What's wrong?
The recalled equipment in 2001-2005 Keystone Montana-Big Sky, Montana, and Everest recreational vehicles is the plug-in remote control receiver used with Dimplex Electraflame, Symphony, or Optiflame electric fireplaces, stoves, and fireplace inserts. The receiver sits between the wall power source and the fireplace control, and it listens for the handheld remote so the unit turns on or off without using the fireplace controls directly.
The defect is in that plug-in receiver, not the cabinetry around the fireplace. During use, the receiver can overheat instead of safely carrying and switching power for the fireplace. Once it overheats, the part is no longer doing its normal job as a controlled electrical switch.
There is no warning sign before failure. Owners should not rely on smell, sound, or a visible change at the fireplace to know whether the receiver is affected.
