9 Easy Steps on How to Bypass AC Float Switch

Step 1. Locate the Drain Plug:

Start by locating the drain plug on your AC unit, which is usually located near the bottom or back of the main housing. Be careful not to touch any of the coils or electrical components, as these can be extremely dangerous if handled improperly. You can use a wrench or screwdriver to loosen the plug, but be sure to hold onto it and keep it upright so that any water can drain out safely.

Step 2. Attach the Wire:

Once the drain plug is removed, carefully attach one end of your insulated wire to it and secure it with a clamp or large zip tie. Use your screwdriver or wrench to tighten this wire so no water can leak. Ensure that the wire is long enough to reach around the housing of your AC unit and into another outlet.

Step 3. Route the Wire:

Next, you’ll need to find an open and accessible spot on your AC unit’s housing where you can route your wire and attach it firmly in place. You might want to use a flathead screwdriver to create a small opening or notch that will hold your wire securely in place once it’s attached. Don’t worry about how your wire looks – this will not affect how it works.

Step 4. Connect the Wire to the Timer or Multimeter:

If you have a digital timer or multimeter, you can use this to track how often your AC unit is running. Simply connect the wire from your AC float switch bypass kit to the timer or multimeter and place it near the outlet that you routed your wire into. Be careful not to create any additional openings in your AC unit’s housing, as this could cause water damage or electrical injuries.

Step 5. Test the Bypass Kit:

Once all your wires are securely fastened and connected, test out your bypass kit by turning on your air conditioning unit. You should see that it works reliably, with no interruptions from the faulty float switch. This can help you determine how often you need to use your timer or multimeter for accurate tracking purposes.

Step 6. Maintain and Monitor Your System:

Now that you’ve successfully bypassed the AC float switch, it’s important to maintain and monitor your system to continue enjoying reliable cooling without worrying about costly energy bills. Some tips for maintaining your system include regularly changing the filters, cleaning any debris or ice buildup around the coils, and keeping an eye on the timer or multimeter to see how often your system is running.

Step 7. Contact a Professional if Needed:

If you notice that your AC unit is not working as well after bypassing the float switch, it may be time to contact a professional air conditioning repair technician for further assistance. They can help diagnose any underlying issues that may be causing problems in your system and ensure that it’s fully functional again in no time.

Step 8. Enjoy Cool Air and Lower Energy Bills:

With your AC float switch bypass kit successfully installed and maintained, you can enjoy the cool air that your AC unit provides without worrying about high energy bills. By monitoring how often your system is running and taking other steps to keep it in good condition, you can continue to save money on your utility costs for many years to come.

You should also check that all drains and other components are clear and functioning properly, and make sure to drain any excess water from your system as needed regularly.

If you continue to experience issues with your AC float switch after taking these steps, it may be worth consulting a professional for additional help and guidance. A skilled technician can assess your system, identify any underlying issues, and help you resolve them so that your AC float switch keeps working properly.

Overall, taking the right precautions when dealing with an AC float switch can help ensure the reliable operation of your cooling system for years to come. By proactively addressing any potential issues and troubleshooting problems as they arise, you can keep your system running smoothly and enjoy consistent comfort all year round.
