Generac Control Board Problems
While Generac control boards are designed to be reliable, they can experience problems. Here are some of the most common issues that you may encounter:
Failure to Start
One of the most frustrating issues you can experience with your generator is a failure to start. If you press the start button, and nothing happens, the problem could be a faulty control board. Other potential causes include a dead battery, a low oil level, or a bad starter motor.
Overloading
If your generator is overloaded, it can cause serious damage to your control board. Overloading occurs when you exceed the generator’s maximum power output, and it can cause the control board to overheat and fail.
Voltage Issues
Generac control boards are responsible for regulating the voltage output of your generator. If your generator is producing too much or too little voltage, the control board could be to blame. This issue can cause damage to your appliances and electronics and should be addressed immediately.
Frequency Problems
In addition to regulating voltage, control boards are also responsible for maintaining a consistent frequency. If your generator is producing a frequency that is too high or too low, it could cause damage to your electronics and appliances.
How to Identify Control Board Problems?
Now that you know the common issues that can occur with Generac control boards, let’s talk about how to identify them. Here are a few methods you can use:
Troubleshooting
The first step in identifying control board problems is to troubleshoot your generator. Check the oil level, ensure that the battery is charged, and inspect the starter motor. If you still can’t identify the issue, move on to testing.
Testing
If troubleshooting doesn’t reveal the issue, you’ll need to test the control board. You can do this using a multimeter to measure voltage and continuity. If you’re not comfortable doing this yourself, it’s best to hire a professional.
How to Fix Generac’s Generator Control Board Problems?
If you’ve identified an issue with your control board, you’ll need to take steps to fix it. Here are some potential solutions:
Resetting the Control Board
In some cases, resetting the control board can solve the problem. To do this, turn off the generator, disconnect the battery, and wait at least 30 minutes. Reconnect the battery and try starting the generator again.
Replacing the Control Board
If resetting the control board doesn’t resolve the issue, it may be necessary to replace it. However, replacing the control board is a more involved process and should only be attempted by those with experience or by a professional.
Before beginning the replacement process, it’s important to have the proper replacement control board for your generator model.
You can find this information in your generator’s manual or by contacting the manufacturer. To replace the control board, start by disconnecting the battery and any wires connected to the board. Then, remove the old board and install the new one, following the manufacturer’s instructions carefully to ensure a proper installation.
Once the new control board is installed, test the generator to ensure it’s functioning correctly. If you’re unsure about any aspect of the replacement process, don’t hesitate to contact a professional for assistance. A mistake during installation can cause further damage to the generator and create even more problems.
