OVEN DOESN'T PREHEAT

Hello Debbie - Sounds like the unit has loss some of its heat inside of the oven cavity. This means it cannot reach the proper preheat temperature in the programmed 30 minute timeframe. A technician would be required to further diagnose this concern. They would most likely assess the convection heating element, thermal cutout, thermal oven sensor and all wired connections for repairs. Lastly the oven cavity and insulation should be checked to ensure there are no gaps or damages that will leak out the heat. At t his time, I would recommend contacting a professional to assist you further.

I have a Kitchen Aid convection wall oven. It takes 6 - 7 minutes to preheat to 325 degrees. You probably have a bad element. There are 2 elements.

Your oven sensor has gone bad and telling the control board/thermostat to keep heating. Find the model number on the range and go to a parts distributor like repairclinic.com or apdepot.com and order you sensor. This is an easy repair.

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.

Either your bake element is bad or there is a bad connection going to the element. This is a very high current connection so bad connections are always a possiblity. Also check and make sure your broil element is working as some ovens use it for pre-heat. Do both elements seem about the same temp? You can turn the oven on and carefully hold your hand a few inches from the element to see if they are getting equally hot. If your connections are good to the elements then one of the "calrod" elements is probably bad. You can also check the resistance of each element. Not sure of exact reading but a higher resistance means less current going to the element. Just compare reading on each one and go from there. Good luck!

most common issue, and it sounds like what your experiencing here, is a faulty ignitor, replace the bake ignitor ( located under teh oven floor, attached to the burner bar)

After jiggling the lower burn element the oven heated up in the normal time. Perhaps a connection had come loose.

You obviously have one or more elements not working, you need to test same, and replace as req'd.

Check the BACK of your temperature knob for an adjustment. I was ready to replace my heating elements when I accidently discovered the adjustment. Made the adjustment and no more problems. My oven now stays within 4 degrees of settings.

times quoted seem about right and don't suppose your old oven was much different. element ratings don't vary much for same size ovens
