But don’t panic; it’s not the end of the world. There are some simple and effective solutions that you can try to get your mower working again.
In this blog post, we will explain the possible causes and solutions for the flashing red light on your DeWalt lawn mower. By the end of this post, you will know how to troubleshoot and resolve this issue and how to prevent it from happening again. Let’s get started!
Possible Causes of a Flashing Red Light on Your DeWalt Lawn Mower
There are four main possible reasons why your Dewalt lawn mower may flash a red light. Among these are:
1. Low or dead battery
The battery does not have enough charge to power the mower. This is the most common cause of the flashing red light.
The battery status can be checked by looking at the LED indicators on the battery or the charger.
A blinking red light means that the battery is charging; a solid red light means that the battery is fully charged; and a blinking red and solid yellow light means that the battery is too hot or too cold and needs to reach the right temperature for charging.
2. Incompatible battery
The battery is not compatible with the mower model. Dewalt lawn mowers require specific battery models, such as the Dewalt 20-volt lithium-ion battery.
Using an incompatible battery may result in a voltage mismatch and an insufficient power supply. The mower may not recognize the battery or may flash a red light as a warning.
3. Defective battery
The battery is faulty or damaged and cannot hold a charge or provide adequate power. This may happen due to overcharging, overheating, or physical damage.
A defective battery may also cause the red LED to flash rapidly on the charger or the mower. Most defective batteries must be replaced, as they cannot be fixed.
4. Problematic charger
The charger is not working properly and cannot charge the battery fully or correctly. This may happen due to faulty wiring, a loose connection, or a power outage.
A problematic charger may also cause the red LED to flash rapidly on the charger or the mower. The charger should be checked and replaced if necessary, or contact the customer support service for assistance.
Possible Solutions for Flashing the Red Light on Your DeWalt Lawn Mower
Depending on the cause of the flashing red light, there are different solutions that you can try:
1. Fully charge the battery.
The simplest solution is to fully charge the battery using the appropriate charger. You can check the battery status by looking at the LED indicators on the battery or the charger.
A blinking red light means that the battery is charging; a solid red light means that the battery is fully charged; and a blinking red and solid yellow light means that the battery is too hot or too cold and needs to reach the right temperature for charging.
If the battery does not charge or hold a charge even after recharging, you may need to replace the battery with a new one.
2. Check the battery compatibility.
The best solution is to use a compatible battery that matches the mower model. You can find the compatible battery models in the user manual or on the Dewalt website.
For example, the Dewalt 20-volt lithium-ion battery is compatible with most Dewalt lawnmowers. You can also contact the customer support service for assistance.
3. Replace the defective battery.
The only solution for a defective battery is to replace it with a new one. You can buy a new battery from an authorized dealer or online. You can also check the warranty policy to see if you are eligible for a free replacement or repair.
3. Check the charger.
The last thing to do is to check the charger and make sure that it is plugged in properly and that there is no damage or dirt on the charger or the battery contacts.
You can also try using a different outlet or a different charger and see if that makes a difference. If the charger is still not working, you may need to replace it or contact the customer support service for assistance.
Tips to Prevent Flashing the Red Light on the Dewalt Lawn Mower
To avoid the flashing red light issue and extend the battery life and performance of your Dewalt lawn mower, here are some tips that you can follow:
1: Charge the battery fully before using the mower for the first time or after a long period of storage.
2: Store the battery in a cool and dry place, away from direct sunlight, heat sources, and moisture.
3: Do not overcharge or undercharge the battery. Follow the recommended charging time and frequency in the user manual.
4: Do not use the battery in extreme temperatures. The optimal operating temperature range is between 4°C and 40°C.
5: Do not drop, puncture, or expose the battery to water or fire. Handle the battery with care and avoid physical damage.
6: Clean the battery and the charger regularly and remove any dust or debris that may affect the contact or the airflow.
7: Recycle or dispose of the battery properly when it reaches the end of its life cycle. Do not throw the battery in the trash or the fire.
