Have you checked the door switch for each door? the lights should still work in defrost mode but not fans or compressor.

SOURCE: Freezer Not Fan not running!

Most all commercial freezers have some sort of fan delay/ defrost termination device. Commonly called a "Klixon" (pronounced clicks-on). It is a device that is attached to the evap. It's function is to terminate the defrost cycle when the evap reaches a certain temp, say about 50 degrees or so, to ensure there is no build up of frost/ ice on the evap. It then allows the compressor to run, and cool the evap down to a reasonable temp., say about 20 degrees, and then let the evap fan come on. It prevents overloading the compressor during a high temp condition, and it also prevents circulating warm air left from the defrost cycle. I believe this device is most likely your problem. With no air circulating, the box will no cool down.. I have seen them burn and/or slhort internally. They can come apart. too. I would look here for that problem. the True manufacturing website does not give alot of info on this piece of equipment, such as a wiring diagram but manuals are available.
Check this out and let me know how it comes out.

SOURCE: We have a true T49F freezer and the evaporator

Freezers have a sensor that is referred to as a "Fan Delay/Defrost Terminator". It senses the temp during the defrost cycle. Usually, when the evap temp reaches about 50 degrees, there should not be any frost or ice on it. This device terminates the defrost cycle. It also keeps the fans off so warm air is not circulated. When the evap gets to about 20 degress or so, the sensor switches on the evap fans. If the fans are not coming on, either the sensor is bad or the evap is not reaching the proper temp to cause the sensor to turn on the fans.

Hope is helps to clear up some things and point you in a direction as to what might be going on.

My Fridgidaire upright Gallery freezer is freezing my food but the appliance seems to be constantly running and the temperature control on the outside is reading 29 Celsius when it obviously isn't

Hi Susan Abboud - Modern freezers have increased storage capacity and keep more even temperature that may require the compressors to run longer but use less energy. Was the unit disconnected previously for any reason? If so, freezer requires a minimum of 4 hours to cold down completely. Confirm that the temperature control is not set too cold and that the door is not being open frequently. A dirty, cracked, worn or poorly fitted door gasket can allow warm air to enter the unit causing it to have to run longer to remove the warm air. Leaks in the door seal will cause freezer to run longer in order to maintain desired temperature. Cleaned the gasket, if it is too damage then it will need to be replace. You can check and see if the door seal is bad by, placing a dollar between the gasket and cabinet. Check to see if the door is being blocked by anything stopping it from closing properly. If nothing is stopping the door then replace gasket. Keep in mind that there should also be at least 4-6 in of air space on all sides of the unit. If freezer is built in or has items stored on top that cover the unit, the can cause long run times, high temperature in the freezer and premature failure to the unit. Do not block the toe grille on the lower front of the unit. Sufficient air circulation is essential for the properly operation of your freezer, about 3 inches around the unit.

I have a true 2 door freezer with bun rack rails...it is runninig between 7 degrees up to 59 degrees...we vacumed the vents...do we need more coolant or what do you think...it is about 4 years old and...

Vacuuming the coil is not usually sufficient to clean them properly. Hold a flashlight behind the radiator on top of the freezer to see if you can see freely through the coils. If not, the best way to clean the coil is to spray coil cleaner on there and flush with plenty of water. It is a mess but it will get the grease off the coild. If you do not have gauges to check the pressures of the refrigerant (lets call it freon), you can get a good guess by doing the following: Get a ladder, climb up so you can see in the top of the cabinet where the compressor is located. It looks kind of like a bowling ball. There will be one small copper line and one large copper line running from the compressor. The small line is the high pressure line. It should be hot enough to burn your finger. It then goes through a small pan where it evaporates excess water, then to a "radiator" which has a fan running behind it. If the machine is running this fan should be on. The small line then runs into the freezer box. At this point the line should be warm, not hot to the touch. If this is not happening you are probably low on freon. The other copper line on the compressor is returning from the freezer box to the compressor. It should be very cold to the touch. It should have moisture collection on it. If this is not happening you are probably low on freon. Other factors can effect your freezer. Make sure the fan near the compressor is running. Make sure the fan or fans inside the freezer are running. They will stop running when you open the door, so hold the door button in when you check the inside fans. Check also to see if there is a build up of ice on the inside coil. Your freezer should run a defrost cycle 4 times a day to remove the ice. If it has ice it will not run properly. If you can remove your product for 24 hours and shut the freezer down, prop the door open and the ice will melt. On restart if the freezer goes down to 0 quickly (30 minutes) it was probably frozen over. This may indicate a bad defrost timer or heater. Try these things.

Frosting up badly despite having just been defrosted

Hello,

Most times this is a bad cold control, but there are other things to check for. Make sure the condenser fan is working and the coils are not covered with dust. A separated heat exchanger ( small capillary tubing soldered to the large suction line ) can separate from one another and make the fridge run too long. - tape tubing back together. A poor working evaporator fan motor could also make the fridge run too long and freeze - replace the fan motor. An inefficient compressor or refrigeration system could make the fridge run too long and freeze - have a service tech check this out. A misaligned control settings, make sure the air damper and cold control have not been bumped and are out of normal settings. Stuck open air diffusers or air dampers are becoming more and more common for allowing too much air to be blown into the fresh food section and freezing things. On all frost free fridge's the freezer temp air is blown into the fresh food section, if you have "easy" to freeze items ( eggs, veggies in water, etc ) in front of or under where the freezer temp air comes out, they could freeze - store them in a different spot. Doors not closing properly making the fridge run too long is something else to check for cold control and air deflector As you know, the deflector directs the freezer air toward the front of the frig and the rear of the cold control.
Hope this helpout.....

The fridge on my fridge freezer has stopped

just about all friges work off the frezer .the evap fan moves the air fromthe frezer to the frig.so you would here fan noise.i dont know your brand but on most frezers if you turn the frezer temp to the highest setting thats acomplished by keeping the air from going to the frige.hence warmer frig temps .also make sure fan on out side back is working and condenser is clean.again turn air damper control from frezer to frige to lowest setting .somthimes this could be in frig section.God bless ,tom

Unit not freezing , evaporator fan wont run

If this is a Bev-Air, don't think the door switch will control the fan. At the evap, there is a temp sensor called a fan delay. When unit goes into defrost mode, this warms up. Some also serve a dual purpose. It will terminate the defrost cycle at a certain temp., say 51 degrees or so, at the evap. Anyway, when unit comes out of defrost, it keeps the fan off so it allows the evap to cool quicker and to prevent circulating warm air. This could be your problem. Not a hard fix but they can be a pain sometimes. Outside chance that the unit is low on refrigerant (freon). This will not let the evap get cold enough to trip the sensor back into position to turn the fan on. Good Luck. Restaurant Parts and More carry alot of Bev-Air stuff. 1-888-814-1110. Ask for Rick

Kenmore frostless 19 temp. control knob

i've pulled up the service diagram for it and there's no thermostat or temperature control but there's a limit sensor inside the freezer I'm sure that such sensor is failing and when it defrosts, it stays on to long, and the whole 15 min defrost cycles goes on causing the freezer to warm up, delaying the freezing process. I'm almost sure that the limit is going.
