My oven is not turning on and it is a gas stove

To turn on the oven on your Defy Thermo Fan gas stove, follow these steps:

1. Make sure that the oven is properly connected to a gas supply and that the gas valve is turned on.
2. Turn the oven control knob to the desired temperature setting.
3. Press the oven ignition button to ignite the gas. You may need to hold the button down for a few seconds until the gas ignites.
4. If the gas does not ignite, check the ignition system and make sure that it is functioning properly. You may need to consult the stove's manual or contact a professional for further assistance.
5. Once the oven is ignited, it should begin heating up to the desired temperature.

Keep in mind that it may take a few minutes for the oven to reach the desired temperature, depending on the setting you have chosen. You can use the oven control knob to adjust the temperature as needed.
If you are having trouble turning on the oven on your Defy Thermo Fan gas stove or if you have any other questions, you may want to consult the stove's manual or contact Defy customer support for further assistance.

There must be a method of lighting the gas, usually with a piezo electric igniter or battery/mains powered. Try pressing on the oven gas tap.

normal operation is to push the oven knob in and turn
pushing in sets the igniter off and turning opens the gas flow to ignite
always light an oven with the oven door open
stop s an explosion if there is a problem
down load an operators manual bu going google and typing in --- user manual for ( make and model ) gas stove --- find a pdf version and download it

The hum may be a b ad regulator in the stove. Pull stove out and see if regulator is humming. It's where the gas line connects to stove.
Maybe the power was interupted to the stove which may have reset power to control board.

If you have a pilotless model it is very likely that your oven igniter is bad. This is fairly easy to replace. A contunuity check will show if the igniter is bad.

You didn't say whether you have a gas or electric oven, or oven & stove. I'll assume you have a stove, just to cover all bases.

First, you should shut down the oven: a gas stove will have a valve on the gas line behind the stove. The valve will either have a red handle or a flat stem that usually has a hole in it. Turn either valve 1/4 turn to shut off gas, use a wrench on the flat stem. An electric stove should be shut off by flipping off the double circuit breaker for it in your electric panel. Do not unplug an electric stove when it is on; this can damage the plug &/or electrocute you.

Most likely the inside of the knob has stripped out. Look at the knob for a hole that has a setscrew in it: a small allen wrench or screwdriver will loosen the setscrew, most knobs don't have them and will pull off. Be careful to use even pressure on two sides of the knob; if you can't pull it off, use two butter knives or flat screw drivers to pry it up enough to get a grip on it.

Look at the center stem on the back of the knob, it will likely be cracked or stripped. Some stems have a D-shaped metal insert that strips out inside the plastic stem. If you have one, pull off a burner knob and compare the stems in the back, if they are the same size, put the burner knob on the shaft for the oven control, and use that knob to turn the oven control off.

If the burner knob won't fit, use your fingers or a pair of pliers (gently) to turn off the oven control shaft. If the shaft stops normally, you can turn the stove back on using either the gas valve or the circuit breaker. If you have a gas stove that doesn't have electric ignition (a clicking noise when you turn on a burner) you may need to re-light the pilots for the burners. Lift the covers off the burners to re-light the pilots.

If you have succeeded in turning off the oven, you need a new knob -- you can get one at an appliance parts store or maybe a hardware store. If the oven control did not turn off normally, I would leave the oven/stove turned off: the control itself will need to be replaced by a qualified repair person.

This is more than likely the igniter to be sure you will need to do an amp draw on the igniter. To do this watch the video on troubleshooting a gas oven at www.appliancehelponline.com/servicemanual.html

the gas flow regulator for the oven is bad and needs replaced.

Replace the oven glow bar ignitor.

you most likely have a bad oven ignitor...if you see an orange glow under the oven panel that is your ignitor trying to come on....but if it is weak it will not open the gas valve.....acess the ignitor and replace it
