Why RV Converter Fan Won’t Shut Off and Best Ways to Solve Them:

Everyone desires to have a converter fan that smoothly turns on and off. But if your RV converter fan isn’t shutting off at all, there is no chance to take it simply! 

Depending on the several conditions, the reason behind “not shutting off” will vary. So here, I’d like to share the 3 most common causes, including their quick fixes – 

1. Issues with the Battery 

Sometimes, your RV converter battery becomes unable to bear the loads. And that’s when you need to pay attention to the battery of your RV to see if everything is okay or not. 

Why? This is because poor battery cells are liable to decrease the voltage level and cause your converter won’t shut off.  

By taking assistance from a multimeter, you can check the level of voltage. If you found it 13.5+ and still running all the time, then the problem might be anywhere else as the converter fan is completely fine. 

In contrast, if the battery turns weaker, you’re likely to discover less than 12.6. Consider replacing the battery by taking the manufacturers’ advice and instructions.

2. Loose Wiring Connections 

Some of us often neglect the necessity of looking at the wirings of a converter fan, even after facing complications. But guess what? Loosen and broken wiring connections are known to be one of the core reasons why your RV fan won’t shut off! 

Although some converter fans of RV come in an automatic powering system, the power of converter fans often consist of dual wiring connections. Thus, it allows you to turn it on and off while needed. 

So, if there are any loose connections, especially on the shut-off wiring line, your RV fan will likely run all the time! In that case, consult an expert mechanic to fix the issue by tightening the connection. 

However, if the problem is related to a broken connection, you may have to replace it right away.

3. Extra Power Consumption 

Note that some 12V consumers take power through a fuse set instead of the circuit breaker. So chances are it is running the water heater, light, or refrigerator of your RV and causing the converter fan not to shut off. 

Fuse replacement might work at times to fix the actual issue. But you better take expert support to see why that’s consuming additional power than usual!
