Everything working great before changing the filter. What is rc or rhythm on thermostate. My rc not showing power

Nest 3.0
Expert:  airheatman replied 1 year ago.

For some reason we are not getting power from air handler to thermostat.Is there a float switch in main drian with 2 wires connected that may have gotten bumped or control wiring bumped that would have lost connection?

Customer: replied 1 year ago.
I sent you two pics
Customer: replied 1 year ago.
Customer: replied 1 year ago.
I don't see switch to the drain
Expert:  airheatman replied 1 year ago.

With filter in bottom of unit, there is nothing replacing filter should have done.Lets turn power off to air handler and back on and see if thermostat will reset.

Expert:  airheatman replied 1 year ago.

OK hang on, I see wires to your filter now.

Customer: replied 1 year ago.
Ok here is nest setup
Expert:  airheatman replied 1 year ago.

Do you have a volt meter?

Customer: replied 1 year ago.
Unfortunately I dont
Expert:  airheatman replied 1 year ago.

Lets look at that fuse.You will have to remove top panel to see it

Customer: replied 1 year ago.
That might be tough for us to do. If it was a fuse won't it trip our breaker box
Expert:  airheatman replied 1 year ago.

No this is a small 5 amp auto type fuse in low voltage circuit http://i.imgur.com/kYe4Epz.png

Expert:  airheatman replied 1 year ago.

Plugs onto furnace board

Customer: replied 1 year ago.
Is it easy to replace if that is the problem or service tech has to donot?
Customer: replied 1 year ago.
Do it
Expert:  airheatman replied 1 year ago.

If it is fuse, it can just be unplugged and a new one plugged in

Customer: replied 1 year ago.
Where do find fuse like local hardware store
Expert:  airheatman replied 1 year ago.

Or local auto parts

Customer: replied 1 year ago.
I will try that. Due to disability I can't remove that panel.
Expert:  airheatman replied 1 year ago.

I understand. For some reason we have lost the low voltage to the thermostat.

Customer: replied 1 year ago.
Is this expensive fix
Expert:  airheatman replied 1 year ago.

Most likely not. If we find indeed it is a fuse, the fuse is less than a buck, If we find it to be a transformer or something, probably 30 bucks or so plus labor.
