If you need to know how to tell if an AC fuse is blown, there’s a good chance your AC just stopped working, and you’re starting to panic because the temperature is already rising. A blown fuse is one of the more common reasons that air conditioners stop working. It seems to happen out of nowhere.
Keep reading this informative blown fuse advice from Quality Heating, Cooling, Plumbing & Electric, a leading AC team that provides trusted AC repair in Owasso.
ACs, Fuses, and Owasso Heat
Air conditioners are made to fight heat because a fuse protects an AC’s high-tech engineering from excess currents. An air conditioner only works well when everything is balanced internally and with the fuse.
But ironically, high temperatures cause fuses to blow.
Signs That an AC Fuse Is Blown
Here are the signs to look out for:
- The AC blows hot air.
- The AC unit or breaker box makes odd noises.
- The AC keeps resetting.
- The air conditioner won’t start.
Don’t ignore these signs because you think a fuse is easy to repair or replace. If you let them go on, they overwhelm the AC, which harms the unit. Then you’re looking at a costly repair or replacement, which means more time in this Owasso heat without a working cooling system.
Therefore, you want to get the problem taken care of quickly. If it’s just a blown fuse, you can diagnose the problem and tell your AC repair team what you’ve discovered. They can double-check everything for you.
How To Tell If AC Fuse Is Blown
These steps explain how to tell if an AC fuse is blown. Following the steps keeps you safe from electrocution caused by a lack of knowledge and oversights.
Knowing how to tell if an AC fuse is blown means you need to get some tools, so grab:
- Safety glasses/goggles
- Insulated gloves
- A flashlight
- A screwdriver
- A non-contact voltage tester
Next, turn off the AC unit and its circuit breaker.
If you know where your fuse box is and the affected fuse, compare the old fuse to a new one. Unscrew the fuse box to see. A blown fuse almost always has a black spot or cracked filament. Sometimes it has both.
These signs show the fuse needs to be replaced.
If you don’t know where the fuse box is, look in the air conditioner owner’s manual. If you don’t have it, Google your AC’s owner manual. The fuse box could be on the outside unit or on a wall in the house.
The manual should tell you which fuse is which. Sometimes, they’re marked. Now you can compare the fuses if you couldn’t do it before.
Without touching the wiring, check if the wiring looks loose, as loose wiring causes the same symptoms as a blown fuse. Poor wiring causes dangerous electrical problems. A professional AC team can help with this.
Use the non-contact voltage tester to see if it senses any current. If the tester responds, the fuse still works. If it doesn’t, the fuse needs to be replaced.
The only safe way to replace an AC fuse is to hire a professional HVAC team to do it for you. Testing the fuse to see if it works requires a non-contact tool, so imagine what replacing one requires.
Replacing a fuse is not a DIY project because, besides the danger, your property could sustain thousands of dollars in damage.
