Hey there. I'm seeking help troubleshooting my Lennox Healthy Climate HRV. It stopped working a few days ago and is showing some strange symptoms. Both the main on/off control as well as the individual wall timers show the various leds blinking in very erratic/random patterns. I will try and attach a video link.
The controls no longer turn the unit on and it no longer starts when the furnace calls for heat. I've power cycled it to no avail. It runs through its start up checks and that's it.
I'm handy with a multimeter etc, is there troubleshooting I can do?
Thanks in advance.
Tony
