Gas Oven Won’t Heat – How to Repair (Part 1 of 2), Troubleshoot
All right everyone, welcome to Tomahawk DIY. Today we’ve got a gas oven that will not warm, so we’re going to do
a little troubleshooting and learn how to fix what turns out to be an ignitor problem.
So first I’m checking it. I turn it on, it turns out
it will not actually heat inside. Now, in trying to figure out where the
problem is, check the gas burner at the front and that lights up, so you know there’s gas to the unit.
We’ve also checked the broiler to see if the broiler turns on. If we watch on here, it will actually ignite. If you look in the back, you’ll see an ignitor start warming and
then once that reaches the correct temperature we should see a flame come. So we know there’s gas to the unit. All right, turn off the gas. We’ll chek out underneath the oven. You can pull out this drawer or there might be a panel across
the front that you have to get out to look back at the gas valve. Okay, under the gas oven here we’ve got the
drawer out or you may have a panel. Under the oven, let’s take a look at
what we’ve got, you have a gas line coming in and you have a, I think this is the regulator. You’ve got one line in the back that runs up to the gas on top of the stove on the stovetop. You have this controller here that has a couple of gas lines, one that runs up here to the broiler and one that runs right here to warm your oven. The fact that broiler worked lets me know that gas is going through here. The fact that the oven isn’t heating
lets me know that gas isn’t going here. So we’ve got a few wires. These go up to the elements that heat those electrical elements that will heat up until the gas is released and it warms the oven. You can recognize which
wires go to those. They’ll be, if you feel them, they’re typically white and they’re wrapped with it’s like a braided,
flame resistant type material. In this case, these are a couple of those ignitor wires. Let’s take a look inside the oven. All right, if we open up the oven,
I’ve removed the racks already. And we want to get at the burner. In this particular GE oven. The burner is under the panel here. At the back there’s a couple of screws. I’ve already loosened them,
but there’s two screws at the back and along the front there is a lip or a ledge that helps hold this in. So, if we remove the screws then this whole panel can lift up and it’ll slide out like so and it call be pulled out. Once this is out of the oven, let’s see what we’ve got in here. Turn on the oven light, give us a
little light to see. Here is the ignitor electrode and here’s the
gas burner. So we’re going to go back up and turn on the oven
and see what happens.Turn it on to bake, should be starting, and we should see this ignitor begin to glow orange. From that, we see that the problem
is with that ignitor electrode. The next step is to check the
wires are secure and aren’t loose or anything, and provided that’s the case
then the next step is to remove the ignitor and replace it with a new one. Don’t forget to turn off the oven after you’ve tried to start it up.
Now, if your oven won’t heat at all and the burners on the top of the oven, if it doesn’t turn on here at the burners and you seem to have no gas
nothing that would heat on your oven, then your problem may be back on this regulator where there’s a safety switch. In this particular oven,
the switch is here on the side of the regulator.
It’s similar for other ovens and it can be turned down. If that switch is turned down, you’ll find that nothing in the oven will turn on.
If your elements will glow, both the element up on the broiler up here if that glows, and the element down at the bottom for the oven,
if both of those will glow when you turn on the oven, but will not,
doesn’t actually start the gas then your problem is likely this switch down below. Sometimes this switch, if you’ve been moving or
handling them, it may have gotten bumped or jiggled. In this case we’ll turn that on and that will allow the gas to flow again so the oven can start. You want to find which wires go to the element that you’re trying to fix.
It may be helpful to have someone with you who can jiggle wires and check to see inside the oven that they moved. All right, so let’s look at how
to disconnect this ignitor. If you look back behind, it’s a little tough to see in the video here, but there’s a couple of bolts right under the ignitor that you have to to get out. Disconnect and always remove to the down below, once you’ve identified which wires belong to the ignitor, you can disconnect them. In this case it’s this plug here and this plug right here. This is the back one. With that, we’ve got them removed and we can pull these up into the oven. Reach back and see if you can pull these up. We have our two leads. Now, we’ll get these bolts that are under unscrewed. ***SEE PART 2 VIDEO ON HOW TO UNSCREW*** Once you’ve got the bolts removed,
on this particular model it was a little tricky to get at them, but with some care and the right socket, I was able
to get the bolts out. You can take your ignitor and get a replacement.
You may have to go to an appliance store or pick up an appliance part online.
**Amazon Link in Description*** They may have some generic models
that you can use or you may be able to track down the exact replacement using your oven part number. You may also be able to use an Ohm Meter to check the leads, and check for proper connection.
However, given the fact that this unit wasn’t heating at all, that suggests the problem is with the
ignitor itself. Once you get a new part, replace it, reassemble everything, and when you first plug it in check
to make sure it actually is heating before you do all the reassembly to confirm that the problem truly was this ignitor. All right, so you’ve got a new connector here. You’ll find the leads don’t have wires, don’t have plugs on them. You need to take your old ones off. You can simply clip them and then once you’ve clipped them, you can use your wire strippers to
remove the shielding from the old leads, and use your wire nuts to tie the new ignitor wires to the old leads, and you’ll be good to go. Reinstall your ignitor and you
can have your oven up and running.
