Have a pavier commercial oven, reads open imp on the led, lights for 3 sec then no flame?

switch the dial to the indicator which shows the top grill,usually this is a black line with a squiggle under it.

I had to replace my igniter to get mine to work. I did it myself for $65.00 Mine the gas just would not stay on to heat up.

You need at least 24 volts for the gas valve to open

After burner on did you hear any spark ignitor if that your flame sensor is dirty or need to replace....good luck

What is the model number?

Chances are it is the igniter go to Searspartsdirect.com

Instructions

1. Access the burners inside your oven by removing the access panel in the front of the oven or by opening the broiling drawer, depending on your particular model.
   
2. Determine if the pilot itself is lit, since some ovens have a small flame on the pilot at all times that then grows and extends to the burner when the oven is turned on. The lack of a pilot flame indicates the oven thermostat is malfunctioning or there is a problem with the gas hose. Check the pilot itself to see if it is clogged with debris or grease that could be preventing the flame from staying lit.
   
3. Determine if the pilot flame will grow if it is lit by turning on the thermostat. If the pilot flame doesn't extend, the thermostat itself likely needs replacement. If the flame is extending but the gas valve is not opening, the safety valve could be dirty or defective. The flame should be blue in color. A yellow flame indicates the pilot is dirty and is not burning hot enough to get the main burner to ignite.
   
4. Light the burner on the top of the oven with a match if the igniter doesn't appear to be effective. If it lights manually but will not light automatically, the igniter is likely faulty. Do not do this if there is a heavy smell of gas in the kitchen, since there could be a risk of a fire. In that circumstance, turn the oven off, ventilate the room and call a technician.
   
5. Listen for any sounds of gas hissing or a clicking sound indicating the oven is trying to turn on. If there is no response from the oven at all, the gas may not be functioning properly and will need to be examined by a technician for safety purposes
   

Turn off the gas supply to the range. Remove the oven racks,oven base pan,flame spreader.

Place a clamp on amp meter on one wire of the ignitor and turn the oven on to BAKE. When the ignitor glows it should read more than 3 amps. If it reads 3 amps or less replace the ignitor.

bloody hell that is so scarey i have the same problem and its round about the same time yours went funny if you have a solution can you let me know as im looking for the answer myself [email protected]

At the risk of stating the obvious, you have pushed down the igniter switch long enough for the thermo couple to pick up the naked flame and therefore hold the gas valve in the open position? Usual only about 10 secs but can be up to 30....
