Battery Problems

The first and most common reason behind the starting problem of the generator. Let me share why this happens and how to solve it.

Cause: A drained or disconnected battery is a common reason of starting issue of RV generator. The generator relies on the RV’s 12V battery for its initial power.
Solution: Check the battery voltage by using a multimeter. A fully charged battery should read around 12.6V. You can also recharge or replace the battery according to need.

Fuel Issues

Some Fuel Issues can also causes the starting issue of RV generator. Here is the cause and solution of it:

Cause: Low fuel levels or stale fuel can prevent the generator from starting. Many generators have a fuel shut-off feature when the tank is below 1/4.
Solution: Make sure that your fuel tank is above 1/4 full and also drain old fuel and replace the RV generator fuel with fresh gas or diesel depending on your generator type.

Clogged Air Filters

If you want to know Why Is My RV Generator Not Starting then you should check the air filters of your generator because Clogged Air Filters also cause the starting problem of RV generator.

Cause: Clogged Air Filters can cause the starting problem of RV generator because the dirty air filters can restrict the airflow which make it hard for the engine to start.
Solution: Check and clean or replace the air filter of generator as a part of regular maintenance.

Spark Plug Issues

Sometimes Spark Plug Issues can also cause the starting issue of generator. Here is why and how to solve it:

Cause: Spark Plug Issues can also cause the starting issue of generator because a worn-out or fouled spark plug can cause a weak or no ignition of generator fuel.
Solution: In order to solve this issue you have to remove the spark plug and check them for carbon deposits. If you found some carbon particles then you have to clean them properly or replace it with a compatible one for your RV generator.

Oil Levels and Sensor Issues

Oil Levels and Sensor Issues is also a big reason behind this issue of generator.

Cause: Low oil levels can have a negative effect on the generator’s safety sensor which can prevent the generator from starting.
Solution: Check the oil level and add the correct oil type if it is low. If oil is sufficient then the oil sensor may need adjustment or replacement.

Carburetor Problems

Sometimes problems occur in the Carburetor of the generator which causes difficulty in its starting.

Cause: Carburetors clogged with stale fuel or debris which can prevent the flow of fuel properly.
Solution: Clean the carburetor of generator with a carb cleaner or provide it a professional service.

Faulty Starter Motor

Some Faulty Starter Motor also prevents the RV generator from starting.

Cause: A damaged starter motor can result in the generator clicking but not starting issue.
Solution: Check the starter motor. If it is worn out or faulty then you have to replace it.

Electrical System Failures

Sometimes Electrical System gets Fail and cause this problem.

Cause: Loose wires, blown fuses or malfunctioning relays can interrupt the starting process of generator.
Solution: Check all the electrical connections and fuses. Replace blown fuses and make sure that the wires are properly secure.
