Rheem HVAC Troubleshooting & Solutions
Arlington’s Certified Experts for Rheem Classic® & Prestige® Series
Rheem systems are known for their industry-leading efficiency and the advanced EcoNet® smart technology. However, when errors occur, they require precise diagnostics. Use our guide below to troubleshoot common issues.
❄️ Cooling & Heat Pumps
Issue: Frozen Coils or Poor Cooling
Often caused by dirty filters, low refrigerant, or a defrost sensor failure in heat pumps.
🛠 DIY Fix: Thaw the unit by turning off the AC and running the fan only. Replace the air filter.
✅ Legend Air Fix: We perform EcoNet® system scans to pinpoint sensor failures and recharge refrigerant to factory specs.
🔥 Rheem Furnace Support
Issue: Ignition Failure (Error Code 67)
Commonly a dirty flame sensor or a hot surface igniter that has reached the end of its life.
🛠 DIY Fix: Ensure the gas valve is open and your thermostat has fresh batteries.
✅ Legend Air Fix: We replace Rheem-specific igniters and clear pressure switch blockages for reliable winter heating.
EcoNet® Smart Diagnostics
Modern Rheem systems use the EcoNet® control board. If your thermostat is displaying a “Service Required” alert or a specific numerical error code, do not attempt to bypass the wiring. Our techs are trained in Rheem digital diagnostics to fix it right the first time.
