Is the gas valve on? gas line cutoff set to allow gas to flow through. there should be a list on the control panel to tell you what 4 flashes means its probably no flame sensed. the board may not be sending power to the gas valve or the gas valve could be stuck.

Need more info. Are you saying that when tstat calls for heat then it short cycles. But if you turn it off then back on it runs ok?

Yes, there is a flame sensor that will tell the gas valve to open, thus igniting the burners. When you say the fan is running is it the blower fan or the little exhaust fan connected to the vent. Because the blower fan should not come on when the burner is not firing. I think you need a new limit switch that or your thermostat is being being unreliable. Try by-passing the thermostat by jumping the red to white wires on it. They are only 24 volts so you need not to worry about being shocked (you may feel a slight tingle if the conditions are right) you do, however need to be careful not to touch any of the wires to anything else as it may blow out your transformer or the fuse protecting it, to see if it changes the problem. When the ignitor is clicking can you see spark jumping from the pilot to the probe? I will need more info to be more helpful.

SOURCE: Turn Thermostat to call for

That particular intermittent pilot gas valve uses one of three ignition control modules; S86F, S8600F, and S8610. Check the pilot assembly and look at the flame, could be a weak flame, dirty or clogged, if its not lit or weak, you’ll hear a constant buzzing or “sparking” sound, this will lock-out the gas valve. If you hear nothing at all, start with cleaning or replacing the pilot assembly, then check the ignition control module.

Hope this helps

Try cleaning the flame sensor. It is located right besides the last burner. Looks like a thick piece of wire. Take steel wool and gently remove the carbon that has built up. Should only take 4 or 5 strokes. Let me know how it goes after that. ken

My husbad had sent out an email of our problem that we are having with our range. I am not seeing that there was a response. Is it possible for someone to assist us? I turn on my oven but it does not heat...


Hello Kim....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 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. That said, if you want to see excellent diagrams of all of the parts of your stove, go to searspartsdirect.com Enter the model number and these diagrams will appear for your use. You can also order parts from that site, although your local appliance parts store may be less expensive. Joe Thanks for choosing Fixya!

Gas valve clicks but does not light


Hello
The click is either the gas valve opening or the ignitor trying to ignite.

From what you decribe,im going to say you have a bad ignitor.

If the gas valve is indeed opening,then you need igniton to light the gas,
which leads me to say bad ignitor.

Hope this helps.

We have a 6 burner, nat gas cooktop....all unit light but the igniter clicking will not stop...unplugged it . question: all mechanics are closed is this safe gaswise?


What happens in this style ignition system is that the thermostat or electronic control switches power to the oven ignitor and gas valve circuit which are connected in series (one after the other). As power flows through the ignitor it heats and draws current (measured in amperage). Once the oven ignitor draws a specific amount of current the oven valve opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it. Power must continually flow through the ignitor and oven gas valve for gas to be released into the oven burner to create a flame. Once the set temperature is achieved the control stops all power to the ignition circuit which causes the ignitor to dim and the oven gas valve to close, stopping any burner flame. Cycling on and off continues to maintain the specific temperature the control is set for.

Turn on green light flashes


Count the flashes before a pause. A steady on is bad ground or loose igniter. 2 flashes is either low gas pressure, bad flame sensor, gas valve wires loose or bad ignitor. 3 flashes is a bad pressure switch, or blocked vent. 4 flashes is a bad roll-out switch or open contact. 5 flashes is bad wiring to gas valve or flame sensor, 6 flashes is either a bad control board or bad thermostat.

Dryer start up fine then the gas turns off as ignitor continues


Hi Jim. Perhaps this will help you.

The burner assembly consists of the gas valve, the igniter and sensor, and the thermostats. The gas supplied to the appliance is turned on and off by the gas valve, as follows:


  • First--when you close the dryer door, set the timer, and press or turn the Start button--the motor starts. When it reaches full speed (in about a second) a switch on the motor turns on, which allows the electricity to flow through a simple thermostat to one side of the gas valve.

  • The gas valve then sends power to the igniter, which glows bright orange.

  • As heat and light from the igniter warm up a sensor that's right next to the igniter, the sensor circuit opens, then supplies power to the other side of the gas valve. This completes the circuit and opens the valve.

  • Once the valve opens, the gas rushes out and the igniter ignites it. As the gas burns, it keeps the sensor warm, which keeps the gas flowing.

  • When the dryer reaches the pre-set drying temperature, a simple thermostat turns off the flow of electricity to the gas valve and therefore turns off the gas.

  • When the temperature in the dryer falls about 20 to 30 degrees, the thermostat again allows the electricity to flow through to the gas valve, and the cycle starts over.

If you selected the Automatic setting, the cycle continues until the clothes are dry, then the timer advances and turns the dryer off.

If you selected a timed setting, the cycle continues until the time has expired, then the timer turns off the dryer

Hot Surface ('Glow Bar') Ignition System glow-amin.60x20.gif (most common)
This is the most popular system currently in use and is comprised of a control mechanism (whether thermostat or electronic control), the oven ignitor and an oven gas valve. What happens in this style control system is that the thermostat or electronic control supplies power to the oven ignitor and gas valve which are connected in series (one after the other). As power flows through the ignitor it heats and allows a specific amount of current to flow to the oven valve which is in the same circuit. If the oven valve senses the proper current flow, it opens to allow gas to flow to the oven burner where the glowing hot ignitor (glow bar) ignites it.

Thermostat seems ok, but gas won't flow from oven burner.


Hi, Even tho the ignitor is glowing, it is getting weak and will need replaced. The ignitor is not pulling enough amps to open the gas valve.
This is very common problem with the gas ovens.
If I can assist you further, please let me know.

Oven won't light, even with ignitor getting red


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.

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.
