Customer Question

I own a Wolf R366 gas range. The igniter module needs to be replaced (when the gas oven is turned on it is taking longer and longer for the gas to ignite -- now almost 1.5 minutes). Can you please tell me how to install a new Wolf R366 oven igniter? Or point me to where I can obtain a service manual? thank you.

Your problem is not necessarily with the ignition module. It's function is to provide the spark to light the burner, and yours is already attempting to do that. The more likely problem is the strength of the spark at the burner. Let me do some research on your model, and I'll post back to you.

OK, please let me know if you need additional information.

I'm not finding anything using the r366 model number, but I can probably work you through to the solution without it. Will you tell me what type of appliance you have? It it a cooktop, a range, or some other configuration?
Customer: replied 7 years ago.
It is a Wolf 36", 6 burner, gas range, converted to run on propane and high altitude. Here is the Wolf web site:

They show it as a model R366.

Please let me know if you have any questions.

thank you.

OK. Thank you. A couple of questions, if you don't mind. Are you having this delayed ignition problem with the cook top burners and the oven? What is the elevation at your location?
Customer: replied 7 years ago.
No problem with the cook top burners; only the oven, and only the bottom heating (the broiler (which has a separate igniter located on the ceiling of the oven) is working fine).. We are at 5800 elevation. The oven was installed in the summer of 2003. We started noticing the delayed "ignition" in the oven about 3 weeks ago. When the oven is turned on and open the oven door and look down in the crack at the bottom of the door, behind the stainless "kick panel" (located below the oven door) I see something glowing. When I turn the oven on the glowing starts about 10 seconds after I turn the knob on and it between 60 and 90 seconds before we hear the "whoosh" of the gas igniting.

I've seen this quite often with Wolf and Viking ranges. All most every time it's the ignitor. If it takes longer than 30 seconds after the ignitor hit its peak brightness to ignite its definitely a bad ignitor. my guess is its taking twice ass long to bake and even more difficult to maintain temperatures?
Customer: replied 7 years ago.
I have an oven thermometer (the type that sits on the shelf inside the oven). I will turn the oven on to a specific temperature and check to see how it compares with the stand alone thermometer.

How difficult is it to change the oven ignitor?

I was posting back to you, when Appliance Guy offered an answer, so I'll retype the post.

He's correct in saying that the glow coil could be causing the problem, but there's a couple of things that should be checked before you buy one, as they don't come cheap.

First, check to make sure the burner orifice is not restricting the gas flow. It could be partially clogged with grease. It's not all that easy to remove the burner, because there's a very limited space to work, but it's worth it if it saves buying a new glow coil. Tip: If you have trouble removing the burner, look at the back end of it to see if the shipping tie down wire is still there.

Second, try to wiggle the coil to see if the hold down screws have rusted at the floor pan and come loose. It does'nt take much movement to interfere with the light off time.

If these two inspections check out OK, it's time to buy a new glow coil. I'll post back with a part number and a price.

I turned the oven on and set the temperature to 300. It took 1 minute 35 seconds for the gas "whoosh" to occur. Two hours later I checked two thermostats sitting on the shelf in the middle of the oven about 1/4 to 1/3 off the bottom. One read 300 and the other 325.

I will have to wait until the oven cools off before removing the bottom oven plate to visually inspect the ignitor and hold down screws per your suggestion.

thank you.

The fact that the glow coil lights the burner at all is proof that it's getting hot enough, and does'nt need to be replaced. The burner and the glow coil are too far apart to get the proper ignition. The whoosh you hear is what we call 'delayed ignition'. Either the coil is loose or the burner is'nt in the proper position.
