Rheem Heating & Cooling Customer FAQ

If your Rheem 8450TI-E pool heater is not starting, there could be a few possible reasons. It can be as simple as the breaker being off or your thermostat not being set high enough, so check these first. Also ensure the gas valve is open and the ignition is functioning properly. Make sure the pool pump is running and that the filter is not clogged. For safety reasons, if you continue to experience problems starting your pool heater, please get in touch with a professional for a detailed diagnosis to avoid any mishandling. These checks should be performed by a licensed technician to ensure safe and proper functioning.

The Marathon water heaters by Rheem come with a limited lifetime warranty on the tank and parts. This applies to the original owner and to single-family residential uses only. The warranty is effective provided the unit was properly installed and operated in accordance with the manufacturer's guidelines included in the installation instructions and use & care guide. For claims or specific conditions, it's recommended to review the warranty document that came with the heater or check the information from the place of purchase. The warranty does not, however, cover labor or any incidental, consequential or secondary damages.

If your Rheem air conditioner is broken and under warranty, it's recommended to contact the installer or dealer from whom you purchased the unit. Be ready to provide details about the issues you're experiencing, along with your unit's model number and proof of purchase. You should check your warranty for specific provisions as coverage can vary based on the model and time of purchase. Note that warranties typically cover parts defective due to manufacturing issues, not issues due to misuse or lack of maintenance.
