Red black and brown means defrost termination/fan delay.

yes..i know, i have a system that the fans wont come on, evap is frosty and i think they should...i have a new one, but would like to trouble shoot it before i replace it!

t-49f it also has a klikson with 2 small black wires that is attatched to the ceiling of the box..

the other is defrost safety.

klickson should have the temperature were it operates on it, it also could be wired in wrong.

did you check the plug in connection for the fans? then come loose and get corroded.

Here's the wiring diagram for that box.

Check your door switches also. I've seen lots of problems with those.

Heat wiil show Def. term the other side depends on temp setting but a walkin freezer should do it

Ok, turns out my fans didnt come on because the grassland timer relay failed..there was a big black spot on the back side of the solid state timer..

timer was noisey when i showed up the 1st time..i should have checked it out 1st....*gulp*

I am a True MFG authorized warranty rep. These defrost timers are the first thing that i check....

On True units with defrost timer, the left upper screw is within 1/32" to the pc board high voltage circuit and if it gets just a hair inward towards the screw head, well, your done. to a direct short making timer useless for much more than a timer.
