Rheem furnace error code 5

If your Rheem furnace is giving you a 5 error code, it could be due to a range of different issues.

If the furnace is not heating up enough, it might be because the fan is not turning on or the thermostat unit isn’t working. If the heating element is too hot, check for a clogged or broken filter; if all else fails, call an HVAC specialist to inspect and repair your furnace.

The Rheem furnace error code 5 indicates that the thermostat is not working properly. It can be caused by a number of different problems including blocked vents and clogged ducts.

Rheem offers a variety of ways to fix such issues. The simplest way is to unplug the unit for 30 minutes before plugging it back in again. Another solution might be to install an additional thermostat or replace the old one altogether if there are no other options.

While some of the causes may be difficult to fix on your own, there are still some that you can resolve yourself.
