Ac Blowing Inside But Outside Unit Not Running [Solved]

ByRalph P. Sita Updated onFebruary 2, 2025

If your air conditioning system is functioning inside your home but the outside unit is not operating, several key issues may be at play. The primary suspect is often a tripped circuit breaker or a blown fuse, which prevents the outside condenser from receiving power. Another potential cause could be dirty condenser coils, which can impede the unit’s efficiency and require a thorough cleaning. Additionally, low Freon levels could be affecting your AC system’s performance, necessitating a recharge to restore its cooling capabilities. Addressing these issues promptly can help ensure your air conditioning unit functions optimally.

Why is My Air Conditioner Running Inside But Not Outside?

There are a few possible explanations if your air conditioner is running inside but not outside.

The most likely explanation is that the condenser, which is located outside, is not working. This could be because of a power outage, a blown fuse, or a tripped circuit breaker.

The entire air conditioning system will not work if the condenser is not working.

Another possibility is that the evaporator coil, which is located inside the house, is frozen.

This can happen if the air conditioner is set too low or if there is insufficient airflow over the coil.

A frozen evaporator coil will cause the air conditioner to run but not cool properly.

If your air conditioner is running but not cooling properly, check the thermostat to make sure it’s set correctly.

If the problem persists, contact a qualified HVAC technician for assistance.

How Do I Reset My Outside Ac Unit?

If your outside AC unit has stopped working, you may need to reset it.

To do this, first make sure that the unit is turned off.

Next, locate the reset button on the unit.

It is usually located near the bottom of the unit and may be hidden behind a small door.

Once you have found the reset button, press it in and hold it for about 5 seconds. You should then hear a click as the unit resets itself.

You may need to call a professional for help if the unit does not reset.

Outside Unit Running But Inside is Not

If your outside unit is running but your inside unit isn’t, there are a few potential causes.

One possibility is that the circuit breaker has tripped. Another is that the furnace switch is turned off.

If neither of these is the case, the issue may lie with the thermostat itself.

If you suspect that the problem lies with the circuit breaker, check to see if it has been tripped. If so, simply reset it and see if that solves the problem.

If not, you may need to replace the breaker altogether.

As for the furnace switch, this is usually located near your furnace or air handler. Simply ensure that it is in the “on” position.

If it appears to be fine, then check to see if there’s power going to it by testing for continuity with a multimeter.

Finally, if none of these solutions work, then it’s likely that you have a problem with your thermostat itself.

The first thing to do is try replacing the batteries; sometimes this can be enough to fix things.

Why is My Outside Unit Not Running When the Heat is on

If your outside unit is not running when the heat is on, there are a few things that could be happening.

First, check to make sure that the thermostat is set to “heat” and that the temperature is set correctly.

Next, check the breaker or fuse box to make sure that the circuit for the air conditioner is not tripped or blown.

If everything looks good there, it’s possible that the problem lies with the air conditioner itself.

There are a few different issues that can cause an air conditioner to fail to turn on when it’s supposed to.

One possibility is that the compressor isn’t working properly.

This can happen if the compressor isn’t getting enough power, it’s overheating, or there’s something wrong with the internal components.

Another possibility is that there could be a problem with the fan motor. If the fan motor isn’t working properly, it can prevent airflow over the coils, which will cause them to freeze up.

If your outside unit still isn’t running after checking all of these things, it’s best to call a professional for help.

They will be able to diagnose and repair any problems with your air conditioner, so you can get back to feeling comfortable in your home again!
