Hello
As the topic. Initially, the furnace was reset (reset button for 5 seconds) and returned to normal operation. Now, unfortunately, it comes to P4 during startup and goes into error F0.
The service technician, without touching the furnace, stated that the mainboard needs to be replaced although in the manual they write about loose connections, etc.
What do you think about this case ??
