Vulcan 36lc oven won't ignite

The pilot fires up but the igniter does not shut off. When the igniter times out the flame dies. The PV silenoid has power, the MV does not. When I apply power from the PV (24v) to the MV the oven burner lights, but the igniter keeps firing.

HI,

Sorry to say this but there is no service or wirirng diagram available anywhere for your model.

The only solution to get the service manual for your model is to contact Vulcan and ask then to email you a copy of it.

Goodluck..

SOURCE: vulcan 148l oven burner will not light. pilot on.

Yes.

Over time, thermocouples erode in pilot flames and when they no longer reach the pilot light they need to be replaced. Check the thermocouple mountings as well: some ham-fisted amateurs try to bend the probe back into the pilot light and break the mountings. The pilot light jet will also need to be checked to ensure that it is clean and that the pilot is burning correctly.

Note that as with all gas appliances, repairs should only be carried out by qualified gas fitters who have the tools and knowledge to leave your appliance in a safe condition. In many countries it's a legal requirement. My reply is therefore given on an informational basis only as poor workmanship on gas appliances is directly attributable to many deaths every year.

You need to replace the thermocouple for both sides of the oven. That is the most common issue with pilot lights and gas burners. The safety shut off will engage when it does not sense any heat, ie: thermocouples.

Old wedgewood oven in home...very low pilot light in oven...how do I adjust it?


The oven pilot is usually located at the back of the oven; turn a screw on the pilot ignition unit to adjust the pilot flame height.

here is a link, pretty much all older ranges operate the same.

After oven reaches desired temperature, it has late ignition that turns off the pilot AND OVEN WILL NOT STAY ON.


Sounds like the pilot is mounted to far away from the burner. I have seen it happen before where the pilot has detached and the main burner will just keep pumping gas in until it hits the pilot flame and just flash flames and everything goes out.

Or it just could be a bad thermocouple that is going out all the time.

The fan is working bt the oven isnt getting hot


I assume you have already checked the gas supply by turning on a burner on top.

Do you smell gas when the oven first tries to light? If the flame sensor isn't picking up a fire on the oven burner within a few seconds after the igniter is supposed to start firing, it will shut off the gas valve. The first thing to check is the oven igniter. Can you hear it sparking (repeated snapping sound until main flame starts)? The sound may be drowned out by the fan, so hearing it would only verify that it's making sparks; not hearing it doesn't tell you anything unless you were able to hear it before the problem started. If you had a major spill in the oven recently, it's possible some residue made its way to the igniter or pilot flame tube and is gumming up the works.

The next items to check would be the oven gas valve and thermostat.

I have a Maytag gas over/stove, Model number MGR5755QDW. The broiler heats, but the oven does not. What are the possible causes and how do I troubleshoot?


If you are having problems with the oven, the first thing to do is figure out if you have a pilot light system or a glow bar system.
Problems with the pilot light system.....The flame has gone out, re-light the pilot. The pilot flame will not light - possible oven control is not sending gas for the pilot light. The pilot light works but no main burner ignition - possible pilot assembly is dirty and the pilot flame is too small, safety valve and thermocouple is faulty, the bulb from the safety valve is out of position and the pilot flame is not touching the thermocouple bulb. Some ranges use a standing pilot light ( small flame is on all the time ) while others use an spark ignition to light the pilot light flame and the pilot light flame heats up the thermocouple bulb to allow the main gas to flow through the oven burner.
The flame needs to heat the bulb up enough to tell it to open the gas valve. Several things can go wrong here that keep this from happening:
The pilot flame may not be hot enough, usually because the flame is yellow instead of pure blue or is too small. The cause for this is usually a dirty pilot assembly. The pilot assembly would either need to be cleaned or replaced.The thermocouple bulb may not be positioned properly in the flame. You can't heat the bulb properly if it's not in the pilot flame! The thermocouple bulb needs to be in the upper third of a pure blue pilot flame--that's the hottest part of the flame.
The thermocouple itself may be burned out. It happens. It's a internal part of the gas valve so, no, you can't just change the thermocouple bulb separate from the gas valve.
But when you turn on the oven or the thermostat calls for heat, the pilot flame gets bigger and jumps down so it can heat up the thermocouple bulb. This extra gas to increase the pilot flame size comes from the thermostat.
If the pilot flame jumps upwards or just gets bigger, but doesn't shoot down, then you need to replace the pilot assembly.If the pilot flame size does not increase or jump down when turning on the oven thermostat, then the problem is the thermostat not sending enough gas to the pilot assembly. It's also possible that the pilot gas supply tube has a hole in it somewhere.
One final point on the spark-assisted pilot ignition systems. The spark comes from the spark module--the same module that sends spark to your surface burners to light them up. If you're not getting a spark when you turn the oven on, then there are several possibilities:
There could be a problem with the switch in the thermostat. You can confirm this by doing a simple continuity test of the thermostat contacts. If you don't read zero ohms when you turn the switch on, replace the thermostat.The spark module could be bad. You'll need to measure the voltage at the oven terminals of the spark module when you turn on the oven. If you get 120v but no spark, it's probably a bad spark module. Replace it.
Could be a bad spark wire or broken electrode.
Problems with the glow bar system.....You may even see the orange "glow plug" (called a hot surface igniter) glowing orange and so assume that it's OK. Not necessarily!! You have to measure the current/amp drawn by the igniter and compare it to this repair sheet before you can say it's OK or not. The gas valve has a bi-metal that open when a certain amount of current flows through it to heat it up. The igniter is wired in series with the gas valve. As the igniter gets older or weaker, it's resistance increases to the point where not enough current is flowing to the gas valve bimetal to open it up. As a result, the gas valve never opens up. BTW, a common symptom of the early stages of this problem is erratic temperature control in the oven due to delayed firing of the bake burner while cooking.
The hot surface igniter will not come on - check igniter with a ohm meter, you should have continuity through the glow bar, the glow bar can also crack = new igniter time. The glow bar comes on but the main burner will not light - you should have an amp probe to check properly, but often this is a hot surface igniter problem. The hot surface igniter often looses it's ability to get hot enough to open the gas safety valve. The safety valve can fail, but most times it is just a bad hot surface igniter. The hot surface igniter can also quit part way through cooking , in other words the oven may cycle a couple of times and then it just sits there with the red glow from the igniter. See this service sheet for the proper way and amp readings for the hot surface igniter system. Hot surface igniters do weaken and will eventually generate less heat than they normally could. When this happens they can still allow marginally correct current to flow to the oven gas valve for it to open but not get quite hot enough to ignite the gas burner immediately. When this happens, gas released into the oven can sometimes build up to the point where when finally ignited, the amount of gas lit can cause a small explosion inside the oven or cause an odor of gas with out the oven working. Yes, your glow bar igniter can glow orange-red and still be bad!! How a common gas valve works -click here.

I have a Frigidaire gas range, model #FGF316BSA. When I attempt to operate the oven it won't light. The glow bar comes on but nothing happens after that.


Hi


Thanks for using FixYa. From what you have described it seems that possible oven control is not sending gas for the pilot light. The pilot light works but no main burner ignition - possible pilot assembly is dirty and the pilot flame is too small, safety valve and thermocouple is faulty, the bulb from the safety valve is out of position and the pilot flame is not touching the thermocouple bulb. Some ranges use a standing pilot light ( small flame is on all the time ) while others use an spark ignition to light the pilot light flame and the pilot light flame heats up the thermocouple bulb to allow the main gas to flow through the oven burner.


Please do accept the solution if the issue is resolved or else revert for further assistance.


Thanks

GE Spectra TrueTemp Oven Pilot is Out


REmove bottom panel from stove. shut gas off for at LEAST 5 min. Longer is better. Then placel open flame above gas nozzle, slowly turn to ignite posiiton. After it is lit, wait 30 seconds and turn to on positon.
If by chance this model doens't have a knob for this, then turn gas valve off for 5 min, let fumes evaporate, light flame, place over nozzle, turn gas on.replace bottom oven panel slowly.

GE STOVE MODEL JGBS15GE


Often times you will have problems with the gas thermostat and not necessarily with the safety valve. Once you have lit the pilot light, turn the oven knob to any temperature. The pilot light should get bigger in size of flame. If not, the thermostat that controls the oven must be replaced. If the pilot light does get bigger, but the stove does not ignite, it is the safety valve.
