Compressor shorted to ground. (will need a new compressor).
Dirty furnace filter
Tripped AC Breaker (If your AC is not coming on I would suggest turning the breaker completely off and back on again to make sure the breaker is on. Do not touch anything metal on your circuit breaker box for safety).
I wanted to post this because many people are telling me that they are sucking on the pressure switch tubing to test pressure switch operation. I have heard from other forums that you should not suck on the pressure switch to test it because this can damage the diaphragm inside the pressure switch. It would be best to use a manometer or test with a volt meter like we advise on the following page: https://arnoldservice.com/how-to-test-and-troubleshoot-gas-furnace-pressure-switches/ I wanted to pass this along so others will not damage pressure switches.

I remind myself of a terrible experience I had several years ago when I brought my desktop computer in from a cold car, plugged it in and fried the mother board! I found out the hard way that it is always a good idea to allow an electronic part like control boards, pressure switches, televisions, laptops, etc. to warm up to room temperature before applying power. If you bring anything in from the cold outdoors into a warm home, condensation (water) will form on the part. We all know that water is a conductor. We can see why so many electronic parts can get destroyed if we do not allow them to warm up before applying power. I would strongly suggest that we allow the electronic parts and devices to sit for a couple of hours for warm up. This allows time for the water condensation to evaporate before applying power. I hope this will save you and others from problems.
