My heater had been acting up. It does turn on after a while of turning my thermostat on and off. It turns on and I hear one click but then my furnace just shuts off. I checked the tubes and blew into it and they are all clean. What else can I do? Should I just replace the switch?

Any help will be appreciated!
Thank you

Look to see if it is flashing an error code. What brand and model number is your furnace.
