I've had a True TDD2 beer fridge for 8 years (2 doors, 2 taps). The dial settings inside run from 0 to 9. I've always had it set at 5. It started freezing stuff inside recently. It runs a lot. Coil fins are not clogged. I've always kept a thermometer inside and it would read from 34-46 degrees. It was recently reading 22 degrees. I dropped the dial down to a 2+ and it's still reading about 26 degrees 24 hours later. Do I call a repairman or is there something I could do on my own?

First, call your fridge vendor for service.
*** the following is for information only. ***
* You need a full defrosting as there is ice in your cooling coils.
* Move food items to another refrigerator.
* Do a complete DEFROST of the box. (unplug it.) Expect it to take 4 or more hours. You must wait till all water stops dripping out of the fridge. Keep checking the lower defrost drip tray at bottom of fridge. Dump out water from tray as needed. DO NOT you a hair drier or any other heat source! The heat will warp the plastic. Use a small fan to gently blow into the freezer section.
* DO NOT use an ice pick or sharp object to remove ice! Just let everything melt. (The problem of ice is inside the coils)
* Plug in Fridge but don't put any food in. Set dial temperature to the Mid range setting. Set to freezer venting to normal. Set the refrigerator to mid range. Let it cool down to 0 - 10 degrees and start making ice (in ice maker) If it does not cool down to at least 10 degrees F then call for service. Suspect bad thermostat, Blocked condenser coils, Bad pump, etc. Qualified service tech required to repair.
* Cooling okay? Reload food but don't stuff it in. Leave space between the walls to allow cold air to flow around foods. It will take a day or so to cool down food properly. Note: I may take longer if this fridge is near a heat source like a Hot water heater, Oven, Range, Steam radiator, etc.
* If your still icing up in 2-3 weeks. Then check if the coils are icing up. Defrost is not working. This needs to be checked by a tech. Have him perform annual maintenance.
* Check door seals. Kids leaving the door open? High humidity? * Note how everyone uses the fridge; are they putting hot food in it? Open hot steaming food adds heat and humidity to fridge. Hot food with thaw out other frozen food and build up frost.
* Final, Have a Tech check your fridge. Have them perform maintenance and replace worn items as needed.

Check the top of the inside of the fridge. There is usually a flap door mechanism that sometimes falls off or sticks. This regulates the temp in the fridge.
If I am not mistaken, the True line-up of coolers have a temp control on them that is labeled 0-9.
This particular type of temp control is a coil temp control. I measures the temperature of the coil rather than air temperature.
Always set the control to the warmest setting and move it colder by one number at a time until your product reaches and holds designed temp. Do not go by cooler air temperature as there will be a great swing in temp especially if the doors are used frequently. Always temp the product. In the case of beer, your ideal holding temp is between 35-38°.
If you set the temp control to the warmest setting and the cooler is still freezing product, you will need to have the cooler serviced be a refrigeration tech. It will most likely be a bad control but there may be underlying problems.
With the refrigerator, the fan inside the conditioned space should always run. This is normal for most all commercial refrigerators. Need to check to see if the unit is shutting off the compressor after the conditioned space reaches a good temp, usually 35 degrees. If not, probably a bad thermostat.
Keep a thermometer handy. (adjust temperature control knob accordingly)
Periodically monitor temperatures inside your cooler. (adjust as necessary)
Keep the refrigerator door closed as much as possible to avoid temperature fluctuations
The temperature of the refrigerator compartment is
controlled by adjusting/setting the thermostat control
knob, located on the ceiling of the refrigerator
cabinet.
To start the refrigerator, and achieve maximum
cooling quickly;
• Turn the temperature control knob (using a coin
or screwdriver) clockwise to the furthest
(maximum) setting on the darker blue section of
the graduated control dial.
• Allow the refrigerator to run at this setting for 3~4
hours.
• When maximum cooling is achieved, turn back
the temperature control knob setting to the 2:00
o'clock position on the graduated blue control
dial.
• Correct cooling temperature is a key factor to
consider in storing and dispensing draught beer.
• Optimum temperature for serving draught beer is
between 34ºF ~ 38ºF.(1ºC ~ 3ºC)
• To maintain temperatures ranging between
34ºF ~ 38ºF.(1ºC ~ 3ºC) We recommend the
thermostat knob be positioned at the "2:00
o'clock" setting on the graduated blue control dial.
• To turn off the refrigerator, (no cooling) rotate the
control knob to the "0" position.
Could be the thermostat isn't working and the unit is just running and running all the time. To me that seems the most simple explanation right now. Can you check the temp inside when on the lowest setting for a day, then turn it up to the highest for a day and see if there is a huge difference in temps? Does the compressor motor ever turn off or does it run continuously? Suspect that t-stat...
