COMMON RHEEM ERROR CODES
Rheem furnaces and air conditioners utilize a digital or LED diagnostic display to provide a “window” into the system’s health. These codes are essential for identifying internal malfunctions before they lead to a complete system lockout.
Code 0: This indicates that the system is in standby mode, but if it persists while you are calling for heat or air, it can signal a failure in the thermostat communication.
Code 10: This signals a one-hour lockout due to a persistent ignition failure, often requiring a professional to inspect the flame sensor or gas supply.
Code 22: This represents a pressure switch stuck open, which is frequently caused by a blocked condensate drain or an obstruction in the flue pipe.
Code 33: This is a high-limit switch fault, a safety mechanism that triggers when the heat exchanger is overheating, usually because of a restricted air filter or a failing blower motor.
Code 55: This indicates an issue with the inducer motor, signaling that the fan responsible for clearing combustion gases is not reaching the required speed.
Code 93: This represents a control board failure or an internal memory error, meaning the “brain” of the system needs to be reset or replaced.

RHEEM HVAC FAQS
What does the "PlusOne®" feature on Rheem units mean?
Rheem’s PlusOne® features are design innovations that make the units easier to maintain and more reliable. This includes things like the “PlusOne Diagnostics” LED display and the “PlusOne Ignition System,” which is designed to be one of the most reliable ignition sources in the industry.
How often should I change the filter on my Rheem furnace?
For standard 1-inch filters, we recommend checking them every 30 to 60 days. If you have a high-efficiency Rheem system with a thicker media filter, you may only need to change it once every 6 to 12 months, depending on the air quality in your part of the Bay Area.
Why is water pooling around my Rheem indoor unit?
This is typically a sign of a clogged condensate drain line or a cracked drain pan. Rheem systems are designed to remove a significant amount of humidity from the air, and if that water has nowhere to go, it will overflow. We can clear this quickly and treat the line to prevent future clogs.
Do you install Rheem heating and cooling systems?
Yes. We install and repair Rheem air conditioners, heat pumps and gas furnaces and size new equipment to the house and ductwork.
Why does my Rheem furnace turn on and off quickly?
Short-cycling usually comes from a dirty flame sensor, a clogged filter, an overheating limit switch or a thermostat fault. We test the controls and fix the cause.
