A few beard trimmers can last for years, but some die out only after a few months. Usually, branded trimmers come with at least a year's warranty.
If you notice anything weird about the trimmer, you can go to the nearest service center and get it checked. But some of the local brands may promise to provide beard trimmers at low prices but without long-term warranties.
Whether it is a branded trimmer or a non-branded one, it is an electronic appliance, that one day will die out. But you should know the symptoms beforehand so that you can contact a service center before the trimmer becomes non-functional.
It usually starts with the trimmer's body getting hot. You may not pay much attention initially because appliances do get heated sometimes if you use them for too long. Don't ignore this sign from your beard trimmer. The body of the trimmer can get warm due to many reasons, such as defective wiring, old battery, or one of the parts malfunctioning. Whatever it is, you shouldn't use the trimmer further. Allow it to cool before you take it to a technician.
Most of the beard trimmers these days come with rechargeable batteries. Initially, the batteries last for hours, but over time, they start dying out faster. You will also notice that the battery is taking longer to charge up than before.
For example, a trimmer that could last for 15 hours after a charge of 60 minutes may last only for a couple of hours or less. It is a sign that you need to replace the battery or get a new trimmer.
Sometimes the blades of the trimmer don't budge at all. Even with the power on and the battery indicating a full charge, the blades won't move. This can be due to two reasons:
Too much dirt or hair between the blades will stop it from working properly. Every trimmer company asks its users to clean the blades frequently. Cleaning the blades is easy. You can detach them from the trimmer, clean them in water, and fit them back in their place.
If you are not sure how to do it, check the online personal care user manuals. They provide detailed instructions on how to clean trimmer blades. Some of the manuals also provide links to videos showing blade-cleaning techniques. Follow the techniques to make the blades work smoothly like before.
Apart from the blades, the handle of the trimmer can also get clogged due to residue buildup. It may cause the motor to heat up or stop it from working completely. Contact the nearest service center of the trimmer if you are not sure of how to clean the residue from the handle alone.
Beard trimmers don't last a lifetime. Repairing them, however, may increase their life. But you should know the symptoms before they die out so that you can get them repaired timely.
