LED indicator lights on the kitchen range knobs over heated and caught on fire. I was filling the pantry in preperation for an upcoming trip. When I turned on the pantry light to the motion sensing position there was a slight momentary buzzing sound. I turned the switch off but then noticed that the LED light on the range knob was smoldering next to me. The LED then caught on fire and I extingushed it with a kitchen rag. I disconnected the trailer from the household power connection and turned off the battery disconnect switch. A few hours later when my spouse arrived home I connected the shore power and the battery disconnect while she observed the unit. We observed that the lights on the other range knobs were illuminated even though the switch was in the off position. The pantry light was on but very dim. Within a minute or two a second LED ring on a different knob smoldered and popped. I immediately disconnected all power and than contacted the manufacturers customer service department when they opened the following day. They are supposed to be sending a replacement range to a local service shop for replacement. We are still waiting for the new range to arrive. The manufacturer has stated that they want the defective range returned to them for inspection. We have been unable to turn on any power to the trailer due to fear of another fire.
