No heat, no ac, no fan, no noise
It's not working at all. We've tried readying the breakers, waiting, and it's too cold to do anything else. We've switched the thermostat on and off, onto heat and air, nothing.
No clicking, no whirring, nothing. I don't know what to do in this situation. The model is 30VDX10-HP. It came with the house, but I don't know how old it is.
