The reason its not heating is because you will always have 120 volts on this red wire due to its being connected directly to one side of the in coming power source,its either that you lost the other 120 volts of power coming into the unit,a tripped breaker/fuse/etc. or the control board relay that supplies the other 120 volts to the element for a combined 240 volts needed to heat the element,if you have 240 volts to the connection to the unit then you either a bad control board or the Neutral incoming power wire could be burned off which you need to get 120 volts to operate the control board which operate the relay to supply the element with the required 240 volts to operate

Maytag Oven. The bake do not heat, the broil is ok. what is the problem ?


Look at the wiring diagram... The manual reset Thermal Limiter Switch (part number 74008715), located on the lower rear insulation retainer can keep both elements from working, not one at a time... I would inspect the back of the bake relay for a burnt/failing solder joint. Swapping the BAKE and BROIL leads is an acceptable test, but if you put the bake leads on the broil and still get no heat: check the control relay. If the broil leads will not heat the bake element, you have a bad element or bad connection. Be sure to do all testing of the elements with at least one wire detached so as not to red a back circuit.

Bake and broiler element come on when bake is selected. Why?


Understand that I am not a professional, so this answer is subject to revision by someone who is more knowledgeable.

Where I live now I'm on Natural Gas, but in the past I've had electric stove/ovens. Based on my best recall the situation you describe is NOT abnormal.

When in the Broil mode, the Bake element is NOT on, but the Broil element is on FULL-bore to provide that strong radiant heat required for the Broiling process, AND for the good browning /crusting of the product being Broiled!!!!!

On the other hand, when Baking, not broiling, IF the Broiling element were on high it would provide too much radiant heat to the top of the product being Baked, and would burn the top.

While Baking, by energizing the Broil element in a lower power setting, the Baking process is enhanced with more heat by the assistance of the Broiler element, BUT without the hazard of burning on the top!!!!!

Hope this is right and helps your understanding.

I have a Fridgidaire Model # PLEB30S8CCC wall oven. The broiler works fine. The oven is very slow to heat up, 20 minutes to reach 250. I checked the lower element with a omp meter it read 20. Is that...


Hello there and than you for choosing Fixya
If your oven does not heat, does not heat enough or does not broil, a common cause is a burned out heating element. There are two elements, the baking element on the floor of the oven and the broiling element on the ceiling of the oven. They are about the diameter of a pencil and typically supported by metal stand-offs.
This easiest test you can do is to turn on the oven and observe the heating element. If it glows red, the element is working. When baking, the broiling element may come on to assist with preheating or to maintain the oven temperature. When set to bake, if the broiler comes on, but the baking element does not, the likely cause is a burned out baking element.
When set to broil, the broil element should glow red, but the bake element typically is not used. If the broiler does not glow, it is likely a burned out heating element.
There are other possible causes of these symptoms, refer to our diagnostic page for some other possibilities.
To test the heating element using a multimeter, follow the steps provided below.
  1. Unplug the oven or turn off the power at the breaker or fuse box.
  2. Follow the heating element back to where it goes through the wall of the oven. Remove the bracket that secures the element in place.
  3. Unscrew or unfasten any stand-off supports that secure the element to the oven.
  4. Pull the element part way out to expose the oven's wiring connected the element.
  5. Label the wires and secure them in place so they do not fall back into the cavity.
  6. Disconnect the wires from the element.
  7. Using a multimeter set to x1, touch one probe to each of the element contacts. Expect resistance in the range of 20 to 40 ohms. Infinite or kilo-ohm resistance usually indicates a bad element and it should be replaced.
  8. If the element tests okay, reconnect the wires, slip them back into the cavity and resecure the element.

Oven will not heat, but burners still work


Without model number assuming burners on top and free standing unit.
The burners working tells you there is 240 volts to the unit. There are three possibilities, the bake element is burnt out, a wire is burnt off, a control part has failed. Bake elements can not be pulled unless the power is disconnected, because very often one side of 240 volts(120v) is wired direct so unplug, do not think having all controls off is enough. You can usually pull the bake element fairly easily by taking out two mounting screws and unplugging two wires. (these can go back on either way to the two terminals, does not matter just be sure tight) Take and have tested at appliance store, usually these test about 20 ohms. If that is good need to service from back and check voltages with a meter to find where problem in circuit is.....
good luck

Also check clock it is not accidentally in time bake setting, should be manual for most cooking (do this first before anything else)

The baking element in the oven does not appear to be working


HI.I would test to confirm the actual issue. This easiest test you can do is to turn on the oven and observe the heating element. If it glows red, the element is working. When baking, the broiling element may come on to assist with preheating or to maintain the oven temperature. When set to bake, if the broiler comes on, but the baking element does not, the likely cause is a burned out baking element.When set to broil, the broil element should glow red, but the bake element typically is not used. If the broiler does not glow, it is likely a burned out heating element.


Use This procedure below to confirm the failure.

With a multimeter, use these steps below to physically test for element functions.

1. Unplug the oven or turn off the power at the breaker or fuse box.

2.Follow the heating element back to where it goes through the wall of the oven. Remove the bracket that secures the element in place.

3. Unscrew or unfasten any stand-off supports that secure the element to the oven.

4.Pull the element part way out to expose the oven's wiring connected the element.

5.Label the wires and secure them in place so they do not fall back into the cavity.

6.Disconnect the wires from the element.

7.Using a multimeter set to x1, touch one probe to each of the element contacts. Expect resistance in the range of 20 to 40 ohms. Infinite or kilo-ohm resistance usually indicates a bad element and it should be replaced.

8.If the element tests okay, reconnect the wires, slip them back into the cavity and re-secure the element.

Oven wont heat


Hello, It could be that the EOC is bad but have you checked both sides of the breaker? as you may already know the 220v is on 2 breakers, although you may see the clock still working you still have 120v to the control side, the 120v breaker for the heater side of the cuircuit could have popped...If after checking the breaker you have a full 220 then I would have to say it's going to be a problem with your EOC or high limit if this model has one.

I have a brand two month old GE 27" wall oven. It takes a very long time to pre-heat, sometimes up to 30 minutes for 350. Any ideas? Is this normal?


check your power connections, do you get 240 volts between red and black, 120v red/black to white? at outlet and in unit

Wont heat past 200 degres


When the food you're baking is done on top but not on the bottom--or when baking just takes far too long to finish--the bake element may be burned out.

You may get fooled into thinking it's working, because the oven is hot inside. But many electric ovens use the broil element, too, during the preheat and bake cycles. So the food may be getting heated only by the broil element, which causes poor baking results.

If the bake element is burned out, replacing it should solve the problem. Otherwise, you need to further troubleshoot the oven's electrical system to locate the defective wire or component.

Electric Oven Won't Heat


Rob, sounds like it was just installed. You need 240V on this unit. On the terminal block in back where the power hooks up, it should read 240V across the two outer terminals and 120V from each end to center terminal. Im ruling out the thermal cut out because you never used it. I would start with the power source first. The display sounds like it's getting the 120V it needs to funtion, but I don't think your making the loop for the 240V needed for the bake and broil. Catriver.
