I am not familiar with that particular Carrier model number. There is a good chance that it may have a high and/or a low pressure cut-off switch inside the condensing unit. If you open up the control panel on it and look at any of the copper tubing that is accessible from the control box the switch would normally be about the size of a "C-cell" battery and it would have two wires coming off of it. Carrier likes to use both blue and yellow colored wires for their pressure switch circuits. Generally the low pressure switch is not manually resettable. If there Is a high pressure switch it would have a red button on it right between the two connection terminals. If you push it in and you hear or feel it click, then you know it was tripped. Otherwise the problem could be anything from a bad thermostat to a bad dual capacitor or even a bad or broken wire connection. The problem could even be at the furnace. I would recommend calling out a technician.

If you check my source Home Page go to the 'LINKS" page there and you will find a link to Carrier. You may be able to download a .pdf manual there.

Sounds like a fuse to me as well. there could be a fuse on circuit board and you could have some in the disconnect open disconnect and check for fuses and check for fuses at the circuit board the one on the board you can pull out and see inside if the small metal line is broken its bad

inside the furnace is a 3-5 amp fuse like in your car change it out with the same size if it still blows a fuse call a tech you have a low voltage short

tough one.i think you should call a repair man.check to see if your insurance covers it.good luck.
