1) check for electric power. blown fuses.
2) check that t'sat is calling for cold.
3)check that fan can turn on both condenser and air unit. filters ect.
4) look for anything that is out of the ordinary.
5) hook up pressure gauges just to see if there is any refrigerate .
1thing that causes that is low Freon, also poor air flow from dirty coils.
the new filter doesn't have anything to do with your problem.
the problem was happening prior to the filter change cause the old filter was soaked by the melting evaporator coil ice.
shut the unit down until things thaw out, then try to run just the blower without heat or A/C. I suspect your blower system is bad or going bad. notice the speed of the blower in both heat and A/C mode as each setting will run at different speeds. could be your cooling winding is bad but heat windings are Ok.
let us know what you find.
Because you said it was soaked.
Panels on or off as long as you can get an idea of the fan speed.
I left it running for 8 days, set on 72 degree "Cool" and the fan set on "Auto" with no filter in.
When I got here, the house was 72 degrees, but not sure it was running because that's about the same temperature it is outside.
The ice seems to have melted from the evaporator coils, however.
I turned the fan to "On" and I think it hums, but doesn't turn on. This is what it sounds like.

Bingo!! That's what I was referring to. Either the motor or capacitor or both are bad as long as your getting proper voltage to the windings. Do you have any meters to test these components?
No. What should I buy?
And I still find it interesting that this problem started the same time I changed the filter. Guess it's just a coincidence.

well, it hums because something is wrong.
could be not getting enough voltage.
that is why i asked about a meter.
you have a couple of choices here.
buy a meter and find the faulty component(s) or just by new until the problem goes away.
your first and cheapest option is to replace the capacitor. if you don't have a meter to read it then maybe the supply house can test it for you.
otherwise, gamble $20, replace it and see what happens.
if capacitor is good and voltage is good then it will be the blower motor itself that is bad.
