Central heat and air. Heat is gas. House got really warm and I switched from heater to a/c. I turned it off at the end of the night and the next morning it was really cold so I tried to turn the heater on and nothing at all happens. I tried to turn AC on and nothing happened. I looked for a fuse in the fuse box and didn't find one so I just flipped all of them and nothing helped. On the unit outside I checked the switch box to see if it had fuses in it but it didn't. The thirmostat still clicks and seems to work fine, but nothing else is doing anything at all. Is there a fix to this? Is there something I am missing like a re-set switch? Thanks in advance.

Does the furnace usually have an indicator light on, and is it on? If it is on, jumper the R and w contact at the furnace. If nothing happens, check the inducer blower.

If the light isn't on, it could be a small blade fuse on the control board.
