A 36" 4 burner range,

SOURCE: gas range top burners too hot

Get the installation manual for your range, and find the part on adjusting the low heat for the burners. On my Whirlpool, I found there is an adjustment screw inside the control knob shaft of each burner. The manual says turn the burner on low, remove the knob, then turn this screw until the flames are 1/4" high. Super-easy, it took me 5 minutes to do. I am sure all ranges have similar adjustments, might be in different locations - check the manual.

If it were the gas regulator, existing flames would go down as more burners are turned on.

There are set screws on the pilot fittings that come out of the manifold, you could try turning those Counter-clockwise to turn the pilots up. (Don't loosen them all the way, they will fall out!) If that doesn't work chances are the pilot stems will have to be replaced to get a higher pilot flame.

I think it sounds like one of two problems either the wrong orifaces were installed in the gas valves for the conversion or the pressure on the output side of the gas valve was not set correctly.

Now if you go to page 8 you will find where it goes part # 53 thru 61

Hi There,
While the stove is unplugged remove the bad burner from the stove and set the bad burner's control knob to the "OFF" position. Now plug the stove back in. If there is a problem it should trigger the breaker and shut off the stove. If you are not comfortable doing this you might want to ask someone.
The explosion was due to a shorted burner element and once it is removed there shouldn't be any more problems. I hope this was helpful and I hope you get your stove going again.
