The problem
VEHICLE DESCRIPTION: TRAVEL TRAILERS. THE SIMULTANEOUS USE OF THE MICROWAVE OVEN AND THE COOKTOP PRODUCES NEGATIVE PRESSURE THAT CAUSES THE FLAMES ON THE COOKTOP TO REVERSE. THIS COULD RESULT IN DAMAGE TO THE BURNER HEAD, POSSIBLY RESULTING IN EXTINGUISHING THE FLAME. IF THE FLAME IS EXTINGUISHED, LIQUID PROPANE (LP) GAS COULD LEAK INTO THE TRAILER.
Risk
THE PRESENCE OF LP GAS IN THE TRAILER COULD RESULT IN ASPHYXIATION OF PERSONS PRESENT IN THE TRAILER OR POSSIBLY AN EXPLOSION IN THE EVENT THAT THE LP GAS IS IGNITED BY A SPARK.
What owners should do
DEALERS WILL INSTALL A DROP-IN BURNER BOX KIT WHICH WILL ELIMINATE THE NEGATIVE PRESSURE WHEN THE MICROWAVE OVEN AND THE COOKTOP ARE USED SIMULTANEOUSLY.
