What is the blower fuse?
4 Answers
blower is the fuse for the air blower. The functions of the air blower are as follows: 1. Deliver hot air: It supplies the combustion chamber with the hot air required for combustion through the air preheater, and provides the hot air needed for drying and transporting pulverized coal to the coal pulverizing system through the primary fan and air preheater. The air delivered by the blower is heated air from the outlet of the air preheater, which is then delivered to the combustion chamber as secondary air, hence it is also called the secondary fan. 2. Balanced ventilation: The blower is the power device that delivers the air required for fuel combustion into the boiler, often using a centrifugal fan. In balanced ventilation, the blower must overcome all the resistance from the air duct entrance to the combustion chamber, including the resistance of the air preheater, air delivery pipes, grate, and fuel layer.
I also encountered a blower not working issue before, and it turned out to be a blown fuse. The blower is the component in the car that blows air, and the fuse specifically protects its circuit. It's usually located in the fuse box under the dashboard—just open the cover and look for one labeled "blower" or "fan." Checking it yourself is simple: use small tweezers to pull it out and see if the metal strip inside is broken. If it is, replace it with a new one of the same amperage. Remember not to use a higher-rated fuse, as it can easily damage the circuit. That time, I just spent five bucks on a new fuse and fixed the cold air issue. When driving daily, the worst fear is the blower failing when the windows fog up—that’s dangerous, so it’s important to check it regularly. If it’s another issue like a faulty switch, you’ll need to get a mechanic to help.
The blower fuse protects the motor from burning out. Let me teach you a quick fix. First, locate the fuse box, usually hidden inside the dashboard, and pull out the blower fuse to inspect. If it's blown, buy a replacement with the same amperage from an auto parts store—never tamper with the voltage. Last time I helped a neighbor, when the blower wasn't working, 80% of the time it was a fuse issue, but also check for poor wiring connections or shorts. If replacing it doesn't solve the problem, the motor might be dead. For safety, always disconnect the battery before working on it.
If the blower fan fails, the AC won't blow air. The fuse prevents motor overload. This happened in my car too - terrifying when windshield fogs up in winter. Pro tip: check fuses first if airflow stops. Located in the fuse box, just swap with a new one. But beware: aged wiring or short circuits may cause blowouts, so regular checks are wise. Ultimately a minor issue you can safely fix yourself quickly.
