I have true freezer t-19 that's not getting cold.it turns on but that's about it

A surge protector for a freezer is a good idea. To conserve energy? On paper it looks good but seriously only real savings are on bigger equipment.

Thermo fuse has failed on the core plate, tells the freezer its cold enough to start blowing air, you can bypass it but not recommended. hope that helps, Russ

If you have just turned it on it takes awhile for the fans to come on. The evaporator coil has to get cold about (10 to 20 degrees) and make a klixion fan switch to turn the fans ON.... Is the evaporator coils getting a frost pattern on them??? If not then the system may be low of Freon.. If the coil is completely froze up and you are getting frost back to the compressor..... then you have a bad fan switch or a door switch.... If you have a wiring diagram you can trace out the wiring.... It is usually down by the compressor or control panel... hope this helps.

Coil must be cold enough for the fan delay to turn fans on. If it is and no fans replace delay

You have a loose wire,or the temp control makes contact when you hit it

You need a cold control. (easy to change)
Its where you turn it colder or warmer.

Hi, sounds like your defrost clock is stuck in the defrost mode. On most true boxes they have a paragon defrost clock with adjustable pins you can set the amount of cycles and duration of the defrost cycle. Find the clock and give it a turn in the direction of the arrow or cw. It will come out of defrost and start to freeze again. If it continues, you may need a new clock. Let me know what you find. Keep me posted. True boxes are top of the line
Sincerely,

Go to this web site and look in the manual on page 15. Check "Compressor runs but will not refrigerate". Gives some suggestions.
Now, inside the evap, usually strapped or clipped to the coil "U" turn on the end of the coil, is a Klixon device. This device comes in many different configurations. There may be 1 or 2 of these. One is a defrost termination switch. When evap gets hot enough so no frost is present, it terminates the defrost cycle. The other is a fan delay. It comes on when the coil temp gets to about 20 degrees. This prevents circulating warm air from defrost cycle. Now if there is only one device, it can be 2 in 1. That is, a defrost terminator/ fan delay. Will most likely have 3 wires going to it where as the 2 separate ones will only have 2 wires to each one. Now, either this fan delay is not working correctly or the coil is not getting cold enough. When it gets cold enough, it turns on the evap fans. This is most likely where your problem lays. Check it out.

Go to "truemfg.com". You can fill in your info on the home page and gain access to a 24 hour, on-line tech support. Worth a try.

thermostat is stuck closed, if not compressor relay is stuck closed, if not then the defrost timer is stuck closed. test the components in that order.
