A blown fuse is a relatively common problem in many air conditioning systems. When there is something wrong with the system, the fuse will often blow when the system cycle is on. Homeowners should not replace the fuse by himself, as that will not correct the underlying problem. A blown fuse means something is not working correctly in your system and needs to be repaired. Here are a few possible reasons your AC unit’s fuse has blown.
Problems with electrical connections, issues within the circuit or problems in the power supply may all cause a blown fuse. For safety measures, and to prevent damage to the unit, fuses are designed to blow when too much voltage moves through a line. Due to the complexity of electrical connections within an HVAC system, it is important to have an experienced technician diagnose these problems and make the repair.
The cooling system condenser contains a small part known as the capacitor, which functions to regulate the electrical current as it moves through the condenser. Problems with the capacitor lead to uneven flow of electricity, and ultimately can cause fuses to blow. Replacing the capacitor will correct this problem.
Regularly replacing your home’s air filters is important for your unit to work at maximum efficiency. When filters become clogged with dirt, the system works harder to push air, which ultimately takes a major toll on the unit. Combine this with particularly high temperatures, and the air conditioning system will have to work incredibly hard to keep the house at a comfortable temperature. The resulting strain on the unit can lead to blown fuses, which is why it’s crucial to keep your air filters clean and schedule regular maintenance calls for you HVAC system.
