A float switch is a device used in air conditioning units to automatically shut off the flow of water when the water level in the air conditioning unit reaches a certain level.
This is an important safety feature that prevents the unit from overflowing and potentially causing damage to the surrounding area.
The float switch is typically mounted on the side of the unit, and as the water level rises, the float attached to the switch will rise as well, eventually activating the switch and stopping the flow of water.
1. Locate the float switch on your AC unit. This may be inside the unit or near the outside condenser.
2. Use a flathead screwdriver to gently pry up the float switch tab.
3. Push the reset button on the float switch and then release it.
4. Replace the cover on the float switch and screw it back in place (if applicable).
5. Turn on your AC unit and check for proper operation.
Resetting ac float switch
To reset an AC float switch, follow these steps:
- Turn off the power to the air conditioning unit by switching off the circuit breaker or unplugging the unit.
- Locate the float switch on the side of the unit. It may be attached to a small plastic tube or rod.
- Use a small tool, such as a screwdriver or pliers, to gently push down the switch and reset it.
- Restore power to the unit and turn it on.
- Observe the unit to make sure it is operating properly and the water level is not rising to a dangerous level.
It’s important to note that resetting the float switch should only be done temporarily.
How Do I Reset My Air Conditioner’s Float Switch
Most air conditioners will have a reset button somewhere on the control panel.
This will usually be labeled as “RESET” or “RST”. If you cannot find the reset button, consult your air conditioner’s manual.
Once you have found the reset button, press and hold it for 3-5 seconds.
AC float switch won’t reset – What do you do?
If the float switch on your air conditioning unit won’t reset, there is likely an issue with the switch itself or the unit’s water level.
Here are some possible reasons why your float switch won’t reset, and what you can do about it:
- The float switch may be faulty. If so, you must replace the switch with a new one.
- The air conditioning unit may be overfilled with water. In this case, you’ll need to drain excess water from the unit to allow the float to move freely and reset the switch.
- The float may be stuck or obstructed. If this is the case, you may be able to free it by gently pushing or prodding it with a small tool.
- The unit may have a more serious issue, such as a clogged or damaged drain line. In this case, it’s best to contact a professional for assistance.
How do you unclog a float switch?
- First, turn off the AC unit’s power to avoid accidents.
- Next, locate the float switch and carefully remove it from the AC unit.
- Once the switch is removed, use a small brush or toothpick to gently clean any debris or clogs blocking the switch.
- If the switch is dirty or clogged, you may need a mild cleaning solution to help loosen and remove the debris.
- Once the switch is clean, carefully reattach it to the AC unit and turn the power back on.
- Finally, test the switch to ensure it works properly by activating it with the water level in the AC unit.

- Turn off the power to the air handler by switching off the circuit breaker or unplugging the unit.
- Locate the float switch on the side of the air handler. It may be attached to a small plastic tube or rod.
- Use a small tool, such as a screwdriver or pliers, to gently push down on the switch and reset it.
- Restore power to the air handler and turn it on.
- Observe the air handler to ensure it is operating properly and the water level is not rising to a dangerous level.
How do I know if my ac float switch is bad?
One way to determine if a float switch is bad is to check if the switch moves freely and if it activates when the water level rises or falls in the AC unit.
You can also test the switch with a multimeter to see if it functions properly.
Additionally, you can try cleaning or replacing the switch to see if that fixes the issue.
It’s also a good idea to check the rest of the AC unit to ensure no other issues could be causing the problem.
Why does my AC float switch keep tripping?
A float switch may trip repeatedly for several reasons. Some possible causes include a clogged or dirty switch, a malfunctioning switch, or a problem with the AC unit itself.
The best way to determine the cause of the issue is to inspect the switch and the AC unit carefully and test the switch with a multimeter.
If the switch is dirty or clogged, you can try cleaning it to see if that fixes the problem.
If the switch is malfunctioning, it may need to be replaced.
Additionally, it’s important to check the rest of the AC unit to ensure that there are no other issues that could be causing the float switch to trip.
You can simply bypass the float switch if necessary to avoid any hassle.
If your air conditioner is having trouble starting up, it may be because the float switch needs to be reset.
The float switch is a safety device that prevents the air conditioner from turning on if there is water in the unit.
To reset the switch, turn off the power to the unit and remove the access panel.
Locate the float switch and press the reset button.
Once the button has been pressed, you can turn on the power to the unit and try again.
