My oven is very slow to heat up now. It takes an hour or more to heat to temp.

It hard to tell, please let me know what did you see and hear when turn on oven...

Check breakers and elements.

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.

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

I am experiencing the exact same problem. May try to trouble shoot myself if no one provides assistance on this site. It looks like the problem has to do with either the Sensor, Heating Element or etc..

Hi,
If your electric oven is not heating then you probably have a bad heating element in your oven. This is not that hard to fix yourself...

Your temperature control has gone out and this is simple repair!!

I found the bottom element was not getting any power by using a volt/ohmmeter and a test method described elsewhere. (Shut off power, hold down COOK TIME while turning on power. then within 30 seconds press each mode you want to test and only that element/fan/etc will turn on. Cancels by itself after 30 sec.)


I traced the wire back to the relay (wire checked good) and there was no power getting through the relay although it clicked. Removed the relay board to replace it and found a cold solder joint on the "out" terminal with obvious past arcing carbon. Cleaned and soldered the pin and the oven now works normally.
WHY THE SLOW TO HEAT? The oven turns on all the elements to preheat faster and when it reaches your set temp it beeps and now only turns on the element you selected to maintain the temperature. (Bake or Convection) Our malfunctioning ovens would then cool since the element is not working properly and it must go back into preheat and keep cycling.
BY THE WAY- Don't ever use 4 hours on self clean it kills the boards and/or display. I also put a house fan in front of the oven and blow it into the lower grill to take away some of the heat on the two boards. Learned the hard way!

An extremely common problem on these models is a weak silicon carbide ignitor. You may be able to see the ignitor glowing, but that is not an indicator of it being functional or not. When the ignitor gets "weak" over time, it will not create enough amperage in the circuit for the gas valve to open. You can test this using an amprobe around one of the ignitor leads and looking for at least 2.9 amps, but years of working on these appliances has shown that if you are getting the glow from the ignition but the oven is often slow to come on, you need a new ignitor. Do-it-yourselfers often mistakenly replace the oven valve or the oven temp sensor, figuring the ignitor must be good because they can see it glowing.
Replace the ignitor and your oven will work great again.
