Peter S Chicago , IL January 20, 2026 E09 error code Quick search online revealed I had a bad heat pump, so I ordered and the problem is resolved. Videos online showed how to do the swap. I found it pretty easy - hardest part was disconnecting the wire harnesses as I didn't want to damage the wires, just take your time. Also replaced our cracked handle while I was at it.
