What is a laboratory oven?


Wikipedia says" :
Laboratory ovens are ovens for high-forced volume thermal convection applications. These ovens generally provide uniform temperatures throughout. Process applications for laboratory ovens can be for annealing, die-bond curing, drying, Polyimide baking, sterilizing, and other industrial laboratory functions. Typical sizes are from one cubic foot to 32 cubic feet (0.91 m3) with temperatures that can be over 650 degrees fahrenheit (340 degrees celsius).

Hi,

If the refrigerator is not cold enough then please check the following and also click on the blue coloured links for more info.


How To Check the Temperature1x1.gif In most refrigerator freezers, the refrigerator gets its cold from the freezer. The evaporator fan circulates air over the coils in the freezer and cold air circulates into the refrigerator through vents. If the vents are blocked or closed, then the fridge will not get cold enough but the freezer will. If neither is cold enough, then the number of possibilities increases.
Lowering the freezer temperature will increase the cooling cycle activity. Setting the refrigerator temperature may have little affect on the cooling cycles because it simply changes the vent opening size. Decreasing the fridge temperature opens the vents more and increases air circulation from the freezer.
The temperature can be adjusted using the controls found inside the refrigerator or freezer. The ideal freezer temperature is about 0 to 5 degrees (F) and about 38 degrees (F) for the fridge.
Measure the temperature by placing a cup of water with a cooking thermometer into the refrigerator for about 2 hours or more. To test the freezer, substitute alcohol or cooking oil.


Goodluck,

Hi
You have condesation built up in your freezer whereby the evaporator fan or the vents are most likely blocked off.

Turn fridge off. Empty freezer and either put a pot of boiling water inside freezer or with the aid of a hair dryer try to defrost the freezer. If you are able to remove the back panel on the freezer that would be ideal as you can directly target the frost.
Good luck

Hi my name is veronica my problem of my kenmore elite refrigertor is not cold enought...i want to know what is the tempertaure that need to be on


Problems with Temperature
If the refrigerator or freezer is not cooling properly, check temperature settings and air vents and ensure there is adequate room for proper airflow. Factory-recommended temperature settings are 0 degrees Fahrenheit (-18 degrees Celsius) for the refrigerator; and 37 degrees Fahrenheit (3 degrees Celsius) for the freezer.
If you need to adjust the temperature, do it one degree at a time and wait 24 hours before making additional adjustments. Check the air vents and make sure nothing is blocking them. Finally, if your refrigerator or freezer is too full, there will not be adequate room for air to circulate and cool properly. If these all check out, the problem could be with one or more compressor components and will require professional repair.

Have a nice day : )

If you have a combined refrigerator/freezer thermometer, check the freezer compartment temperature too. You should have the overall temperature control set so that you have the freezer at 0 to -5 degrees F. All combined units will (or should, at least) have a control that allows you to divert a varying amount of the cooled air to the refrigerator.
If you need the user guide, I found a good link but out here in the boonies, our connection is so slow, I may not live long enough to download the .pdf file. If you retrieve the manual, check for the settings as I described.

GE refrigerator is cooling to 48 degrees F, but the setting is at 37 degrees F. The temperature on my furnace is set to 70 degrees F. Is this affecting the refrigerator?


The freezer may be overcrowded with food in this case cold air from freezer is not migrating to refrigerator compartment. Inside the refrigerator, at the bottom and on top, there are opening sliding door that allows cold air from freezer to circulate in the refrigerator. Make sure that they are not obstructed. Or simply, your refrigerator condenser is dirty and may need cleaning. If neither of this is the solution, get a repairman to check or fix it for you.

Proper temp. range in freezer


Hi dgh1,
The freezer should stay within 5 degrees of 0 while in operation. While in defrost the freezer may reach as high as 20 to 25 degrees. If any higher temperatures are reached your food will spoil as they are defrosted and refroze everyday. If you find that the temperature is allowing your food to defrost you may want to replace your defrost thermostat. This device is located on top of the evaperator coil inside the back of the freezer. It is made to turn the heater off when a temperature of 55 degrees is reached. One other possible problem could be your defrost timer is taking to long to restart the cooling cycle after defrosting. I hope this will help you and please send any other questions you may have, I am happy to help. and dont forget to rate me.
