NHTSA Complaint #11621634 — 2024 WINNEBAGO EKKO

The A/C on our 24E/24T EKKO stopped working today, October 13, on old Route 66 in Oklahoma. The ICM870-16A-BH5400 easy start circuit board was fried. A portion of the circuit board had melted and the brown wire was loose and the connector melted. The ICM cover fell loose when I removed the GE A/C cover. See the attached photos. The ICM870-16A-BH5400 is included in GE Kit GEASST-1. The BH5400 suffix is unique to the GE sourced easy start. This may not be important, but upon inspection, using ICM680 installation instructions on-line (see attached), I noticed that the red and white/blue wires from the ICM controller were switched on the run capacitor H and C terminals. I assumed that the wire colors shown on the installation wiring diagrams are the same for all ICM680 controllers and all applications. If the installations are the same for all ICM680 controllers, then the red wire from the ICM controller is to be connected to the run capacitor on the C post. On our unit, the red wire is connected to the run capacitor H post and the white wire is connected to the C capacitor post. The wiring diagram on the blackened ICM cover, shows the red wire attached to the capacitor H post (also attached to the motor S post) and the white wire to the C post. As a reference, I am attaching the ICM680 installation instruction wiring diagrams found on web as well as written instructions. I could NOT find a wiring diagram like what is shown on our blackened ICM cover with the red wire attached to the H post. The QR Code for online installations on our blackened ICM680 cover resulted in a 404 Not Found notice. I called ICM technical service but could not leave a message as the voice mailbox was full. No serial number could be found on the ICM box. See the attached photos of the fried controller and the ISM wires attached to the run capacitor with the red and white wires reversed from what is shown on the wiring diagrams.
