Slow warm up

if it is an electronic timer temp controller you might want to check it

Hi,
If your electric oven is taking too long to heat or just not heating up right,then check out this tip that will give more detail about your problem.

Oven Problems Electric Oven is Heating Slowly or Poorly

The thermostat and control will have to be replaced

try turning your breaker off for 20 minutes, then try it again,, if this does not help it could have burnt out a element or the main board has went out,,, also make for sere you are getting the full 220 volts to the unit,, this will involve taking the unit out

It could be either . The sensor can be checked with a good meter room temp should be around 1200ohms and change with added temp.

There's a few things that can cause this.

1. Check to see if the both that Bake and Broil elements (burners) are heating up. Check the Broil element in Broil mode.

- during pre-heat the Broil element gets cycled on and off for short time durations to speed up the heating. If the Bake element is not working, then the oven will heat, but very slowly and never reach high temperature.

2. If the elements are both working, then it's possible that you have a bad temperature sensor.

- this is a temperature dependent resistance device that should measure 1080 ohms at 70 deg F (room temp).

3. If #1 and #2 are ok, then the problem is with your oven clock/control unit. We rebuild these at fixyourboard.com.

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!

You will need to check the oven calibration using a thermocouple based thermometer(the one you stick in the oven is not reliable). Electric ovens should keep a near constant tempature so if you have it set to 350 the oven should stay around 350 once temp is reached. Now gas ovens are a little different. Most use a on/off thermostat and that means the temp can vary from 320 degrees to 370 degrees to keep an average tempature of 350. So if it is a gas oven you will need to let it warm-up for 10 minutes then start taking the lowest and highest 5 consectutive readings. Then add the 5 reads together and then divide the number by 5 and it should be within 10 degrees of the set tempature. If it is off by more than 50 degrees then you might not be able to get it back to proper calibration. The calibration methods are different for each range and depend on the type of thermostat you have digital(push button controls) or manual(knob). The owner's manual for your range might contain the instructions or consult the manufacture's website for the instructions.

Try to set it at 500 degrees and see if it goes off at 350. If it does, then it probably needs calibrating. You can calibrate it by taking the knob off and finding a set screw in the stem where the knob sits. If this is not the problem, you may have to replace the thermostat. By the way, check to see if your temperature probe is not touching the wall of the oven. It will give it a false reading. Let me know if any of these things work and we will go from there.

Could be a couple things. If your machine is actually failing either a control board or an oven sensor.

Also measuring the temperature can only be done by a tech unless you have a special tool. Oven thermometers are inaccurate. Plus most ranges should vary temp between 50-75 degrees unless has a feature or the more recent ones keep it between 15-25 degrees.

Try the biscuit test, buy some biscuit, brand not important, i just say pillsbury. Cook exactly as recommended on package. If results are a little overcooked or a bit undercook try a feature called Adjusting the oven temperature or Calibrating the oven. This can be done by following the instructions in your book.
