I have a Bompani BO 693 ZD/N and several of the burners don't stay lit. It may be the temp sensors. Where can I find replacement parts?

Sounds like a bad sensor not seeing the fl?me ( or temping it). Maybe it got bumped but if not you'll need a replacement to be safe.

simple flame sensors at fault eg thermocouples replace bad sensors and dsi box (direct spark ignition )

Strange to hear about a pilot-flame. Is it an old oven? Commercial unit? Look for a small valve at the end of the pilot gas-line and see if it is shut off. If it's on, okay. But, is gas getting there being blocked elsewhere? There may be a flame safety-switch, a sensor by the pilot, or some other thing that has a release button for lighting the pilot. You hold it in until the sensor heats up, and then it will stay lit. After that, there may be a re-set button to get gas to the main burner element. Basically, you have to trace lines back until you find the hindrance. CAUTION:With all gas appliances, you have severe danger of causing an explosion, and untimely death, or injury, so if you have any doubts, get a qualified guy on it! (It takes a while to grow a beard back, too.)

Hello,

While your holding in the knob after lighting the pilot,their is a thermocoupler that is heating up and will hold automatically what your pushing in, that thermocoupler is defective

The sensor on the burner is not sensing the flame. It could be the sensor itself or its' controller. You need to call for service.

you thermocouple is weak or flame sensor not in good location

are we talking about the oven.if so and the ignitor lite's up,and look's as strong as it was,than you my have a BAD SAFTY VALVE.

I just solved this problem with my GE gas range. I waited forever for the oven to warm up. The igniter would glow, light the burner and burn for a minute or so and go out. It would repeat this process till oven reached operating temp, which took forever. Problem is in the igniter. It may be glowing, but it is not letting the gas valve stay open, because it is not hot enough to create resistance in it to keep gas valve open. I had replaced the thermostat thinking it was the problem. The good part about it was I could take it back because my buddy works at supply house. Once the igniter was replaced, the oven fired up and stayed lit till operating temp was reached. It will also hold the oven temp much better. Oh yea, the igniter will stay glowing while the burner is on. Hope this helps.

hi Clogged burners are a very common problem with gas ranges because foods spilled on the burners block the gas ports and prevent ignition. On some gas ranges you can remove the top ring of the burner to expose the ports. Here's how to clean a burner:
Step 1: Turn off the power supply, both gas and electric, to the range. Then remove the burner.
Step 2: Soak the burner in a solution of mild household detergent and water. Clean it with a soft cloth.
Step 3: Clear the gas ports with a pin or needle, rinse the burner, and let it dry. Caution: Do not use a toothpick or matchstick to clean the gas ports. If the tip of the wood gets stuck in the burner ports, it could cause a serious blockage.
Step 4: When the burner is completely dry, replace it, and turn on the power and the gas supply.
thank u.................

this is a common indication that the ignition module is probably going bad or the flame sensor is not sensing the flame on the burners. There are other, more technical issues possible but this is usually the most common. The "not restart" , if referring to the burners, is an indication that the ignition module has "locked out" the system, usually after 3 failures of attempts to light the burners.
