. If the cooling coil does not reach a preset temp, the fans do not come one. Another thing is that the fan motor may just be bad. If you have more than one fan, then chances are that it's going to be the fan delay. I would start there to see that either the fan delay switch is bad or there is a reason that the coil is not getting cold enough to activate the switch.
