Gas oven not heating to temp

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.

You might try calling Sears, or wherever you purchased the oven. Or even an appliance repairman. It sounds like the oven temp needs to be re-calibrated, or buy a thermostat to put inside the oven and follow the temp it says.

Get yourself a COOKING thermometer,like for checking syrup/candy temps,--put it in the oven,turn the knob to certain spots and give the oven time to heat.Take a reading and mark on the knob what the temp is in perm marker.

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.

There is a calibration method to adjust the oven thermostat plus/minus 35 degrees if it is a digital display. The method varies depending on the model range. This calibration method is used to adjust the thermostat if it is not keeping proper tempature. For example if you are setting the oven to 350 and the actual temp it is keeping is 325 then you could use the calibration method to adjust it plus 25 degrees to correct the temp. Just so you know electric ovens will keep a pretty even temp but gas ovens will vary by 40 or more degrees to keep an "average" temp. For example the burner will come on when the oven is 330 degrees and turn off at 370. 330+370 then divide by 2=350. So a oven thermometer may not show you the temp you set it at in a gas oven but does not mean the oven temp is off.

Hi,

The ignitor is not working right and is going bad....
have the repair man replace the ignitor, or DIY....

Oven Problems Replacing the Igniter

Replace the oven temperature sensor.

you need to replace the oven ignitor

after youve cooked at desired temp(400) for allotted time. turn off oven, and restart at 350. it wont start up right away( its already at 400, but it wool drop in temp and cook at 350. good cookin to ya!!!

The fault is either the capillary has fallen away from back or it is a faulty thermostat.
