A friend has a oven that has been coming on with a bang. I've cycled it on and off cold and hot no problems when I was there. Pulled the botten pan out (it is quite worped from heat and dosn't fit that...
a lot of iffy things could be happening here..
verify proper amperage draw through the ignitor.. i believe thats a 3.2-3.5 amp system but check the label thats on the gas valve, it will have the ratings listed on there for sure. make sure amperage draw is in the middle of the range as some gas valves are less tolerant of low amperage draw than others.
it almost sounds like your amperage load may be on the low side, just enough to open the valve regularly but not open fully..
its on its way out if so..
the popping could be the gas coming into the oven slowly enough to NOT blow directly across the ignitor properly, (igniting it instantly if it were) and allowing it to pool in the enclosure some because of the low amperage draw through the ignitor, eventually firing with a bang..
yes the regulator vent could be plugged, but another thing is if you are on bottled gas/lp/propane for your source of fuel the regulator at the tank could be faulty also, causing the pulsing flame..
hope this helps,
best of luck,
