Hello my freezer is not cooling properly and the defrost timer is . making a loud buzzing noise. Please help


Your freezer compartment will freeze up and not cool properly if the defrost timer does not allow the unit to go into its self defrosting mode to get rid of the ice that serves as an insulator.

Replace the timer.

True freezer model t -23f need wiring diagram


There is a safety cutout on the evaporator that sometimes goes open circuit, stopping the heater coming on in defrost.If the compressor will not turn off, check the condenser is clean.and the fan working. next check the thermostat hasn't broken. Lastly, check the defrost timer.

We have a true single door freezer, it is iced up inside . what should the dial inside the unit be set on.


On the freezers a setting of 7 or 8 should do fine. I would be more concerned with the defrost timer, defrost heater, and settings. Also a HUGE problem is that the door switch on the top center of the door can sometimes barely contact the door (this happens when a unit is slightly warped or out of level) or the spring loaded hinge on the door can break causing the door to stay propped open at times. When the door doesn't close the evaporator fan stops but the compressor will continue to run. I have had to tape a nickel on top of the door to make better contact with the switch. Make sure the switch isn't the problem before going any further.

The fan on my true t 23f does not run. i check it is not getting power is there a fuzz or capacitor for this thanks


Are you talking about the fan inside the freezer? If yes, check the following items. The door has a switch that turns the lights off when the door closes, it also turns the fan off when you open the door. If it isn't working right the fan won't come on. There is also a round temperature senser on the coil inside the freezer called a "clickson" that keeps the fan from coming on until the coils are below 20 degrees, it may be bad. If you are low on freon, your coils may not be getting cold enough to trip the clickson. Feel of the small copper line going from the compressor to the coils on the outside of the freezer. It should be almost hot enough to burn your skin if you have enough freon. One other thing to check is the defrost timer. It is a box about 4 inches wide and 8 inches tall with a door on the front of it. Check the connections inside to be sure you are getting power through to the fan. Let me know how it turns out.

Is it factory new, never been used? Or are you saying you bought a used one and they replaced it with a "new" used one? I am familiar with True Manufacturing and if it is a new unit you have a one year parts and labor warranty. The dealer you bought it from is the responsible party to fix your problem.

My freezer will freeze for about 2weeks then it starts to get warm when I turn it off for about 6hrs it will refreeze


It sounds to me like the defrost isn't working somewhere.It freezes for 2 weeks until the evaporator coil freezes over and you lose your airflow, hence, your cooling. Then when you shut the unit off for 6 hours it thaws out enough to get you cooling again for 2 weeks.Check your defrost timer and see if it is going into defrost and if your defrost elements are good. Both will be located on top of the unit. Good luck!

True Freezer- The 5 amp circuit breaker trips when the light on


I believe that breaker is actually for door frame heaters. Most true freezers have a resettable breaker for the door perimeter heaters only.

Convert freezer to refrigerator


Converting a freezer to run like a fridg can be done ,however it is sometimes tricky. you have to replace the thermostat, you will also want to shorten the defrost time setting. and may have to disable the fan delay to let the evaporator fans run all of the time, to prevent short cycling of the compressor.
