Kenmore model 66575775890 oven. broiler and bake burners don't work. the igniters do work, they both glow VERY bright and hot

The oven control supplies voltage to the oven igniter/gas valve circuit. When the oven control is set to Bake, voltage is supplied to the oven igniter which should glow bright red to almost white hot. Once the igniter comes on and begins to glow it must pull enough current to cause the gas valve to open so the burner can ignite from the igniter. I added an image below with the theory of operation.

----Open the broiler drawer and then set the oven control to bake and watch to see if the glow bar igniter glows or not. If it does not glow, the failure could be a broken Igniter, failed oven control board or gas valve. If the igniter is glowing red, then it can be possible that gas valve is faulty.

Also to confirm, check to see if the igniter is getting 120 volts when it's turned on. If it gets 120 volts, then your safety gas valve is bad because it's not letting the neutral go through. Otherwise, if it's NOT getting 120 volts, your control board shorted out and you need a new control board.
But as you mentioned that control board is replaced. So igniter should get 120 volts. If valve is faulty. But if igniter is not glowing then its faulty igniter confirmed.

In most of the cases the igniter is faulty, because gas valve getting faulty is very rare. But still getting the voltages checked, will confirm. These will help. Thanks. Helpmech.

Hello there:
It doesn't bake Bake igniter
When the bake igniter becomes weak or burns out, your oven would not bake. The bake igniter is usually mounted on the oven burner. It's about 1 inch by 4-8 inches (depending on the model), and comes in round or flat styles. If you don't see the igniter glow at all, it's probably burned out. Replace the igniter if found defective. Note: one of the exceptions could be that your oven is set to automatic mode instead of manual. If this is the case, set your oven to manual mode and check again.

If the bake igniter glows red and not bright yellow or white, it is probably because it is too weak. When this happens, the safety valve would not let the gas out into the oven burner. A weak igniter must be replaced.

A faulty igniter is probably the most common cause, however there are others:

-- defective thermostat
-- defective selector switch
-- defective gas safety valve

If you are certain the igniter is ok, it might be a good idea to call a professional appliance technician.

OK, it is likley that the oven ignitor isn't working and needs to be replaced. To verify if this is the problem, when you turn on the oven to BAKE and set the temp at say, 350. Watch through the window, (or you can have the door open). Look at the bottom, back, center and see if you see a bright orange glow appearing under the bottom panel.

If you don't, that is why the oven won't lit the gas. There is an ignitor for both the broiler burner at the top and for the bake burner in the oven compartment.

It might be possible that your oven uses the same ignitor for both the broiler and bake burner tubes, so you could swap them if you wish to confirm that is the problem before you go and order/buy a new one.

Sometimes the ignitor burns out half way through but because it still lits/glows, people think it's OK, but it won't get hot enough to signal the gas valve to open and allow gas to ignite and get the oven cooking.
If you want to see a line drawing and a parts list showing the ignitor(s), go to searspartsdirect.com and enter in the model number of your oven and click on the links shown.

Hope this helps and best regards!

Localwonder gave a more comprehensive answer, but I wanted to share my recent related experience too:
Same model: MGR5750BDW
Oven was not heating up, or would sometimes and not others. Broiler worked fine. The nice thing is that the broiler igniter and the oven igniter are the same part. So I swapped them until I could get a replacement part.
Before I did anything, I turned off the gas!
To take out the broiler igniter: there's one screw right near the front of the oven that holds the burner assembly in place. Remove that, gently pull the assembly off the gas nozzle off to the left. Then where the wires from the igniter go into the back wall, remove the screw that holds the little door, remove that little door, and then gently pull the wires through until the connector comes through the opening. I also found you can go behind the stove, remove the back panel (which is easy) and see the igniter's connector.
The oven one: remove the floor of the oven by lifting it at the back, and then lift it out towards the back of the oven. Then you can see the igniter at the back of the floor of the oven. remove the two mounting screws, and then gently pull the wires until the connector comes through the insulation.
The bad igniter looked like it had burned down to bare metal in a big patch...not sure if that's the actual problem, but in any event, I installed the good igniter in the bottom (gently pushing the reconnected connector through the insulation, and feeding as much of the wires down in there as well), and the bad igniter in the broiler position (since that was the easiest one to access and replace, it'll be easy enough to replace when I get the parts). Tested, and everything worked great. And I could watch the bad igniter light up, and never light, confirming that it was the igniter itself that was the problem.
The best part, for this stove anyway, -- the ONLY tool needed was a #2 phillips screwdriver. Really. All told, maybe an hour of work, nothing intense. And free -- so if they both worked, it would have spared me ordering a part that didn't need to be replaced!

Usually when an oven won't bake, it's because the bake igniter is weak or burned out. The igniter is a small, round or rectangular device, that's about 1 inch by 4 to 8 inches. It's near the burner itself.

The burner is the tube-type device the gas flows through before it's ignited. It has many small holes on the sides to let the gas, when ignited, form a long, low flame. If the igniter is weak, if it glows red but doesn't get hot enough, or if it's burned out, the gas doesn't flow to the burner and the burner won't ignite. If this is the problem, you may need to replace either the igniter or the gas safety valve. Usually the igniter is to blame.

Other causes Other reasons that your oven may not bake are:

• The clock settings are incorrect (if you have timed baking or a self-cleaning oven).
  
  
• The thermostat is defective.
  
  
• The safety valve that prevents accidental gas flow is defective.
  
  
• The selector switch is defective.
  
  

Most likely a hot-surface ignitor has failed. If it doesn't consume enough current, the gas valve won't open. It's usually a fairly easy fix, once you gain access to the ignitor and have a new one to replace it with. Make sure you unplug the range...

Oven bake ignites usually have lifetime 5-7 years. If igniter glows but gas not came in - replace igniter. Same with broil igniter.

jdelvecchio5Does the igniter (glow bar) come on whenever the bake function is selected.?

If the glow bar does not come on the safety valve will not open - no bake burner. check the electrical harness first then Try changing the igniter (glow bar first) before changing the safety valve/regulator.

Very well could be. I'm assuming the bake burner is the problem, right? Does the igniter glow at all? If it is glowing, but the burner does not light, is it usually a symptom of an igniter that has become weak. If it does not draw enough current the gas valve will not open and the burner will not light. This is a safety feature to prevent free flowing gas without ignition. If the broil burner is functioning properly, then more than likely the gas valve and regulator are working fine. In most ranges both burners are fed from the same source. You could try swapping igniters between the broil and bake burners to prove the theory. Or, you could just replace the igniter all together. Current readings are as follows: Round shaped glow igniter: 2.7 to 3.2 amps Square shaped glow igniter: 3.2 to 3.7 amps If you can give me the exact model number off your range (usually located around the oven door or on the back of the range) I can give you the correct part number you will need. Most appliance repair stores carry the igniter. I hope this helps you.
