Why Your Whole House Generator Won’t Start

If you’ve got a whole house generator, it’s important to make sure that it’s properly working. Otherwise, you’re putting yourself and your family at risk of dangerous conditions.

A common problem that can cause your whole house generator to not start is a low fuel level. This can happen if you haven’t refilled the tank in a while or if the fuel is old and stale.


If you have a whole house generator that has been sitting idle for too long, the battery can become drained and the generator won’t start. That’s why it’s important to turn your generator on from time to time and let it run for a few minutes so that you can make sure the battery is in good shape.

The next step is to try charging your battery. This can be done by connecting a 12-volt DC outlet to your generator and running it for a few minutes, or you can also use jumper cables to charge the battery.

A whole house generator can be a great way to keep your family comfortable during power outages. Whether you’re concerned about food spoiling in the freezer, kids needing medical equipment like oxygen or dialysis machines, or even keeping your HVAC system on, you can rely on your generator to give you and your family peace of mind when the power goes out.


If your whole house generator won’t start, it could be due to a number of things. One of the first things you’ll want to check is the fuel tank and its connections. If the line to your fuel tank is clogged, it might not deliver the fuel your generator needs.

Another issue that might be preventing your generator from starting is a faulty fuel gauge. This can cause the mechanical gauge to stick, giving a false fuel level indication.

Alternatively, the fuel pump might not be working properly or the lines might be clogged with ice or dirt. If this is the case, you’ll need to replace the pump or rewire the generator.

Whether you’re looking for natural gas, liquid propane, diesel or gasoline, your best bet is to choose a tri-fuel generator that has the ability to switch between these different fuels as needed. This way, you’ll have a back-up power source regardless of what happens.


The exhaust in a vehicle takes the gas, particulate matter, and smoke from your car’s engine and expels it through the tailpipe. This is an essential element of your car’s performance, as it helps to remove waste from the system and keeps your car clean and healthy.

Whole house generators also have exhaust pipes that take the fumes away from your home, reducing the risk of airborne pollutants entering your living space. The exhaust and ventilation systems of a whole house generator are usually encased in a sound deadening protective enclosure that keeps the gases from escaping into your home, and they’re located outside your house.

If your whole house generator won’t start, you could have an issue with the exhaust. This might be a sign of cracks or leaks, and you may need to replace the part. Check for rust spots when you’re inspecting your generator.

Control Panel

The control panel of a whole house generator is the key to powering your home during an outage. The controls allow you to change settings such as oil pressure, coolant temperature and battery voltage.

The panel is a combination of gauges and meters that display information about various parameters like voltage, current and frequency. It also features buttons and switches that make it easier to operate the generator.

Generators typically come with a control panel that has been designed and built by the manufacturer of the generator. However, it is possible to purchase a custom-made control panel that will meet your specific needs.

The control panel is a critical part of your generator, so you should always take the time to research the model you have and its control capabilities before making a purchase. The right choice is crucial to maximizing your equipment’s performance, efficiency and safety during an outage.
