-
Rheem Tankless Water Heater Secondary Heat Exchanger Replacement
Low outlet temp, error 29, water leaks, poor hot water flow, and visible corrosion mean your secondary heat exchanger has failed. Replacing it restores proper heating and clears the fault.
-
Rheem Tankless Water Heater Control Board Replacement Guide
Persistent error codes, ignition failures, no heating, or unresponsive controls mean your PCB is faulty. Replacing the control board restores normal operation after you rule out sensors and wiring.
-
Rheem Tankless Water Heater Flame Sensor Replacement Guide
Flame proving errors, unit won't ignite, shuts off mid-cycle, or carbon buildup on rod? Replacing the flame sensor fixes detection faults.
-

Low gas supply or a latched control fault. For LPG, check propane bottle level, cycle power at the outlet, and reopen the tap.
-
Rheem Water Heater Leaking - Causes & Fix
Usually a faulty T&P relief valve or loose pipe connection. Inspect the valve, connections, and tank seams to find the source.
-
Rheem Water Heater Water Too Hot - Causes & Fix
Usually a failed outlet temperature sensor or mineral scale buildup in a tankless unit (error code 16). Inspect the sensor and flush the heat exchanger.
-
Rheem Water Heater No Hot Water - Causes & Fix
Most often caused by ignition failure, flame loss, or insufficient water flow. Check the fault code on your unit's display first.
-
Rheem Water Heater Not Enough Hot Water - Causes & Fix
Usually caused by excessive demand or low flow rates. Check for simultaneous usage, verify minimum flow on tankless units, and flush sediment.
-
Rheem Furnace Blower Won't Shut Off - Causes & Fix
Usually the thermostat fan switch is set to ON instead of AUTO, or there's a shorted wire between R and G creating a constant fan call.
-
Rheem Furnace Igniter Not Working - Causes & Fix
Most often the igniter element has cracked or failed open. Test it with a multimeter at the leads for continuity and replace if open.
-

Most often the thermostat fan is set to ON instead of AUTO, running the blower constantly with no heat call. Switch to AUTO first.
-
Rheem Furnace Won't Turn On - Causes & Fix
Most often a dirty flame sensor or air filter causing the unit to lock out on ignition failure, flame loss, or limit trip.
-
Rheem Furnace Not Heating - Causes & Fix
