Gas oven will not ignite

We recently installed a used commercial gas oven for baking donuts. We were told it was working when we bought it. It runs on regular 110 - 115 V and natural gas.

When we turn it on the fan runs and the oven lights work but the burners will not ignite. There is no click to signify that the igniters are working. And no lights on the panel either. There is only .4v on both sides of the thermostat.

I'm not sure if this unit has a pilot light or not.

When I turn the gas on and turn the power switch on, I can smell gas and the fan runs but nothing clicks or fires up.

Do I have to light this up manually the first time?
Why do I smell gas if the igniters are not working?
What if I did get this going and the pilot light ever went out, would the room fill up with gas? Should it not have some kind of safety device to prevent gas from flowing when there is no flame?

It sounds like somebody bypassed the flame sensor on the oven, no oven should ever release gas for more than a couple seconds if there is no ignition. This oven is very dangerous and should not be used until it is looked at by a professional.

How to Troubleshoot a Gas Range Oven That Won't Heat
By Kefa Olang, eHow Contributor
Although gas range oven may prove useful for cooking and baking, they may fail to ignite if they aren't properly maintained and set up. Lighting a gas range often involves simply turning a knob; however, blockages from food particles and debris caught in the burners, improper burner cap installation and gas supply are common problems that interfere with your gas range oven's performance. A few troubleshooting guidelines may solve these problems safely.

      Inspect the small vertical holes on the side of your burners for dirt, food and debris. The gas won't ignite if they are clogged. Scrape dirt, debris and food from the vertical holes using a pointy object such as a toothpick or paperclip.

    • 4
      Reinstall the burner caps properly. If they are tilted or wobbly, the gas may not ignite. Install the caps on the right burners. Some burners are smaller than others, so match the caps to the appropriate burners.

    • 5
      Move the burner knob to the "Lite" position and wait for the gas to ignite. If it ignites, rotate the knob to your desired setting. If it doesn't ignite, contact a qualified appliance technician.

I turn the oven to 350 degrees and it never gets hot.


First, I guess we need to define hot. If you mean hot enough to bake whatever it is you wanted to bake, then it's possible, if this is a unit that has a "timed bake" feature, that someone neglected to put the control back in manual mode, after having used the "timed bake". If this happened, then the oven will only heat to 160 - 180 degrees, and will maintain that temp. It's called a keep warm setting, which is designed to keep the food that was recently baked, warm, until someone can come get it out and served. Check this feature if you have it and see if it's in manual mode, if not change it and the oven should heat up to 350 and beyond.
If there is NO "timed bake" feature, and there's some heat, just not enough to get to a bake mode, then it's possible that the oven's ceramic glo igniter is cracked and not heating to the point that it allows the oven's safety gas valve to open for gas flow to the burner. If there's no heat at all, the problem could still be the igniter, but it could also be electronic control box feeding the igniter. These things must be checked by a tech with an ohmmeter, and possibly replaced.

Oven will not heat past 100 degrees. Circuit breaker is not tripped. All other parts of the oven work fine.


Hello there:
It won't bake or even heat up correctly or If your oven won't bake, check these: Bake igniter Other causes Bake igniter 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.

My kenmore gas oven won't heat. I turn to dial to temp i want can smell gas building up in oven and can see a glow in bottom of oven but will not ignite. Sometimes if I turn on a cooking eye I can then...


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
-- defective gas valve coils

Oven won't light.


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!

There is no gas going to my oven. Only the


hello, i can help you. first of all, if the broiler works then you must have gas coming into the stove. as far as getting to the gas line, it is in the rear of the stove. typically you have to pull out the stove to get to it. that said, here are some things to consider.

Not all gas ranges/ovens require electricity. If yours has a clock, electronic igniters, self-cleaning, or any other electrical features, the unit needs electricity to work properly. Check to see whether there's power getting to the range/oven. Does anything turn on--even a light? If not, check for a blown fuse or tripped circuit breaker.

It won't bake If your oven won't bake, check these:

Bake igniter

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.

It bakes poorly Here are two instances of when food "bakes poorly:"

  • When the item takes far too long to finish, you probably have a weak bake igniter. Often, you need to replace the igniter, but you may want to troubleshoot the oven's electrical system further to more precisely locate the defect.

  • When the temperature is consistent but too high or too low, the oven thermostat or sensor is either mis-calibrated or defective. If your oven uses an electronic temperature-regulating device, you may have an electric sensor in the oven instead of a mechanical thermostat. If the oven temperature is off by 30 to 40 degrees in this type of unit, you must replace the sensor.

    On many units with a mechanical thermostat, you can remove the thermostat knob and adjust the knob itself to more accurately represent the actual setting of the thermostat. If, when you remove the knob, there's a screw on the back of it with a small calibration plate, you can loosen the screw, adjust the plate, then tighten the screw again. If the knob isn't adjustable, and the oven temperature is off by more than 30 to 40 degrees, you need to replace the thermostat to solve the problem.

Maytag gas oven mgr5770abb Does not light when I try to use oven. Broiler works fine. When I try to turn on the oven, the broiler igniter does not glow. If the bottom igniter was bad, wouldn't the top one...


first I would check to see if you have power (120v) at the bake igniter..when you set in to bake...use a multmeter..(when you turn on the oven to bake only the bottom igniter will come )

good luck be safe

let me know if I can help
