Hotpoint gas oven temperature fluctuation.

Generally the oven temperature will fluctuate as much as 30 degrees above or below the set temperature. The longer the oven is on, the less the temperature fluctuates. If you measure the highest and lowest temperatures readings with a thermometer after the oven has been preheated at least 20 minutes, you should come up with an average temperature somewhere within about 10 degrees of the set temperature. You can calibrate most ovens up to 35 degrees higher or lower if it is off. Any more than that requires replacing parts.

as long as your measured temperature is within 15-25 degrees of shown temp, then it should be ok. remember the temp in the oven will be different from top to bottom.

Hi yitz321,

The F2 error often occurs when the control senses oven temperature above 615F - 630F. The easiest way to correct this is by looking for a welded relay contact on bake or broil relays. If it has a welded relay contact, please replace the oven control. The oven control is the one who measures resistance of sensor circuit, not an actual oven temperature.

Hope it helps.

Thank you for using FixYa.

sounds like you have a bad regulator or oven safety valve

If you are monitoring the oven temperature with an analog style thermometer you may actually be ok, but seeing the thermometers slow reaction time.
Some newer ovens actually do pre-heat beep prior to reaching temp in an effort to conserve eelectricity.
A good home test is to try your oven at several different temps to see if there is any variation in internal temperature. Try it one day on 300, the next at 375 and another day at 450. Give your analog style thermometer time to catch up (usually just about 15 min) and leave it on for a half an hour to see if the temp maintains.
Also Beware of aluminum foil AND THE NEW OVEN LINER MATS as they can alter oven performance bay absorbing and blocking the ovens natural heat radiation and convection air flow currents that happen in all ovens, not just convection models.
Another interesting fact is that older ovens used a thermostat in them that operated much like your thermometer and was very slow to react making the oven typically about 100 degrees hotter than where the customer set it. This was just a fact of life before the advent of electronic temperature management and became noticeable when people began trying to bake older "hand me down" recipes in the newer ovens with less than stellar results.
You can mimic the older oven performance by preheating the oven about a hundred degrees higher than called for and after it reaches temp, re-set it to the correct temperature and put the items in right away.
If you find your temperatures fluctuating ask your servicer to replace first the temp sensor and as a last resort the control board as this part is usually pretty expensive.
Good Luck with this!

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.

no stove holds a true temp they all fluctuate temperature depending on how well it is insulated.

No, that is just fine. As a matter of fact, older ranges often had 50 to 60 degree swings in temp. Your oven temp (assuming your thermometer is dead on accurate) is 347 + 365 / 2 = 356 degrees when set at 350. I never mess with ovens which are within 10 degrees of set temp. (when checking the temps, make sure to take the readings after the oven has cycled on and off at least three times, and use a good digital oven calibration thermometer)

Good Evening.


I would make sure that the conversion kit was the correct kit for your stove. Also, if it is not heating properly I would call the gas company and tell them the conversion did not work and they need to double check their work (at no charge). If everything is in order proceed to the next step below.


You can try removing the Oven Temp control. There is an adjustment on the knob which will vary the temp + or - 75 degrees F or so.

Procedure: Preheat your oven for 350 degrees F. Give it a good 1/2 hour to 45 minutes and then pull the knob off (usually held on with a set screw) You will need a thermometer that will go up to 500 degrees (I use an electronic one but you can use any kind as long as it is within the ovens temp range. If the oven is underheating simply turn the oven control stem to a higher setting, say a 50 degree incrament. Wait another 1/2 hour and measure temp inside oven. Keep in mind when you open the oven door it affects recovery time, etc so 30 minutes between a measurement and adjustment should suffice. Once you have adjusted the temp control to your target temp of 350 degrees look on the back of the knob and see if there is a stop adjustment. There is a chance the temp control knob could be setup differently but the same philiosphy/procedure will be similar.- the adjustment could be on the stem itself instead of the knob.

Also keep in mind that the oven temp will fluctuate from high to low as it tries to adjust to the temp it is set at. That is why it is very important to give the oven time to cycle low to high when you incrament the temp control. Hope this helps and good luck! Gary

you might have already thought of this, buy an oven thermometer you can pop in the oven.
I bought one from my local cook shop
I have a the same cooker and similar problem - mine gets hotter by 50 degrees so I set the temperature 50 degrees lower than needed.
I noticed the problem a few years a go and luckily hasn't got any worse.
