KEYSTONE issued a recall on the CAMBRIDGE model

On certain fifth wheel trailers, the dimmer switch may have been wired with reverse polarity. This will cause the lights on the switched circuit to either not function at all or the dimmer switch will not dim or shut off the lights. The switch may become very hot and melt the plastic housing of the switch, possibly resulting in a fire. Correction: Dealers will inspect and verify the switch is wired correctly, the switch will be tested to determine if it turns the lights on, dims the lights and shuts them off. If the switch does not pass this function test, it will need to be replaced and wired accordingly.
