What's wrong?
The affected equipment is the plug-in remote control receiver used with Dimplex Electraflame, Symphony, or Optiflame branded electric fireplaces, stoves, and fireplace inserts in 2009-2010 Monaco Coach Diplomat, Alumascape, Knight, and Ambassador vehicles. The receiver sits between the wall outlet and the fireplace unit. Its normal job is to receive the handheld remote signal and switch the electric fireplace on or off.
In this recall, the receiver is the weak point. During use, the plug-in receiver can overheat instead of handling the electrical load cleanly. That heat is concentrated at the receiver and the outlet area, so the problem is tied to the fireplace control hardware rather than the whole vehicle.
There is no warning sign before failure. Owners should treat the fireplace receiver as suspect even if the remote works, the fireplace turns on, and there is no odor, flicker, or visible damage.

- Tell Dimplex or your Monaco Coach service contact that your RV is tied to recall number 10V455.

What happens at the repair
Monaco Coach is working with Dimplex on the remedy for the electric fireplace remote-control receiver. The remedy listed for campaign 10V455 is a free replacement plug-in remote control kit from Dimplex, with the safety recall beginning in October 2011. Because the current remedy status is not listed as available in this input, confirm the repair path with a Monaco Coach dealer before planning service. Once the remedy is open for your VIN, the replacement kit is free under the recall. The source does not list a separate reimbursement plan, so this section does not add reimbursement instructions.
