Just to confirm: with central air conditioning, there are typically 2 circuit breakers: one for the inside blower unit (which is obviously working), and one breaker set for the outdoor unit. It's this second "double breaker" I'd look at first. Often, breakers trip and don't look like they're tripped. The only way to check for sure is to switch the breaker off, looking for a solid "click," and then turning it back on again. If nothing still runs outside, the possible culprits are as follows:
1. If the "condensate" -- the moisture removed at the indoor evaporator coil -- is routed to a "condensate pump," it may be that that pump's sump is full. Is the condensate pump energized? Does it have a "safety switch" that shuts off the air conditioner if the sump fills up? If the pump's sump is full, and there's power to the pump, then the condensate pump may need to be replaced.
2. Burnt/broken power or control wiring to the outdoor unit.
3. Burnt/broken contactor in the outdoor unit.
4. Deluxe outdoor unit senses a loss of refrigerant and shuts itself off (via the "low pressure safety" control).
5. Failed outdoor fan motor has overheated the compressor, so neither runs.
6. Failed compressor (due to internal failure or problems in the start components or burnt/broken wiring at the compressor terminals) keeping the compressor off. The condenser fan motor is kept off by a "condenser fan cycling control" which normally starts it after the compressor has built up refrigerant pressure.
What else can I help you with?
What could be the reason why my central air fan is not working?
The central air fan may not be working due to a faulty motor, a blown fuse, a tripped circuit breaker, or a malfunctioning thermostat.
Why won't my central air turn on and how can I troubleshoot the issue?
There could be several reasons why your central air won't turn on. Some common issues include a tripped circuit breaker, a faulty thermostat, or a problem with the air conditioning unit itself. To troubleshoot the issue, you can start by checking the circuit breaker to ensure it hasn't tripped. Next, make sure the thermostat is set correctly and functioning properly. If those steps don't solve the problem, you may need to contact a professional HVAC technician to diagnose and repair the issue.
Why is my central air not turning on?
There could be several reasons why your central air is not turning on. It could be due to a tripped circuit breaker, a faulty thermostat, a clogged air filter, or a malfunctioning compressor. It is recommended to check these potential issues or contact a professional HVAC technician for further assistance.
Why is my central air unit not turning on?
There could be several reasons why your central air unit is not turning on. It could be due to a tripped circuit breaker, a faulty thermostat, a clogged air filter, or a malfunctioning capacitor. It is recommended to check these components first before seeking professional help.

Why is my central AC compressor not turning on?
There could be several reasons why your central AC compressor is not turning on. Some common causes include a faulty thermostat, a tripped circuit breaker, a blown fuse, or a malfunctioning capacitor. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.
Why is my central air compressor not turning on?
There could be several reasons why your central air compressor is not turning on. Some common causes include a tripped circuit breaker, a faulty thermostat, a malfunctioning capacitor, or a problem with the compressor itself. It is recommended to contact a professional HVAC technician to diagnose and fix the issue.
When replacing an old thermostat on a central air unit for home do you need to turn the electric off?
It is recommended to turn off the power to the central air unit before replacing the thermostat to avoid any electrical shocks or short circuits. This can be done at the circuit breaker or by switching off the power to the unit directly.
Can I use my old central air conditioner's circuit to power a new hot tub?
The capacity of the breaker in amperage and the size of the wire connected to the breaker of the A/C circuit must be stated along with the total load of the new hot tub. Only then can an answer be given.
What is meant by mcb and dp?
MCB stands for Miniature Circuit Breaker, which is a type of electrical switch that automatically disconnects a circuit in case of an overload or short circuit. DP stands for Distribution Point, which refers to a location where multiple connections from a central source are distributed to different devices or equipment.
