Rheem 80 furnace error codes

Rheem 80 furnace error codes were introduced as a way to simplify the troubleshooting of the Rheem 80-gallon natural gas furnaces.

With so many components and moving parts, it can be hard to figure out what is going wrong with your furnace. This could lead to expensive repairs and premature shutdowns.

Rheem introduced its error codes for customers looking for ways to prevent costly errors or prematurely shutting down their furnaces.

When you get an error code or notice the furnace will not start, there are a few things to pay attention to that will help you troubleshoot the issue.

The first step is to reset the circuit breaker by turning it off and then back on again. If that doesn’t work, you should contact customer service. If that doesn’t work, make sure someone is home to let the furnace know when it needs to shut down again.

If these solutions don’t work for you, call your local Rheem Dealer for assistance
