How you set the tempature - True GDM-45 Refrigerator

To what ever level your comfortable at. I let mine run in the basement all the time.

Hello,

The F3-E2 error code means that the heated well above the setting the tempature was set at. The usual reason the oven would over heat by so much is a defective oven tempature sensor and the sensor would need to be tested to see if is the problem to test the sensor it would need to disconnected from the wiring to it and measure the amount of ohms of resistiance AT ROOM TEMPATURE when the oven is off and cool. At room temp. the the meter used to check the sensor should display between 1060-1100 ohms,if the number is vastly different that 1060-1100 at room tempature the sensor is defiently bad and should be replaced. This is what the sensor looks like
it will be inside of the oven chamber and again to properly check it the wiring should be unplugged and the meter leads should be placed into the plug at the end of the sensor to measure the ohms.
If after checking the sensor if its within the range of 1060-1100 ohms at room tempature the problem is going to be the control board.


I hope i have been able to help ya fix your oven,

One thing you should know about a gas oven is that they do not keep a constant tempature like an electric oven does. So going by a tempature gauge in the oven can fool you. The way a gas oven works is by "average" tempature. In other words if you take the highest and lowest tempature readings and average them out you will get the actual tempature. For example let's say that you set the oven to 350. Well first it will take about 10 to 15 minutes for the oven to properly pre-heat. Once it is preheated you can listen to the gas burner and watch a tempature gauge(flook meter is best). When the gas burner shuts off the oven tempature will continue to rise. When the oven tempature stops rising then you will take that reading. Then wait for the oven burner to come back on again and watch the tempature gauge. When the tempature gets to it's lowest point and stops then take that reading. Do this several times and then take all the tempature readings and add them together then divide that number by the number of readings you took and that will give you the actual tempature. Within 5 degrees is great but anything over 10 degrees can affect your cooking. This will give you an idea if your oven is out of calibration or not.

There is a calibration procedure. The instuctions are located in the owners manual and can be found here http://products.geappliances.com/MarketingObjectRetrieval/Dispatcher?RequestType=PDF&Name=49-85131.PDF

Just go to the "Thermostat Adjustment" section for the proper calibration procedure.

a rule of thumb for this situation is 20 degress cooler inside you have that but it is still a good idea to have an a/c system serviced every year

service the freon, Sounds like its low

Is this oven gas or electric? If it is gas then it can be normal to see 30 to 50 degrees difference in tempature. The tempature in a gas oven works on the average tempature. For example: The oven tempature may rise all the way up to 370 degrees. Then the burner will shut off. And then the tempature can drop all the way to 330 degrees. Then take 330 and add that to 370 then divide that number by two and the average tempature will be 350. If your oven is electric then the tempature should be much more consistant but can have a 10 to 15 degree variance. Also the standard oven tempature guage that you put in the oven or even the temp guage built into the oven are not very accurate. We us a Fluke meter with a thermocouple to calibrate an oven. So to check your oven for proper tempature regulation you will first need to let the oven pre-heat for about 15 minutes. Then place the thermocouple in the center of the oven. If the oven is electric the take a temp reading every 5 minutes and average them out. If the oven is gas then you will need to take a temp reading when the tempature reaches it's highest and lowest points. Take at least 5 consectutive readings and average them out. You should get an average within 10 degrees of set temp(350 degrees). If it is off by 35 degrees or less you can usually caluibrate the thermostat back to proper temp. This procedure can be different for each range model. If it is more than 35 degrees off or you are getting irratic readings then the thermostat or thermostat components might need to be replaced.

The thermostat will display the current tempature in the room. When you press the buttons to change the tempature and you see it change back it is probably going back to the room tempature display but still keeping the temp you set it at. Also make sure the "hold" feature is set or the temp you choose can change at different times during the day due to the programmable features built into the thermostat.

post your model number please

Buy a candy/fryer themometer. The setting numbers were inaccurate anyway.

if you read your tappan instructions, it will tell you to turn your oven to 550 degrees, then press and hold the bake button for 15 seconds. it will blank out and go to 0. adjust temp up or down accordingly. peace out.
