AC & thermostat not working
Last night the main power switch to the furnace shorted out, fixed it this morning but still no AC andthe thermostat is blank; unsure if its getting power. Its a robertshaw 9420, operated by 24v, no batteries. AC/furnace are Rheem.
The main power switch is fully functional and there's power throughout the furnace (or so we've found so far there is.) Not sure what to look at next; suggestions?

Welcome to the forums.
Furnace..... as in gas furnace ? See if the control board has power. Most have a 24vac transformer feeding them.
The model number of the furnace would be helpful too.
(just a thought..... make sure the blower door is on correctly or nothing will work)
