How to Troubleshoot Propane Generator Problems

Propane generators are used for a variety of purposes, from camping to recreational vehicles. They function as power sources, just like a standard generator, only they use propane instead of the more commonly used gasoline. Some people prefer propane over gasoline, because it is less expensive. If your propane generator is not working properly, there are some troubleshooting tips to try in hopes of isolating and repairing the problem.

Note: Be sure that the generator is turned off before doing any troubleshooting.

• Read through the instruction manual and check your equipment. Many issues with propane generators result from improper use and/or setup. Double check to make sure that the generator components are set up correctly. The manual should outline and diagram the proper setup.


• Check the tank level. Though obvious, some people may neglect to check on this important factor. If the tank is empty or sometimes near empty, the generator will not function properly.


• Check for leaks. Propane is nearly odorless, but if you notice a distinct, unusual smell coming from the generator, it is a strong indicator of a leak somewhere.


• Check the generator for an unusually high temperature. If the generator becomes too hot, a safety mechanism will engage, causing the machine to stop functioning. Propane generators come with a temperature gauge. If the generator starts then shuts off suddenly, check the gauge immediately after it turns itself off and note the temperature. A temperature of over 200 degrees Fahrenheit is considered high. Check your coolant levels and refill coolant as needed.


• Check the air filter. If there is any debris or other foreign object obstructing the intake vent, it will cause malfunction.


• Check the oil level. It may be low, especially if it has been several months since the oil has been changed.


• Examine the device that is being powered by the generator and make sure the wattage requirement is appropriate. It may be over exerting the generator itself. For example, a 500 watt generator should not be used to power a 1,000 watt device.


• Check for any blown fuses or loose electrical connections inside the generator. Blown fuses will have to be replaced. Loose connections may simply need just a quick reconnection.
