Oven Element Damaged

The metal sheath on the oven element has a small fishmouth crack in it. You can see the interior element glowing when it is on. I know I need to replace it, but is it an immediate safety hazard?

You need to replase it SAP, as it is in imminent danger of blowing up, and causing a short circuit, with possible damage to oven interior.
I strongly advise you not to use it until it is replaced.

How to bypass thermal fuse block to see if oven will heat up


Hello Andy;

My name is Peter. I am a retired field service appliance technician.

I am sorry for the above response. Some advisors on this site are not knowledgeable in the field and answer questions regardless of professionalism and rudeness just to build up points on this site.

Anyway, I am here to help you.

First you have no thermal fuse and you power is 220 and 240V.

There are only three components that control your oven:

1.0 The heating element - Inspect the heating element (Metal bar) inside your oven. Is there a crack in the element. Inspect the two connectors of the heating element against the back wall for corrosion. When you turn the oven on do you see sparking? Then you have a bad heating element.

2.) Ok, the heating element is good.
3.0) Turn on your broiler. Does it glow bright red? Then your thermocouple is good.
4.) Then your problem is in your oven control board. Sears will cost about $256.00.

I just purchase a remanufactured oven control board over the internet for my customer for $30.00. Easy repair.

Send me your model number. Either on the top of your oven door or on the face of your oven after you open the door.

When the oven cut on then it cut off


Oven comes on and off intermittently or heats very little:

If the timer feature is activating and you have not touched the timer button at all, this would have to be a failed Electronic Oven Control. The timer button is either shorting at times or closing on its own from heat or moisture. The Electronic Oven Control would need to be replaced to repair the problem.

Or Why does it take the oven so long to bake?
When the food is taking way too long to bake, it's probably a weak bake ignitor. Replacing the ignitor usually fixes this problem, but you probably want to verify that the ignitor is the problem before replacing it.

Sometimes the oven thermostat or oven sensor can be calibrated wrong, or it may be faulty. If your particular range has an oven that uses an electronic thermostat, and the oven temperature is off by tens of degrees, you probably have to replace it.
On most units that have a mechanical thermostat, you can actually remove the thermostat knob, and adjust the knob to more accurately represent the actual setting of the thermostat. On many models, there's a screw on the back of the knob with a small calibration plate or ring. You can loosen this screw and adjust the calibration plate. Remember to tighten the screw again. If yours isn't adjustable, and the temperature is off by a large amount, you should just replace the thermostat.

Or Oven safety valve needs to be checked with multi meter ohms / voltage

ALSO Test the Burner Heating Element The stove's burner heating element is a coil of metal sheathed in an insulator. Electrical current travels through the element. Resistance to the passing of electrical current causes the element to heat up. A precise temperature cannot be set for a burner, instead it is turned on and off repeatedly by the control to the achieve an average temperature. When it is set to a low temperature, the element is cycled on and off more frequently. For high temperatures, the heating element is energized longer with fewer on and off cycles. Some burners have two elements, with the second only being used only for high heat settings.
Before testing the heating element, unplug the appliance or shut off the power at thefuseboxorbreaker panelto avoid an electrical shock hazard.
When a burner does not heat at all, or only heats up to a lower than expected temperature, the problem is likely to be with the heating element, the temperature control switch, or the wiring. If it only heats at the highest temperature, the problem is with the control or an electrical short, not the burner. If the burner works only intermittently, the problem is likely in the wiring or connectors. To test the heating element, try the following steps.
First, disconnect the heating element from the stovetop. In most cases, this is done by lifting up the burner on the side opposite of the terminals (the part of the burner that disappears under the stovetop). Remove the decorative ring.
Inspect the style of connection. If the burner element has visible blades that fit into the receptacle block, pinch the block with one hand, and pull the heating element free with your other hand. If the terminal block clamps over the element, the housing must be removed and the burner wires disconnected. Unsnap the metal piece or remove the screw that secures the receptacle block and then disconnect the element.
Inspect the heating element. If you find bubbles, warping, or damage to the insulation sheath, the burner must be replaced. If the terminals are dirty or corroded, this can cause poor temperature control, intermittent problems or complete failure to heat. Clean the terminals with steel wool or very fine sand paper to restore good conductivity.
Test theresistanceof the heating element using amulti meter. Set the multi meter to the ohms setting X1 and touch one probe to each of the terminals. A normal reading is typically somewhere between 20 and 120 ohms. The exact reading differs by manufacturer and mode. If the meter reads infinite resistance or the other extreme of the scale, zero resistance, then the element is damaged and should be replaced. If the measured resistance differs significantly from the expected range, the element is probably bad, but if possible, determine from the manufacturer what the actual resistance should be.
To test for a grounded or shorted element, touch one probe to the surface of the burner and the other probe to each terminal in turn. If you get continuity at any time, the heating element is defective and should be replaced.

Dbl Wall Oven 790.4777.3400 Top Mount begins to heat but then shuts off like the cancel was pressed. Replace thermostat, overload, control panel, and control board. Any other ideas?


The oven safety valve
(also called the gas valve) is the part that ensures that gas is not released until the igniter has reached the correct temperature needed to ignite the gas. While this part can fail, it is uncommon. If the hot surface igniter does not glow you should first verify that you have voltage to the circuit. This is a live voltage check and should be performed by a qualified person. If voltage is lost at the valve terminals then you should verify the continuity of the bi-metal in the valve using a multi-meter.

The oven burner igniter
commonly known as the hot surface igniter is used in modern gas oven burners to open the gas valve and to ignite the gas. As the igniter draws electric current it will heat to a high temperature and glow, as well as cause the bi-metal in the oven safety valve to warp and open the valve releasing the gas to be ignited. This sequence normally takes about a minute. Igniters come in both flat and round styles and are very fragile. If the burner does not light then you should check the igniter first. If the igniter does not glow at all, then check for power to the circuit. This is a live voltage check and should be performed by a qualified person. If power is present then the igniter may be open circuit and can be checked for continuity with a multi-meter. If the igniter is glowing, but the burner is not lighting, the igniter may be weak and still be at fault because it requires a certain amount of current draw to open the valve. This check requires the use of an amp meter and should be performed by a qualified person. If the igniter is defective then it must be replaced.

Why is the oven temperature incorrect?

The oven temperature control is usually controlled by a thermostat that uses a capillary and liquid filled bulb. When the bulb's liquid gets heated up, it expands and puts pressure on a diaphragm which opens and closes a switch that controls the gas to the burner. Just set the dial to what you need the temperature to be. Over time, it is possible for your thermostat to lose its calibration. Sometimes, the thermostat sensing bulb comes loose from the holder. If it is out of place, the thermostat may be getting faulty readings. If this is the problem, re-aligning the bulb properly will take care of this problem.

Digital display models use a sensor to control temperature. If this is faulty, replace it. Other ovens use a mechanical system to control the temperature.

On many models, you can adjust your oven thermostat using a small screwdriver. The adjusting screw is located on the thermostat valve stem. Remove the knob and you'll see the screw underneath it. You want to turn the oven on and run it through at least two cycles while watching a calibrating thermometer in the oven for high and low temperatures. Adjust the screw as necessary to fine tune the temperature.

Some models don't have an adjustable thermostat, and you will have to replace the thermostat if you want to resolve the problem.

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.

I turned the bottom oven on and it was like a small lighting bolt went off, it tripped the fuse box to the house and now only the top oven works?


You will probably find that the element for the lower oven has expired. They sometimes do go in a shower of sparks. I once had an element on a hob explode in my face and a small lump of red hot metal flew up and just missed me.
It is easy to get to the circulatin fan and element, you just have to remove the 4 self tapping screws in each corner of the fan/element cover for the cover to come off. If the element has burnt out as you say you should see some evidence of burn marks/holes on the element.
The bad news is that you will have to take the whole oven out of the housing to remove its top and back to gain access to the element retaining nuts and the wiring to unclip/reclip it.
Try espares for a replacement element and if it was a major bang when it went, you should consider replacing the thermostat as well as this is often damaged by the element going.
(The thermostat is the long thin metal rod in the top right hand corner of the oven and is connected to the control by a very thin fragile pice of wire - be careful)!

Oven element has small area that is glowing red when the oven is turned off. the area that is glowing red has a crack in it. is this just a damaged element or is the switch going bad


Hi, It is a bad element. There is also a change the element cause the switch to short out too.
Is this a top burner or the bake element?
If it glowing while the power is off at the switch, check and see if part of the element is grounding against the stove.
I hope this helps. Please let me know if I can assist you further.

Bottom oven not working


A tripped breaker or blown fuse on an electric oven or cook-top, combined with an element that has stopped working, is usually a sign of a shorted, then blown (if the fuse or breaker no longer fail) element.

If you know how to use an ohmeter, you can pull the element, disconnect the wires from each end, then measure the resistance between each end of the element, and each element to the outer sheath.

A good element has just a few ohms of resistance between the wire connection points, and infinite resistance from the wire connection points to the outer sheath. Any readings other than that means the element is bad and need's to be replaced.
