Where is the thermostate(sensor) located that controls the compressor - or is it the same as the sensor located by the door which show the temp on the outside indicator Thanks

Freezer too warm. Here is the link to the manual and its troubleshooitng section starting page 20: https://manualzz.com/doc/6492658/defy-f325-upright-freezer-duf-281-owner-manual

If not a matter of door being left slightly open or hot food being inserted or freezer recently being activated, one pursues other possibilities:

Is the compressor running? It is hot? Is the water filter clogged? Does it have a bad switch? Look for reset switch: https://www.youtube.com/watch?v=XstbFK31Us0

Contact a professional. The power supply source needs to be testing to the compressor and see if the power is fine, or if the compressor is faulty and not drawing needed power.

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.

It depends on the control that your freezer utilizes.

If your temp control dial has the numbers 0-9 or 1-9, then you have whats commonly known as a coil temp sensor.


Unlike an air temp contol that measure the air temp inside the freezer and comes on and off with a 3-5° swing, the coil temp sensor runs a little bit different.

With a coil temp control or sensor, the temp control has a capillary tube and bulb that is inserted into the coil either at on of the ends down a guidetube or just into the center of the radiator type fins. This temp control measures the temperature of the coil, and not the temperature of the air inside the freezer. When the unit runs, the coils typically gets 20° colder than the air temp. And when the control satisfies (shuts off), it will not call for cooling again until the sensing bulb has reached the cut-in point which is typically well above design box temp.


So, to quickly answer your question, yes it is possible to have a 25° temp swing and not have anything really wrong with the unit. That is how its been designed to operate and that is how it will operate. Your only option (although not recommended) is to replace the coil temp sensor with and air temp control. That will give you more consistent temps.


Also, when taking temp of a freezer with a coil temp sensor, be sure to temp the product in the freezer and not the air temperature.

compressor relay is probably going out...also check the plug in to the wall. A intermittant contact is a matter of following the source to the compressor. start at the plug and through the temp sensor/ t-stat defrost control and down to the compressor. but ususlly the compressor relay is the culprit.

It can be done but someone would have to do their homework. They have to know the BTU rating of the evap. Then match the compressor and expansion device to it for the intended temp range. In some cases, the compressor can be used in multiple temp ranges, so you could be lucky and just change the expansion device and possible the temp control, depending on which one you have. Let me know if I can be of any further help.

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

You should get a thermometer to be sure the temp is what it should be. With out it is very hard to tell correct temp.

The manual for this unit can be found here.

you have a refrigeration issue partner let her go 16 yrs. is good service you can replace it for 3 to 5 hundred the repair will be that IF you can find someone with the r-12. don't go for a top it off and go deal the food you lose is to expensive for that to be economical.
