Grill regulator activate with +2 burners or more
I have a "Backyard Grill™ Stainless Steel 4-Burner Gas Grill - BY14-101-001-02"and all last summer it grilled fine with no issues. So before May we decided to get the tank topped off and have a cookout.. Grill started up with nice high flames, but about 30-60 seconds later regulator safety toggles and gas flow is cut, causing my flame to die out slowly... serious bummer.
The grill does light when I only use one burners, but if any more are turned on the stay lit for a couple of seconds then it dies out...
Things I have tried/been instructed to do:
Reset Regulator - I have reset regulator multiple times. used different methods.
Replace regulator - I have tried three different regulators, different brands from hardware store...
Check for leaks - soapy water sprayed on propane tanks fittings, regulator,lines, manifold. no bubbles.
Clean burners - holes and debris cleaned out.
